Question 1:

A nurse is caring for a 3-year-old child admitted with suspected meningitis. Which of the following signs would the nurse expect to assess in this patient if bacterial meningitis is the cause?

A. Fever. B. High-pitched cry. C. Altered mental status. D. Weight loss. E. Stiff neck.

Answer and Explanation

Choice A:

Fever is a common sign of meningitis, regardless of its cause. It is often accompanied by other symptoms such as headache and irritability.

Choice B:

A high-pitched cry is a classic sign of meningitis in infants and young children, especially in bacterial meningitis cases. The inflammation in the meninges can cause irritation of the central nervous system, leading to this specific cry.

Choice C:

Altered mental status is a significant sign of meningitis, especially when bacterial pathogens are involved. It can range from lethargy and confusion to more severe manifestations like seizures and coma.

Choice D:

Weight loss is not typically associated with meningitis. The condition usually presents with acute symptoms such as fever, headache, and neck stiffness, rather than chronic symptoms like weight loss.

Choice E:

A stiff neck is a hallmark sign of meningitis, particularly in cases of bacterial meningitis. It is caused by the irritation and inflammation of the meninges surrounding the spinal cord.

Question 2:

A nurse is educating a group of parents about meningitis and its transmission. Which of the following statements by the nurse is accurate regarding the transmission of viral meningitis?

A. "Viral meningitis is usually transmitted through ingestion of raw or undercooked snails or slugs.” B. "The vector of viral meningitis is the infected person, and the reservoir is the human body.” C. "Viral meningitis can be caused by Neisseria meningitidis and Streptococcus pneumoniae.” D. "Viral meningitis is usually transmitted through direct contact with respiratory droplets.” E. "The vector of viral meningitis is the fungus, and the reservoir is the environmental source.”

Answer and Explanation

Choice A:

Ingestion of raw or undercooked snails or slugs is associated with a parasitic infection called "rat lungworm" and not viral meningitis.

Choice B:

While the infected person can act as a vector for the spread of viral meningitis, the primary mode of transmission is through respiratory droplets and not the human body itself. The reservoir for viral meningitis is often human carriers, but it can also exist in other animals or environmental sources.

Choice C:

Neisseria meningitidis and Streptococcus pneumoniae are bacterial pathogens that can cause bacterial meningitis, not viral meningitis.

Choice D:

Viral meningitis is usually transmitted through direct contact with respiratory droplets. It can also be spread through contact with fecal matter and other body fluids. In contrast, bacterial meningitis has multiple routes of transmission, including respiratory droplets, direct contact, and contaminated food or water.

Choice E:

Viral meningitis is not caused by a fungus, and environmental sources are not the reservoirs for viral meningitis transmission. It is mainly transmitted from person to person.

Question 3:

A client with suspected meningitis presents with fever, headache, stiff neck, and photophobia. Which statement by the nurse is appropriate for this situation?

A. "Based on your symptoms, it is likely that you have viral meningitis.” B. "Your symptoms indicate that you might be suffering from bacterial meningitis.” C. "I think you might have fungal meningitis due to your chronic symptoms.” D. "It is possible that you have parasitic meningitis, given your exposure to contaminated water.” E. "Your symptoms suggest that you have meningococcal septicemia.”

Answer and Explanation

Choice A:

This statement is not appropriate because it assumes a specific diagnosis without further assessment or confirmation. Meningitis can be caused by various pathogens, so it's essential not to jump to conclusions based solely on symptoms.

Choice B:

This statement is appropriate because the patient's symptoms, including fever, headache, stiff neck, and photophobia, are consistent with bacterial meningitis. Bacterial meningitis is a severe infection that requires prompt treatment to prevent complications.

Choice C:

This statement is not appropriate because fungal meningitis typically presents differently and is more common in individuals with compromised immune systems. There is no evidence from the presented symptoms to suggest fungal meningitis.

Choice D:

This statement is not appropriate because parasitic meningitis is very rare and typically associated with specific exposures or travel history. There is no information to support this as a likely cause of the client's symptoms.

Choice E:

This statement is not appropriate because meningococcal septicemia is a different condition from meningitis. While both can be caused by Neisseria meningitidis bacteria, septicemia is characterized by a bloodstream infection, while meningitis affects the meninges.

Question 4:

A nurse is assessing an older adult patient for possible meningitis. Which of the following symptoms would the nurse be particularly concerned about in this age group?

A. Nuchal rigidity. B. Rash. C. Irritability. D. Altered mental status. E. Photophobia.

Answer and Explanation

Choice A:

Nuchal rigidity (stiff neck) is a classic symptom of meningitis, but it is not particularly concerning in older adults as it is in younger individuals. Older adults may have a less pronounced neck stiffness due to age-related changes.

Choice B:

Rash can be a symptom of certain types of meningitis, such as meningococcal meningitis, but it is not specific to older adults. Moreover, older adults may not exhibit a rash even in cases of meningococcal meningitis.

Choice C:

Irritability is a vague symptom and may not be specific to meningitis in older adults. It can be caused by various factors and does not raise significant concern for meningitis.

Choice D:

Altered mental status, such as confusion, delirium, or decreased level of consciousness, is particularly concerning in older adults with suspected meningitis. Older adults may not always present with classic symptoms like neck stiffness, and altered mental status may be the primary indicator of central nervous system involvement.

Choice E:

Photophobia is a common symptom of meningitis, but it is not specific to older adults. It may be present in both younger and older patients with meningitis.

Question 5:

A client is admitted with suspected meningitis, and the healthcare provider orders a lumbar puncture to obtain cerebrospinal fluid (CSF) for analysis. Which of the following statements is accurate regarding this procedure?

A. "The lumbar puncture involves the insertion of a catheter into the blood vessels near the spine to collect CSF.” B. "The lumbar puncture is done to assess the presence of bacterial or viral infections in the CSF.” C. "The lumbar puncture is a painful procedure and requires general anesthesia.” D. "During the lumbar puncture, you will be asked to bend your neck forward to facilitate the insertion of the catheter.”

Answer and Explanation

Choice A:

This statement is incorrect. A lumbar puncture involves the insertion of a needle, not a catheter, into the subarachnoid space of the spinal canal to collect cerebrospinal fluid (CSF) It is not done in blood vessels.

Choice B:

This statement is accurate. A lumbar puncture is performed to obtain a sample of cerebrospinal fluid for analysis. It helps to diagnose and differentiate between bacterial and viral meningitis based on CSF characteristics, such as cell count, glucose levels, and presence of bacteria or viruses.

Choice C:

This statement is incorrect. A lumbar puncture is uncomfortable but is typically not an extremely painful procedure. It is often done with local anesthesia, and the discomfort is usually temporary.

Choice D:

This statement is incorrect. During a lumbar puncture, the patient is usually asked to curl up in a fetal position, bringing the knees close to the chest and the chin to the chest. This position helps to widen the spaces between the spinal bones, making it easier for the healthcare provider to insert the needle into the subarachnoid space. It does not involve bending the neck forward.

Question 6:

. Which bacteria are most commonly responsible for bacterial meningitis in adults?

A. Haemophilus influenzae type b (Hib) B. Neisseria meningitidis (meningococcal) C. Streptococcus pneumoniae (pneumococcal) D. Escherichia coli. E. Group B streptococcus.

Answer and Explanation

Choice A:

Haemophilus influenzae type b (Hib) was a common cause of bacterial meningitis in the past, especially in children, but its incidence has significantly decreased due to the widespread use of the Hib vaccine.

Choice B:

Neisseria meningitidis (meningococcal) can cause meningitis and is an important pathogen, but it is more commonly associated with meningitis in children and young adults.

Choice C:

Streptococcus pneumoniae (pneumococcal) is the most common cause of bacterial meningitis in adults. It is a gram-positive bacterium that can lead to severe infections, including pneumonia, meningitis, and bloodstream infections.

Choice D:

Escherichia coli is a bacterial species typically associated with urinary tract infections and gastrointestinal illnesses. While it can rarely cause meningitis in certain populations, it is not the most common cause of bacterial meningitis in adults.

Choice E:

Group B streptococcus is a significant cause of neonatal meningitis but is less commonly responsible for meningitis in adults.

Question 7:

. What is the primary mode of transmission for viral meningitis?

A. Ingestion of contaminated water. B. Mosquito or tick bites. C. Direct contact with respiratory droplets or saliva. D. Inhalation of fungal spores. E. Contact with contaminated soil.

Answer and Explanation

Choice A:

Ingestion of contaminated water is the primary mode of transmission for certain gastrointestinal infections, such as viral gastroenteritis, but it is not the main route for viral meningitis transmission.

Choice B:

Mosquito or tick bites are associated with the transmission of various vector-borne diseases, such as West Nile virus, Lyme disease, and others. However, they are not the primary mode of transmission for viral meningitis.

Choice C:

Direct contact with respiratory droplets or saliva from an infected person is the most common mode of transmission for viral meningitis. Viruses causing meningitis, such as enteroviruses, are often present in respiratory secretions and saliva.

Choice D:

Inhalation of fungal spores is related to the transmission of certain fungal infections, such as aspergillosis or histoplasmosis, but it is not the primary mode of transmission for viral meningitis.

Choice E:

Contact with contaminated soil is not a typical mode of transmission for viral meningitis. It might be relevant for some soil-transmitted infections but not for viral meningitis.

. What is the most common and severe type of meningitis in infants and children?

A. Bacterial meningitis. B. Fungal meningitis. C. Viral meningitis. D. Parasitic meningitis. E. Meningitis of unknown origin.

Answer and Explanation

Choice A:

Bacterial meningitis is the most common and severe type of meningitis in infants and children. The causative bacteria can include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae type b, among others.

Choice B:

Fungal meningitis is less common than bacterial meningitis and is usually associated with specific risk factors, such as immunosuppression or exposure to certain environmental fungi.

Choice C:

Viral meningitis is more common than bacterial meningitis, but it is usually milder and often resolves without specific treatment. Enteroviruses are the most frequent cause of viral meningitis in infants and children.

Choice D:

Parasitic meningitis is a rare form of the disease and is usually associated with specific parasites, such as the amoeba Naegleria fowleri or the parasite Trypanosoma.

Choice E:

Meningitis of unknown origin refers to cases where the cause of meningitis remains unidentified after thorough investigations. It is not a specific type of meningitis but rather a descriptive term for cases with uncertain etiology.

Question 9:

A nurse is caring for a client suspected of having meningitis. What is the most important laboratory test to confirm the diagnosis?

A. Blood culture. B. Throat swab. C. Lumbar puncture. D. Computed tomography scan.

Answer and Explanation

Choice A:

A blood culture is a test used to detect bacteria or other microorganisms in the bloodstream. While it can be helpful in diagnosing bacterial infections, it is not the most important test for confirming meningitis. The presence of bacteria in the blood does not necessarily confirm meningitis, as the infection may not have spread to the bloodstream yet.

Choice B:

A throat swab is used to collect samples from the throat to identify infections such as strep throat. While throat infections can sometimes lead to complications like meningitis, a throat swab is not the most important test for confirming the diagnosis of meningitis. The infection may not be present in the throat, and direct examination of cerebrospinal fluid is necessary to confirm meningitis.

Choice C:

A lumbar puncture, also known as a spinal tap, is the most important laboratory test to confirm the diagnosis of meningitis. It involves collecting a sample of cerebrospinal fluid (CSF) from the space around the spinal cord and brain. Analysis of the CSF can reveal the presence of bacteria or other pathogens, increased white blood cells, and other indicators of meningitis.

Choice D:

A computed tomography (CT) scan is a diagnostic imaging test that uses X-rays to create detailed cross-sectional images of the body. While it can help identify structural abnormalities in the brain, such as bleeding or tumors, it is not the primary test for confirming meningitis. CT scans may show signs of inflammation, but they cannot definitively diagnose meningitis or distinguish between bacterial, viral, or fungal causes.

Question 10:

(Select all that apply): A nurse is providing care for a client with meningitis. What are the appropriate nursing interventions for this client? (Select all that apply)

A. Administering intravenous fluids. B. Applying warm compresses to the forehead. C. Providing dim lighting and minimizing noise. D. Giving prophylactic antibiotics. E. Monitoring vital signs and neurological status.

Answer and Explanation

Choice A:

Administering intravenous fluids is an appropriate nursing intervention for a client with meningitis. Meningitis can cause dehydration due to fever, decreased oral intake, and increased fluid loss. IV fluids help maintain hydration and prevent complications.

Choice B:

Applying warm compresses to the forehead is not a standard nursing intervention for meningitis. Fever is a common symptom of meningitis, and while comfort measures may be used to manage fever, warm compresses on the forehead are not specific to meningitis and may not be well-tolerated by some patients.

Choice C:

Providing dim lighting and minimizing noise are appropriate nursing interventions for a client with meningitis. Meningitis can cause sensitivity to light and sound, and creating a calm and quiet environment can help reduce discomfort and promote healing.

Choice D:

Giving prophylactic antibiotics is an appropriate nursing intervention for bacterial meningitis. Once the diagnosis of bacterial meningitis is confirmed or suspected, antibiotics should be initiated promptly to control the infection and prevent complications.

Choice E:

Monitoring vital signs and neurological status is crucial for a client with meningitis. Vital signs such as temperature, heart rate, respiratory rate, and blood pressure should be closely monitored to assess for any signs of worsening condition or complications. Neurological assessments help identify changes in the client's mental status, reflexes, and cranial nerve function.

Question 11:

A nurse is assessing the cerebrospinal fluid (CSF) of a client suspected to have meningitis. Which CSF parameter indicates bacterial or fungal infection?

A. Cloudy appearance. B. Increased pressure. C. Decreased glucose. D. Elevated protein levels.

Answer and Explanation

Choice A:

A cloudy appearance of cerebrospinal fluid (CSF) can indicate the presence of white blood cells and bacteria, suggesting an infection. However, it is not specific to bacterial or fungal infection and can also be seen in viral meningitis or non-infectious conditions like multiple sclerosis.

Choice B:

Increased pressure in the CSF may occur in meningitis due to the inflammation and accumulation of fluid. While it can raise suspicion for meningitis, it is not specific to bacterial or fungal infection and can also be observed in other intracranial conditions.

Choice C:

Decreased glucose levels in the CSF are a characteristic finding in bacterial or fungal meningitis. The invading bacteria or fungi consume glucose, leading to lower levels in the CSF compared to normal blood glucose levels. This finding helps differentiate bacterial or fungal meningitis from viral meningitis, where glucose levels are usually normal.

Choice D:

Elevated protein levels in the CSF can be seen in various conditions, including meningitis. While it indicates increased inflammation and breakdown of cells, it is not specific to bacterial or fungal infection and can be present in viral or other forms of meningitis.

Question 12:

A client with suspected meningitis presents with pink-colored cerebrospinal fluid during a lumbar puncture. What does this finding indicate?

A. Normal CSF. B. Blood contamination. C. Bacterial infection. D. Dehydration.

Answer and Explanation

Choice A:

If the cerebrospinal fluid (CSF) were normal, it would have clear and colorless appearance. Pink-colored CSF indicates the presence of an abnormality, ruling out the normal CSF as an option.

Choice B:

The pink color of the CSF suggests blood contamination, which can occur during the lumbar puncture procedure. The presence of blood can alter the CSF composition and lead to false interpretations of laboratory results.

Choice C:

Bacterial infection may present with cloudy or purulent CSF, but it is not specifically associated with pink-colored CSF. Other signs, such as elevated white blood cell count and elevated protein levels, would be more indicative of a bacterial infection.

Choice D:

Dehydration does not typically cause pink-colored CSF. Dehydration may lead to a higher concentration of solutes in the CSF, but it does not affect its coloration.

Question 13:

A client is diagnosed with viral meningitis. What is the appropriate treatment for this client?

A. Intravenous antibiotics. B. Antifungal drugs. C. Supportive care. D. Prophylactic corticosteroids.

Answer and Explanation

Choice A:

Intravenous antibiotics are used to treat bacterial meningitis, not viral meningitis. Viral meningitis is caused by viruses and does not respond to antibiotics.

Choice B:

Antifungal drugs are used to treat fungal meningitis, not viral meningitis. Viral meningitis is caused by viruses, not fungi.

Choice C:

Supportive care is the appropriate treatment for viral meningitis. Since viral meningitis is usually self-limiting and does not respond to specific antiviral medications, treatment focuses on managing symptoms and providing supportive measures to help the client recover.

Choice D:

Prophylactic corticosteroids may be used in certain cases of bacterial meningitis to reduce inflammation and prevent complications, but they are not indicated for the treatment of viral meningitis.

Question 14:

Which of the following nursing interventions is essential for preventing the spread of meningitis?

A. Administering antipyretics. B. Elevating the head of the bed. C. Providing comfort measures. D. Practicing good hygiene habits.

Answer and Explanation

Choice A:

Administering antipyretics helps to reduce fever, but it does not specifically prevent the spread of meningitis. It addresses a symptom but does not target the transmission of the disease.

Choice B:

Elevating the head of the bed is beneficial for clients with increased intracranial pressure, not for preventing the spread of meningitis.

Choice C:

Providing comfort measures can improve the client's well-being, but it does not directly address the prevention of meningitis transmission.

Choice D:

Practicing good hygiene habits, such as regular handwashing, can help prevent the spread of meningitis. Since meningitis can be transmitted through respiratory secretions, practicing good hygiene is essential in reducing the risk of infection transmission.

Question 15:

A client is planning to travel to a high-risk area for meningitis. What is the recommended preventive measure for this situation?

A. Taking prophylactic antibiotics. B. Getting vaccinated against mumps. C. Practicing good hand hygiene. D. Avoiding close contact with people with respiratory infections.

Answer and Explanation

Choice A:

The recommended preventive measure for a client planning to travel to a high-risk area for meningitis is to take prophylactic antibiotics. Meningitis is an inflammation of the meninges, the membranes covering the brain and spinal cord, and it can be caused by various pathogens, including bacteria. Travel to high-risk areas may increase the risk of exposure to meningitis-causing bacteria. Prophylactic antibiotics are given to individuals at high risk of contracting bacterial meningitis to prevent infection or reduce the severity if exposed. Commonly used antibiotics for prophylaxis include ciprofloxacin, rifampin, and others, depending on the specific high-risk area and its predominant pathogens.

Choice B:

Getting vaccinated against mumps is not the recommended preventive measure for meningitis caused by other pathogens. Mumps is a viral infection caused by the mumps virus, and while it can cause complications, it is not a common cause of meningitis. The appropriate preventive measure for mumps is vaccination with the measles, mumps, and rubella (MMR) vaccine.

Choice C:

Practicing good hand hygiene is essential for preventing the spread of infections in general, but it is not specifically targeted at preventing meningitis. Meningitis is usually transmitted through respiratory droplets or direct contact with infected individuals. While hand hygiene can help reduce the risk of contracting various infections, it is not the primary preventive measure for meningitis.

Choice D:

Avoiding close contact with people with respiratory infections is a good practice to reduce the risk of various respiratory infections, including those that can cause meningitis. However, it is not the recommended specific preventive measure for a client planning to travel to a high-risk area for meningitis. Prophylactic antibiotics are the more appropriate choice in this situation to directly target potential meningitis-causing bacteria.

(Select all that apply): A nurse is caring for a client with fungal meningitis. Which antifungal drugs may be used to treat this condition? (Select all that apply)

A. Amphotericin B. B. Fluconazole. C. Albendazole. D. Ivermectin. E. Voriconazole.

Answer and Explanation

Choice A:

Amphotericin B is an antifungal drug that may be used to treat fungal meningitis. It is effective against a wide range of fungal pathogens and is often considered the drug of choice for severe systemic fungal infections, including fungal meningitis.

Choice B:

Fluconazole is another antifungal drug used to treat fungal meningitis. It is effective against certain types of fungi, especially Candida species, which are known to cause fungal meningitis in some cases.

Choice C:

Albendazole is an antiparasitic drug and is not used to treat fungal meningitis. It is primarily indicated for the treatment of parasitic infections, such as certain types of worms.

Choice D:

Ivermectin is another antiparasitic drug and is not used in the treatment of fungal meningitis. It is commonly used to treat various parasitic infections but has no activity against fungal pathogens.

Choice E:

Voriconazole is a broad-spectrum antifungal medication that is also used to treat fungal meningitis. It is particularly effective against Aspergillus species, which can cause invasive fungal infections, including meningitis.

Question 17:

A nurse is assessing a group of patients in a temperate region during summer. Which type of meningitis is more likely to be prevalent in this population?

A. Viral meningitis. B. Bacterial meningitis. C. Fungal meningitis. D. Parasitic meningitis.

Answer and Explanation

Choice A:

In a temperate region during summer, viral meningitis is more likely to be prevalent in the population. Viral meningitis is most commonly caused by enteroviruses, and these infections tend to be more common in the summer and early fall. Enteroviruses thrive in warm and humid conditions, contributing to the seasonal variation in viral meningitis cases.

Choice B:

Bacterial meningitis can occur throughout the year and is not specifically associated with summer or temperate regions. Bacterial meningitis can result from various bacterial pathogens and is usually a more severe and life-threatening form of meningitis compared to viral meningitis.

Choice C:

Fungal meningitis is not typically associated with temperate regions during the summer. Fungal meningitis is more commonly seen in individuals with compromised immune systems or in specific geographic regions with a higher prevalence of fungal infections.

Choice D:

Parasitic meningitis is not prevalent in temperate regions during the summer. Parasitic meningitis is rare and is usually associated with specific parasitic infections, such as those caused by Naegleria fowleri or Angiostrongylus cantonensis, which are typically found in tropical or subtropical regions.

Question 18:

A client is planning a trip to a tropical region in winter. Which type of meningitis is more common in such regions during this season?

A. Viral meningitis. B. Bacterial meningitis. C. Fungal meningitis. D. Parasitic meningitis.

Answer and Explanation

Choice A:

Viral meningitis is caused by viral infections and is more commonly seen in the summer and fall months rather than in tropical regions during winter.

Choice B:

Bacterial meningitis is more common in tropical regions during the winter season. It is caused by bacterial infections and can be severe and life-threatening if not promptly treated. The colder weather in the winter may increase the transmission of bacteria responsible for causing meningitis.

Choice C:

Fungal meningitis is not specifically associated with any particular season or region. It can occur in individuals with weakened immune systems, but it is not more common in tropical regions during winter.

Choice D:

Parasitic meningitis is primarily caused by parasites and is not typically associated with any specific season or region. It is a rare form of meningitis and is not more prevalent in tropical regions during winter.

Question 19:

A nurse is providing education on meningococcal meningitis prevention. Which statement by the nurse is accurate?

A. "This type of meningitis is mainly seen in infants.” B. "It occurs primarily in regions with contaminated water.” C. "It can cause death within hours if left untreated.” D. "Fungal meningitis has a higher mortality rate than this type.”

Answer and Explanation

Choice A:

Meningococcal meningitis is not mainly seen in infants. It can affect individuals of all ages, but infants and young children are more susceptible to certain types of bacterial meningitis, such as Haemophilus influenzae type b.

Choice B:

Meningococcal meningitis is primarily transmitted through respiratory droplets, close contact with an infected person, or exposure to contaminated respiratory or throat secretions. It is not primarily linked to regions with contaminated water.

Choice C:

Meningococcal meningitis can progress rapidly and cause death within hours if left untreated. Therefore, early recognition and prompt medical treatment are essential to improve outcomes.

Choice D:

The statement comparing meningococcal meningitis with fungal meningitis' mortality rate is not accurate. While meningococcal meningitis can be severe, fungal meningitis is generally associated with a higher mortality rate, especially in individuals with weakened immune systems.

Question 21:

A nurse is caring for a patient with suspected meningitis. Which diagnostic procedure should the nurse expect to be performed to confirm the diagnosis?

A. Blood culture. B. Urinalysis. C. Lumbar puncture and CSF analysis. D. Chest X-ray.

Answer and Explanation

Choice A:

Blood culture is not the appropriate diagnostic procedure for confirming meningitis. While blood cultures can identify bacteria or other pathogens in the bloodstream, it may not directly confirm meningitis, as the infection is primarily located in the cerebrospinal fluid (CSF)

Choice B:

Urinalysis is not the appropriate diagnostic procedure for confirming meningitis. Urinalysis helps in detecting urinary tract infections or kidney-related issues, but it does not provide relevant information about meningitis.

Choice C:

Lumbar puncture and CSF analysis are essential in diagnosing meningitis. This procedure involves inserting a needle into the spinal canal to collect a sample of CSF, which is then analyzed for signs of infection, such as elevated white blood cell count, increased protein levels, and the presence of bacteria or viruses. It helps differentiate between bacterial, viral, or fungal causes and guides appropriate treatment.

Choice D:

A chest X-ray is not directly related to diagnosing meningitis. It is used to evaluate lung and heart conditions, making it irrelevant in confirming meningitis.

Question 22:

A patient with weakened immunity presents with chronic meningitis. Which type of meningitis is more likely in this case?

A. Viral meningitis. B. Bacterial meningitis. C. Fungal meningitis. D. Parasitic meningitis.

Answer and Explanation

Choice A:

Viral meningitis is less likely in this case because the patient has weakened immunity, suggesting a chronic and severe condition. Viral meningitis is often self-limiting and less severe in immunocompetent individuals.

Choice B:

Bacterial meningitis is less likely in this case as well, as chronic meningitis usually has a slower onset, and bacterial meningitis tends to have a more acute and rapidly progressive course.

Choice C:

Fungal meningitis is more likely in a patient with weakened immunity, as certain fungal pathogens, such as Cryptococcus and Histoplasma, can cause chronic and persistent meningitis in immunocompromised individuals.

Choice D:

Parasitic meningitis is not a common form of meningitis and is usually associated with specific parasitic infections, which are less likely to occur in immunocompromised patients.

Question 23:

Which of the following statements about meningitis prevention is accurate?

A. All types of meningitis can be prevented by vaccination. B. Meningitis can only be prevented through prophylaxis measures. C. Infection control measures are not effective in preventing meningitis outbreaks. D. Hygiene practices play a significant role in preventing meningitis transmission.

Answer and Explanation

Choice A:

All types of meningitis cannot be prevented by vaccination. While vaccinations are available for certain types of bacterial and viral meningitis, they do not cover all possible pathogens that can cause the disease.

Choice B:

Meningitis can be prevented through prophylaxis measures, but this statement is not entirely accurate. Prophylaxis may be given to close contacts of individuals with certain types of bacterial meningitis to prevent its spread, but it does not apply to all cases of meningitis.

Choice C:

Infection control measures are effective in preventing meningitis outbreaks. This statement is incorrect as infection control measures are crucial in controlling the spread of infections, but they cannot entirely prevent all cases of meningitis.

Choice D:

Hygiene practices, such as regular handwashing and proper respiratory etiquette, play a significant role in preventing meningitis transmission. By reducing the spread of respiratory and oral pathogens, the risk of meningitis can be lowered. However, it is important to note that not all forms of meningitis are entirely preventable through hygiene practices alone, which is why vaccination remains a critical preventive measure for specific types of meningitis.

Question 24:

A nurse is providing care to a pediatric patient diagnosed with Haemophilus influenzae type b meningitis. Which additional preventive measure should the nurse recommend?

A. Antibiotic therapy for the family members. B. Prophylaxis for the patient's close contacts. C. Hygiene education for school staff and students. D. Outbreak management protocols for the community. E. Vaccination against Neisseria meningitidis.

Answer and Explanation

Choice A:

Antibiotic therapy for the family members is not the most appropriate preventive measure for Haemophilus influenzae type b meningitis. While antibiotics are used to treat the infection, providing antibiotic therapy to family members does not prevent the spread of the bacteria to others.

Choice B:

Prophylaxis for the patient's close contacts is the recommended preventive measure for Haemophilus influenzae type b meningitis. Close contacts of a patient with this type of meningitis, such as household members and daycare contacts, are at an increased risk of contracting the disease. Administering prophylactic antibiotics to these individuals can help prevent the transmission of the bacteria and reduce the likelihood of developing the infection.

Choice C:

Hygiene education for school staff and students is not directly related to preventing the spread of Haemophilus influenzae type b meningitis. While hygiene education is essential for preventing the spread of infections in general, it is not specific to this particular type of meningitis.

Choice D:

Outbreak management protocols for the community may be necessary if there is an outbreak of Haemophilus influenzae type b meningitis. However, this choice does not address the immediate preventive measure needed for the diagnosed pediatric patient and their close contacts.

Choice E:

Vaccination against Neisseria meningitidis is not directly relevant to preventing Haemophilus influenzae type b meningitis. These are two different types of bacteria that cause different forms of meningitis, and vaccination against Neisseria meningitidis would not protect against Haemophilus influenzae type b meningitis.
