A nurse is caring for a client who has a new diagnosis of tuberculosis (TB). The client asks the nurse why she needs to take four different antituberculotic medications. Which of the following replies should the nurse make?
"The organism that causes TB becomes resistant to antituberculotic medications when you only take one medication."
Taking several antituberculotic medications will protect your liver from toxic effects."
"People who have a severe form of TB need several antituberculotic medications, but those who have less severe TB need just one medication."
"Adverse effects occur more often and are more severe when you take only one antituberculotic medication."
The Correct Answer is A
Choice A Reason:
"The organism that causes TB becomes resistant to antituberculotic medications when you only take one medication." This statement is appropriate.
Tuberculosis bacteria tend to develop resistance to single medications when used alone. Using multiple medications simultaneously helps prevent the bacteria from becoming resistant to any single drug. This strategy, known as combination therapy, is crucial in treating TB effectively and reducing the risk of drug resistance.
When TB bacteria are exposed to just one medication, they can mutate and become resistant to that specific drug. However, using a combination of medications helps ensure that if one medication fails to eliminate some bacteria due to resistance, the other drugs can still work against the resistant strains.
Preventing drug resistance is essential for successful TB treatment and to avoid the need for more complex and less effective medications if resistance develops.
Choice B Reason:
"Taking several antituberculotic medications will protect your liver from toxic effects." This statement is incorrect. While it's true that some antituberculotic medications can have hepatotoxic effects (adverse effects on the liver), the primary reason for using multiple medications in TB treatment isn't solely to protect the liver. The main goal of using multiple medications is to prevent the development of drug-resistant strains of TB bacteria. Protecting the liver is an important consideration in medication selection and monitoring but isn't the primary rationale for multiple medications.
Choice C Reason:
"People who have a severe form of TB need several antituberculotic medications, but those who have less severe TB need just one medication." This statement is incorrect. The severity of TB doesn't determine the number of medications required. The standard treatment approach for TB involves multiple medications, regardless of the severity. This approach aims to prevent the development of drug resistance, ensure effective treatment, and reduce the risk of treatment failure. Using a combination of medications is a fundamental strategy to combat TB effectively.
Choice D Reason:
"Adverse effects occur more often and are more severe when you take only one antituberculotic medication." This statement is incorrect. While it's true that adverse effects can occur with antituberculotic medications, the primary reason for using multiple medications isn't solely to reduce adverse effects. The main concern addressed by using multiple drugs is preventing the development of drug-resistant TB strains. Using a combination of medications reduces the likelihood of resistance developing and increases the effectiveness of treatment, rather than solely minimizing adverse effects.

Correct Answer is A
Explanation
Choice A Reason:
The client has a delayed response to verbal commands. This finding can indicate increased intracranial pressure. Changes in responsiveness, such as delayed responses to verbal commands or other stimuli, can be indicative of neurological impairment due to elevated pressure within the skull.
Choice B Reason:
The client has ecchymosis around the eyes. Ecchymosis around the eyes (raccoon eyes) can occur with certain head injuries, but it's not a direct sign of increased intracranial pressure. It's more commonly associated with basilar skull fractures rather than specifically reflecting increased pressure within the skull.
Choice C Reason:
The client is unable to remember details of the motor-vehicle crash. Memory impairment or amnesia regarding the event can occur due to head trauma, but it might not directly correlate with an increase in intracranial pressure. It's more related to the effects of the injury on memory function.
Choice D Reason:
The client reports ringing in the ears. Tinnitus or ringing in the ears might occur in some cases of head trauma but is not a direct indicator of increased intracranial pressure. It might result from the impact of the injury or other associated factors.
Correct Answer is A
Explanation
Choice A Reason;
"You should consume small, frequent meals each day." This statement is advisable for COPD management. Eating smaller, more frequent meals can help prevent bloating or feeling overly full, which might interfere with breathing due to increased pressure on the diaphragm.
Choice B Reason:
"You should decrease your caloric intake by 200 calories per day." While maintaining a healthy weight is important for COPD management, reducing caloric intake without specific guidance or assessment might not be suitable. It's crucial to consult with a healthcare provider or dietitian for individualized dietary recommendations.
Choice C Reason:
"You should increase your oxygen to 5 liters per minute if you have shortness of breath." Adjusting oxygen flow should be done based on a healthcare provider's prescribed guidelines. Self-adjustment of oxygen flow without medical advice can be risky and might not address the underlying cause of shortness of breath during a COPD exacerbation.
Choice D Reason:
"You should discontinue your prednisone when your symptoms improve." Prednisone or other corticosteroids are often prescribed during a COPD exacerbation to reduce inflammation in the airways. However, discontinuing corticosteroids abruptly without a healthcare provider's guidance can lead to a recurrence of symptoms or potential complications. It's important to follow the prescribed regimen and complete the course as directed.
