Signs and symptoms

- The signs and symptoms of tetanus vary depending on the type, severity, and location of muscle involvement. -They usually appear within 3 to 21 days after exposure to C. tetani spores (incubation period), with an average of 8 days[.

- The most common type of tetanus is generalized tetanus (80% of cases), which affects all skeletal muscles[. The first symptom is usually trismus (lockjaw), which is difficulty opening the mouth due to spasms of the masseter muscles[. This is followed by risus sardonicus, which is a grimace or smile caused by spasms of the facial muscles[.

- Other symptoms of generalized tetanus include dysphagia (difficulty swallowing), opisthotonos (arching of the back), sardonic laughter (involuntary laughter), laryngeal spasm (difficulty breathing), tachycardia (rapid heart rate), hypertension (high blood pressure), diaphoresis (sweating), fever, and dysuria (difficulty urinating)[.

- The muscle spasms are triggered by stimuli such as noise, light, touch, or movement. They can last from seconds to minutes and can be very painful and exhausting. They can also lead to complications such as fractures, dislocations, rhabdomyolysis (muscle breakdown), respiratory failure, aspiration pneumonia, pulmonary embolism, and cardiac arrhythmias[.

- The mortality rate of generalized tetanus is 10% to 20%, with higher rates in neonates and elderly[.

- The second most common type of tetanus is localized tetanus (10% of cases), which affects only the muscles near the site of infection[. The symptoms are similar to those of generalized tetanus but milder and less widespread. The prognosis is better than that of generalized tetanus[.

- The rarest type of tetanus is cephalic tetanus (<1% of cases), which affects only the cranial nerves, especially the facial nerve[. The symptoms include facial paralysis, ptosis (drooping eyelid), diplopia (double vision), dysphagia, and dysarthria (slurred speech)[. Cephalic tetanus can progress to generalized tetanus or result in death due to respiratory failure[.

Questions on Signs and symptoms

Correct Answer is B

Explanation

Streptococcus pneumoniae is not responsible for tetanus. It is a bacterium commonly associated with respiratory infections, such as pneumonia.

Correct Answer is ["A","C","D"]

Explanation

Applying heat to affected areas is not appropriate for managing tetanus. Heat application can exacerbate muscle contractions and is not a recommended intervention for this condition.

Correct Answer is C

Explanation

The correct statement highlights that tetanus is more common in developing countries due to lower immunization rates. This is accurate since immunization plays a significant role in preventing tetanus, and lower vaccination rates in some regions contribute to higher disease incidence.

Correct Answer is A

Explanation

The statement "I've been experiencing some difficulty swallowing" should be monitored, but it doesn't need immediate intervention unless it worsens and compromises the airway.

Correct Answer is C

Explanation

<p>The statement &quot;Vector transmission of tetanus occurs primarily through mosquito bites&quot; is incorrect. Tetanus is not transmitted through mosquito bites. Mosquitoes are not carriers of C. tetani, and the infection does not spread through their bites.</p>

Correct Answer is B

Explanation

<p>Pneumonia is an infection that inflames the air sacs in the lungs, and it is caused by various pathogens, including bacteria, viruses, and fungi. It is not directly linked to wound contamination with soil and feces.</p>

Correct Answer is D

Explanation

No explanation

Correct Answer is B

Explanation

<p>Applying a cold compress to the wound can help reduce pain and swelling, but it does not prevent tetanus. The priority is to administer tetanus antitoxin to neutralize the neurotoxin if present.</p>

Risus sardonicus, a facial muscle spasm resulting in a sardonic grin-like expression, is a classic sign of tetanus and is caused by sustained contraction of facial muscles.

Using non-pharmacological methods for pain management is an essential aspect of caring for clients with tetanus. Pain relief measures, such as warm compresses and positioning, can help alleviate muscle spasms and discomfort.

Facial muscle paralysis and slurred speech are not characteristic of localized tetanus. These symptoms are more commonly seen in conditions affecting the cranial nerves or other neurological disorders.

The statement "Penicillin G has a broader spectrum of activity than metronidazole" is irrelevant to the client's tetanus treatment. While it is true that different antibiotics have different spectrums of activity, this information is not relevant to the client's current condition or treatment.

The statement "Diaphoresis (sweating)" is not directly associated with muscle spasms triggered by stimuli in tetanus. Diaphoresis may occur in response to fever or autonomic dysfunction but is not a primary concern related to the muscle spasms.

<p>The statement &quot;Neonatal tetanus, affecting infants born to non-immunized mothers&quot; is not the most common type of tetanus. Neonatal tetanus occurs in newborns born to inadequately immunized mothers and is also relatively rare compared to generalized tetanus in adults.</p>

<p>Using non-pharmacological methods for pain management may be helpful, but it is not the priority intervention for a client with generalized tetanus experiencing spasms triggered by stimuli. The priority is to administer TIG to counteract the effects of the tetanus toxin.</p>

<p>Stimulating the production of dopamine in the spinal cord is not a mechanism of action for benzodiazepines. This statement is inaccurate. Chickenpox/Shingles. .</p>
