Correct Answer: C

Rationale: Ataxia and incoordination are signs of phenytoin toxicity rather than adverse reactions to rifampin or isoniazid. These symptoms indicate that the client is experiencing an adverse effect of phenytoin, requiring a dose adjustment. Choice A is incorrect because rifampin is not typically associated with ataxia and incoordination. Choice B is incorrect as the development of ataxia and incoordination does not necessarily mean the seizure disorder is no longer under control. Choice D is incorrect as the symptoms are more indicative of phenytoin toxicity rather than adverse effects of combination antimicrobial therapy.

Correct Answer: B

Rationale: The correct instruction the nurse should include is to 'Rest as needed throughout the day.' Fatigue is a common symptom of multiple sclerosis (MS), and adequate rest is essential to manage it effectively. Resting as needed helps conserve energy and prevent fatigue from worsening. Choices A, C, and D are incorrect. 'Exercise to the point of exhaustion' is not recommended as it can lead to increased fatigue. 'Avoiding physical activity' entirely is not advisable as appropriate exercise can help maintain strength and energy levels. 'Exercising only once per week' may not be sufficient to combat fatigue and maintain overall well-being in clients with MS.

Correct Answer: B

Rationale: The correct answer is B. Applying diaper cream during each diaper change is important to prevent skin breakdown in infants with rotavirus. Rotavirus can cause diarrhea, which can lead to skin irritation. Avoiding feeding the baby for 12 hours (choice A) can lead to dehydration and is not appropriate. Giving water between feedings (choice C) can further contribute to dehydration. Applying warm compresses (choice D) may provide comfort but does not address the specific issue of preventing skin breakdown associated with rotavirus.

Correct Answer: D

Rationale: The correct answer is to apply ice to the affected knee for 24-48 hours. Applying ice helps to reduce inflammation and pain after knee surgery, promoting healing. Choice A is incorrect because heat is not recommended postoperatively, as it can increase swelling. Choice B is incorrect because pillows should be placed under the knee to keep it elevated. Choice C is incorrect because early mobilization is essential for preventing complications such as blood clots.

Correct Answer: C

Rationale: The correct answer is C because avoiding solid foods after bariatric surgery is crucial to prevent complications and promote healing. Choice A is incorrect as carbonated beverages can cause discomfort and should be avoided. Choice B is incorrect as large meals are not suitable after bariatric surgery. Choice D is incorrect as taking small sips of liquids is encouraged to prevent dehydration and promote recovery.
