Correct Answer: A

Rationale: The correct answer is A because understanding pain management involves considering non-pharmacological approaches, such as listening to music for relaxation and comfort. Choice B is incorrect as excessive sleep may not be an effective pain management strategy. Choice C is incorrect because pain medication may still be necessary even if pain levels are low. Choice D is not the best answer, as it simply states following the nurse's suggestions without demonstrating an understanding of personalized pain management techniques.

Correct Answer: C

Rationale: Corrected Rationale: Metabolic acidosis is a serious side effect of mafenide therapy that should be closely monitored. Mafenide can lead to metabolic acidosis due to its inhibition of carbonic anhydrase, resulting in the accumulation of carbonic acid. Curling ulcer (Choice A) is a stress-related mucosal lesion that occurs in the duodenum, primarily due to severe burns, not directly related to mafenide therapy. Renal shutdown (Choice B) is not a common side effect of mafenide therapy. Hemolysis of red blood cells (Choice D) is not a recognized side effect of mafenide cream application.

Correct Answer: A

Rationale: The correct answer is A: Temperature. A high fever is a significant indicator of infection or other serious conditions, making it the priority finding. Elevated temperature indicates an immediate concern for infection, which can quickly escalate and lead to severe complications if not addressed promptly. While heart rate, abdominal tenderness, and census overdue are important aspects to consider in the client's care, addressing the fever takes precedence due to its potential severity and implications for the client's health.

Correct Answer: C

Rationale: After a client experiences severe coughing following nasogastric tube feedings, it is crucial to verify proper tube placement. Checking the pH of fluid withdrawn from the tube helps confirm the tube's correct positioning. Option A is incorrect because further action is necessary to ensure the client's safety. Option B is inappropriate as it suggests stopping the feeding without assessing the tube's placement. Option D is incorrect as injecting air into the tube may lead to further complications if the tube is not positioned correctly.

Correct Answer: D

Rationale: When caring for an unconscious patient, it is crucial to prevent choking and aspiration. Suctioning the oral cavity helps in removing secretions and preventing potential harm. Moisten the mouth using lemon-glycerin sponges may not effectively clear secretions. Holding the patient's mouth open with gloved fingers can cause discomfort and potential harm. Using foam swabs to remove plaque may not address the immediate risk of aspiration.
