A patient is being treated for a respiratory infection. The nurse notes that the patient's pulse is elevateWhich of the following interventions should the nurse prioritize?

Correct Answer: A

Rationale: The correct answer is A: Administering antipyretics as prescribed. Elevated pulse can indicate fever, which may be a sign of infection. Administering antipyretics helps reduce fever, which can help lower the pulse rate. This intervention addresses the underlying cause of the elevated pulse. Increasing fluid intake (B) is important but does not directly address the elevated pulse. Encouraging rest (C) is beneficial but may not directly impact the pulse rate. Monitoring respiratory rate (D) is important but addressing the fever with antipyretics is the priority in this case.

Correct Answer: B

Rationale: The correct answer is B. The small intestine is where the majority of digestion and absorption occur due to its large surface area for nutrient absorption. This is facilitated by villi and microvilli. Choice A is incorrect as the small intestine is lined with villi and microvilli, not smooth muscle. Choice C is incorrect because bile is produced in the liver and stored in the gallbladder. Choice D is incorrect as carbohydrate digestion primarily occurs in the mouth and small intestine.

Correct Answer: B

Rationale: The correct answer is B: amylase. Amylase is responsible for breaking down carbohydrates into smaller sugar molecules in the digestive system. It is produced in the saliva and pancreas. Lipase (A) digests fats, pepsin (C) digests proteins, and trypsin (D) also digests proteins, not carbohydrates. Therefore, amylase is the correct enzyme for carbohydrate digestion.

Correct Answer: D

Rationale: Saliva does not contain platelets because platelets are components of blood responsible for blood clotting, not found in saliva. Saliva does contain ABO blood group antigens, lysozymes for antibacterial activity, and immunoglobulins for immune function. Platelets are not a normal component of saliva, making option D the correct answer.

Correct Answer: A

Rationale: After a cholecystectomy, the gallbladder is removed, affecting bile storage and release. The liver still produces bile, but it is not stored in the gallbladder for efficient release when needed. This results in inadequate bile availability to emulsify fats, leading to difficulty digesting fat-rich foods. Choices B and C are incorrect as they do not directly address the issue of insufficient bile production. Choice D is incorrect as bile concentration is not the primary concern post-cholecystectomy.
