Correct Answer: A

Rationale: The correct answer is A: Administer antiemetics. Antiemetics help alleviate nausea and vomiting by blocking neurotransmitters in the brain. This intervention directly targets the symptoms and provides relief for the client. Administering fluids (B) may help with hydration but does not address the root cause. Administering analgesics (C) is for pain relief, not for nausea and vomiting. Monitoring electrolytes (D) is important but does not directly treat the symptoms. Therefore, administering antiemetics is the most appropriate intervention for severe nausea and vomiting.

Correct Answer: C

Rationale: The correct answer is C. Stopping insulin once blood glucose is normal is incorrect as insulin is crucial for managing diabetes even when blood glucose levels are within the target range. Insulin helps regulate blood sugar levels consistently, and stopping it abruptly can lead to hyperglycemia. Choices A, B, and D are correct statements indicating good diabetes management practices. Monitoring blood glucose levels, exercising regularly, and following a balanced diet are essential for controlling blood sugar levels and overall health.

Correct Answer: A

Rationale: The correct answer is A because tolerance is a physiological phenomenon where the body adapts to a drug, requiring higher doses for the same effect. This is a common occurrence with opioids in chronic pain management. Choice B is incorrect as it refers to drug-seeking behavior, not tolerance. Choice C is incorrect because addiction and physical dependence are different concepts. Choice D is incorrect as it relates to a specific scenario of substance abuse alongside chronic pain, not the mechanism behind the need for increased opioid doses in chronic pain management.

Correct Answer: D

Rationale: The correct answer is D: Lupus. Lupus can affect the kidneys, leading to renal impairment. Renal impairment can decrease the body's ability to excrete ammonia, resulting in elevated levels. Renal failure (choice A) can also lead to elevated ammonia levels, but lupus specifically contributes to renal issues. Cirrhosis (choice B) primarily affects the liver, not kidneys. Psoriasis (choice C) is a skin condition and does not directly impact ammonia levels.

Correct Answer: A

Rationale: The correct answer is A: Encouraging early ambulation to prevent deep vein thrombosis. Early ambulation helps prevent blood clot formation in the legs, reducing the risk of deep vein thrombosis post-surgery. It also promotes circulation and aids in preventing complications like pneumonia. Administering pain medication (B) is important, but preventing complications should take priority. Providing wound care (C) is essential but not the top priority. Encouraging a high-protein diet (D) is beneficial for healing, but immediate post-operative mobility is crucial for preventing complications.
