Correct Answer: B

Rationale: The correct answer is B because removing anti-embolism stockings for short periods prevents skin breakdown while ensuring that the stockings remain effective in promoting circulation. Choice A is incorrect because massaging lower extremities daily does not prevent DVT; instead, it may dislodge a clot. Choice C is incorrect as limiting intake of foods high in calcium does not prevent renal calculi; rather, it may help reduce the risk of kidney stones. Choice D is incorrect because encouraging the client to lie supine does not prevent constipation; instead, encouraging mobility and adequate fluid intake can help prevent constipation in immobile clients.

Correct Answer: C

Rationale: During triage after a mass casualty event, the client showing signs of hypovolemic shock should be prioritized. Hypovolemic shock is a life-threatening condition that requires immediate attention to restore circulation and prevent death. While clients with head trauma, burns, and fractures also need urgent care, hypovolemic shock poses an immediate threat to life and must be addressed first to stabilize the client's condition.

Correct Answer: A

Rationale: Tingling in the fingers and around the mouth is a sign of hypocalcemia, which can occur after thyroid surgery due to accidental damage to the parathyroid glands. Hypocalcemia is common after thyroidectomy due to potential parathyroid damage. Calcium gluconate is the appropriate intervention to treat hypocalcemia. Providing a high-protein diet or administering levothyroxine are not indicated for hypocalcemia. Applying a warm compress to the client's neck would not address the underlying issue of hypocalcemia.

Correct Answer: A

Rationale: A GFR of 14 mL/min indicates significant kidney damage and a severe decrease in kidney function. This level of GFR typically indicates the need for hemodialysis to help the kidneys perform their function adequately. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and managing chronic kidney disease but do not specifically indicate the need for hemodialysis. Therefore, choices B, C, and D are incorrect.

Correct Answer: D

Rationale: The client with slurred speech, disorientation, and a headache may be experiencing a stroke, a life-threatening condition that requires immediate attention. Identifying and managing a stroke promptly can reduce the risk of long-term disability or complications. The other options, although important, do not present immediate life-threatening conditions that require urgent intervention. A dislocated shoulder, severe joint pain in sickle cell disease, confusion with fever and foul-smelling urine, while concerning, can be addressed after attending to the client with potential stroke symptoms.
