Correct Answer: A

Rationale: The correct answer is to administer epinephrine as the first intervention for a patient experiencing anaphylactic shock. Epinephrine is crucial in reversing the allergic reaction and restoring cardiovascular stability. Corticosteroids (Choice B) are not the first-line treatment for anaphylactic shock but may be used as an adjunct therapy. Antihistamines (Choice C) can help relieve itching and hives but are not as effective as epinephrine in treating the systemic effects of anaphylaxis. Oxygen (Choice D) may be necessary to support breathing in severe cases of anaphylaxis, but administering epinephrine takes precedence in the management of anaphylactic shock.

Correct Answer: A

Rationale: The correct method of administering insulin to a patient with diabetes is to administer it subcutaneously. Insulin is typically injected into the fatty tissue just below the skin, allowing for a slow and consistent absorption into the bloodstream. Administering insulin intramuscularly (Choice B) is not recommended as it can lead to unpredictable absorption rates and potential complications. Administering insulin intravenously (Choice C) is only done in specific medical settings and not for routine diabetes management. Administering insulin orally (Choice D) is ineffective as the stomach acid would break down the insulin before it can be absorbed.

Correct Answer: C

Rationale: The correct answer is to monitor potassium levels when a patient is receiving furosemide because furosemide can cause potassium depletion. It is essential to monitor potassium levels to prevent complications such as hypokalemia. While monitoring urine output is important in assessing kidney function, and monitoring blood pressure and serum creatinine are relevant in certain situations, the priority when administering furosemide is to monitor potassium levels due to the medication's potential to deplete potassium.

Correct Answer: C

Rationale: The correct answer is to encourage weight-bearing exercises to prevent bone loss in clients with osteoporosis. Weight-bearing exercises help to strengthen bones and reduce the risk of fractures. Increasing calcium intake (Choice A) is important for bone health but is not the priority intervention for preventing bone loss in osteoporosis. Applying heat to affected joints (Choice B) may help with stiffness but does not address the underlying bone loss in osteoporosis. Limiting fluid intake (Choice D) is not relevant to managing osteoporosis and preventing bone loss.

Correct Answer: D

Rationale: The correct answer is D because sitting quietly for 5 minutes before measuring blood pressure ensures an accurate reading and helps monitor hypertension. Choice A is incorrect as medications for hypertension should be taken as prescribed, not based on symptoms like dizziness. Choice B is not ideal as blood pressure should be checked more frequently, preferably daily. Choice C is incorrect as stopping medication abruptly once blood pressure is normal can lead to rebound hypertension.
