Test Bank Pharmacology and the Nursing Process

Correct Answer: A

Rationale: The correct answer is A because it demonstrates data validation in the nursing clinical decision-making process. The nurse assesses the time of the last dressing change and observes old and new drainage, which are relevant data points for wound care. This approach ensures that the decision to remove the dressing is based on accurate and validated information, leading to appropriate patient care. Choice B is incorrect because it relies on subjective information (increased pain and family request) rather than objective data validation. Choice C is incorrect as it involves a direct request for an order without sufficient data validation. Choice D is incorrect because elevating a leg cast based solely on a patient's report of decreased mobility does not involve thorough data validation related to the specific care needed for the patient's condition.

Correct Answer: C

Rationale: The correct answer is C: Restricting sodium. In hyperparathyroidism, there is an excess of parathyroid hormone leading to increased calcium levels. Sodium can worsen calcium excretion, exacerbating the condition. Restricting sodium can help reduce calcium loss. A: Restricting fluids is not necessary unless the client has kidney issues. B: Forcing fluids may not be beneficial and can lead to fluid overload. D: Restricting potassium is not typically necessary unless the client has kidney issues.

Correct Answer: D

Rationale: Correct Answer: D. Antagonize the action of K on the heart Rationale: 1. Calcium gluconate stabilizes cardiac cell membranes during hyperkalemia. 2. By antagonizing the effects of potassium on the heart, it helps prevent life-threatening cardiac arrhythmias. 3. It does not lower potassium levels immediately or prevent transient renal failure. 4. Administering calcium gluconate is specific to addressing the cardiac effects of hyperkalemia, not renal or overall potassium reduction.

Correct Answer: C

Rationale: The correct answer is C: Cough. Enalapril is an ACE inhibitor, and a common side effect is a dry, persistent cough due to the accumulation of bradykinin. This is a distinctive side effect of ACE inhibitors and should be reported to the healthcare provider. Acne (A), diarrhea (B), and heartburn (D) are not commonly associated with enalapril use and are less likely side effects.

Correct Answer: A

Rationale: The correct answer is A: It inhibits deoxyribonucleic acid (DNA) synthesis. Mitomycin is an alkylating agent that works by cross-linking DNA, preventing DNA synthesis and leading to cell death. This mechanism of action makes it effective against rapidly dividing cells like cancer cells. Choice B, inhibiting ribonucleic acid (RNA) synthesis, is incorrect as mitomycin primarily targets DNA synthesis. Choice C, being cell cycle-phase specific, is incorrect as mitomycin affects cells in all phases of the cell cycle. Choice D, inhibiting protein synthesis, is incorrect because mitomycin's primary mode of action is on DNA replication, not protein synthesis.
