A nurse is caring for a client who has heart failure and is prescribed furosemide. Which of the following outcomes indicates that the medication is effective?

Correct Answer: D

Rationale: The correct answer is D. Increased urinary output is the desired outcome when administering furosemide to a client with heart failure. Furosemide is a diuretic that promotes the excretion of excess fluids from the body, which helps in reducing fluid overload, a common symptom of heart failure. Choices A, B, and C are not directly related to the action of furosemide in treating heart failure. Visual acuity improvement, decreased respiratory rate, and rapid weight loss are not typical indicators of furosemide effectiveness in managing heart failure.

Correct Answer: C

Rationale: The correct answer is monitoring the respiratory rate. Morphine can depress respiratory function, leading to respiratory depression or arrest. Therefore, closely monitoring the client's respiratory rate is crucial to detect any signs of respiratory distress. While blood pressure, heart rate, and temperature are important assessments, in this scenario, respiratory rate takes precedence due to the potential respiratory complications associated with morphine administration.

Correct Answer: B

Rationale: The correct answer is B: Decreased anginal pain. Verapamil is a calcium channel blocker used to relieve angina by reducing myocardial oxygen demand. Monitoring for decreased anginal pain is essential as it indicates a therapeutic response to the medication. Choices A, C, and D are incorrect as verapamil's primary goal in this context is not to decrease blood pressure, heart rate, or anxiety.

Correct Answer: C

Rationale: The correct answer is to instruct the client to 'Move slowly when standing up.' Codeine can cause orthostatic hypotension, a drop in blood pressure when changing positions, leading to dizziness or fainting. By advising the client to move slowly when standing up, the nurse helps prevent falls or injuries due to sudden drops in blood pressure. Choices A, B, and D are important instructions as well but not the priority when considering the risk of orthostatic hypotension associated with codeine.

Correct Answer: B

Rationale: The correct answer is to apply a new patch every morning. Nitroglycerin patches should be applied in the morning and removed at bedtime to provide a 14-hour nitrate-free interval, preventing tolerance development. Choice A is incorrect because applying a patch every 12 hours may lead to tolerance. Choice C is incorrect because nitroglycerin patches are used prophylactically, not just when symptoms appear. Choice D is incorrect because rotating the application site weekly is not necessary; the same site can be used as long as there is no skin irritation.
