A nurse is reviewing a client's medication regimen. Which of the following medications places the client at increased risk for digoxin toxicity?

A. Calcium channel blockers

B. Potassium-sparing diuretics

C. Beta blockers

D. Loop diuretics

Correct Answer: D
Rationale: The correct answer is D, Loop diuretics. Loop diuretics can lead to hypokalemia, which increases the risk for digoxin toxicity. Loop diuretics cause potassium loss, and hypokalemia can potentiate the toxic effects of digoxin. Choices A, B, and C are incorrect because calcium channel blockers, potassium-sparing diuretics, and beta blockers do not directly increase the risk of digoxin toxicity.

A healthcare provider has just administered a wrong medication to a client. Which of the following actions should the provider take next?

• A. No action is needed
• B. Report error to the provider
• C. Complete an institutional incident report
• D. Inform the client that the wrong medication was given

Correct Answer: B
Rationale: In the scenario where a wrong medication has been administered, it is crucial for the healthcare provider to report the error to the provider. This action is essential to ensure that the provider is informed promptly, corrective measures are taken, and the client's well-being is safeguarded. Choice A is incorrect as taking no action could lead to serious consequences and compromise patient safety. Choice C, while important, should come after reporting the error to the provider. Choice D is not the immediate priority as the provider should first focus on addressing the error internally.

A nurse is caring for a client receiving theophylline for chronic obstructive pulmonary disease (COPD). Which of the following client findings indicates the need for immediate intervention?

• A. Productive cough
• B. Drowsiness
• C. Vomiting
• D. Polyuria

Correct Answer: D
Rationale: Polyuria is a sign of theophylline toxicity and requires immediate intervention. Theophylline toxicity can lead to serious complications, and polyuria is a concerning symptom that indicates the need for urgent medical attention. Productive cough, drowsiness, and vomiting are common side effects of theophylline but are not typically indicative of immediate life-threatening issues like polyuria in the context of theophylline toxicity.

Disulfiram is taken by a client daily for abstinence maintenance. What is an adverse effect of this therapy?

• A. Hepatotoxicity
• B. Wernicke's aphasia
• C. Suicidal ideations
• D. Diarrhea

Correct Answer: A
Rationale: The correct answer is A: Hepatotoxicity. Disulfiram is known to cause hepatotoxicity as a severe adverse effect. This occurs due to the inhibition of aldehyde dehydrogenase, leading to the accumulation of acetaldehyde when alcohol is consumed. Wernicke's aphasia (Choice B) is a language disorder unrelated to disulfiram therapy. Suicidal ideations (Choice C) may be associated with certain medications, but it is not a common adverse effect of disulfiram. Diarrhea (Choice D) is not a typical adverse effect of disulfiram.

A nurse is preparing to administer metoprolol to a client with hypertension. Which of the following should the nurse assess prior to administering this medication?

• A. Temperature
• B. Heart rate
• C. Respiratory rate
• D. Blood pressure

Correct Answer: D
Rationale: The correct answer is D: Blood pressure. Before administering metoprolol, a beta-blocker commonly used to treat hypertension, the nurse should assess the client's blood pressure. Metoprolol works by lowering blood pressure and reducing the workload on the heart. Assessing the blood pressure is crucial to ensure it is within the acceptable range to administer the medication safely. Choices A, B, and C (Temperature, Heart rate, Respiratory rate) are important assessments in general patient care but are not specifically required before administering metoprolol for hypertension.
