1. When caring for a client prescribed Digoxin, which of the following laboratory values should the nurse monitor to assess for potential toxicity?

Correct answer: B

Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin. Sodium, magnesium, and calcium levels are not directly associated with Digoxin toxicity; hence, they are not the primary focus for monitoring in this case.

2. A client has a new prescription for Ranitidine. Which of the following instructions should the nurse include?

Correct answer: C

Rationale: The correct instruction for a client prescribed Ranitidine is to take the medication at bedtime. Ranitidine is best taken at night to reduce nighttime stomach acid production, providing optimal relief for conditions like gastroesophageal reflux disease (GERD) and ulcers.

3. When educating a client with a new prescription for Amlodipine, which instruction should the nurse provide?

Correct answer: B

Rationale: The correct answer is to advise the client to avoid driving until they understand the medication's effects. Amlodipine can cause dizziness, making it unsafe to drive until the client knows how the medication affects them. This instruction promotes client safety and prevents potential accidents due to medication side effects.

4. A client is taking Desmopressin for Diabetes Insipidus. For which of the following adverse effects should the nurse monitor?

Correct answer: D

Rationale: Headache is an adverse effect that the nurse should monitor for in a client taking Desmopressin for Diabetes Insipidus. It can be an early sign of water intoxication, which is a potential complication of desmopressin therapy due to excessive water retention in the body.

5. What is the action of Nitroglycerin?

Correct answer: D

Rationale: Nitroglycerin acts by dilating the coronary arteries, leading to increased blood flow and oxygen supply to the heart. This helps in relieving angina symptoms by reducing the heart's workload and improving blood supply to the myocardium. Choices A, B, and C are incorrect because Nitroglycerin's primary action is not related to dilating bronchi, reducing blood glucose, or reducing nausea.
