1. The client with a history of heart failure is receiving digoxin (Lanoxin). Which electrolyte imbalance increases the risk of digoxin toxicity?

• A. Hypernatremia
• B. Hypercalcemia
• C. Hypokalemia
• D. Hypomagnesemia

Correct answer: C

Rationale: Hypokalemia increases the risk of digoxin toxicity as low potassium levels enhance the effects of digoxin on the heart, leading to toxicity and potential adverse effects. Hypernatremia (Choice A) is not directly associated with an increased risk of digoxin toxicity. Hypercalcemia (Choice B) does not increase the risk of digoxin toxicity. Hypomagnesemia (Choice D) can contribute to digoxin toxicity, but hypokalemia has a more significant impact on increasing the risk.

2. A client has just completed an information session about measures to minimize the progression of coronary artery disease (CAD). Which statement indicates an initial understanding of lifestyle alterations?

• A. I should take daily medication for life.
• B. I should eat a diet that is low in fat and cholesterol.
• C. I should continue to smoke to keep the metabolic rate high.
• D. I should begin to exercise if the diet is not sufficient to achieve weight loss.

Correct answer: B

Rationale: Choosing a diet that is low in fat and cholesterol is crucial for managing and preventing the progression of coronary artery disease (CAD). This dietary change can help reduce the risk of further complications associated with CAD, such as plaque buildup in the arteries. It is a fundamental lifestyle alteration that can positively impact the client's heart health. Option A is incorrect as relying solely on medication without lifestyle changes may not address the root cause of CAD. Option C is incorrect as smoking is harmful and worsens CAD. Option D is incorrect because exercise is a crucial part of a healthy lifestyle, but dietary changes should come first in managing CAD.

3. The client with a history of angina pectoris is being discharged after coronary artery bypass graft (CABG) surgery. Which statement by the client indicates a need for further teaching?

• A. I will avoid lifting heavy objects for at least 6 weeks.
• B. I will call the doctor if I develop a fever or drainage from my incisions.
• C. I will take my pain medication before doing any activities that might cause discomfort.
• D. I can resume my normal activities, including driving, as soon as I feel like it.

Correct answer: D

Rationale: The correct answer is D because after CABG surgery, patients need to follow specific guidelines for resuming activities, and driving is typically restricted for a certain period to ensure safety and proper recovery. Resuming normal activities too soon, including driving, can pose risks to the client's health and safety. It is essential to emphasize to the client the importance of following the healthcare provider's recommendations regarding activity restrictions post-surgery to prevent complications and promote optimal recovery. Choices A, B, and C are correct statements that align with post-CABG discharge instructions, emphasizing the importance of avoiding heavy lifting, monitoring for signs of infection, and managing pain effectively.

4. The healthcare provider notes this rhythm on the client's cardiac monitor. The healthcare provider next reports that the client is experiencing which heart rhythm?

• A. Normal sinus
• B. Atrial fibrillation
• C. Sinus bradycardia
• D. Ventricular fibrillation

Correct answer: B

Rationale: The correct answer is B, Atrial fibrillation. Atrial fibrillation is characterized by an irregular and often rapid heart rate, which can lead to poor blood flow due to ineffective contractions of the atria. Sinus bradycardia (Choice C) is a regular but slow heart rhythm originating from the sinus node. Normal sinus rhythm (Choice A) refers to a regular heartbeat originating from the sinus node. Ventricular fibrillation (Choice D) is a life-threatening arrhythmia characterized by rapid, uncoordinated contractions of the ventricles.

5. A client has a new prescription for docusate sodium. Which of the following instructions should be included in the discharge teaching?

• A. Take the medication with a full glass of water.
• B. Take the medication at bedtime.
• C. Take the medication on an empty stomach.
• D. Avoid taking the medication with antacids.

Correct answer: A

Rationale: Corrected Rationale: When taking docusate sodium, it is important to take the medication with a full glass of water to help ensure its proper effectiveness. This helps prevent the stool from hardening and makes it easier to pass, especially for individuals experiencing constipation. Choice B is incorrect because there is no specific instruction to take docusate sodium at bedtime. Choice C is incorrect because docusate sodium does not need to be taken on an empty stomach. Choice D is incorrect because there is no need to avoid taking docusate sodium with antacids.
