The nurse should monitor the client for clinical manifestations of digoxin toxicity if the laboratory report reflects a serum:
glucose of 110 mg/dL.
potassium of 3.0 mEq/L.
calcium of 9.0 mg/dL.
sodium of 133 mEq/L.
The Correct Answer is B
Choice A reason: Glucose of 110 mg/dL is not a finding that indicates digoxin toxicity. It is a normal blood glucose level for a fasting or non-fasting client.
Choice B reason: Potassium of 3.0 mEq/L is a finding that indicates digoxin toxicity. It is a low serum potassium level, which increases the risk of digoxin toxicity by enhancing the binding of digoxin to cardiac cells. The nurse should monitor the client for signs and symptoms of digoxin toxicity, such as nausea, vomiting, anorexia, fatigue, confusion, visual disturbances, and cardiac arrhythmias.
Choice C reason: Calcium of 9.0 mg/dL is not a finding that indicates digoxin toxicity. It is a normal serum calcium level for an adult client.
Choice D reason: Sodium of 133 mEq/L is not a finding that indicates digoxin toxicity. It is a slightly low serum sodium level, which may indicate hyponatremia, but not digoxin toxicity.

Correct Answer is B
Explanation
Choice A reason: This is incorrect. Walking directly in front of the client may block their view and increase their risk of falling. The nurse should walk to the side and slightly behind the client to provide support and guidance³.
Choice B reason: This is correct. Walking along the affected left side allows the nurse to assist the client with balance, weight shifting, and foot clearance. The nurse should also encourage the client to use the handrail on their strong side³.
Choice C reason: This is incorrect. Walking directly behind the client may not allow the nurse to see the client's gait pattern or intervene quickly if the client loses balance. The nurse should walk to the side and slightly behind the client to monitor and assist them³.
Choice D reason: This is incorrect. Walking along the unaffected right side may not provide adequate support or protection for the client's affected side. The nurse should walk along the affected left side to help the client with their hemiplegic gait³.
Correct Answer is A
Explanation
Choice A reason: Exertional dyspnea is a common symptom of unstable angina, which is caused by reduced blood flow to the heart muscle. Carvedilol is a beta-blocker that reduces the workload of the heart and improves its oxygen supply. Therefore, resolving exertional dyspnea indicates that the medication has been effective.
Choice B reason: A heart rate of 50 beats/minute is not a desired outcome of carvedilol therapy. It may indicate that the dose is too high or that the client has a conduction problem. A normal resting heart rate for adults is between 60 and 100 beats/minute.
Choice C reason: A regular heart rhythm is not a specific indicator of carvedilol effectiveness. Carvedilol can prevent or treat some arrhythmias, but it is not the primary goal of therapy for unstable angina. A regular heart rhythm may also be influenced by other factors such as electrolytes, hydration, and stress.
Choice D reason: A blood pressure of 120/90 is not a sign of carvedilol effectiveness. Carvedilol can lower blood pressure, but it is not the main purpose of treatment for unstable angina. A blood pressure of 120/90 is considered prehypertension, which may increase the risk of cardiovascular complications.
