1. The LPN/LVN is assisting in caring for a client in the telemetry unit and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?

Correct answer: B

Rationale: ST-segment depression can indicate hypokalemia, affecting the heart's electrical conduction. Hypokalemia leads to alterations in the repolarization phase of the cardiac action potential, resulting in ST-segment depression on the ECG. Tall, peaked T waves are indicative of hyperkalemia, not hypokalemia. A prolonged P-R interval is more commonly associated with first-degree heart block. Widening of the QRS complex is typically seen in conditions like bundle branch blocks or ventricular tachycardia, not specifically in hypokalemia.

2. When educating a client with a new prescription for nitroglycerin, which of the following instructions should the nurse include?

Correct answer: D

Rationale: The correct instruction for a client with a new prescription for nitroglycerin is to take the medication at the first sign of chest pain. Nitroglycerin is a vasodilator used to relieve chest pain associated with angina. Taking it at the onset of chest pain ensures prompt relief by dilating blood vessels and increasing blood flow to the heart muscle. Storing nitroglycerin in a cool, dark place helps maintain its potency, while taking it with food can alter its absorption. Timing the medication with bedtime is not necessary, but prompt administration at the first sign of chest pain is crucial for effective management of angina. Choices A, B, and C are incorrect because storing the medication in a cool, dark place, taking it before bedtime, and taking it with food are not essential instructions for nitroglycerin use. The priority is to administer it promptly when chest pain occurs to achieve optimal therapeutic effects.

3. Before administering digoxin (Lanoxin) to a client diagnosed with heart failure, the nurse should perform which assessment?

Correct answer: C

Rationale: Assessing the apical pulse is crucial before administering digoxin because the medication can lead to bradycardia. Monitoring the apical pulse helps determine the heart rate, and digoxin is typically withheld if the pulse is below 60 beats per minute. This assessment is essential to prevent potential adverse effects associated with digoxin administration. Checking the blood pressure (Choice A) is important but not specific to digoxin administration. Obtaining an electrocardiogram (ECG) (Choice B) may provide valuable information but is not the primary assessment needed before administering digoxin. Reviewing the latest electrolyte levels (Choice D) is important for assessing the overall condition but is not the immediate assessment required before administering digoxin.

4. The client's B-type natriuretic peptide (BNP) level is 691 pg/mL. Which intervention should the nurse implement when providing care for the client?

Correct answer: A

Rationale: Elevated BNP levels are indicative of heart failure, which often causes fluid retention and weight gain. Taking daily weights and monitoring trends allows the nurse to assess for changes in fluid status. This intervention helps in evaluating the effectiveness of the treatment plan and identifying worsening heart failure symptoms early. Encouraging fluid intake (Choice B) might exacerbate fluid overload in a client with elevated BNP levels. Elevating the legs (Choice C) and positioning the client supine with the head of the bed at 30 degrees (Choice D) are interventions more suitable for clients with hypotension, not specifically indicated for managing elevated BNP levels.

5. A client has a new prescription for prednisone. Which of the following statements should the nurse include in teaching the client?

Correct answer: A

Rationale: The correct answer is A. Weight gain is a common side effect of prednisone. The nurse should educate the client about the possibility of weight gain and the need to monitor it closely during treatment with prednisone. Choice B is incorrect because increasing vitamin K intake is not specifically related to prednisone therapy. Choice C is incorrect as prednisone is more likely to cause fluid retention rather than increased urinary output. Choice D is incorrect as dark, tarry stools are not a common side effect of prednisone.
