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

Correct answer: A

Rationale: The correct answer is to instruct the client to monitor their heart rate daily when taking verapamil. Verapamil is a calcium channel blocker that can cause bradycardia, making it crucial to monitor the heart rate regularly to detect any changes promptly. Choice B, taking the medication at bedtime, is not specifically related to verapamil administration. Choice C, avoiding grapefruit juice, is more relevant to medications metabolized by CYP3A4 enzymes, not verapamil. Choice D, taking the medication with food, is not a specific instruction for verapamil, as it can be taken with or without food.

3. The healthcare professional is assisting in the care of a client diagnosed with deep vein thrombosis (DVT). Which instruction should be reinforced to prevent complications?

Correct answer: A

Rationale: Elevating the affected leg using pillows is crucial in managing deep vein thrombosis (DVT) as it helps reduce swelling and promote venous return, thereby decreasing the risk of complications such as pulmonary embolism. This position aids in improving blood circulation and preventing blood clots from forming or worsening in the affected leg. Performing leg exercises while sitting might increase the risk of dislodging a blood clot. While snug compression stockings are beneficial, the primary focus should be on elevation. Avoiding ice packs on injuries is unrelated to DVT management.

4. Prior to a cardiac catheterization, what instruction should the client be reminded of?

Correct answer: A

Rationale: Being NPO (nothing by mouth) for 6 to 8 hours before a cardiac catheterization is crucial to prevent complications such as aspiration during the procedure. This helps ensure the safety and accuracy of the test results by minimizing the risk of food or liquid in the stomach interfering with the procedure. Choice B is incorrect because the client will need to lie still during the procedure to ensure its accuracy. Choice C is incorrect as the client is typically required to lie flat for a few hours after the test, not several hours. Choice D is incorrect as the client is usually not allowed to drink fluids immediately before the test to prevent complications.

5. The nurse is reinforcing instructions to a client with coronary artery disease who is prescribed a low-cholesterol diet. The nurse should advise the client to choose which food item?

Correct answer: B

Rationale: Oatmeal with fresh fruit is a suitable choice for a client with coronary artery disease on a low-cholesterol diet as it is low in cholesterol and provides heart-healthy benefits. Eggs and bacon, cream of chicken soup, and grilled cheese sandwich are higher in cholesterol and may not be as heart-healthy for this client. Eggs and bacon are high in cholesterol, cream of chicken soup may contain saturated fats, and a grilled cheese sandwich typically contains high amounts of fat and cholesterol, making them less suitable choices for a client with coronary artery disease on a low-cholesterol diet.
