Correct Answer: B

Rationale: The correct instruction for the nurse to include is to advise the client to report a pulse rate below 60 beats per minute. Beta blockers are known to lower heart rate, and a pulse rate below 60 beats per minute may indicate bradycardia, a condition that requires medical attention. Option A, 'Take the medication with a meal,' is incorrect because beta blockers don't necessarily need to be taken with food. Option C, 'Discontinue the medication if dizziness occurs,' is incorrect because abrupt cessation of beta blockers can lead to rebound hypertension and other adverse effects. Option D, 'Avoid drinking grapefruit juice,' is unrelated to beta blockers' mechanism of action or side effects.

Correct Answer: D

Rationale: The correct answer is D. Nitroglycerin sublingual tablets should not be swallowed; they must dissolve under the tongue to be effective. Choice A is correct as nitroglycerin tablets should be stored in their original glass container to prevent degradation. Choice B is correct as sitting or lying down when taking a nitroglycerin tablet helps prevent dizziness or fainting due to a sudden drop in blood pressure. Choice C is correct as taking a nitroglycerin tablet every 5 minutes for a maximum of 3 tablets is the correct protocol for managing angina symptoms.

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.

Correct Answer: C

Rationale: Following a cardiac catheterization, a common complication to monitor for is bleeding or hemorrhage at the catheter insertion site. Hemorrhage is a significant concern due to the potential for rapid blood loss, leading to hypovolemic shock and other serious complications. Monitoring for signs of bleeding, such as swelling, hematoma, or drop in hemoglobin levels, is crucial for timely intervention. Hypertension is not a common complication post-cardiac catheterization; instead, hypotension may occur due to vasovagal response or bleeding. Hyperglycemia is not typically associated with cardiac catheterization unless the client has pre-existing diabetes or stress-induced hyperglycemia.

Correct Answer: A

Rationale: The correct preoperative instruction that the LPN/LVN should reinforce to a client scheduled for a carotid endarterectomy is being NPO after midnight before the surgery. This instruction is essential to prevent aspiration and ensure a safe procedure. Avoiding oral intake helps reduce the risk of complications during anesthesia induction and the surgical process. Choices B, C, and D are incorrect because avoiding deep breathing and coughing, resuming normal eating and drinking, and taking all prescribed medications the morning of surgery are not recommended preoperative instructions for a carotid endarterectomy.
