1. A client has been taking levothyroxine for 6 months. Which of the following findings indicates that the medication is effective?

Correct answer: C

Rationale: In a client taking levothyroxine for thyroid hormone replacement, decreased TSH levels indicate that the medication is effective. TSH levels decrease as the thyroid hormone levels are adequately replaced by levothyroxine, signaling a positive response to treatment. Choices A, B, and D are incorrect because weight gain, increased heart rate, and elevated blood pressure are not expected findings indicating the effectiveness of levothyroxine therapy. Weight gain may suggest inadequate dosing, while increased heart rate and elevated blood pressure could indicate over-replacement or side effects of the medication.

2. Why should the client diagnosed with rheumatic heart disease be advised to notify the dentist before dental procedures?

Correct answer: A

Rationale: Clients with rheumatic heart disease are at risk for infective endocarditis, a serious infection of the heart lining or valves. They need prophylactic antibiotics before invasive procedures, including dental work, to prevent this life-threatening complication. While dysrhythmias with high-speed drills, adverse reactions to local anesthesia, and the risk of heart failure during stressful events are all concerns for clients with heart conditions, the primary reason for notifying the dentist before dental procedures in rheumatic heart disease is the need for prophylactic antibiotics to prevent infective endocarditis.

3. The LPN/LVN is assisting in the care of a client with chronic heart failure who is receiving furosemide (Lasix). Which instruction should the nurse reinforce with the client?

Correct answer: B

Rationale: The correct instruction for the nurse to reinforce with the client is to increase potassium intake by eating bananas and oranges. Furosemide can lead to potassium loss, potentially causing hypokalemia. By increasing potassium intake through diet, the client can help prevent this electrolyte imbalance and maintain overall health. Choices A, C, and D are incorrect. Limiting fluid intake is not the appropriate instruction, as furosemide is a diuretic that already helps in fluid management. Weighing once a week is not as crucial as monitoring potassium levels, and taking the medication at night does not impact potassium levels.

4. A healthcare professional is reviewing laboratory results for a client who has been taking carbamazepine. Which of the following findings should the healthcare professional report to the provider?

Correct answer: A

Rationale: A WBC count of 3,000/mm3 indicates leukopenia, a serious side effect of carbamazepine. Leukopenia can increase the risk of infections due to decreased white blood cell count, which is important to report to the provider for further evaluation and management. Platelet count within normal range (choice B), hemoglobin level within normal range (choice C), and serum potassium level within normal range (choice D) are not directly associated with carbamazepine use and do not require immediate reporting as they do not indicate a serious adverse effect.

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

Correct answer: D

Rationale: Instructing the client to take nitroglycerin at the first sign of chest pain is crucial for immediate relief of angina symptoms. Nitroglycerin is a fast-acting medication that helps dilate blood vessels, improving blood flow to the heart muscle. Therefore, prompt administration at the onset of chest pain is essential to alleviate anginal episodes effectively. Choices A, B, and C are incorrect because storing the medication properly, taking it as directed, or before meals are not specific instructions for managing acute anginal episodes, which require immediate action for symptom relief.
