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. A 24-year-old man seeks medical attention for complaints of claudication in the arch of the foot. The nurse also notes superficial thrombophlebitis of the lower leg. What should the nurse check the client for next?

Correct answer: A

Rationale: In this case, the nurse should check the client's smoking history next. Smoking is a significant risk factor for peripheral vascular disease, leading to the development of thrombophlebitis and claudication. It is important to assess this risk factor as it can significantly impact the client's vascular health and the progression of their current symptoms. Choices B, C, and D are incorrect because they are not directly related to the symptoms described by the client. Recent exposure to allergens or insect bites would typically present with different symptoms, and familial tendency toward peripheral vascular disease is not the immediate concern in this case.

3. A client has a new prescription for digoxin. Which of the following instructions should the nurse include during discharge teaching?

Correct answer: B

Rationale: The correct answer is B: 'Monitor heart rate daily.' When a client is prescribed digoxin, it is essential to monitor heart rate daily because digoxin can cause bradycardia, a condition characterized by a slow heart rate. Monitoring the heart rate regularly allows the client to promptly identify any signs of bradycardia and seek medical attention if needed. Choices A, C, and D are incorrect because taking digoxin with food, avoiding grapefruit juice, and increasing potassium-rich foods are not specific instructions related to managing the side effects or monitoring parameters of digoxin therapy.

4. A client with a history of coronary artery disease (CAD) is being discharged with a prescription for aspirin. Which instruction should the nurse reinforce with the client?

Correct answer: C

Rationale: The correct instruction is to take the aspirin with food to reduce the risk of stomach irritation. This is crucial for clients with a history of coronary artery disease as it helps minimize gastrointestinal side effects like irritation and bleeding. Option A is incorrect because aspirin should not be taken on an empty stomach to prevent stomach upset. Option B is incorrect because discontinuing aspirin at the first sign of stomach discomfort can be harmful, and a healthcare provider should be consulted instead. Option D is incorrect because aspirin is often prescribed for prevention in cardiovascular conditions, not just for chest pain relief.

5. The healthcare provider assesses a client who has been prescribed furosemide (Lasix) for cardiac disease. Which electrocardiographic change would be a concern for a client taking a diuretic?

Correct answer: D

Rationale: The presence of a U wave is often associated with hypokalemia, a possible side effect of diuretic therapy like furosemide. Hypokalemia can lead to U wave formation on an electrocardiogram, making the presence of U waves a concerning finding in clients taking diuretics. Tall, spiked T waves are typically seen in hyperkalemia, not hypokalemia. A prolonged QT interval is more commonly associated with conditions like Long QT syndrome or certain medications, not specifically with diuretics. A widening QRS complex is usually seen in conditions affecting the conduction system of the heart, such as bundle branch blocks, rather than being directly related to diuretic use.
