1. The nurse is assisting with the care of a client who is on a continuous heparin infusion for deep vein thrombosis (DVT). Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?

Correct answer: B

Rationale: To evaluate the effectiveness of heparin therapy in a client with DVT, the nurse should monitor the activated partial thromboplastin time (aPTT). The aPTT test helps ensure that the dose of heparin is within the therapeutic range, which is essential for preventing clot formation or excessive bleeding. Monitoring aPTT is crucial in managing patients on heparin therapy to maintain the delicate balance between preventing thrombosis and avoiding hemorrhage. Prothrombin time (PT) and International normalized ratio (INR) are more indicative of warfarin therapy effectiveness, not heparin. Platelet count assesses platelet levels and function, not the effectiveness of heparin therapy for DVT.

2. When teaching a client who has a new prescription for metformin, which of the following instructions should the nurse include?

Correct answer: C

Rationale: The correct instruction for a client starting metformin is to increase fluid intake. This is crucial to prevent gastrointestinal discomfort, a common side effect of metformin. Adequate hydration helps reduce the risk of gastrointestinal upset and ensures the medication is well-tolerated. Option A is generally true for metformin but is not as essential as maintaining proper hydration. Option B is important but not directly related to starting metformin. Option D is incorrect as a metallic taste in the mouth is not typically associated with metformin.

3. A client with myocardial infarction suddenly becomes tachycardic, shows signs of air hunger, and begins coughing frothy, pink-tinged sputum. The nurse listens to breath sounds, expecting to hear which breath sounds bilaterally?

Correct answer: B

Rationale: In this scenario, the client is exhibiting signs of pulmonary edema, which can occur as a complication of myocardial infarction. Crackles are typically heard in cases of pulmonary edema, characterized by fluid accumulation in the lungs. These crackling sounds are heard during inspiration and sometimes expiration and are an indication of fluid-filled alveoli. Therefore, when assessing the client with these symptoms, the nurse would expect to hear crackles bilaterally. Rhonchi, which are coarse rattling respiratory sounds, are typically associated with conditions like bronchitis or pneumonia, not pulmonary edema. Wheezes are high-pitched musical sounds heard in conditions like asthma or COPD, not commonly present in pulmonary edema. Diminished breath sounds suggest decreased airflow or lung consolidation, not typical findings in pulmonary edema.

4. 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.

5. The client is receiving furosemide (Lasix) for heart failure. What potential side effect should the nurse monitor for?

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, causes potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial because hypokalemia can result in cardiac arrhythmias and muscle weakness. Choices B, C, and D are incorrect because furosemide does not typically cause hyperkalemia, hypernatremia, or hypoglycemia.
