1. Which lab value is most critical to monitor in a patient receiving digoxin?

Correct answer: A

Rationale: The correct answer is to monitor potassium levels in a patient receiving digoxin. Hypokalemia can potentiate the toxic effects of digoxin, leading to serious cardiac arrhythmias. Monitoring potassium levels helps prevent toxicity. Monitoring sodium levels (Choice B), calcium levels (Choice C), and magnesium levels (Choice D) are also important aspects of patient care, but potassium levels are most critical in patients on digoxin therapy.

2. While caring for a client receiving hemodialysis, which action should the nurse include in the plan of care?

Correct answer: B

Rationale: The correct action the nurse should include in the plan of care when caring for a client receiving hemodialysis is to check the vascular access site for bleeding after dialysis. This is crucial to monitor for any signs of bleeding or complications at the access site. Withholding all medications until after dialysis (Choice A) is not necessary unless specified for certain medications. Rehydrating with dextrose 5% in water for hypotension (Choice C) is not appropriate for addressing hypotension related to hemodialysis. Giving an antibiotic 30 minutes before dialysis (Choice D) is not typically indicated unless there is a specific medical indication for prophylactic antibiotic use.

3. A nurse is caring for a client who is receiving warfarin therapy. Which of the following laboratory results indicates the need for an increase in the dose of warfarin?

Correct answer: B

Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

4. A nurse is reviewing the medical record of a client who is 24 hours postoperative following abdominal surgery. Which of the following findings should the nurse report to the provider?

Correct answer: C

Rationale: The correct answer is C. A temperature of 38.6°C (101.5°F) is above the normal range and indicates a fever, which is a concerning finding postoperatively. Fever can be a sign of infection, so the nurse should report this finding to the provider for further evaluation and intervention. Choices A, B, and D are within expected parameters for a client who is 24 hours postoperative following abdominal surgery and do not require immediate reporting. A heart rate of 90/min, serosanguineous drainage in the surgical drain, and a urinary output of 60 mL/hr are all common postoperative findings that do not raise immediate concerns.

5. A client is recovering from an acute myocardial infarction that occurred 3 days ago. Which of the following instructions should the nurse include?

Correct answer: D

Rationale: After an acute myocardial infarction, it is important to involve the client in cardiac rehabilitation to help them recover and manage their condition effectively. Performing an ECG every 12 hours is not necessary unless there are specific indications for it. Placing the client in a supine position may not be ideal as it can increase venous return, potentially worsening cardiac workload. Drawing troponin levels every 4 hours is excessive and not recommended as troponin levels usually peak within 24-48 hours post-MI and then gradually decline.
