1. When caring for a client prescribed warfarin, which laboratory test should the nurse monitor to evaluate the therapeutic effect of the medication?
- A. aPTT
- B. Platelet count
- C. BUN
- D. PT/INR
Correct answer: D
Rationale: The correct laboratory test to monitor the therapeutic effect of warfarin is the PT/INR. Warfarin affects blood clotting, and the PT/INR levels indicate the effectiveness of the medication in preventing clot formation. Therefore, monitoring PT/INR levels helps ensure that the client is within the therapeutic range and is protected from potential complications related to clotting. Choice A (aPTT) is incorrect because while it measures the clotting time, it is not the preferred test for monitoring warfarin therapy. Choice B (Platelet count) is incorrect as it assesses the number of platelets and not the medication's therapeutic effect. Choice C (BUN) is unrelated to monitoring the effects of warfarin therapy and is primarily used to assess kidney function.
2. A nurse is caring for a client who is 2 hours postoperative following a cholecystectomy. Which of the following actions should the nurse take to prevent postoperative complications?
- A. Instruct the client to perform deep breathing and coughing exercises.
- B. Have the client wear sequential compression devices (SCDs).
- C. Place the client in a supine position with the head of the bed flat.
- D. Encourage the client to ambulate every 2 hours.
Correct answer: B
Rationale: The correct answer is B: Have the client wear sequential compression devices (SCDs). Following a cholecystectomy, the client is at risk for venous thromboembolism (VTE) due to reduced mobility and surgical stress. SCDs help prevent VTE by promoting venous return and reducing the risk of blood clots. Choices A, C, and D are incorrect. While deep breathing and coughing exercises are essential postoperatively, SCDs take precedence in preventing VTE. Placing the client in a supine position with the head of the bed flat can increase the risk of respiratory complications. Encouraging ambulation is important, but SCDs are a higher priority in this situation to prevent VTE.
3. The nurse is closely following a patient who began treatment with testosterone several months earlier. When assessing the patient for potential adverse effects of treatment, the nurse should prioritize which of the following assessments?
- A. Skin inspection for developing lesions
- B. Lung function testing
- C. Assessment of serum calcium levels
- D. Assessment of arterial blood gases
Correct answer: C
Rationale: In patients receiving testosterone therapy, the nurse should prioritize assessing serum calcium levels. Testosterone therapy can lead to hypercalcemia, making the evaluation of serum calcium levels crucial. Skin inspection for developing lesions, lung function testing, and arterial blood gas assessment are not the priority assessments for potential adverse effects of testosterone therapy. Skin inspection may be relevant for dermatological side effects, lung function testing and arterial blood gas assessment are not directly related to the common side effects of testosterone therapy.
4. A nurse is assessing a client who is postoperative following a thyroidectomy. Which of the following findings should the nurse report to the provider?
- A. Serum calcium level of 8 mg/dL.
- B. Urine output of 60 mL/hr.
- C. Heart rate of 110/min.
- D. Temperature of 37.5°C (99.5°F).
Correct answer: C
Rationale: The correct answer is C. A heart rate of 110/min is elevated and may indicate hypocalcemia, a potential complication following a thyroidectomy. Elevated heart rate can be a sign of hypocalcemia due to the close relationship between calcium levels and cardiac function. Option A, serum calcium level of 8 mg/dL, is within the normal range (8.5-10.5 mg/dL) and would not be a cause for concern post-thyroidectomy. Option B, urine output of 60 mL/hr, is within the normal range for urine output and not typically a priority finding post-thyroidectomy. Option D, a temperature of 37.5°C (99.5°F), is slightly elevated but not a critical finding post-thyroidectomy unless accompanied by other symptoms.
5. After routine patient contact, how long should hand washing last at least?
- A. 30 seconds
- B. 1 minute
- C. 2 minutes
- D. 3 minutes
Correct answer: A
Rationale: Proper hand washing for 30 seconds is recommended after routine patient contact as it effectively removes pathogens. This duration ensures thorough cleaning without excessive time consumption, promoting infection control and prevention.
