Nursing Elites

1. A client receiving warfarin (Coumadin) therapy should have which of the following laboratory results reviewed to evaluate the effectiveness of the therapy?

• A. Complete blood count (CBC).
• B. Prothrombin time (PT).
• C. International normalized ratio (INR).
• D. Partial thromboplastin time (PTT).

Correct answer: C

Rationale: The correct answer is C: International normalized ratio (INR). The INR is the most appropriate laboratory result to review when evaluating the effectiveness of warfarin (Coumadin) therapy. Warfarin is an anticoagulant medication, and the INR helps determine if the dosage is within a therapeutic range to prevent clotting or bleeding complications. Choice A, a Complete Blood Count (CBC), provides information about the cellular components of blood but does not directly assess the anticoagulant effects of warfarin. Choice B, Prothrombin time (PT), measures the time it takes for blood to clot but is not as specific for monitoring warfarin therapy as the INR. Choice D, Partial Thromboplastin Time (PTT), evaluates the intrinsic pathway of coagulation and is not the primary test used to monitor warfarin therapy.

2. A client arrived to the medical-surgical unit 4 hours after a transurethral resection of the prostate (TURP). A triple-lumen catheter for continuous bladder irrigation with normal saline is infusing, and the nurse observes dark, pink-tinged outflow with blood clots in the tubing and collection bag. Which action should the nurse take?

• A. Monitoring catheter drainage
• B. Decreasing the flow rate
• C. Irrigating the catheter manually
• D. Discontinuing infusing the solution

Correct answer: C

Rationale: In this scenario, the nurse should choose option C - irrigating the catheter manually. This action can help clear the clots from the catheter and ensure proper bladder drainage. Monitoring catheter drainage (option A) alone may not address the issue of clots obstructing the flow. Decreasing the flow rate (option B) could potentially worsen clot formation. Discontinuing the infusing solution (option D) without addressing the clots first may lead to inadequate irrigation and increase the risk of complications.

3. A client is being prepared for transfer to the operating room. Which of the following actions should the nurse take in the care of this client at this time?

• A. Ensuring that the client has voided
• B. Administering all daily medications
• C. Practicing postoperative breathing exercises
• D. Verifying that the client has not eaten for the last 24 hours

Correct answer: A

Rationale: The nurse should ensure that the client has voided, especially if a Foley catheter is not in place. This step is important to prevent urinary retention during the surgical procedure. Administering all daily medications just before surgery is not standard practice. The physician typically provides specific orders regarding which medications can be taken with a sip of water before surgery. Postoperative breathing exercises are usually taught after surgery to prevent complications like atelectasis. Verifying that the client has not eaten for the last 24 hours is not a standard preoperative practice; instead, the client is usually instructed to fast for a specific period before surgery to reduce the risk of aspiration during anesthesia.

4. In a patient with type 1 diabetes, which of the following is a sign of diabetic ketoacidosis (DKA)?

• A. Polyuria
• B. Bradycardia
• C. Dry skin
• D. Tachycardia

Correct answer: D

Rationale: Tachycardia is a sign of diabetic ketoacidosis (DKA) in a patient with type 1 diabetes. In DKA, the body responds to hyperglycemia and dehydration by increasing heart rate. Polyuria (increased urination) is a symptom of diabetes but not specific to DKA. Bradycardia (slow heart rate) and dry skin are not typical signs of DKA; instead, tachycardia and other signs of volume depletion are more common.

5. A nurse reviews a female client’s laboratory results. Which result from the client’s urinalysis should the nurse recognize as abnormal?

• A. pH 5.6
• B. Ketone bodies present
• C. Specific gravity of 1.020
• D. Clear and yellow color

Correct answer: B

Rationale: The correct answer is B: Ketone bodies present. Ketone bodies in urine indicate abnormal metabolism, specifically the incomplete breakdown of fatty acids. Normally, there should be no ketones present in urine. Ketone bodies are produced when the body uses fat sources instead of glucose for cellular energy. A pH range between 4.6 and 8, a specific gravity between 1.005 and 1.030, and clear yellow color in urine are considered normal findings for a female client’s urinalysis. Therefore, options A, C, and D are within normal ranges and not indicative of abnormal results in the urinalysis.
