1. Which lab value is essential for a patient receiving warfarin therapy?

Correct answer: A

Rationale: The correct answer is to monitor the INR (International Normalized Ratio) for a patient receiving warfarin therapy. INR monitoring is crucial to assess the effectiveness of warfarin in preventing blood clots while minimizing the risk of bleeding. Monitoring sodium levels (choice B), potassium levels (choice C), or platelet count (choice D) is not specifically essential for patients on warfarin therapy and does not provide direct information on the drug's anticoagulant effects.

2. A nurse is assessing a client who is postoperative following abdominal surgery and has an indwelling urinary catheter that is draining dark yellow urine at 25 ml/hr. What intervention should the nurse anticipate?

Correct answer: D

Rationale: In this scenario, the nurse should anticipate initiating continuous bladder irrigation. Dark yellow urine output at a rate of 25 ml/hr following abdominal surgery may indicate urinary stasis or obstruction, which could lead to complications like urinary retention. Continuous bladder irrigation helps prevent catheter obstruction and manage urinary retention by ensuring patency and promoting urine flow. Clamping the catheter (Choice A) could lead to urinary stasis and should be avoided. Administering a fluid bolus (Choice B) is not indicated solely based on the urine color and output described. Obtaining a urine specimen for culture and sensitivity (Choice C) may be necessary for assessing infection but does not directly address the issue of urinary stasis or obstruction.

3. Four clients present to the emergency department. The nurse should plan to see which of the following clients first?

Correct answer: D

Rationale: The correct answer is D. A client presenting with symptoms of a stroke, such as slurred speech, disorientation, and headache, requires immediate attention due to the possibility of a neurological emergency. Choices A, B, and C, although concerning, do not present with symptoms as urgent as those of a potential stroke. Dislocated shoulder, sickle cell disease with joint pain, and confusion with febrile illness can be addressed after ensuring the client with stroke-like symptoms receives prompt evaluation and intervention.

4. A nurse is caring for a client who has a new diagnosis of rheumatoid arthritis. Which of the following laboratory findings should the nurse expect?

Correct answer: D

Rationale: The correct answer is D: Positive rheumatoid factor. A positive rheumatoid factor is a common laboratory finding in clients with rheumatoid arthritis, indicating an autoimmune response. Option A, increased WBC count, is not typically associated with rheumatoid arthritis. Option B, decreased hemoglobin, and option C, decreased platelet count, are not specific laboratory findings for rheumatoid arthritis.

5. A nurse is assessing a client who has hypovolemia. Which of the following findings should the nurse expect?

Correct answer: B

Rationale: The correct answer is B: Tachycardia. In hypovolemia, the body responds to decreased fluid volume by increasing the heart rate (tachycardia) to maintain adequate circulation. Bradycardia (Choice A) is not expected in hypovolemia since the heart rate typically increases to compensate for the reduced blood volume. Increased blood pressure (Choice C) is unlikely in hypovolemia as the decreased fluid volume leads to decreased pressure. A bounding pulse (Choice D) is more associated with conditions like hyperthyroidism or fever, not specifically with hypovolemia.
