1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?
- A. It dissolves blood clots
- B. It prevents the blood from clotting
- C. It thins the blood
- D. It decreases the risk of infection
Correct answer: B
Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.
2. A nurse is assessing the learning needs of a client who is diagnosed with Addison's disease. Which statement indicates that the client needs further teaching?
- A. I should take my medications daily to replace necessary hormones
- B. I need to eat a diet high in protein and carbohydrates
- C. I should avoid drinking fluids with caffeine
- D. I should notify my healthcare provider if I start feeling dizzy
Correct answer: B
Rationale: The correct answer is B. A diet high in protein and carbohydrates is not specifically required for Addison's disease. The focus should be on maintaining a balanced diet that is rich in fruits, vegetables, whole grains, and adequate protein sources. Choice A is correct as adherence to medication therapy is crucial in managing Addison's disease. Choice C is correct as caffeine can exacerbate symptoms of Addison's disease. Choice D is correct as dizziness can be a sign of adrenal crisis in Addison's disease, and prompt notification of healthcare providers is essential.
3. A client with cirrhosis is taking lactulose (Cephulac). Which finding indicates that the lactulose is having the desired effect?
- A. Two to three soft bowel movements per day
- B. Increased serum ammonia levels
- C. Decreased white blood cell count
- D. Soft, formed stool twice a day
Correct answer: A
Rationale: The correct answer is A: 'Two to three soft bowel movements per day.' Lactulose is prescribed to produce soft, regular bowel movements to reduce ammonia levels in clients with cirrhosis. This helps in preventing hepatic encephalopathy. Option B is incorrect because increased serum ammonia levels would indicate that lactulose is not effectively reducing ammonia levels. Option C is incorrect because lactulose does not directly affect white blood cell counts. Option D is incorrect because soft, formed stools twice a day may not be frequent enough to effectively reduce ammonia levels in clients with cirrhosis.
4. The nurse is caring for a client who is 2 days post-op following an abdominal surgery. The client reports feeling something 'give way' in the incision site and there is a small amount of bowel protruding from the wound. What action should the nurse take first?
- A. Apply a sterile saline dressing to the wound
- B. Notify the healthcare provider
- C. Administer pain medication
- D. Cover the wound with an abdominal binder
Correct answer: A
Rationale: In this situation, the priority action for the nurse is to apply a sterile saline dressing to the wound. This helps prevent infection and keeps the wound moist, which is crucial in promoting healing and preventing further complications. Option B, notifying the healthcare provider, is important but should come after addressing the wound. Administering pain medication (Option C) may be necessary but is not the first action to take in this emergency situation. Covering the wound with an abdominal binder (Option D) is not appropriate and may cause further harm by applying pressure to the protruding bowel.
5. An 18-year-old gravida 1, at 41-weeks gestation, is undergoing an oxytocin (Pitocin) induction and has an epidural catheter in place for pain control. With each of the last three contractions, the nurse notes a late deceleration. The client is repositioned and oxygen provided, but the late decelerations continue to occur with each contraction. What action should the nurse take first?
- A. Prepare for immediate cesarean birth
- B. Turn off the oxytocin (Pitocin) infusion
- C. Notify the anesthesiologist that the epidural infusion needs to be disconnected
- D. Apply an internal fetal monitoring device and continue to monitor carefully
Correct answer: B
Rationale: In the scenario described, the presence of late decelerations during contractions indicates fetal compromise. To address this, the nurse's initial action should be to turn off the oxytocin (Pitocin) infusion. Oxytocin can contribute to uteroplacental insufficiency, leading to late decelerations. This intervention aims to improve fetal oxygenation and prevent further stress on the fetus. Immediate cesarean birth is not the first-line action unless other interventions fail. Notifying the anesthesiologist about disconnecting the epidural infusion is not the priority in this situation. Applying an internal fetal monitoring device is invasive and not the immediate step needed when late decelerations are present.
