1. The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin). Which dietary instruction should the nurse include?
- A. Avoid foods high in vitamin K
- B. Increase intake of leafy green vegetables
- C. Consume a consistent amount of foods high in potassium
- D. Limit intake of high-protein foods
Correct answer: A
Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.
2. Which intervention is most important to include in the plan of care for a client at high risk for the development of postoperative thrombus formation?
- A. Instruct the client in the use of the incentive spirometer.
- B. Elevate the head of the bed during all meals.
- C. Use aseptic technique when changing the dressing.
- D. Encourage frequent ambulation in the hallway.
Correct answer: D
Rationale: Thrombus formation is a risk for clients who are immobile postoperatively. Encouraging frequent ambulation helps to prevent stasis in the lower extremities, reducing the risk of thrombus formation. This intervention promotes circulation and prevents blood clot formation, making it the most important intervention in this situation.
3. The healthcare provider obtains a BP reading of 100/88 in the right arm of a client whose blood pressure is typically 120/60 in the same arm. What action should the healthcare provider implement first?
- A. Use an electronic sphygmomanometer to take the BP every 30 minutes.
- B. Retake the blood pressure in the same arm, deflating the cuff slowly.
- C. Ask another healthcare provider to recheck the blood pressure to compare results.
- D. Obtain another blood pressure cuff and retake the blood pressure.
Correct answer: B
Rationale: The healthcare provider should first retake the blood pressure in the right arm, deflating the cuff slowly, because a low systolic and high diastolic blood pressure measurement is often the result of deflating the cuff too rapidly. Taking the BP in the same arm ensures consistency and accuracy of the measurement.
4. A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dL. What type of insulin should the nurse prepare to administer to this client?
- A. Regular insulin
- B. NPH insulin
- C. Lispro insulin
- D. Glargine insulin
Correct answer: A
Rationale: In a client with a blood glucose level of 600 mg/dL, which indicates severe hyperglycemia or diabetic ketoacidosis, the nurse should prepare to administer regular insulin (A). Regular insulin has a rapid onset of action and is the preferred choice for immediate correction of high blood glucose levels. NPH insulin (B), lispro insulin (C), and glargine insulin (D) are not suitable for the rapid correction of severe hyperglycemia.
5. The nurse-manager of a skilled nursing (chronic care) unit is instructing UAPs on ways to prevent complications of immobility. Which intervention should be included in this instruction?
- A. Perform range-of-motion exercises to prevent contractures.
- B. Decrease the client's fluid intake to prevent diarrhea.
- C. Massage the client's legs to reduce the occurrence of embolisms.
- D. Turn the client from side to back every shift.
Correct answer: A
Rationale: Performing range-of-motion exercises is essential in preventing contractures, which are common complications of immobility. These exercises help maintain joint flexibility and muscle strength, reducing the risk of contractures that can lead to functional limitations or pain for the client. Choices B, C, and D are incorrect. Decreasing fluid intake does not prevent immobility complications, but it can lead to dehydration. Massaging the client's legs does not directly address the prevention of immobility complications like contractures. Turning the client from side to back every shift is important for preventing pressure ulcers but does not directly address complications of immobility like contractures.
