A nurse is planning care for a client who has a new prescription for warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the therapy?
- A. Serum calcium level
- B. Platelet count
- C. INR
- D. WBC count
Correct Answer: C
Rationale: Corrected Rationale: The nurse should monitor the client's INR to determine the effectiveness of warfarin therapy. INR monitoring is crucial as it reflects the blood's ability to clot properly. Warfarin is commonly used as an anticoagulant, and maintaining the INR within the therapeutic range ensures that the client is protected from both clotting and bleeding events. Monitoring serum calcium levels, platelet count, or WBC count is not directly related to assessing the effectiveness of warfarin therapy.

A nurse is teaching a client about home care following cataract surgery. Which of the following statements should the nurse include?
- A. You should wear a protective eye shield while sleeping.
- B. You should avoid bending over to pick things up.
- C. You should apply pressure to your eye if you feel pain.
- D. You should resume wearing your regular glasses immediately.
Correct Answer: A
Rationale: The correct answer is A: 'You should wear a protective eye shield while sleeping.' After cataract surgery, wearing a protective eye shield while sleeping is crucial to prevent accidental injury to the eye. Choice B is incorrect because patients should indeed avoid bending over, but it is not the most important instruction among the options provided. Choice C is incorrect because applying pressure to the eye if pain is felt can be harmful and should not be advised. Choice D is incorrect because patients should not resume wearing their regular glasses immediately post cataract surgery; they should wait until their healthcare provider permits.
A client has a new prescription for furosemide. Which of the following instructions should the nurse include?
- A. Take this medication with a meal.
- B. Increase your intake of potassium-rich foods.
- C. Avoid prolonged exposure to sunlight.
- D. Limit your intake of calcium-rich foods.
Correct Answer: B
Rationale: The correct instruction for a client taking furosemide is to increase their intake of potassium-rich foods. Furosemide is a loop diuretic that can lead to potassium loss, so increasing potassium-rich foods helps prevent hypokalemia. Choice A is incorrect because furosemide is usually taken on an empty stomach. Choice C is unrelated to furosemide therapy. Choice D is incorrect as there is no need to limit calcium-rich foods while taking furosemide.
A client with osteoporosis needs to increase calcium intake. Which of the following foods should be recommended by the nurse?
- A. Carrots
- B. Broccoli
- C. Chicken
- D. Bananas
Correct Answer: B
Rationale: The correct answer is B: Broccoli. Broccoli is rich in calcium and is a suitable food to recommend to clients with osteoporosis to increase their calcium intake. Carrots, chicken, and bananas are not as high in calcium content compared to broccoli and therefore not the most appropriate choices for increasing calcium intake in clients with osteoporosis.
A nurse is caring for a client who is at risk for developing deep vein thrombosis (DVT). Which of the following actions should the nurse implement?
- A. Massage the client's legs every 2 hours.
- B. Encourage the client to remain on bed rest.
- C. Apply sequential compression devices to the client's legs.
- D. Administer anticoagulants as prescribed.
Correct Answer: C
Rationale: The correct action the nurse should implement is to apply sequential compression devices to the client's legs. This intervention helps prevent venous stasis and reduce the risk of deep vein thrombosis (DVT). Massaging the client's legs may dislodge a clot and is contraindicated in this situation (choice A). Encouraging bed rest may increase the risk of DVT due to prolonged immobility (choice B). While administering anticoagulants is a common treatment for DVT, in this case, the question is about preventive measures, and using sequential compression devices is a non-pharmacological approach.
Which lab value should be monitored in a patient on digoxin?
- A. Monitor potassium levels
- B. Monitor calcium levels
- C. Monitor digoxin levels
- D. Monitor sodium levels
Correct Answer: C
Rationale: The correct answer is to monitor digoxin levels in a patient on digoxin. Digoxin is a medication commonly used to treat heart conditions, and monitoring its levels in the blood is crucial to ensure that the patient is within the therapeutic range and to prevent toxicity. Monitoring potassium levels (Choice A) is important due to the potential of digoxin-induced hypokalemia, but the primary focus should be on monitoring digoxin levels. Monitoring calcium levels (Choice B) and sodium levels (Choice D) are not directly related to digoxin therapy and are not the primary lab values of concern when administering digoxin.
