1. A client with deep vein thrombosis has been on heparin continuous infusion for 5 days. The provider prescribes warfarin PO without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following statements should the nurse make?
- A. Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level.
- B. I will call the provider to get a prescription for discontinuing the IV heparin today.
- C. Both heparin and warfarin work together to dissolve the clots.
- D. The IV heparin increases the effects of the warfarin and decreases the length of your hospital stay.
Correct answer: A
Rationale: The correct answer is A because warfarin takes several days to reach a therapeutic level and exert its full anticoagulant effect. During this time, the IV heparin is continued to prevent clotting until the warfarin is effective. Both medications are used together temporarily for this reason. Discontinuing heparin prematurely can increase the risk of clot formation. Therefore, the nurse should explain to the client that the IV heparin will be continued until the warfarin reaches a therapeutic level.
2. A client has a new prescription for Amlodipine. Which of the following instructions should the nurse include during discharge teaching?
- A. Take the medication at bedtime.
- B. Avoid drinking grapefruit juice.
- C. Increase your intake of high-sodium foods.
- D. Expect a dry cough.
Correct answer: B
Rationale: The correct instruction for the nurse to include during discharge teaching is to advise the client to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of amlodipine, a calcium channel blocker, leading to increased drug levels in the blood. This can result in potentiated side effects and potential toxicity. Option A is incorrect as amlodipine is usually taken once daily, not specifically at bedtime. Option C is incorrect because high-sodium foods are generally discouraged in individuals with hypertension. Option D is incorrect as a dry cough is not an expected side effect of amlodipine.
3. A nurse is providing discharge teaching to a client who has a new prescription for Warfarin. Which of the following statements should the nurse include?
- A. You should avoid taking aspirin for headaches while on this medication.
- B. You should use a soft toothbrush to brush your teeth.
- C. You should avoid foods that are rich in vitamin K.
- D. You should avoid prolonged exposure to sunlight.
Correct answer: B
Rationale: The correct statement to include in discharge teaching for a client prescribed Warfarin is to use a soft toothbrush to prevent gum bleeding. Warfarin is an anticoagulant that increases the risk of bleeding, so using a soft toothbrush can help prevent gum injury and bleeding. Choice A is incorrect because aspirin, another blood-thinning medication, should generally be avoided while on Warfarin to reduce the risk of bleeding. Choice C is incorrect because clients on Warfarin should maintain a consistent intake of vitamin K-rich foods rather than avoid them completely. Choice D is unrelated to the medication and not a priority teaching point for a client prescribed Warfarin.
4. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?
- A. Use a blood pressure cuff to distend the veins.
- B. Select the antecubital area to insert the IV catheter.
- C. Distend the veins by using a blood pressure cuff.
- D. Direct the client to lower his arm below his heart.
Correct answer: C
Rationale: The correct answer is C. The healthcare professional should distend the veins using a blood pressure cuff to make the veins more visible and accessible for IV catheter insertion. This technique helps reduce the risk of overfilling the vein, which can lead to complications such as hematoma formation. Choices A, B, and D are incorrect because while selecting the antecubital area is often appropriate for IV insertion in adults, the key action in this scenario is to distend the veins using a blood pressure cuff to facilitate the procedure.
5. When does regular insulin typically peak?
- A. 30 minutes to 2 ½ hours
- B. 1 to 3 hours
- C. 6 to 14 hours
- D. 1 to 5 hours
Correct answer: D
Rationale: Regular insulin usually peaks around 1 to 5 hours after administration. This peak time frame is important to consider when managing blood glucose levels and timing meals to coincide with insulin activity. Choice A, '30 minutes to 2 ½ hours,' is incorrect because regular insulin typically peaks later. Choice B, '1 to 3 hours,' is not the most accurate as the peak for regular insulin can extend beyond 3 hours. Choice C, '6 to 14 hours,' is incorrect as this timeframe is more indicative of long-acting insulins, not regular insulin.
