1. A client is taking Humulin NPH insulin daily every morning. The nurse reinforces instructions for the client and tells the client that the most likely time for a hypoglycemic reaction to occur is:
- A. 2 to 4 hours after administration
- B. 4 to 12 hours after administration
- C. 16 to 18 hours after administration
- D. 18 to 24 hours after administration
Correct answer: B
Rationale: Humulin NPH is an intermediate-acting insulin with a peak action time of 4 to 12 hours after administration. During this period, the risk of hypoglycemic reactions is highest. It is important for the client to be aware of this timing to prevent, recognize, and manage hypoglycemia effectively.
2. A client is instructed to take levothyroxine (Synthroid). The medication should be taken:
- A. With food
- B. At lunchtime
- C. On an empty stomach
- D. At bedtime with a snack
Correct answer: C
Rationale: Levothyroxine should be taken on an empty stomach to enhance absorption. Taking it with food or at bedtime can interfere with its absorption, reducing its effectiveness. Therefore, it is essential for the client to take levothyroxine on an empty stomach to ensure optimal therapeutic outcomes.
3. A client is receiving dietary instructions from a nurse regarding warfarin sodium (Coumadin) therapy. The nurse advises the client to avoid which food item?
- A. Grapes
- B. Spinach
- C. Watermelon
- D. Cottage cheese
Correct answer: B
Rationale: The correct answer is B: Spinach. Spinach is high in vitamin K, which antagonizes the effects of warfarin sodium, an anticoagulant medication. Clients taking warfarin should avoid consuming foods rich in vitamin K, like spinach, to maintain the medication's effectiveness. Grapes (choice A), watermelon (choice C), and cottage cheese (choice D) do not interfere with the effects of warfarin, so they are safe for the client to consume while on warfarin therapy.
4. Nalidixic acid (NegGram) is prescribed for a client with a urinary tract infection. On review of the client's record, the nurse notes that the client is taking warfarin sodium (Coumadin) daily. Which prescription should the nurse anticipate for this client?
- A. Discontinuation of warfarin sodium (Coumadin)
- B. A decrease in the warfarin sodium (Coumadin) dosage
- C. An increase in the warfarin sodium (Coumadin) dosage
- D. A decrease in the usual dose of nalidixic acid (NegGram)
Correct answer: B
Rationale: Nalidixic acid can intensify the effects of oral anticoagulants by displacing these agents from binding sites on plasma proteins. When an oral anticoagulant, like warfarin sodium (Coumadin), is combined with nalidixic acid, a decrease in the anticoagulant dosage may be necessary to avoid excessive anticoagulation and potential bleeding risks. Therefore, the correct action for the nurse to anticipate in this situation is a decrease in the warfarin sodium (Coumadin) dosage. Choice A is incorrect because discontinuing warfarin sodium abruptly can lead to thrombosis or embolism. Choice C is incorrect as increasing the warfarin sodium dosage can potentiate the anticoagulant effect, leading to bleeding complications. Choice D is incorrect as reducing the dose of nalidixic acid would not directly address the interaction with warfarin sodium.
5. A client with chronic obstructive pulmonary disease (COPD) is prescribed tiotropium (Spiriva). Which instruction should the nurse include in the teaching plan?
- A. Use the medication as a rescue inhaler.
- B. Rinse your mouth after using the inhaler.
- C. Take the medication on an empty stomach.
- D. Take the medication with a full glass of water.
Correct answer: B
Rationale: Tiotropium (Spiriva) is not a rescue inhaler but a maintenance medication for COPD. The correct instruction for the nurse to include in the teaching plan is to advise the client to rinse their mouth after using the inhaler. This practice helps prevent dry mouth and throat irritation, common side effects of tiotropium. There are no specific recommendations to take tiotropium on an empty stomach or with a full glass of water.
