1. 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?

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.

2. A client is receiving vancomycin (Vancocin). Which of the following is the most important action for the nurse to take?

Correct answer: A

Rationale: The most important action for the nurse to take when a client is receiving vancomycin is to monitor for signs of nephrotoxicity. Vancomycin can cause kidney damage, so monitoring kidney function and signs of nephrotoxicity are crucial to prevent harm. While monitoring for ototoxicity and ensuring adequate hydration are important nursing actions, they are not as critical as preventing nephrotoxicity when administering vancomycin.

3. While assisting in caring for a pregnant client receiving intravenous magnesium sulfate for preeclampsia management, a nurse notes the client's absent deep tendon reflexes. What determination should the nurse make based on this data?

Correct answer: D

Rationale: When a pregnant client receiving intravenous magnesium sulfate for preeclampsia management exhibits absent deep tendon reflexes, this indicates magnesium toxicity. Magnesium toxicity can occur as a complication of magnesium sulfate therapy, leading to suppressed reflexes. It is crucial for the nurse to recognize this sign promptly and report it to prevent further complications or harm to the client.

4. Heparin sodium is prescribed for the client. The nurse expects that the healthcare provider will prescribe which of the following to monitor for a therapeutic effect of the medication?

Correct answer: D

Rationale: The correct answer is D, activated partial thromboplastin time (aPTT). Heparin affects the intrinsic pathway of coagulation. Monitoring aPTT helps ensure that heparin sodium is within the therapeutic range to prevent clot formation. Hematocrit and hemoglobin levels assess red blood cell concentrations and are not specific to monitoring heparin therapy. Prothrombin time (PT) is used to monitor the therapeutic effect of warfarin sodium, which affects the extrinsic pathway of coagulation, not heparin.

5. A client is receiving furosemide (Lasix) and is being discharged. What should the nurse include in the teaching plan?

Correct answer: C

Rationale: The correct answer is to instruct the client to change positions slowly to prevent dizziness. Furosemide (Lasix) is a diuretic that can lead to orthostatic hypotension, causing dizziness. Consuming potassium-rich foods is essential to prevent hypokalemia when taking furosemide. Taking the medication in the morning helps reduce the need for frequent urination at night. Encouraging the client to maintain an adequate fluid intake is crucial to prevent dehydration while on this medication.
