Nursing Elites

1. When a client taking warfarin sodium (Coumadin) is prescribed ciprofloxacin (Cipro), the nurse should closely monitor the client for which potential effect of this drug interaction?

• A. Increased risk of bleeding
• B. Decreased warfarin effectiveness
• C. Increased risk of thrombosis
• D. Decreased ciprofloxacin effectiveness

Correct answer: A

Rationale: When ciprofloxacin (Cipro) is given with warfarin sodium (Coumadin), it can potentiate the effects of warfarin, leading to an increased risk of bleeding. Therefore, the nurse should closely monitor the client's INR levels and watch for signs of bleeding such as bruising, petechiae, or black tarry stools.

2. 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.

3. A client receiving nitrofurantoin (Macrodantin) calls the health care provider's office complaining of side effects related to the medication. Which side effect indicates the need to stop treatment with this medication?

• A. Nausea
• B. Diarrhea
• C. Anorexia
• D. Cough and chest pain

Correct answer: D

Rationale: Pulmonary reactions such as cough and chest pain are serious side effects associated with nitrofurantoin that require immediate discontinuation of the medication to prevent potential severe respiratory complications.

4. In a client with chronic renal failure receiving epoetin alfa (Epogen, Procrit), which laboratory result would indicate a therapeutic effect of the medication?

• A. Hematocrit of 32%
• B. Platelet count of 400,000 cells/mm³
• C. White blood cell count of 6000 cells/mm³
• D. Blood urea nitrogen (BUN) level of 15 mg/dL

Correct answer: A

Rationale: A hematocrit of 32% indicates a therapeutic effect of epoetin alfa in a client with chronic renal failure. Epoetin alfa is used to treat anemia in these patients by stimulating red blood cell production, leading to an increase in the hematocrit level. Monitoring the hematocrit is essential to assess the response to epoetin alfa therapy.

5. The client with non-Hodgkin's lymphoma is receiving daunorubicin (DaunoXome). Which of the following would indicate to the nurse that the client is experiencing a toxic effect related to the medication?

• A. Fever
• B. Diarrhea
• C. Complaints of nausea and vomiting
• D. Crackles on auscultation of the lungs

Correct answer: D

Rationale: Crackles on auscultation of the lungs would indicate a toxic effect related to daunorubicin, known to cause cardiotoxicity. Cardiotoxicity can manifest as heart failure, abnormal ECG findings, or cardiomyopathy. It is crucial for the nurse to monitor for signs of cardiotoxicity to ensure timely intervention and prevent further complications. Fever, diarrhea, and complaints of nausea and vomiting are common side effects of daunorubicin but do not specifically indicate a toxic effect like cardiotoxicity.
