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?
- 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.
2. Salicylic acid is prescribed for a client with a diagnosis of psoriasis. The nurse monitors the client, knowing that which of the following would indicate the presence of systemic toxicity from this medication?
- A. Tinnitus
- B. Diarrhea
- C. Constipation
- D. Decreased respirations
Correct answer: A
Rationale: The correct answer is A: Tinnitus. Salicylic acid can lead to systemic toxicity, known as salicylism, which may manifest with symptoms like tinnitus, dizziness, hyperventilation, and mental disturbances. Tinnitus is a common early sign of salicylism and should be monitored closely by the nurse to prevent further complications.
3. A client is receiving morphine sulfate subcutaneously for pain. Because morphine sulfate has been prescribed for this client, which nursing action would be included in the plan of care?
- A. Encourage fluid intake.
- B. Monitor the client's temperature.
- C. Maintain the client in a supine position.
- D. Encourage the client to cough and deep breathe.
Correct answer: D
Rationale: Morphine sulfate suppresses the cough reflex, which can lead to the retention of secretions in the lungs. Encouraging the client to cough and deep breathe helps prevent pneumonia by clearing the airways of any accumulated secretions. This intervention is crucial in clients receiving morphine sulfate to maintain optimal respiratory function.
4. When administering etanercept (Enbrel) to a client with rheumatoid arthritis for 3 weeks, what is the most important assessment for the nurse to perform?
- A. Assessing the injection site for itching and edema
- B. Monitoring white blood cell counts and platelet counts
- C. Evaluating for fatigue and joint pain in the client
- D. Checking for a metallic taste in the mouth and loss of appetite
Correct answer: B
Rationale: The priority when administering etanercept (Enbrel) to a client with rheumatoid arthritis is to monitor white blood cell counts and platelet counts. Etanercept can lead to infections and pancytopenia, making it crucial to assess for changes in these blood parameters to detect any potential complications early on.
5. A client is prescribed metronidazole (Flagyl) for a trichomoniasis infection. Which of the following should the nurse include in the teaching plan?
- A. Avoid consuming alcohol while taking this medication.
- B. Take the medication with food.
- C. Increase fluid intake to prevent kidney stones.
- D. Report any gastrointestinal upset to the healthcare provider.
Correct answer: A
Rationale: The correct answer is A. Metronidazole (Flagyl) can cause a disulfiram-like reaction when taken with alcohol, resulting in severe nausea, vomiting, and headache. Therefore, the client should be advised to avoid alcohol while taking this medication to prevent adverse effects. Avoiding alcohol is crucial to prevent these reactions and ensure the effectiveness of the treatment. The other options are not directly related to the specific medication or the condition being treated.
