1. A histamine (H2)-receptor antagonist will be prescribed for a client. The nurse understands that which medications are H2-receptor antagonists? Select one that doesn't apply.
- A. Nizatidine (Axid)
- B. Ranitidine (Zantac)
- C. Famotidine (Pepcid)
- D. Ibuprofen (Motrin)
Correct answer: D
Rationale: H2-receptor antagonists like Nizatidine, Ranitidine, and Famotidine are used to suppress gastric acid secretion, relieve heartburn symptoms, and prevent complications of peptic ulcer disease. Ibuprofen, on the other hand, is a nonsteroidal anti-inflammatory drug (NSAID) commonly used for pain relief and inflammation, but it is not an H2-receptor antagonist. It is essential to differentiate between these medication classes to ensure appropriate treatment for gastrointestinal conditions.
2. A client presenting with complaints of not feeling well is seen in a clinic. The client is taking several medications for the control of heart disease and hypertension, including a beta-blocker, digoxin (Lanoxin), and a diuretic. A tentative diagnosis of digoxin toxicity is made. Which of the following assessment data would support this diagnosis?
- A. Dyspnea, edema, and palpitations
- B. Chest pain, hypotension, and paresthesia
- C. Double vision, loss of appetite, and nausea
- D. Constipation, dry mouth, and sleep disorder
Correct answer: C
Rationale: The correct answer is C. Double vision, loss of appetite, and nausea are classic signs of digoxin toxicity. Other signs may include bradycardia, visual disturbances, and confusion. These symptoms are indicators that the client may be experiencing adverse effects due to elevated levels of digoxin in the system, requiring immediate medical attention to prevent serious complications.
3. A client has been prescribed furosemide (Lasix), and the nurse is monitoring for adverse effects associated with this medication. Which of the following should the nurse recognize as a potential adverse effect? Select one that doesn't apply.
- A. Nausea
- B. Tinnitus
- C. Hypotension
- D. Hypokalemia
Correct answer: A
Rationale: Furosemide is a loop diuretic that can lead to adverse effects such as tinnitus, hypotension, and hypokalemia. While nausea is a common side effect of many medications, it is not typically associated with furosemide. Therefore, the nurse should recognize nausea as a potential adverse effect that doesn't apply to furosemide.
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 Crohn's disease is scheduled to receive an infusion of infliximab (Remicade). The nurse assisting in caring for the client should take which action to monitor the effectiveness of treatment?
- A. Monitoring the leukocyte count for 2 days after the infusion
- B. Checking the frequency and consistency of bowel movements
- C. Checking serum liver enzyme levels before and after the infusion
- D. Carrying out a Hematest on gastric fluids after the infusion is completed
Correct answer: B
Rationale: To monitor the effectiveness of infliximab (Remicade) treatment in a client with Crohn's disease, the nurse should observe the frequency and consistency of bowel movements. Infliximab is an immunomodulator that works to reduce inflammation in the colon, leading to improvements in bowel symptoms such as frequency and consistency. Monitoring these bowel patterns can provide valuable insight into the response to the medication and the overall management of Crohn's disease. Checking the leukocyte count (Choice A) is not specific to monitoring the effectiveness of infliximab for Crohn's disease. Checking serum liver enzyme levels (Choice C) may be important for liver function but does not directly monitor the effectiveness of infliximab. Carrying out a Hematest on gastric fluids (Choice D) is not relevant to monitoring the effectiveness of infliximab in Crohn's disease.
