1. A client with a diagnosis of schizophrenia is prescribed clozapine. The nurse should monitor the client for which potential side effect?
- A. Agranulocytosis
- B. Dry mouth
- C. Weight gain
- D. Hypersalivation
Correct answer: A
Rationale: The correct answer is Agranulocytosis. Clozapine is known to potentially cause agranulocytosis, a serious condition characterized by a dangerously low white blood cell count. Monitoring white blood cell counts is crucial to detect this side effect early and prevent complications. Choices B, C, and D are incorrect because dry mouth, weight gain, and hypersalivation are not typically associated with clozapine use. While dry mouth can be a common side effect of some antipsychotic medications, it is not specifically linked to clozapine. Weight gain can occur with certain antipsychotics, but clozapine is more commonly associated with metabolic side effects. Hypersalivation is not a common side effect of clozapine.
2. What instruction should the nurse include in the teaching plan for a client prescribed ranitidine for a peptic ulcer?
- A. Take this medication in the morning before breakfast.
- B. Take this medication with meals.
- C. Avoid taking this medication with antacids.
- D. Take this medication at bedtime.
Correct answer: A
Rationale: The correct instruction for a client prescribed ranitidine for a peptic ulcer is to take the medication in the morning before breakfast. This timing helps reduce stomach acid production throughout the day, providing optimal therapeutic effects. Option B is incorrect because taking ranitidine with meals is not the recommended timing. Option C is incorrect as there is no specific contraindication against taking ranitidine with antacids. Option D is incorrect as the medication should not be taken at bedtime but rather in the morning before breakfast.
3. A female client who started chemotherapy three days ago for cancer of the breast calls the clinic reporting that she is so upset she cannot sleep. The client has several PRN medications available. Which drug should the nurse instruct her to take?
- A. Ondansetron 8mgPO no
- B. Lorazepam 2mg PO bedtime
- C. Oxycodone, acetylsalicylic acid one tablet q4 hours PRN
- D. Acetaminophen, diphenhydramine 2 capsules bedtime
Correct answer: D
Rationale: Acetaminophen and diphenhydramine help with sleep without severe side effects.
4. The patient is prescribed cimetidine (Tagamet) orally. What should the nurse consider about administering this drug?
- A. Administer the drug with the first bite of food
- B. Administer the drug immediately after meals
- C. Administer the drug 30 minutes after meals
- D. Administer the drug 30 minutes before meals
Correct answer: D
Rationale: Cimetidine is best absorbed when taken 30 minutes before meals to decrease stomach acid. Administering it before meals allows for optimal absorption and effectiveness of the medication. Choices A, B, and C are incorrect because administering cimetidine with food, immediately after meals, or 30 minutes after meals may not provide the best conditions for absorption. Taking it before meals ensures that the drug is absorbed properly and can exert its intended effects.
5. A practical nurse (PN) is preparing to administer enoxaparin to a client. What is the most important action for the PN to take before administering this medication?
- A. Assess the client's blood pressure.
- B. Check the client's platelet count.
- C. Monitor the client's urine output.
- D. Review the client's blood glucose level.
Correct answer: B
Rationale: The correct answer is to check the client's platelet count. Enoxaparin can lead to thrombocytopenia (low platelet count), which can increase the risk of bleeding. Therefore, assessing the platelet count before administering enoxaparin is crucial to ensure that it is within a safe range. Assessing the client's blood pressure (Choice A) is not directly related to enoxaparin administration. Monitoring urine output (Choice C) and reviewing blood glucose levels (Choice D) are not essential actions before administering enoxaparin.
