1. When teaching a client with a prescription for Phenytoin, which of the following instructions should the nurse include?
- A. Expect the development of a mild rash.
- B. Take the medication on an empty stomach.
- C. Monitor for signs of gingival hyperplasia.
- D. Increase your intake of calcium.
Correct answer: C
Rationale: Phenytoin is known to cause gingival hyperplasia, a condition characterized by overgrowth of gum tissue. The nurse should instruct the client to monitor for signs of gingival hyperplasia, such as swollen or bleeding gums. Good oral hygiene practices are essential to prevent or manage this side effect. Choices A, B, and D are incorrect. Phenytoin does not typically cause a mild rash, should be taken with food to reduce gastrointestinal upset, and does not warrant an increase in calcium intake.
2. Which of the following is not a known effect of the drug Clozapine?
- A. Agranulocytosis
- B. Antipsychotic
- C. Used for Schizophrenia
- D. Hyperactivity
Correct answer: D
Rationale: Clozapine is associated with side effects like agranulocytosis (a serious blood condition), sedation (not hyperactivity), and is used as an antipsychotic to treat schizophrenia. Hyperactivity is not a typical effect of Clozapine, making it the correct answer in this context.
3. A healthcare professional is reviewing the medication list of a client scheduled for surgery. Which of the following medications places the client at risk for increased bleeding during surgery?
- A. Warfarin
- B. Acetaminophen
- C. Ibuprofen
- D. Aspirin
Correct answer: D
Rationale: Aspirin is an anticoagulant that inhibits platelet function, increasing the risk of bleeding during surgery. It is important for the healthcare professional to identify this medication, inform the surgical team, and consider withholding it prior to surgery to reduce the risk of excessive bleeding. Warfarin is also an anticoagulant but can be managed by adjusting the dosage or monitoring INR levels. Acetaminophen and ibuprofen are not associated with increased bleeding risk as they do not affect platelet function like aspirin.
4. A client has a new prescription for Metronidazole to treat an infection. Which of the following instructions should the nurse include?
- A. Avoid alcohol while taking this medication.
- B. Take this medication on an empty stomach.
- C. Increase your intake of dairy products while taking this medication.
- D. Avoid direct sunlight while taking this medication.
Correct answer: A
Rationale: The correct instruction is to avoid alcohol while taking Metronidazole. This is crucial to prevent a disulfiram-like reaction, which can result in severe nausea and vomiting. Alcohol should be avoided for at least 48 hours after completing the medication course as well. Choice B is incorrect because Metronidazole can be taken with food to reduce gastrointestinal side effects. Choice C is incorrect because there is no need to increase dairy product intake while on Metronidazole. Choice D is incorrect because there is no specific instruction to avoid direct sunlight while taking this medication.
5. Which drug undergoes extensive first-pass hepatic metabolism?
- A. Heparin
- B. Insulin
- C. Propranolol
- D. Nitroglycerin
Correct answer: C
Rationale: Propranolol undergoes extensive first-pass hepatic metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration. Heparin (Choice A) is not metabolized by the liver but excreted unchanged by the kidneys. Insulin (Choice B) is a peptide hormone that is not subject to significant first-pass metabolism. Nitroglycerin (Choice D) is primarily metabolized in the blood and tissues, bypassing significant first-pass metabolism in the liver.
