LPN Pharmacology Practice Test
1. A healthcare professional is assessing a client who has been taking isoniazid to treat tuberculosis. The healthcare professional should monitor the client for which of the following findings as an adverse effect of the medication?
- A. Diarrhea
- B. Blurred vision
- C. Hearing loss
- D. Jaundice
Correct answer: D
Rationale: Correct. Jaundice is a serious adverse effect of isoniazid due to liver damage. It is essential to monitor for signs of liver toxicity, such as jaundice, while the client is on this medication. Diarrhea is a common side effect of isoniazid, but it is not as serious as liver damage. Blurred vision and hearing loss are not typically associated with isoniazid use.
2. A client has a new prescription for methotrexate. Which of the following instructions should the nurse include?
- A. Avoid consuming dairy products.
- B. Take the medication on an empty stomach.
- C. Increase your intake of folic acid.
- D. Monitor for signs of hyperglycemia.
Correct answer: C
Rationale: Increasing folic acid intake is crucial when taking methotrexate because the medication can lead to folic acid deficiency. Folic acid supplementation helps counteract this deficiency and reduces the risk of adverse effects associated with methotrexate therapy. Choices A, B, and D are incorrect. Avoiding dairy products is not specifically necessary for methotrexate therapy. Methotrexate is usually taken with food to reduce gastrointestinal side effects, so taking it on an empty stomach is not recommended. Monitoring for signs of hyperglycemia is not directly related to methotrexate use.
3. A client has a new prescription for furosemide. Which of the following instructions should the nurse include?
- A. Take the medication with or without food.
- B. Monitor for signs of hypokalemia.
- C. Increase your intake of potassium-rich foods.
- D. Expect an increase in urination.
Correct answer: D
Rationale: The correct instruction to include when a client is prescribed furosemide is to expect an increase in urination. Furosemide is a diuretic that works by increasing urine production, so it is essential for the client to anticipate and understand this effect. Monitoring for signs of hypokalemia and increasing potassium-rich foods are not directly related to furosemide use. Hypokalemia is a potential side effect of furosemide, so monitoring for it is crucial. Increasing potassium-rich foods can help counteract potassium loss due to diuretic use. Taking furosemide with food is not required, as it can be taken with or without food.
4. A client who has a new prescription for warfarin is being educated by a healthcare professional about monitoring for adverse effects. Which of the following statements by the client indicates an understanding of the teaching?
- A. 'I should use a soft toothbrush to brush my teeth.'
- B. 'I will double my dose if I miss one.'
- C. 'I should increase my intake of leafy green vegetables.'
- D. 'I will contact my doctor if I notice any unusual bleeding or bruising.'
Correct answer: D
Rationale: The correct answer is D: 'I will contact my doctor if I notice any unusual bleeding or bruising.' This statement indicates a good understanding of the teaching regarding warfarin. Warfarin is an anticoagulant medication that increases the risk of bleeding. Contacting the doctor if unusual bleeding or bruising is noticed is essential as it can help prevent serious complications. Choices A, B, and C are incorrect. Using a soft toothbrush is generally recommended for oral hygiene but is not directly related to monitoring for adverse effects of warfarin. Doubling the dose of warfarin if a dose is missed is dangerous and can increase the risk of bleeding. Increasing the intake of leafy green vegetables can interfere with warfarin's effectiveness as they contain vitamin K, which antagonizes warfarin's anticoagulant effects.
5. A client has a new prescription for nitroglycerin. Which of the following instructions should the nurse include?
- A. Store the medication in a cool, dry place.
- B. Take the medication as directed by the healthcare provider.
- C. Take the medication 30 minutes before meals.
- D. Take the medication at the first sign of chest pain.
Correct answer: D
Rationale: Instructing the client to take nitroglycerin at the first sign of chest pain is crucial for immediate relief of angina symptoms. Nitroglycerin is a fast-acting medication that helps dilate blood vessels, improving blood flow to the heart muscle. Therefore, prompt administration at the onset of chest pain is essential to alleviate anginal episodes effectively. Choices A, B, and C are incorrect because storing the medication properly, taking it as directed, or before meals are not specific instructions for managing acute anginal episodes, which require immediate action for symptom relief.
