1. A client receiving chemotherapy with Methotrexate asks why Leucovorin is being given. Which of the following responses should the nurse use?
- A. Leucovorin reduces the risk of a transfusion reaction from Methotrexate.
- B. Leucovorin increases platelet production and prevents bleeding.
- C. Leucovorin potentiates the cytotoxic effects of Methotrexate.
- D. Leucovorin protects healthy cells from Methotrexate's toxic effects.
Correct answer: D
Rationale: Leucovorin, a folic acid derivative and an antagonist to Methotrexate, is given within 12 hours of high doses of Methotrexate to protect healthy cells from the toxic effects of Methotrexate. It helps to reduce the bone marrow suppression and gastrointestinal side effects caused by Methotrexate, supporting the client's overall well-being during chemotherapy treatment. Choices A, B, and C are incorrect because Leucovorin does not reduce the risk of a transfusion reaction from Methotrexate, increase platelet production, prevent bleeding, or potentiate the cytotoxic effects of Methotrexate. Instead, Leucovorin works by rescuing healthy cells from the toxic effects of Methotrexate.
2. What is the classification for the drug valproate?
- A. Anti-diabetic
- B. Anti-convulsant
- C. Anti-ulcer agent
- D. Anti-hypertensive
Correct answer: B
Rationale: Valproate is classified as an anticonvulsant. It is commonly used to treat epilepsy and bipolar disorder by stabilizing electrical activity in the brain. Therefore, the correct classification for valproate is as an anticonvulsant. Options A, C, and D are incorrect because valproate is not used to treat diabetes, ulcers, or hypertension.
3. A client is starting therapy with bicalutamide. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Muscle pain
- B. Flushing
- C. Gynecomastia
- D. Hyperglycemia
Correct answer: C
Rationale: The correct answer is gynecomastia (Choice C). Bicalutamide is associated with gynecomastia due to its antiandrogenic properties. Gynecomastia, the development of breast tissue in males, is an important adverse effect to monitor when taking bicalutamide. Choices A, B, and D are incorrect. Muscle pain and flushing are not commonly associated with bicalutamide use. Hyperglycemia is not a typical adverse effect of bicalutamide therapy.
4. A client has a new prescription for Clopidogrel. Which of the following instructions should the nurse include?
- A. Avoid taking aspirin while on this medication.
- B. Take this medication with food.
- C. Avoid eating foods high in potassium.
- D. Take this medication at bedtime.
Correct answer: A
Rationale: The correct answer is to instruct the client to avoid taking aspirin while on Clopidogrel. Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Aspirin and other NSAIDs can further potentiate this risk, so they should be avoided while taking Clopidogrel to reduce the chance of bleeding complications. Choices B, C, and D are incorrect. There is no specific instruction to take Clopidogrel with food or at bedtime. Avoiding foods high in potassium is not directly related to Clopidogrel use.
5. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?
- A. Lowered heart rate
- B. Increased myocardial contractility
- C. Decreased conduction through the AV node
- D. Vasoconstriction of renal blood vessels
Correct answer: B
Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.
