1. A client with increased liver enzymes is taking herbal supplements. Which of the following herbal supplements should the nurse report to the provider?
- A. Glucosamine
- B. Saw palmetto
- C. Kava
- D. St. John's wort
Correct answer: C
Rationale: Chronic use or high doses of kava have been associated with liver damage, including severe liver failure. Therefore, the nurse should report the client's use of kava to the healthcare provider for further evaluation and management.
2. A client in a long-term care facility has Hypothyroidism and a new prescription for Levothyroxine. Which of the following dosage schedules should the nurse expect for this client?
- A. The client will start at a high dose, and the dose will be tapered as needed.
- B. The client will remain on the initial dosage during the course of treatment.
- C. The client's dosage will be adjusted daily based on blood levels.
- D. The client will start on a low dose, which will be gradually increased.
Correct answer: D
Rationale: The nurse should expect that levothyroxine will be started at a low dose and gradually increased over several weeks. This cautious approach is crucial, especially in older adult clients, to prevent toxicity and ensure optimal therapeutic outcomes for managing hypothyroidism. Choice A is incorrect because starting at a high dose and tapering as needed is not the standard approach for levothyroxine. Choice B is incorrect because the initial dosage is typically adjusted to reach the optimal therapeutic dose. Choice C is incorrect as adjusting the dosage daily based on blood levels is not necessary for levothyroxine, as it has a long half-life and requires time to reach a steady state.
3. A client has been prescribed Aspirin for prevention of cardiovascular disease. Which of the following findings indicates the medication is effective?
- A. The client has a decrease in troponin levels.
- B. The client has a regular heart rhythm.
- C. The client experiences a decrease in episodes of angina.
- D. The client's blood pressure remains stable.
Correct answer: C
Rationale: The correct answer is C. A decrease in episodes of angina indicates that Aspirin is effectively preventing the formation of clots that could lead to cardiovascular events. Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle, usually due to coronary artery disease. Aspirin works by inhibiting platelet aggregation, thereby reducing the risk of clot formation in the arteries. Improvement in angina symptoms suggests that the medication is successfully preventing clot-related complications in the cardiovascular system. Monitoring and recognizing a decrease in angina episodes can be a valuable indicator of the medication's efficacy in preventing cardiovascular events. Choices A, B, and D are incorrect because a decrease in troponin levels, a regular heart rhythm, or stable blood pressure, while important parameters, do not directly reflect the effectiveness of Aspirin in preventing cardiovascular events through antiplatelet action.
4. While caring for a client receiving epoetin alfa to treat anemia, which finding should the nurse monitor for?
- A. Leukocytosis
- B. Hypertension
- C. Hyperkalemia
- D. Fever
Correct answer: B
Rationale: The nurse should monitor the client for hypertension when receiving epoetin alfa. Epoetin alfa stimulates red blood cell production, which can lead to increased blood pressure. Leukocytosis (increased white blood cells) and hyperkalemia (high potassium levels) are not typically associated with epoetin alfa therapy. Fever is also not a common adverse effect of this medication.
5. A client with chronic myeloid leukemia is receiving hydroxyurea. Which of the following findings should the nurse monitor?
- A. Hyperkalemia
- B. Hypertension
- C. Neutropenia
- D. Tinnitus
Correct answer: C
Rationale: The nurse should monitor the client for neutropenia when receiving hydroxyurea. Neutropenia is a common adverse effect caused by bone marrow suppression. It is essential to assess the client's white blood cell count regularly to detect neutropenia early and prevent complications such as infections.
