1. A healthcare professional is reviewing laboratory results for a client who is receiving heparin via continuous IV infusion. Which of the following results indicates that the heparin infusion should be increased?
- A. aPTT of 90 seconds
- B. Platelet count of 150,000/mm³
- C. INR of 1.0
- D. Hgb of 15 g/dL
Correct answer: A
Rationale: An aPTT of 90 seconds is above the therapeutic range for heparin, which typically falls between 60-80 seconds. This indicates that the current heparin dose is too high, and the infusion rate should be decreased to avoid excessive anticoagulation and the risk of bleeding. Monitoring aPTT is crucial in adjusting heparin therapy to maintain it within the therapeutic range.
2. A client has a new prescription for Enfuvirtide to treat HIV infection. The nurse should monitor the client for which of the following adverse reactions?
- A. Bone marrow suppression
- B. Pancreatitis
- C. Pancreatitis
- D. Bone marrow suppression
Correct answer: D
Rationale: While bone marrow suppression is not typically associated with Enfuvirtide, a more relevant concern is the risk of severe allergic reactions such as anaphylaxis. Enfuvirtide, an HIV fusion inhibitor, can cause local injection site reactions and systemic allergic responses. Monitoring for signs of allergic reactions, such as rash, fever, and difficulty breathing, is crucial to ensure the client's safety.
3. A healthcare provider is reviewing a client's health record and notes that the client is experiencing episodes of hypokalemia. Which of the following medications should the healthcare provider identify as a cause of the client's hypokalemia?
- A. Captopril
- B. Lisinopril
- C. Furosemide
- D. Spironolactone
Correct answer: C
Rationale: Furosemide is a loop diuretic that acts on the kidneys to increase urine production. This increased urine output can lead to the excessive excretion of potassium, resulting in hypokalemia. Monitoring potassium levels and considering supplementation may be necessary when a patient is on furosemide to prevent or manage hypokalemia.
4. A client is receiving treatment with methotrexate. Which of the following supplements should the nurse instruct the client to take?
- A. Folic acid
- B. Vitamin D
- C. Calcium
- D. Iron
Correct answer: A
Rationale: The nurse should instruct the client to take folic acid when receiving treatment with methotrexate to reduce the risk of methotrexate toxicity. Methotrexate acts as a folic acid antagonist, leading to folic acid deficiency, which can be counteracted by supplementing with folic acid. Vitamin D, calcium, and iron are not specifically recommended to counteract methotrexate effects and do not play a significant role in mitigating methotrexate toxicity.
5. A client in an outpatient facility is taking Acarbose for type 2 Diabetes Mellitus. Which of the following laboratory tests should the nurse plan to monitor?
- A. WBC
- B. Serum potassium
- C. Platelet count
- D. Liver function test
Correct answer: D
Rationale: The correct answer is D: Liver function test. Acarbose, used for type 2 Diabetes Mellitus, can lead to liver toxicity with long-term use. Monitoring liver function tests periodically is crucial to detect any signs of liver dysfunction early and prevent complications. Choices A, B, and C are incorrect as Acarbose does not directly affect WBC, serum potassium, or platelet count levels.
