Question 1 of 5
When administering enoxaparin (Lovenox) to a client for DVT prophylaxis, what is the most important lab value to monitor?
Correct Answer: A
Rationale: The correct answer is A: Platelet count. When administering enoxaparin for DVT prophylaxis, monitoring platelet count is crucial because enoxaparin can cause thrombocytopenia. Decreased platelet count can increase the risk of bleeding. Monitoring PT/INR and aPTT is more relevant for monitoring warfarin or heparin therapy, not enoxaparin. Hemoglobin monitoring is important for assessing anemia but not specifically related to enoxaparin administration for DVT prophylaxis.
Question 2 of 5
The client on a beta blocker has a blood pressure of 88/58 mm Hg. What is the nurse's priority action?
Correct Answer: A
Rationale: The correct answer is A: Hold the beta blocker and notify the healthcare provider. A blood pressure of 88/58 mm Hg is considered hypotension, which can be a serious side effect of beta blockers. By holding the medication and notifying the healthcare provider, the nurse ensures prompt assessment and appropriate intervention. Administering the beta blocker (B) could further lower the blood pressure. Increasing the dose (C) would exacerbate the hypotension. Continuing to monitor and reassess (D) is not sufficient as immediate action is required due to the low blood pressure reading.
