Question 1 of 5
The nurse is administering subcutaneous enoxaparin to a client following knee replacement surgery to prevent a deep vein thrombosis. Which laboratory result requires immediate action by the nurse? Which laboratory result requires immediate action by the nurse?
Correct Answer: B
Rationale: A platelet count of 100,000/mm3 indicates thrombocytopenia, increasing bleeding risk with enoxaparin, an anticoagulant. Immediate action, such as notifying the provider, is needed to prevent hemorrhage.
Question 2 of 5
Before administering the initial dose of sumatriptan succinate to a client with a migraine headache, it is most important to determine if the client's history includes which problem? Which problem in the client's history is most important to determine?
Correct Answer: B
Rationale: Sumatriptan, a triptan, causes vasoconstriction, which can precipitate myocardial ischemia in clients with coronary artery disease. Checking for this condition prevents serious cardiovascular events.
Question 3 of 5
Before administering a laxative to a bedfast client, it is most important for the nurse to perform which assessment? Which assessment is most important for the nurse to perform?
Correct Answer: B
Rationale: Assessing the frequency and consistency of bowel movements provides critical information about the client's bowel function, establishing a baseline to determine the need for a laxative and evaluate its effectiveness. This helps avoid overmedication or complications like diarrhea or fecal impaction, making it the most important assessment before administering a laxative.
Question 4 of 5
A client with narcolepsy receives a new prescription for methylphenidate. Prior to administration of the medication, the nurse should review the medical record for which condition? Which condition should the nurse review the medical record for?
Correct Answer: C
Rationale: Methylphenidate, a stimulant, can increase blood pressure and heart rate, exacerbating hypertension. Reviewing the medical record for hypertension ensures safe administration and prevents cardiovascular complications.

A client with bulimia and depression who is taking phenelzine 90 mg daily is admitted to an acute care hospital for uncontrolled hypertension. Which dietary choices should the nurse instruct the client to avoid? Which dietary choices should the nurse instruct the client to avoid?
