Correct Answer: 32 mL
Rationale: mL/hr = (1600 units/hr x 500 mL) / 25,000 units = 32 mL/hr.

A nurse is caring for a client who is postoperative hip arthroplasty and has a new prescription for enoxaparin 1 mg/kg/dose subcutaneous every 12 hr. The client weighs 95 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 43.2 mg

Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 33 gtt/min
Rationale: gtt/min = (100 mL x 10 gtt/mL) / 30 min = 33.33, rounded to 33.
