The nurse is preparing to deliver 2.5 mcg/kg/min of nitroprusside. The client weighs 154 pounds. Available is 50 mg of nitroprusside in 250 ml DSW. How many mL/hr will the nurse program the pump to deliver? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Rationale: Step 1: Convert weight from pounds to kilograms: 154 lb ÷ 2.2 ≈ 70 kg Step 2: Calculate dose in mcg/min: 2.5 mcg/kg/min × 70 kg = 175 mcg/min Step 3: Convert available solution to mcg/mL: 50 mg = 50,000 mcg in 250 mL → 50,000 ÷ 250 = 200 mcg/mL Step 4: Calculate mL/min: 175 mcg/min ÷ 200 mcg/mL ≈ 0.875 mL/min Step 5: Convert to mL/hr: 0.875 mL/min × 60 min/hr = 52.5 mL/hr Final Answer: 52.5 mL/hr
