A client is to receive 10 mcg/min nitroglycerine IV. The concentration of solution is 50 mg in 250 mL DSW. At what rate (mL/hr) will the nurse set the pump? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Rationale: Step 1: Convert available solution to mcg/mL: 50 mg = 50,000 mcg in 250 mL → 50,000 ÷ 250 = 200 mcg/mL Step 2: Calculate mL/min to deliver 10 mcg/min: 10 mcg/min ÷ 200 mcg/mL = 0.05 mL/min Step 3: Convert to mL/hr: 0.05 mL/min × 60 min/hr = 3.0 mL/hr Final Answer: 3 mL/hr
