The healthcare provider prescribes dopamine 2 mcg/kg/min intravenously (IV) for client who weighs 60 kg. The IV bag contains dopamine 200 mg in dextrose 5% in water (DW) 250 mL. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numerical value only.)
The Correct Answer is ["9"]
Here are the steps you can follow to calculate the infusion pump flow rate:
Step 1: Calculate the prescribed dose in mcg/min
- Dose per weight: 2 mcg/kg/min * 60 kg = 120 mcg/min
Step 2: Convert the concentration in the IV bag to mcg/mL
- Convert mg to mcg: 200 mg * 1000 mcg/mg = 200,000 mcg
- Concentration: 200,000 mcg / 250 mL = 800 mcg/mL
Step 3: Calculate the flow rate in mL/min
- Flow rate: 120 mcg/min / 800 mcg/mL = 0.15 mL/min
Step 4: Convert the flow rate to mL/hour
- Hour conversion: 0.15 mL/min * 60 min/hour = 9 mL/hour
Therefore, the nurse should program the infusion pump to deliver 9 mL/hour.

Explanation
less than body requirements would be the nursing problem with the highest priority for an adolescent with anorexia nervosa. Anorexia nervosa is characterized by a severe restriction of food intake leading to a significantly low body weight, which can have serious physical and psychological consequences. Therefore, addressing the client's malnutrition and promoting adequate nutrition intake is crucial to prevent further complications.
Disturbed Body Image, Interrupted Family Processes, and Noncompliance with treatment regimen are important nursing problems to address, but they are secondary to the client's malnutrition.
