A nurse is preparing to administer dopamine 5 mcg/kg/min via continuous IV infusion to a newborn who weighs 4.4 kg and has septic shock. Available in dopamine 200 mg in dextrose 5% in water 250 mL. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.7"]
The dose of dopamine in mg/hr: 5 mcg/kg/min x 4.4 kg x 60 min/hr = 1320 mcg/hr Converted to mg: 1320 mcg/hr / 1000 mcg/mg = 1.32 mg/hr
Infusion rate in mL/hr: 1.32 mg/hr / (200 mg/250 mL) = 1.65 mL/hr Rounded off to the nearest tenth: 1.7 mL/hr

Correct Answer is ["6.7"]
Explanation
The question is asking for the volume of ferrous sulfate syrup that the nurse should administer per dose. The desired dose is 120 mg and the available syrup has a concentration of 90 mg/5 mL.
Let’s calculate this step by step:
Step 1: Identify the desired dose, which is 120 mg.
Step 2: Identify the concentration of the available medication, which is 90 mg/5 mL.
Step 3: Set up the equation to solve for the volume (V) in mL. The equation is (Desired dose ÷ Concentration) × Volume of the concentration = V.
Step 4: Substitute the known values into the equation: (120 mg ÷ 90 mg) × 5 mL = V.
Step 5: Solve the equation: V = (1.33) × 5 mL = 6.67 mL.
So, the nurse should administer approximately 6.7 mL of the ferrous sulfate syrup per dose.
Correct Answer is ["0.5"]
Explanation
Dose / Concentration = Volume Plug in the values from the question:
10 mg / 20 mg/ml = 0.5 ml
Round the answer to the nearest tenth:
=0.5 ml
