Correct Answer is ["2500"]
Explanation
Step 1: Convert liters to milliliters.
1 liter is equal to 1000 milliliters. Therefore, we can convert 2.5 liters to milliliters as follows:
2.5 liters * 1000 milliliters/liter = 2500 milliliters
Step 2: Round the answer to the nearest whole number.
The answer is 2500 milliliters. Since we are instructed to round to the nearest whole number, we do not need to make any changes.
Therefore, the nurse should administer 2500 mL of lactated Ringer's to the client.
Correct Answer is ["1.7"]
Explanation
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
