A client is admitted from the emergency department with diabetic ketoacidosis. A bolus of 0.1 units/kg regular insulin is prescribed. The client weighs 200 pounds. How many units of insulin should the nurse administer? (Enter numeric value only. Round to the nearest whole number.)
The Correct Answer is ["9"]
Given:
Ordered dose of insulin: 0.1 units/kg
Patient weight: 200 pounds
Step 1: Convert patient weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Patient weight in kg = 200 lbs x 0.453592 kg/lb = 90.718 kg
Step 2: Calculate the total dose of insulin:
Total dose (units) = Ordered dose (units/kg) x Patient weight (kg)
Total dose (units) = 0.1 units/kg x 90.718 kg
Total dose (units) = 9.0718 units
Step 3: Round to the nearest whole number:
Total dose (units) ≈ 9 units

Correct Answer is ["7"]
Explanation
Given:
Ordered dose of Nesiritide: 0.01 mcg/kg/minute
Patient weight: 155.1 pounds
Bag size: 250 mL D5W
Concentration of Nesiritide: 1.5 mg
Step 1: Convert patient weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Patient weight in kg = 155.1 lbs x 0.453592 kg/lb = 70.3 kg
Step 2: Calculate the total dose of Nesiritide in mcg/minute:
Total dose (mcg/minute) = Ordered dose (mcg/kg/minute) x Patient weight (kg)
Total dose (mcg/minute) = 0.01 mcg/kg/minute x 70.3 kg
Total dose (mcg/minute) = 0.703 mcg/minute
Step 3: Convert mcg/minute to mg/hour:
Total dose (mg/hour) = Total dose (mcg/minute) x 60 minutes/hour / 1000 mcg/mg
Total dose (mg/hour) = 0.703 mcg/minute x 60 minutes/hour / 1000 mcg/mg
Total dose (mg/hour) = 0.04218 mg/hour
Step 4: Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Total dose (mg/hour) / Concentration (mg/mL)
Infusion rate (mL/hour) = 0.04218 mg/hour / (1.5 mg/250 mL)
Infusion rate (mL/hour) = 0.04218 mg/hour x (250 mL/1.5 mg)
Infusion rate (mL/hour) = 7.03 mL/hour
Step 5: Round to the nearest whole number:
Infusion rate (mL/hour) ≈ 7 mL/hour
Correct Answer is ["7680"]
Explanation
Given:
Ordered loading dose of Heparin: 80 units/kg
Patient weight: 96 kg
Step 1: Calculate the total loading dose of Heparin:
Total loading dose (units) = Ordered dose (units/kg) x Patient weight (kg)
Total loading dose (units) = 80 units/kg x 96 kg
Total loading dose (units) = 7680 units
