A client who weighs 96 kg receives a prescription for heparin 80 units/kg intravenous bolus for the treatment of deep vein thrombosis. How many units should the nurse administer? (Enter numerical value only.)
The Correct Answer is ["7680"]
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

Correct Answer is ["100"]
Explanation
Given:
Volume of fluid: 50 mL
Infusion time: 30 minutes
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Convert infusion time from minutes to hours:
Infusion time (hr) = 30 minutes / 60 minutes/hr
Infusion time (hr) = 0.5 hour
Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 50 mL / 0.5 hr
Flow rate (mL/hr) = 100 mL/hr
Correct Answer is ["2"]
Explanation
Given:
Ordered dose of Fentanyl: 100 mcg
Concentration of Fentanyl: 0.05 mg/mL
Step 1: Convert mcg to mg:
Ordered dose (mg) = Ordered dose (mcg) / 1000 mcg/mg
Ordered dose (mg) = 100 mcg / 1000 mcg/mg
Ordered dose (mg) = 0.1 mg
Step 2: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 3: Substitute the values:
0.1 mg / Volume = 0.05 mg/mL
Step 4: Solve for the unknown volume:
Volume = 0.1 mg / (0.05 mg/mL)
Volume = 0.1 mg x (1 mL / 0.05 mg)
Volume = 2 mL
