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 ["6"]
Explanation
Given:
Ordered dose of Oxytocin: 2 milliunits/min
Concentration of Oxytocin: 20 units in 1 liter (1000 mL) = 20 units/1000 mL = 0.02 units/mL
Step 1: Convert milliunits to units:
Ordered dose (units/min) = Ordered dose (milliunits/min) / 1000 milliunits/unit
Ordered dose (units/min) = 2 milliunits/min / 1000 milliunits/unit
Ordered dose (units/min) = 0.002 units/min
Step 2: Calculate the infusion rate in units/hour:
Infusion rate (units/hour) = Ordered dose (units/min) x 60 minutes/hour
Infusion rate (units/hour) = 0.002 units/min x 60 minutes/hour
Infusion rate (units/hour) = 0.12 units/hour
Step 3: Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Infusion rate (units/hour) / Concentration (units/mL)
Infusion rate (mL/hour) = 0.12 units/hour / 0.02 units/mL
Infusion rate (mL/hour) = 6 mL/hour
Correct Answer is ["6.25"]
Explanation
Given:
Ordered dose of erythromycin: 250 mg
Concentration of erythromycin suspension: 200 mg/5 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
250 mg / Volume = 200 mg/5 mL
Step 3: Solve for the unknown volume:
Volume = 250 mg / (200 mg/5 mL)
Volume = 250 mg x (5 mL / 200 mg)
Volume = 6.25 mL
