The healthcare provider prescribes the standard heparin protocol for a client who weighs 95 kg and is diagnosed with a deep vein thrombosis. The loading dose is an IV bolus of 80 units/kg. Heparin is available in vials of 5,000 units/mL. How many mL of heparin should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.5"]
Given:
Ordered loading dose of Heparin: 80 units/kg
Patient weight: 95 kg
Concentration of Heparin: 5,000 units/mL
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 95 kg
Total loading dose (units) = 7600 units
Step 2: Calculate the volume to be administered:
Volume (mL) = Total loading dose (units) / Concentration (units/mL)
Volume (mL) = 7600 units / 5000 units/mL
Volume (mL) = 1.52 mL
Step 3: Round to the nearest tenth:
Volume (mL) ≈ 1.5 mL

Correct Answer is ["8"]
Explanation
Given:
Strength of each tablet: 625 mg
Maximum daily dosage: 5 grams (5000 mg)
Step 1: Calculate the number of tablets:
Number of tablets = Maximum daily dosage (mg) / Strength per tablet (mg/tablet)
Number of tablets = 5000 mg / 625 mg/tablet
Number of tablets = 8 tablets
Correct Answer is ["83"]
Explanation
Given:
Volume of fluid: 2 liters (1 liter = 1000 mL, so 2 liters = 2000 mL)
Infusion time: 24 hours
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 2000 mL / 24 hr
Flow rate (mL/hr) = 83.33 mL/hr
Step 2: Round to the nearest whole number:
Flow rate (mL/hr) ≈ 83 mL/hr
