A client with deep vein thrombosis (DVT) is receiving a continuous IV infusion of heparin sodium 20,000 units in 5% dextrose injection 500 mL at the rate of 25 mL/hour. How many units of heparin should the client receive in 12 hours? (Enter numeric value only.)
The Correct Answer is ["12000"]
Here's how to calculate the total heparin units the client will receive in 12 hours
Heparin concentration:
The medication is delivered in a 500 mL bag containing 20,000 units of heparin.
Heparin concentration (units/mL) = Total heparin (units) / Volume (mL)
Heparin concentration (units/mL) = 20,000 units / 500 mL
Heparin concentration (units/mL) = 40 units/mL
Infusion rate: 25 mL/hour (given)
Time: 12 hours (given)
We need to find the total number of heparin units delivered in 12 hours.
Total volume delivered in 12 hours:
Volume delivered (mL/hour) x Time (hours) = Total volume delivered (mL)
25 mL/hour x 12 hours = 300 mL
Total heparin units delivered:
Heparin concentration (units/mL) x Total volume delivered (mL) = Total heparin units
40 units/mL x 300 mL = 12,000 units
Therefore, the client will receive 12,000 units of heparin in 12 hours.

Correct Answer is ["2.4"]
Explanation
The vial contains 500 mcg (or 0.5 mg) of digoxin in 2 mL.
This means that each mL contains 0.25 mg of the medication (0.5 mg / 2 mL = 0.25 mg/mL).
The nurse needs to administer 0.6 mg of the medication. To find out how many mL this is, we divide the dose by the concentration:
VolumeinmL = 0.25mg/mL 0.6mg / 0.25mg/mL = 2.4mL
If rounding is required to the nearest tenth, the nurse should administer 2.4 mL of the medication.
Correct Answer is ["1"]
Explanation
First, let’s convert the client’s weight from pounds to kilograms since the dosage is prescribed in mcg/kg.
We know that 1 kg is approximately 2.2 lbs. So,
Weightinkg = 2.2154lbs ≈ 70kg
The prescribed dose is 1.6 mcg/kg.
Therefore, the total dose for this client would be:
Doseinmcg = 1.6mcg/kg×70kg = 112mcg
The medication is available in 112 mcg tablets.
Therefore, to administer a dose of 112 mcg, the nurse should administer 1 tablet
