A nurse is preparing to administer heparin 8,000 units subcutaneous to a client. Available is heparin injection 10,000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8 "]
Given:
- Desired dose of heparin: 8,000 units
- Available strength of heparin injection: 10,000 units/mL
First, find out how many milliliters of heparin correspond to the desired dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 8,000 units / 10,000 units/mL Volume (mL) = 0.8 mL
So, the nurse should administer 0.8 mL of heparin.

Correct Answer is ["1.8"]
Explanation
Given:
- Desired dose of gentamicin: 1 mg/kg
- Client's weight: 154 lb
- Available strength of gentamicin solution: 40 mg/mL
First, convert the client's weight from pounds to kilograms:
154 lb ÷ 2.2= 70kg
Now, calculate the desired dose of gentamicin:
Desired dose = Dosage per kg × Weight Desired dose = 1 mg/kg × 670 kg Desired dose = 70 mg
Now, find out how many milliliters of gentamicin correspond to this dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 70 mg / 40 mg/mL Volume (mL) ≈ 1.75mL
rounded off to the nearest tenths= 1.8ml
Correct Answer is ["1.9"]
Explanation
Desired dose of isoniazid: 187 mg
Available strength of isoniazid injection: 100 mg/mL
First, find out how many milliliters of isoniazid correspond to the desired dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 187 mg / 100 mg/mL
Volume (mL) = 1.87 mL
Rounded off to the nearest tenth = 1.9 ml
