A nurse preparing to administer heparin 10,000 units subcutaneous every 8 hr. Available i heparin injection 20,000 units/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
Determine the desired dosage:
The nurse needs to administer 10,000 units of heparin.
Determine the volume per dose:
The heparin injection contains 20,000 units per 1 mL.
The nurse needs to administer 10,000 units per dose.
To find the volume per dose:
20,000 units / 1 mL = 10,000 units / x mL
Cross-multiplying gives us:
20,000x = 10,000
Dividing both sides by 20,000, we get:
x = 0.5 mL

Correct Answer is ["2.5"]
Explanation
Determine the desired dosage:
The nurse needs to administer 125 mg of valproic acid.
Determine the volume per dose:
The valproic acid syrup contains 250 mg per 5 mL.
The nurse needs to administer 125 mg per dose.
To find the volume per dose:
250 mg / 5 mL = 125 mg / x mL
Cross-multiplying gives us:
250x = 625
Dividing both sides by 250, we get:
x = 2.5 mL
Correct Answer is ["1.1"]
Explanation
Determine the desired dosage:
The nurse needs to administer 250 mg of cefazolin.
Determine the volume per dose:
The concentration of the reconstituted cefazolin solution is 225 mg/mL.
The nurse needs to administer 250 mg per dose.
To find the volume per dose:
225 mg / 1 mL = 250 mg / x mL
Cross-multiplying gives us:
225x = 250
Dividing both sides by 225, we get:
x = 1.111 mL
Round the answer to the nearest tenth:
Rounding 1.111 to the nearest tenth gives us 1.1 mL.
