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 ["0.6"]
Explanation
Determine the desired dosage:
The nurse needs to administer 3 mg of haloperidol.
Determine the volume per dose:
The haloperidol injection contains 5 mg per 1 mL.
The nurse needs to administer 3 mg per dose.
To find the volume per dose:
5 mg / 1 mL = 3 mg / x mL
Cross-multiplying gives us:
5x = 3
Dividing both sides by 5, we get:
x = 0.6 mL
Correct Answer is ["0.5"]
Explanation
Determine the desired dosage:
The nurse needs to administer 100 mg of amoxicillin.
Determine the volume per dose:
The amoxicillin suspension contains 200 mg per 5 mL.
The nurse needs to administer 100 mg per dose.
To find the volume per dose:
200 mg / 5 mL = 100 mg / x mL
Cross-multiplying gives us:
200x = 500
Dividing both sides by 200, we get:
x = 2.5 mL
Convert mL to tsp:
There are approximately 5 mL in 1 teaspoon (tsp).
So, 2.5 mL is equal to 2.5 mL / 5 mL/tsp = 0.5 tsp.
