A nurse is preparing to administer sumatriptan 6 mg subcutaneous to a client. Available is sumatriptan injection 6 mg/0.5 mL. How many mL should the nurse administer? (Round off 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 6 mg of sumatriptan.
Determine the volume per dose:
The sumatriptan injection contains 6 mg per 0.5 mL.
The nurse needs to administer 6 mg per dose.
To find the volume per dose, we can set up a proportion:
6 mg / 0.5 mL = 6 mg / x mL
Cross-multiplying gives us:
6x = 3
Dividing both sides by 6, we get:
x = 0.5 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.
Correct Answer is ["2"]
Explanation
Determine the desired dosage per dose:
The client is prescribed 20 mg of nifedipine three times a day.
The dosage per dose is 20 mg.
Determine the number of capsules per dose:
Each capsule contains 10 mg of nifedipine.
The nurse needs to administer 20 mg per dose.
To find the number of capsules per dose:
10 mg / 1 capsule = 20 mg / x capsules
Cross-multiplying gives us:
10x = 20
Dividing both sides by 10, we get:
x = 2 capsules
