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 ["15"]
Explanation
Step-by-step calculation:
Convert weight to kilograms:
66 lb ÷ 2.2 = 30 kg
Calculate total dose in mg:
25mg/kg × 30 kg = 750 mg
Calculate volume to administer using concentration 50 mg/mL:
750 mg÷50 mg/mL=15 mL.
Round to nearest tenth → 15.0 → per instructions omit trailing zero → 15 mL.
Answer: 15 mL.
Correct Answer is ["0.5"]
Explanation
Determine the desired dosage:
The nurse needs to administer 20 mg of quinapril.
Determine the number of tablets per dose:
Each tablet contains 40 mg of quinapril.
The nurse needs to administer 20 mg per dose.
To find the number of tablets per dose:
40 mg / 1 tablet = 20 mg / x tablets
Cross-multiplying gives us:
40x = 20
Dividing both sides by 40, we get:
x = 0.5 tablets
