A nurse is reviewing a new prescription for propranolol 200 mg PO daily divided in equal doses every 12 hr for a client who has migraine headaches during the premenstrual period. Available is propranolol solution 4 mg/mL. How many mL should the client self-administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["25"]
mL = mg / 4 mL = 100 / 4
mL = 25 / 1
This means that the client needs to take 25 mL of the propranolol solution every 12 hours to get the prescribed dose of 200 mg per day

Correct Answer is ["1"]
Explanation
Dosage (mL) = Ordered dose (mg) / Available dose (mg/mL) Therefore;
Dosage = 150 mg / 150 mg/mL Dosage = 1 mL
Therefore, the nurse should administer 1 mL of medroxyprogesterone solution for injection to the client.
Correct Answer is ["75"]
Explanation
Step 1: Identify the amount of formula in ounces. Result: 2.5 oz
Step 2: Convert ounces to milliliters using the conversion factor 1 ounce = 30 mL. Calculation: 2.5 oz × 30 mL/oz Result: 2.5 × 30 = 75 mL
Step 3: Round the result to the nearest whole number. Result: 75 mL (no rounding needed)
The nurse should document 75 mL as the intake on the I&O record.
