A nurse is preparing to administer propranolol 240 mg/day PO in two divided doses to a client. Available is propranolol 60 mg tablets. How many tablets should the nurse administer with each 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 ["2"]
Understanding the Problem
Order: Propranolol 240 mg/day PO in two divided doses
Available: Propranolol 60 mg tablets
Desired Dose: Number of tablets per dose
Step 1: Calculate the Dose per Administration
Total Daily Dose: 240 mg
Number of Doses: 2
Dose per Administration: 240 mg / 2 doses = 120 mg/dose
Step 2: Calculate the Number of Tablets per Dose
Dose per Administration: 120 mg
Tablet Strength: 60 mg/tablet
Number of Tablets: 120 mg / 60 mg/tablet = 2 tablets
Step 3: Round to the Nearest Whole Number
The calculated number of tablets is 2, which is already a whole number.
Answer: 2 tablets

Explanation
Order: Dopamine 2 mcg/kg/min
Client Weight: 176 lbs
Available Solution: Dopamine 400 mg in 250 mL of D5W
Desired Rate: mL/hr
Convert Client Weight to Kilograms (kg)
1 kg = 2.2 lbs
Client Weight in kg: 176 lbs / 2.2 lbs/kg = 80 kg
Step 2: Calculate the Dopamine Dose per Minute
Dose: 2 mcg/kg/min
Client Weight: 80 kg
Total Dose per Minute: 2 mcg/kg/min x 80 kg = 160 mcg/min
Step 3: Convert Dopamine Dose to Milligrams (mg)
1 mg = 1000 mcg
Dose in mg/min: 160 mcg/min / 1000 mcg/mg = 0.16 mg/min
Step 4:Calculate the Dopamine Dose per Hour
Dose in mg/min: 0.16 mg/min
Minutes in an Hour: 60 min
Dose in mg/hr: 0.16 mg/min x 60 min/hr = 9.6 mg/hr
Step 5: Determine the Concentration of the Dopamine Solution
Available Dopamine: 400 mg
Solution Volume: 250 mL
Concentration: 400 mg / 250 mL = 1.6 mg/mL
Step 6: Calculate the Infusion Rate in mL/hr
Dose in mg/hr: 9.6 mg/hr
Concentration: 1.6 mg/mL
Infusion Rate: 9.6 mg/hr / 1.6 mg/mL = 6 mL/hr
Step 7: Round to the Nearest Whole Number
The calculated rate is 6 mL/hr, which is already a whole number.
Answer: 6 mL/hr
Correct Answer is C
Explanation
A. A total 62.5 mL is available in this dose: The label states that each mL of the reconstituted solution contains 62.5 mg of methylprednisolone. However, the total volume available depends on the reconstitution process, and this option does not directly match the provided information.
B. This medication can be administered IM only: The label clearly states that the medication can be given both intramuscularly (IM) and intravenously (IV), making this option incorrect.
C. This medication should be protected from light: The label explicitly instructs to protect the medication from light, confirming this as the correct answer.
D. The medication is effective for 7 days after reconstitution: The label specifies that the medication should be used within 48 hours after reconstitution, not 7 days.
