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

Correct Answer is C
Explanation
A. The medication can be used for up to 14 days after reconstitution: The label states that the reconstituted solution should be used within 48 hours and discarded afterward, making this option incorrect.
B. The medication should be reconstituted with 0.9% sodium chloride solution: The label specifies that the medication should be reconstituted with bacteriostatic water for injection USP with benzyl alcohol, not 0.9% sodium chloride solution.
C. The medication can be used for IV administration: The label states that the medication is for intramuscular (IM) or intravenous (IV) use, confirming that IV administration is appropriate.
D. The vial contains a single dose: The label indicates that this is a multiple-dose vial, meaning it can be used for more than one administration.
Correct Answer is ["25"]
Explanation
Identify the Given Information:
Infusion Rate: 100 mL/hr
Drop Factor: 15 gtt/mL
Convert the Infusion Rate to mL/min:
There are 60 minutes in 1 hour.
Infusion Rate (mL/min) = 100 mL/hr / 60 min/hr
Infusion Rate (mL/min) = 1.6667 mL/min (approximately)
Calculate the Drip Rate (gtt/min):
Drip Rate (gtt/min) = Infusion Rate (mL/min) x Drop Factor (gtt/mL)
Drip Rate (gtt/min) = 1.6667 mL/min x 15 gtt/mL
Drip Rate (gtt/min) = 25 gtt/min
Round to the Nearest Whole Number (if necessary):
25 gtt/min
