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 ["38"]
Explanation
Identify the Given Information:
Infusion Rate: 150 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) = 150 mL/hr / 60 min/hr
Infusion Rate (mL/min) = 2.5 mL/min
Calculate the Drip Rate (gtt/min):
Drip Rate (gtt/min) = Infusion Rate (mL/min) x Drop Factor (gtt/mL)
Drip Rate (gtt/min) = 2.5 mL/min x 15 gtt/mL
Drip Rate (gtt/min) = 37.5 gtt/min
Round to the Nearest Whole Number:
38 gtt/min
Correct Answer is ["3"]
Explanation
Understanding the Problem
Order: Metoclopramide 15 mg IV
Available Solution: Metoclopramide 5 mg/mL
Desired Dose: mL to administer
Step 1: Set Up the Calculation
We need to find the volume (in mL) that contains the ordered dose (15 mg). We can do this by dividing the ordered dose by the concentration of the available solution:
Volume (mL) = Ordered Dose (mg) / Concentration (mg/mL)
Step 2: Perform the Calculation
Ordered Dose: 15 mg
Concentration: 5 mg/mL
Volume: 15 mg / 5 mg/mL = 3 mL
Step 3: Round to the Nearest Whole Number
The result is 3 mL, which is already a whole number.
Answer: 3 mL
