A nurse is preparing to administer lisinopril 2.5 mg PO to an older adult client. Available is lisinopril 5 mg tablets. How many tablets should the nurse administer? (Round 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"]
To calculate how many tablets of lisinopril 5 mg the nurse should administer to achieve a 2.5 mg dose, divide the desired dose by the dose per tablet:
Number of tablets = Desired dose / Dose per tablet
Number of tablets = 2.5 mg / 5 mg/tablet
Number of tablets = 0.5 tablets

Correct Answer is ["83"]
Explanation
To calculate the manual IV flow rate in drops per minute (gtt/min), you can use the following formula:
Flow rate (gtt/min) = (Volume to be infused in mL / Time in minutes) * Drop factor (gtt/mL)
Given:
- Volume to be infused = 250 mL
- Time in minutes = 30 minutes
- Drop factor = 10 gtt/mL
Now, plug these values into the formula:
Flow rate (gtt/min) = (250 mL / 30 min) * 10 gtt/mL
Flow rate (gtt/min) = (8.33) * 10
Flow rate (gtt/min) ≈ 83.3
Rounded to the nearest whole number, the nurse should set the manual IV flow rate to deliver approximately 83 gtt/min.
Correct Answer is ["0.4"]
Explanation
To calculate the mL of enoxaparin to administer, you can use the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
In this case, the dose is 40 mg, and the concentration is 100 mg/mL:
Volume (mL) = 40 mg / 100 mg/mL = 0.4 mL
So, the nurse should administer 0.4 mL of enoxaparin.
