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 ["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.
Correct Answer is ["10"]
Explanation
To calculate the volume in milliliters (mL) of amoxicillin oral suspension needed to administer 775 mg, you can use the following formula:
Volume (mL) = (Desired dose in mg / Concentration in mg/mL)
Given:
- Desired dose = 775 mg
- Concentration = 400 mg/5 mL
First, calculate the concentration in mg/mL by dividing 400 mg by 5 mL:
Concentration = 400 mg / 5 mL = 80 mg/mL
Now, use the formula to calculate the volume in mL:
Volume (mL) = (775 mg / 80 mg/mL)
Volume (mL) ≈ 9.69 mL
Rounded to the nearest whole number, the nurse should administer approximately 10 mL of amoxicillin oral suspension to provide a dose of 775 mg.
