A nurse is preparing to administer quinapril 20 mg PO. Available is quinapril 40 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 find the number of tablets,
we divide the total dosage in mg by the strength of each tablet in mg.
Let’s do the calculation:
Number of tablets=Strength of each tablet in mgTotal dosage in mg=40 mg/tablet20 mg=0.5 tablet
So, the nurse should administer 0.5 tablet of quinapril.

Correct Answer is ["100"]
Explanation
the nurse can calculate the volume of vancomycin to administer for the intermittent IV bolus using the available information:
1. Reconstituted Concentration: The nurse reconstitutes the vancomycin powder to a final concentration of 5 mg/mL.
2. Desired Dose: The client needs to receive 500 mg of vancomycin.
3. Volume Calculation: We can find the volume to administer using the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
4. Plugging in the values:
Volume (mL) = 500 mg / 5 mg/mL
5. Rounding the answer: The calculated volume is 100 mL. Round to the nearest whole number for medication administration:
Volume (mL) = 100 mL (rounded)
Therefore, the nurse should administer 100 mL of the reconstituted vancomycin solution.
Correct Answer is ["100"]
Explanation
The label on the vial indicates that the insulin glargine has a concentration of 100 units per milliliter (U-100) and the total volume of the vial is 10 mL.
To calculate the total number of units in the vial, you multiply the volume by the concentration:
Total units = Volume × Concentration = 10 mL×100 units/mL = 1000 units
Then, to find out how many doses of 10 units each are in the vial,
you divide the total number of units by the number of units per dose:
Number of doses = Total units/ Units per dose
= 1000 units /10 units per dose
= 100 doses
So, the vial contains 100 doses of this medication when administered at 10 units per dose
