A nurse is preparing to administer calcium citrate 1.9 g PO. Available is calcium citrate 950 mg tablets. How many tablets should the nurse administer? (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 "]
Given:
- Desired dose of calcium citrate: 1.9 g
- Available strength of calcium citrate tablets: 950 mg
First, convert the desired dose from grams to milligrams: 1.9 g = 1900 mg
Now, let's find out how many tablets are needed:
Number of tablets = Desired dose / Strength per tablet
Number of tablets = 1900 mg / 950 mg/tablet Number of tablets = 2 tablets
So, the nurse should administer approximately 2 tablets of calcium citrate.

Explanation
Given:
- Insulin glargine concentration: 100 units/mL
- Total volume of insulin in the vial: 10 mL
- Dose of insulin glargine per day: 10 units
Calculation:
First, let's find out how many total units are in the vial:
Total units = Concentration (units/mL) × Volume (mL) Total units = 100 units/mL × 10 mL
Total units = 1000 units
Now, let's find out how many doses can be obtained from the total units in the vial: Number of doses = Total units / Dose per day
Number of doses = 1000 units / 10 units/day Number of doses = 100 doses
So, the vial contains approximately 100 doses of insulin glargine.
Correct Answer is ["2"]
Explanation
Given:
- Desired dose of ibuprofen: 200 mg
- Available strength of ibuprofen oral suspension: 100 mg/5 mL
First, find out the concentration of ibuprofen in mg/mL:
Concentration = 100 mg / 5 mL Concentration = 20 mg/mL
Now, calculate how many milliliters (mL) of ibuprofen oral suspension are needed to achieve the desired dose:
Volume (mL) = Desired dose / Concentration Volume (mL) = 200 mg / 20 mg/mL
Volume (mL) = 10 mL
Since 1 teaspoon (tsp) is approximately 5 milliliters (mL), the nurse should instruct the client to take:
Number of teaspoons = Volume (mL) / 5 mL per tsp Number of teaspoons = 10 mL / 5 mL per tsp Number of teaspoons = 2 tsp
So, the nurse should instruct the client to take 2 teaspoons of ibuprofen oral suspension.
