A nurse is preparing to administer midazolam 7 mg IM 30 min prior to a procedure. Available is midazolam injection 5 mg/mL. How many mL 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 ["1.4 "]
Given:
- Desired dose of midazolam: 7 mg
- Available strength of midazolam injection: 5 mg/mL
The milliliters of midazolam correspond to the desired dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 7 mg / 5 mg/mL
Volume (mL) = 1.4 mL
So, the nurse should administer approximately 1.4 mL of midazolam.

Correct Answer is ["100 "]
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 ["2.7 "]
Explanation
Volume (mL) = Desired dose / Concentration
Volume (mL) = 750 mg / 280 mg/mL
Volume (mL) rounded off to the nearest tenth ≈ 2.7 mL
