A nurse is preparing to administer morphine 0.3 mg/kg PO to a client who weighs 99 lb.

Available is morphine oral solution 4 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.)

Answer and Explanation

The Correct Answer is ["3.4 "]

Given:

Desired dose of morphine: 0.3 mg/kg
Client's weight: 99 lb
Available strength of morphine oral solution: 4 mg/mL

First convert the client's weight from pounds to kilograms: 99 lb ÷ 2.20462 = 44.91 kg (rounded to the nearest hundredth)

The desired dose of morphine:

Desired dose = Client's weight × Dose per kg Desired dose = 44.91 kg × 0.3 mg/kg

Desired dose ≈ 13.473 mg

The milliliters of morphine oral solution this corresponds to:

Volume (mL) = Desired dose / Concentration Volume (mL) = 13.473 mg / 4 mg/mL Volume (mL) ≈ 3.37 mL

So, the nurse should administer approximately 3.4 mL of morphine oral solution.

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 ["5000000"]

Explanation
