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.)

Answer and Explanation

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.

Correct Answer is ["1.9"]

Explanation

Desired dose of isoniazid: 187 mg

Available strength of isoniazid injection: 100 mg/mL

First, find out how many milliliters of isoniazid correspond to the desired dose: Volume (mL) = Desired dose / Concentration

Volume (mL) = 187 mg / 100 mg/mL

Volume (mL) = 1.87 mL

Rounded off to the nearest tenth = 1.9 ml

Correct Answer is ["3.4 "]

Explanation

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.
