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 ["1.8"]

Explanation

Given:

Desired dose of gentamicin: 1 mg/kg
Client's weight: 154 lb
Available strength of gentamicin solution: 40 mg/mL

First, convert the client's weight from pounds to kilograms:

154 lb ÷ 2.2= 70kg

Now, calculate the desired dose of gentamicin:

Desired dose = Dosage per kg × Weight Desired dose = 1 mg/kg × 670 kg Desired dose = 70 mg

Now, find out how many milliliters of gentamicin correspond to this dose: Volume (mL) = Desired dose / Concentration

Volume (mL) = 70 mg / 40 mg/mL Volume (mL) ≈ 1.75mL

rounded off to the nearest tenths= 1.8ml

Correct Answer is ["1"]

Explanation

Client's weight: 220 lb

Desired dose of enoxaparin: 1 mg/kg

Available strength of enoxaparin: 30 mg/0.3 mL

First, convert the client's weight from pounds to kilograms:

220 lb ÷ 2.20462 ≈ 99.79 kg

Now, calculate the desired dose of enoxaparin:

Desired dose = Dosage per kg × Weight Desired dose = 1 mg/kg × 99.79 kg ≈ 99.79 mg 30mg = 0.3ml

Therefore, 99.79mg = 99.79 * 0.3/30

=0.9979

Rounded off to the nearest whole number= 1ml
