Answer 1

1. Weight of child in pound = 41/2 lb

To find the weight in kg, convert pounds to kg.

1 lb = 0.454 kg

41/2 lb = 0. 454 x 41/2 kg = 2.04 kg.

Answer= 2.04 kg

2. Dose ordered = 125 mcg

Dose in hand = 0.25 mg

Convert 0.25 mg to mcg.

1 mg = 1000 mcg

0.25 mg = 0.25 x 1000 mcg = 250 mcg.

Number of tablets to be given = dose ordered/dose in hand

Number of tablets to be given = 125/250 = 1/2 tablet

The nurse should administer 1/2 tablet in each dose.

3. Dose ordered = 250mg

Dose in hand = 125 mg

Volume = 5ml

Now calculate the dose through following equation

Dose = dose ordered/dose in hand x volume

Dose = 250/125 x 5 = 10 ml

Answer= 10 ml

4. Dose ordered = 800 mg

Dose in hand = 1 gm or 1000 mg

Volume = 10 ml

To calculate the dose use the following equation

Dose = dose ordered/dose in hand x volume

Dose = 800/1000 x 10 = 8 ml

Answer = 8 ml
