(Record the answer to the nearest tenth. Do not include units in the answer.)

Cevap: 0.6 mL

Cevap

0.6
To determine the correct volume to administer, the nurse must first convert the client's weight to kilograms: 198 lb÷2.2=90 kg198\text{ lb} \div 2.2 = 90\text{ kg}. Next, the desired dose is calculated by multiplying the weight by the prescribed amount: 90 kg×1 mg/kg=90 mg90\text{ kg} \times 1\text{ mg/kg} = 90\text{ mg}. Finally, the volume is calculated using the formula (Desired / Have) ×\times Volume: (90 mg÷120 mg)×0.8 mL=0.6 mL(90\text{ mg} \div 120\text{ mg}) \times 0.8\text{ mL} = 0.6\text{ mL}.
