Final answer:
To calculate the amount of cephalexin 125mg/5mL oral suspension to administer to the client who weighs 77 pounds, first calculate the client's weight in kilograms. Then calculate the recommended safe dose based on the weight. Finally, calculate the amount of cephalexin oral suspension to administer based on the total daily dose and concentration of the suspension.
Step-by-step explanation:
To calculate the amount of cephalexin 125mg/5mL oral suspension to administer to the client, we first need to determine the client's weight in kilograms. The client weighs 77 pounds, which is approximately 35 kilograms.
Next, we calculate the recommended safe dose for the client based on their weight. The recommended safe dose is 25mg/kg/24 hours. Multiplying 25mg by 35kg gives us 875mg as the total daily dose.
Finally, we can calculate the amount of cephalexin oral suspension (125mg/5mL) the nurse should administer. If the total daily dose is 875mg and the concentration of the suspension is 125mg/5mL, then the nurse should administer 35mL of the oral suspension.
