Final answer:
The student's question pertains to paediatric medication dosage calculation for Benadryl, using the patient's weight to determine the safe volume to administer. The calculated safe dose based on the patient's weight of 6kg is 6mg, and the volume required from the available medication concentration is 2.4ml for every 6-hour administration.
Step-by-step explanation:
The question involves the calculation of a safe medication dosage for a pediatric patient based on their weight. The ordered medication is Benadryl, at a dosage of 6mg every 6 hours. The safe dose given is 1mg/kg/dose with a maximum dose of 50mg. The patient weighs 6kg, and the medication on hand is a concentration of 25mg per 10ml. To determine if the ordered dose is safe and to calculate the necessary volume to administer, we use the patient's weight:
- Safe dose per administration: 6kg (patient weight) × 1mg/kg = 6mg/dose.
- Since the ordered dose is also 6mg, it is within the safe dose range.
- To find the volume required for a 6mg dose using the available medication concentration (25mg/10ml): (6mg × 10ml) / 25mg = 2.4ml.
The necessary volume of Benadryl to administer to the patient is 2.4ml every 6 hours, ensuring the dose is within the safe limits for the patient's weight.
