A nurse is preparing to administer amoxicillin 80 mg/kg/day divided into two doses daily to a 2-year-old client who weighs 10 kg (22 lb).
Available is amoxicillin suspension 400 mg/5 mL.
How many mL of amoxicillin should the nurse administer per dose? (Round the answer to the nearest whole number.)
Use a leading zero if it applies. Do not use a trailing zero.
A.
2 mL
B.
4 mL
C.
8 mL
D.
16 mL
The correct answer and Explanation is :
To determine the correct amount of amoxicillin that the nurse should administer per dose, we need to break down the calculation step by step.
Step 1: Calculate the total daily dose
The order specifies a dosage of 80 mg/kg/day. The client weighs 10 kg. So, the total daily dosage will be:
[ 80 \, \text{mg/kg/day} \times 10 \, \text{kg} = 800 \, \text{mg/day} ]
Step 2: Calculate the dose per administration
The total daily dose (800 mg) is to be divided into two doses per day. Therefore, the dose per administration is:
[ 800 \, \text{mg/day} \div 2 = 400 \, \text{mg/dose} ]
Step 3: Use the concentration of the suspension to determine the volume
The available amoxicillin suspension is 400 mg/5 mL. This means that each 5 mL of the suspension contains 400 mg of the drug. Since the nurse needs to administer 400 mg per dose, the volume to administer would be:
[ 400 \, \text{mg} \times \frac{5 \, \text{mL}}{400 \, \text{mg}} = 5 \, \text{mL} ]
Thus, the nurse should administer 5 mL of the suspension per dose.
Final Answer:
The nurse should administer 5 mL per dose.
This is not listed as one of the answer choices, which seems to be a discrepancy in the question provided. However, based on the given parameters and the correct steps of calculation, the nurse would administer 5 mL per dose.
