The Health Care Provider prescribes Amoxicillin at a dosage of 35mg/kg/dose for a child who weighs 34 lbs. and has Otitis Media. The medication is available in a suspension of 50 mg/ml. What is the total daily dosage in ml for this child?
10 ml
20 ml
30 ml
40 ml .
The Correct Answer is A
Step 1 is to convert the child’s weight from pounds to kilograms.
This is done by dividing the weight in pounds by 2.2, so 34 lbs ÷ 2.2 = 15.45 kg. Step 2 is to calculate the dose in mg. This is done by multiplying the weight in kg by the dosage per kg, so 15.45 kg × 35 mg/kg = 540.75 mg. Step 3 is to convert the dose in mg to ml. This is done by dividing the dose in mg by the concentration of the medication in mg/ml, so 540.75 mg ÷ 50 mg/ml = 10.815 ml. So, the total daily dosage in ml for this child is approximately 10.82 ml, rounded to the nearest hundredth as required.

Correct Answer is B
Explanation
Choice A rationale
A 2+ right pedal pulse indicates a normal pulse and is not a cause for immediate concern in a child with a femur fracture.
Choice B rationale
Tingling in the right foot could indicate nerve damage or compromised blood flow, which can be a serious complication of a femur fracture. This should be the nurse’s priority as it could lead to long-term damage if not addressed promptly.
Choice C rationale
A capillary refill time of less than 2 seconds is considered normal and is not a cause for immediate concern in a child with a femur fracture.
Choice D rationale
A respiratory rate of 24/min is within the normal range for a school-age child and is not a cause for immediate concern in a child with a femur fracture.
Correct Answer is B
Explanation
The correct answer is choice B: Instruct the parent to avoid pressing on the abdominal area.
Rationale for each choice:
- Choice A: Schedule the child for an abdominal ultrasound. While an ultrasound may be necessary for further diagnosis, it is not the immediate priority. The child’s symptoms suggest a possible Wilms’ tumor, a type of kidney cancer that primarily affects children. An ultrasound can help confirm this diagnosis, but it should not be the first action.
- Choice B: Instruct the parent to avoid pressing on the abdominal area. This is the correct answer. If the child has a Wilms’ tumor, pressing on the abdominal area could potentially cause the cancer to spread. Therefore, it is crucial to avoid any unnecessary pressure on the abdomen until further medical evaluation can be performed.
- Choice C: Determine if the child is having pain. While assessing for pain is an important part of nursing care, it is not the immediate priority in this situation. The child’s symptoms need urgent medical attention, and assessing for pain will not provide the necessary information to guide immediate care.
- Choice D: Obtain a urine specimen for a urinalysis. Although a urinalysis can provide valuable information about a patient’s health, it is not the immediate priority in this situation. The child’s symptoms suggest a possible Wilms’ tumor, which requires immediate medical attention. A urinalysis may be part of the diagnostic process, but it should not be the first action taken.
