A dehydrated child has intravenous aid therapy ordered. The child weighs 10 kg. Physician ordered Lactated Ringer's solution 40 ml/kg over 4 hours How many miles per hour will this child receive?
300ml/hour
100 mL/hour
50mL/hour
200 ml/hour
The Correct Answer is B
Infusion rate (mL/hour) = Total volume (mL) / Total time (hours)
Given:
Child's weight: 10 kg
Ordered volume: 40 mL/kg
Total time: 4 hours
First, calculate the total volume of Lactated Ringer's solution needed:
Total volume = 40 mL/kg × 10 kg = 400 mL
Then, divide the total volume by the total time to find the infusion rate:
Infusion rate = 400 mL / 4 hours = 100 mL/hour

Correct Answer is D
Explanation
A. Flaccid paralysis of lower extremities:
Flaccid paralysis refers to a weakness or loss of muscle tone in the affected muscles, leading to decreased or absent movement. This finding is not typically associated with spina bifida occulta. Instead, it is more commonly seen in more severe forms of spina bifida, such as myelomeningocele, where there is significant involvement of the spinal cord and nerves.
B. Hip dislocation:
Hip dislocation can occur in individuals with myelomeningocele due to muscle weakness, abnormal muscle tone, and joint deformities associated with spinal cord defects. However, it is not typically associated with spina bifida occulta, which usually presents with less severe spinal cord involvement.
C. Hydrocephalus:
Hydrocephalus, characterized by the accumulation of cerebrospinal fluid within the brain, is a common complication of myelomeningocele due to disturbances in the flow and absorption of cerebrospinal fluid caused by the spinal defect. It is less commonly associated with spina bifida occulta, which typically involves a less severe spinal cord defect.
D. Dimple in sacral area:
This is the correct choice. A dimple, patch of hair, or birthmark in the lower back or sacral area is a common finding in spina bifida occulta. It occurs due to the incomplete closure of the spinal column during fetal development, leading to a small defect in the vertebrae. This is often a subtle manifestation of spina bifida occulta and may not cause significant symptoms or functional impairment.
Correct Answer is ["5.4"]
Explanation
Convert the child's weight from pounds (lb) to kilograms (kg):
20 lb × (1 kg / 2.20462 lb) ≈ 9.07 kg
Calculate the total daily dose of cefazolin:
Total daily dose = 30 mg/kg/day × 9.07 kg = 272.1 mg/day
Divide the total daily dose into two equal doses:
Each dose = 272.1 mg / 2 ≈ 136.05 mg
Determine the dose per ml using the available oral suspension concentration:
125 mg/5 ml = 25 mg/ml
Calculate the volume of oral suspension needed for each dose:
Volume per dose = Dose per dose / Concentration per ml
≈ 136.05 mg / 25 mg/ml
≈ 5.44 ml
So, the child should receive approximately 5.44 ml per dose of cefazolin oral suspension.
