Order: Ceftriaxone 300 mg IV Q12H for a 6 month old infant with a serious infection who weighs 18 lbs. The recommended dosage is 50-75 mg/kg/day in divided doses BID. Prove mathematically (mg/kg/day) the ordered dose and is it safe to give Safe/Unsafe)?
The Correct Answer is ["612.375"]
To calculate the ordered dose of Ceftriaxone in mg/kg/day, we can follow these steps:
Convert the weight to kg:
Weight in kg= Weight in lbs /2.2046
Weight in kg= 18lbs/2.2046≈8.165 kg
Calculate the daily dosage range:
Using the recommended dosage range of 50-75 mg/kg/day:
Minimum daily dosage= 50mg/kg/day × Weight in kg
Maximum daily dosage =75mg/kg/day×Weight in kg
Calculate the ordered dose:
Ordered dose=Dosage per administration × Frequency per day
Ordered dose= 300mg×2times per day= 600mg/day
Now, let's calculate the daily dosage range:
Minimum daily dosage=50mg/kg/day×8.165kg=408.25mg/day
Maximum daily dosage=75mg/kg/day×8.165kg=612.375mg/day
The ordered dose of 600 mg/day falls within the calculated range of 408.25-612.375 mg/day, so the ordered dose is within the recommended dosage range for a serious infection.
Therefore, the ordered dose of Ceftriaxone 300 mg IV Q12H for a 6-month-old infant weighing 18 lbs is considered safe based on the calculated dosage range.

Correct Answer is ["-195"]
Explanation
The water intake is half of 900 mL, which is 450 mL. The soft drink intake is 12 oz, which is equivalent to 355 mL. Therefore, the total fluid intake is 450 + 355 = 805 mL.
The urine output is the sum of the two voids, which is 600 + 350 = 950 mL. The drainage output is 50 mL. Therefore, the total fluid output is 950 + 50 = 1000 mL.
The net I/O is the difference between the fluid intake and output, which is 805 - 1000 = -195 mL. This means that the patient had a negative fluid balance of 195 mL during the night.
Correct Answer is D
Explanation
A. “My child has a vocabulary of approximately 20 words.”
This statement indicates language development, and an 18-month-old with a vocabulary of approximately 20 words is within the expected range. It's a positive indicator of language acquisition.
B. “My child is still thumb sucking.”
Thumb sucking is a common self-soothing behavior in infants and toddlers. While it's a normal behavior, it typically decreases with age. Thumb sucking alone may not necessarily be a cause for concern unless it persists significantly and interferes with other aspects of development.
C. “My child seems to be quite wary of strangers.”
Stranger anxiety is a normal developmental stage, and many children exhibit wariness or fear of unfamiliar people around the age of 18 months. It is considered a typical response and not necessarily indicative of developmental delay.
D. “My child is able to stand but is not yet taking steps independently.”
At 18 months, most children are expected to be walking independently. The inability to take independent steps might be a concern for gross motor skill development. While some variation is normal, a delay in achieving this milestone might prompt further evaluation to rule out any underlying developmental issues.
