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 ["B","C","D"]
Explanation
A. Apply warm, moist compresses to the neck area:
Warm, moist compresses are not typically used in the postoperative care of a tonsillectomy. Cold compresses or ice packs may be recommended to reduce swelling.
B. Observe for excessive swallowing:
Excessive swallowing may indicate bleeding, and close monitoring for any signs of bleeding is important.
C. Provide liquid acetaminophen with codeine as ordered:
Pain management is crucial postoperatively, and providing pain medication as ordered helps ensure the child's comfort.
D. Place the child in a partially prone position with the head turned to one side in the immediate post-operative period:
This position helps facilitate drainage and reduce the risk of aspiration. However, the specific positioning may vary based on the surgeon's preference.
E. Offer orange juice, lemonade, or milk to drink once awake and alert:
Citrus juices and milk are usually avoided in the immediate postoperative period to prevent irritation to the surgical site. Clear fluids or those recommended by the healthcare provider are typically introduced gradually.
Correct Answer is C
Explanation
A. Temperament:
Temperament refers to a child's innate traits and behavioral style. While temperament influences how a child responds to social situations, during the school-aged years, the focus often shifts towards developing social skills through interactions with peers.
B. School:
School is a crucial aspect of a child's life, providing opportunities for social interaction, learning, and development. However, within the context of social interaction, the emphasis on school might encompass friendships, group activities, and the overall social environment that the child experiences within the school setting.
C. Peer relationships:
During the school-aged years, peer relationships become particularly important for social development. Children start to form friendships, learn to navigate social situations, and develop a sense of belonging. Peer interactions contribute significantly to emotional and social growth during this stage.
D. Family:
Family plays a fundamental role in a child's development, including social development. However, during the school-aged years, children often begin to explore relationships outside the family circle, and peer relationships become increasingly influential.
