Primary care provider orders cefazolin (Kefrol) 30 mg/kg in two divided doses per day for a child with pneumonia. Child weighs 20 lb. If the available oral suspension is 125 mg/5ml how many mls per dose should the child receive?
The Correct Answer is ["5.4"]
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.

Correct Answer is B
Explanation
A. Drooling:
Drooling can occur post-tonsillectomy due to throat discomfort or swelling. However, it is not specific to hemorrhage. It may result from pain, swelling, or difficulty swallowing.
B. Continuous swallowing:
Continuous swallowing is indeed a clinical manifestation of hemorrhage after a tonsillectomy. The presence of blood in the throat triggers the swallowing reflex, leading to frequent swallowing by the patient. This symptom is characteristic of hemorrhage and requires immediate medical attention.
C. Poor fluid intake:
Poor fluid intake can occur post-tonsillectomy due to pain, discomfort, or nausea. While it can be a concern for overall recovery, it is not specific to hemorrhage.
D. Increased pain:
Increased pain can be associated with hemorrhage, especially if it is sudden, severe, or worsening. However, it is not as specific as continuous swallowing in indicating hemorrhage post-tonsillectomy. Increased pain can also be due to various other reasons such as inflammation, infection, or trauma.
