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 D
Explanation
A. A 45-degree head elevation: This position can help facilitate venous drainage and reduce intracranial pressure. Elevating the head of the bed may aid in preventing the accumulation of cerebrospinal fluid (CSF) in the brain, which is important after VP shunt insertion to maintain proper drainage. However, this position alone may not be sufficient.
B. On the nonoperative side: Placing the child on the nonoperative side can help reduce pressure on the side where the shunt was inserted, minimizing discomfort and the risk of disruption or displacement of the shunt. However, this position may not directly affect CSF drainage.
C. Prone: Placing the child prone (lying face down) is generally not recommended after VP shunt insertion. This position may increase pressure on the head and interfere with proper CSF drainage, potentially leading to complications.
D. Supine: Placing the child supine (lying on their back) is typically recommended after VP shunt insertion. This position helps promote proper drainage of CSF through the shunt system without placing undue pressure on the surgical site. It also allows for easy monitoring of the child's condition and surgical site.
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.
