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. Place the infant in prone position.
This option is incorrect. Placing the infant in the prone position (lying on the stomach) could put pressure on the spinal lesion, potentially causing discomfort or complications. It's important to minimize pressure on the affected area in infants with spina bifida.
B. Cover the infant's lesion with a dry cloth.
This option is incorrect. While keeping the lesion clean and dry is important for preventing infection, simply covering it with a dry cloth may not provide adequate protection. Proper wound care techniques, such as using sterile dressings and cleaning the area with prescribed solutions, are typically necessary to prevent infection and promote healing.
C. Feed the infant through an NG tube.
This option is incorrect. While infants with severe forms of spina bifida may have difficulty feeding due to associated complications, such as difficulty swallowing or weak sucking reflexes, feeding through a nasogastric (NG) tube is not a standard intervention for spina bifida itself. Feeding methods would depend on the specific needs and abilities of the infant, and may involve breastfeeding, bottle-feeding, or other methods under the guidance of healthcare professionals.
D. Diapering over a low defect will keep the infant free from infection.
This option is correct. Diapering over a low defect (the opening in the spine caused by spina bifida) helps to keep the area clean and reduce the risk of infection. By properly covering the defect with a diaper, exposure to urine and feces, which can increase the risk of infection, is minimized. Additionally, regular diaper changes and proper hygiene practices are essential for preventing complications in infants with spina bifida.
Correct Answer is B
Explanation
A. Applying suction for 20 seconds:
Suctioning for 20 seconds is within the recommended duration for endotracheal suctioning in children. It allows adequate time for removing secretions without causing excessive trauma to the airway.
B. Introducing the catheter without suction:
This action is incorrect. When performing endotracheal suctioning, the catheter should be introduced into the endotracheal tube while applying suction. Introducing the catheter without suction may not effectively remove secretions and can lead to ineffective suctioning.
C. Rotating the catheter between the thumb and forefinger while suctioning:
Rotating the catheter between the thumb and forefinger while suctioning helps to prevent the catheter from sticking to the airway walls and facilitates the removal of secretions. This action is appropriate and helps ensure effective suctioning.
D. Allowing the child to rest for 30 to 60 seconds between suctioning passes:
Allowing the child to rest between suctioning passes helps minimize hypoxia and discomfort during the procedure. This action is appropriate and ensures that the child has adequate time to recover before the next suctioning pass.
