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 C
Explanation
A. Obtain a throat culture.
This option is not appropriate as a primary nursing action in the acute management of epiglottitis. While obtaining a throat culture may be necessary for diagnostic purposes, it is not a priority in the immediate care of a child with suspected epiglottitis. The focus should be on ensuring airway patency and providing emergency treatment.
B. Visualize the epiglottis using a tongue depressor.
This option is contraindicated in the acute management of epiglottitis. Direct visualization of the epiglottis using a tongue depressor or other instruments can provoke spasm of the epiglottis and worsen airway obstruction. Attempting to visualize the epiglottis should be avoided until the child's airway has been secured in a controlled environment, such as in the operating room under anesthesia.
C. Provide moist air to reduce the inflammation of the epiglottis.
This option is appropriate. Providing moist air, such as humidified oxygen or a cool mist, can help soothe the inflamed tissues of the epiglottis and upper airway. Moist air may help alleviate discomfort and reduce inflammation, although it will not directly address the risk of airway obstruction. It is often used as supportive therapy in conjunction with other interventions.
D. Initiate airborne precautions.
This option is not necessary for the care of a child with epiglottitis. Epiglottitis is not typically transmitted through airborne droplets. The priority in the management of epiglottitis is ensuring a patent airway and providing appropriate treatment to reduce inflammation and prevent complications.
Correct Answer is A
Explanation
A. Lethargy: Lethargy can be a concerning sign in a postoperative child, especially following a procedure involving the central nervous system like VP shunt insertion. It could indicate increased intracranial pressure or other neurological complications, which require immediate attention. Therefore, this is a priority finding.
B. Urine output 70 mL in 2 hr: While monitoring urine output is important for assessing hydration and renal function, a urine output of 70 mL in 2 hours may not be immediately concerning in a 4-year-old child. However, if this pattern continues or if there are signs of dehydration, it should be addressed. It's not as urgent as assessing for neurological changes.
C. Lying flat on the unaffected side: The positioning of the child, lying flat on the unaffected side, may or may not be concerning depending on the specific instructions provided postoperatively. While positioning can affect the function of the VP shunt, it may not necessarily indicate an immediate complication.
D. Respiratory rate 20/min: A respiratory rate of 20 breaths per minute is within the normal range for a 4-year-old child. While changes in respiratory rate can indicate respiratory distress, this respiratory rate alone is not immediately concerning.
