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. Administer the medication at mealtime.Ferrous sulfate is best absorbed on an empty stomach because food, especially those rich in calcium or tannins, can interfere with its absorption. Administering it with meals reduces its effectiveness.
B.While bedtime administration is not contraindicated, it is not necessary. The timing of administration should focus on maximizing absorption, typically between meals or on an empty stomach.
C. Ferrous sulfate can stain teeth if taken orally in liquid form. Using a straw minimizes contact with teeth, reducing the risk of discoloration. Parents should also be advised to encourage the child to rinse their mouth after taking the medication.
D. Dilute the medication with 240 mL of milk. Milk contains calcium, which inhibits the absorption of iron. Ferrous sulfate should not be taken with milk or dairy products to ensure optimal absorption.
Correct Answer is B
Explanation
A. "I will elevate the affected area if possible."
This statement is correct. Elevating the affected area can help reduce swelling and minimize bleeding by promoting venous return. Elevating the limb above the level of the heart can aid in controlling bleeding and is a recommended intervention.
B. "I will apply warm compresses over the site."
This statement is incorrect. Applying warm compresses is generally not recommended for controlling bleeding in hemophilia. Heat can increase blood flow to the area, potentially exacerbating bleeding. Cold compresses or ice packs are typically recommended to help constrict blood vessels and reduce bleeding.
C. "I will have my child rest."
This statement is correct. Resting is an essential component of managing bleeding episodes in children with hemophilia. Physical activity and exertion can increase the risk of injury and bleeding, so it's important for children with hemophilia to avoid strenuous activities during bleeding episodes.
D. "I will promptly mobilize the involved area to relieve pain & decrease bleeding."
Immobilizing the affected area can help control bleeding and reduce pain by minimizing movement. This is also an appropriate response.
