A dehydrated child has intravenous aid therapy ordered. The child weighs 10 kg. Physician ordered Lactated Ringer's solution 40 ml/kg over 4 hours How many miles per hour will this child receive?
300ml/hour
100 mL/hour
50mL/hour
200 ml/hour
The Correct Answer is B
Infusion rate (mL/hour) = Total volume (mL) / Total time (hours)
Given:
Child's weight: 10 kg
Ordered volume: 40 mL/kg
Total time: 4 hours
First, calculate the total volume of Lactated Ringer's solution needed:
Total volume = 40 mL/kg × 10 kg = 400 mL
Then, divide the total volume by the total time to find the infusion rate:
Infusion rate = 400 mL / 4 hours = 100 mL/hour

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 ["C","D"]
Explanation
A. Keep the infant in a side-lying position.
This intervention is not appropriate following cleft palate repair surgery. Placing the infant in a side-lying position may increase the risk of trauma to the surgical site and disrupt the healing process. It's important to follow the surgeon's recommendations regarding positioning, which typically involves keeping the infant in an upright position to minimize strain on the surgical site.
B. Remove elbow restraints while the infant is sleeping.
Elbow restraints are often used postoperatively to prevent the infant from accidentally touching or rubbing the surgical site, which could disrupt wound healing or cause discomfort. Removing the restraints while the infant is sleeping may increase the risk of unintended movement or injury to the surgical site. Therefore, it is not appropriate to remove the restraints while the infant is sleeping.
C. Administer pain medication around the clock for the first 72 hours.
This intervention is appropriate. Pain management is an essential component of postoperative care following cleft palate repair surgery. Administering pain medication around the clock helps to maintain consistent pain relief and prevent spikes in discomfort. Pain management should be tailored to the individual needs of the infant and may include both non-pharmacological measures and analgesic medications.
D. Feed the infant half-strength formula for the first 48 hours.
This intervention is appropriate. Following cleft palate repair surgery, feeding may need to be adjusted to accommodate the infant's comfort and ensure adequate nutrition while minimizing the risk of aspiration. Feeding the infant half-strength formula or other appropriate feeding methods as recommended by the healthcare provider can help prevent stress on the surgical site and reduce the risk of complications such as aspiration pneumonia.
