Correct Answer is C
Explanation
Choice A rationale
Measuring and discarding residual gastric contents before feeding is generally avoided in infants because it can disrupt gastrointestinal function and increase the risk of aspiration. Instead, monitoring for signs of intolerance or high residuals through clinical observation is preferred.
Choice B rationale
Using the syringe plunger to push formula at a rate of 5 mL per minute is inappropriate because it can create excessive pressure, leading to discomfort, aspiration, or injury to the gastrointestinal tract. Gravity feeding or using an appropriate pump at a controlled rate is safer.
Choice C rationale
Holding the infant with head and shoulders slightly elevated during feeding is recommended. This position helps to prevent aspiration by ensuring that the formula flows smoothly through the esophagus and into the stomach, reducing the risk of regurgitation.
Choice D rationale
Microwaving refrigerated formula to room temperature is unsafe because microwaving can create hot spots in the formula, posing a burn risk to the infant. It is safer to warm the formula by placing the bottle in warm water and ensuring an even temperature.
Correct Answer is A
Explanation
Choice A rationale
Withholding the dose is the safest action to avoid potential overdose or toxicity. Digoxin has a narrow therapeutic window, and administering an additional dose without knowing how much was absorbed could lead to dangerous side effects.
Choice B rationale
Administering a half dose now is not recommended because it is unclear how much of the original dose was absorbed. This could result in either an insufficient dose or an overdose, leading to ineffective treatment or potential toxicity.
Choice C rationale
Giving another dose is not safe because there is a risk of overdosing the infant. Digoxin toxicity can cause serious complications, and it is crucial to avoid administering more medication until the next scheduled dose.
Choice D rationale
Mixing the next dose with food is not appropriate because it does not address the immediate concern of potential overdose. The priority is to withhold the dose and monitor the infant's condition.
