A pediatrician has prescribed oxygen as needed for an infant with heart failure. Which situation would likely increase the oxygen demand. requiring the nurse to administer oxygen to the infant?
when a parent is holding the infant
During sleep
When changing the infant's diapers
When drawing blood for electrolyte level testing
The Correct Answer is D
A. When a parent is holding the infant
Explanation: Being held by a parent is generally a comforting and calming experience for an infant, and it is unlikely to significantly increase oxygen demand. In fact, the presence of a familiar caregiver may help reduce stress.
B. During sleep
Explanation: During sleep, an infant's oxygen demand may decrease, and oxygen supplementation may not be necessary unless there are specific indications or concerns about oxygen saturation levels.
C. When changing the infant's diapers
Explanation: Changing a diaper is a routine care activity that is not likely to significantly increase oxygen demand. It is not typically associated with stress or increased metabolic activity that would necessitate additional oxygen.
D. When drawing blood for electrolyte level testing
Explanation:
Drawing blood for electrolyte level testing is a potentially stressful procedure that may cause distress and anxiety in the infant. Stress and anxiety can increase the metabolic rate and oxygen demand. In a situation where an infant is already prescribed oxygen as needed for heart failure, additional stressors like blood drawing may necessitate the administration of oxygen to ensure an adequate oxygen supply

D. Oatmeal
Explanation: Oats themselves are gluten-free, but cross-contamination can occur during processing. Some individuals with celiac disease can tolerate pure, uncontaminated oats, but it's essential to ensure that the oats are labeled gluten-free. Regular oats may be cross-contaminated with gluten-containing grains during processing.

B. 12 months: Doubling of birth weight usually occurs earlier, by around 5 to 6 months, rather than 12 months.
