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

Explanation
A. Set the water heater at 65.6° C (150° F):
The recommended temperature for a water heater is around 49°C (120°F) to prevent burns. Setting it at 65.6°C (150°F) can lead to scald injuries.
B. Install accordion style gates: Accordion-style gates are not recommended because they can pose a strangulation risk. The safer option is to use gates with vertical or horizontal slats that are spaced closer together.
C. Fit the mattress so that it is snug against the sides of the crib: A snug-fitting mattress prevents gaps where the baby could get trapped or injured.
D. Tie plastic bags in knots before discarding them:
This prevents accidental suffocation or choking hazards that can occur if an infant gets hold of a plastic bag.
E. Serve food in small, non-circular pieces:Serving food in small, non-circular pieces reduces the risk of choking. Infants should be given age-appropriate foods to minimize the risk of choking, and cutting food into small, easy-to-manage pieces is recommended.
Correct Answer is C
Explanation
A. A highly pruritic profuse macule to papule rash on the trunk
Explanation: This description does not fit the typical characteristics of erythema infectiosum. Fifth disease is not typically associated with a highly pruritic rash.
B. A discrete pinkish red maculopapular rash that is spreading to the trunk
Explanation: While erythema infectiosum does involve a rash that can spread to the trunk, the distinctive "slapped face" appearance is a key characteristic that is not captured in this option.
C. An erythema on the face that has a "slapped face" appearance.
Explanation:
Erythema infectiosum, commonly known as fifth disease or slapped cheek syndrome, is characterized by a distinctive facial rash that gives the appearance of a "slapped face." The rash typically starts on the face and then spreads to the trunk and extremities. It often begins with erythema on the cheeks, giving the child a flushed or slapped appearance, followed by a discrete rose-pink maculopapular rash on the trunk.
D. A discrete rose-pink maculopapular rash on the trunk
Explanation: This description fits the typical characteristics of the rash seen in erythema infectiosum, but the key identifier is the "slapped face" appearance on the face.
