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

Correct Answer is ["260"]
Explanation
To calculate the total fluid intake, add the volumes of each item consumed:
Juice: ½ cup
1 cup = 240 mL
½ cup = 240 mL / 2 = 120 mL
Gelatin: 3 oz
1 oz ≈ 30 mL
3 oz = 3 * 30 mL = 90 mL
Ice pop: 1 oz
1 oz ≈ 30 mL
1 oz = 30 mL
Ginger ale: 20 mL
Now, add these values:
120 mL (juice) + 90 mL (gelatin) + 30 mL (ice pop) + 20 mL (ginger ale) = 260 mL
Therefore, the nurse should record 260 mL as the child's fluid intake.
Correct Answer is B
Explanation
A. It is inconclusive
Explanation: A serum phenylalanine level within the normal range is considered conclusive in ruling out phenylketonuria. Inconclusive results typically occur when there are issues with the sample or testing process.
B. It is negative
Explanation:
A serum phenylalanine level of 1 mg/dL (60.5 mcmol/L) in a 2-week-old infant is within the normal range. In the context of phenylketonuria (PKU) screening, a "negative" result means that the phenylalanine levels are within the expected range, and there is no evidence of phenylketonuria.
C. It requires rescreening at age 6 weeks.
Explanation: If the initial screening result is within the normal range, rescreening at age 6 weeks may not be necessary for phenylketonuria. The timing and need for rescreening may vary based on local protocols and individual patient factors.
D. It is positive
Explanation: A positive result for phenylketonuria would indicate that the serum phenylalanine levels are elevated, suggesting a potential diagnosis of PKU. In this case, the result is negative, meaning there is no evidence of PKU.
