A parent brings a 2-week-old infant to a clinic for a phenylketonuria rescreening blood test. The test indicates a serum phenylalanine level of 1 mg/dL (60.5 mcmol/L). The nurse reviews this result and makes which interpretation?
It is inconclusive
it is negative
it requires rescreening at age 6 weeks.
It is positive
The Correct Answer is B
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.

Correct Answer is C
Explanation
A. "I'll check my child's temperature."
Explanation: Monitoring the child's temperature is a general indicator of well-being and can help identify signs of infection or other postoperative concerns.
B. "I'll give medication so that my child will be comfortable."
Explanation: Administering prescribed medication for comfort is a suitable practice to manage postoperative pain or discomfort.
C. "I'll check my child's voiding to be sure there's no problem."
Explanation:
After an orchiopexy procedure, checking voiding may not be directly related to the surgical intervention. Orchiopexy is a procedure to correct cryptorchidism, which involves repositioning an undescended testicle into the scrotum. While monitoring for general signs of well-being is important, specifically checking voiding might not be directly relevant to the surgical recovery process.
D. "I'll let my child decide when to return to play activities."
Explanation: Allowing the child to gradually resume play activities based on their comfort and recovery is a reasonable approach, considering individual variations in recovery times.
Correct Answer is ["C","D","E"]
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.
