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 B
Explanation
A. Coughing spells may be triggered by dust or smoke:
Incorrect: This is a correct statement. Irritants like dust or smoke can trigger coughing spells in a child recovering from pertussis.
B. We need to maintain droplet precautions and a quiet environment for at least 2 weeks.
Correct Answer: Pertussis is highly contagious during the catarrhal and paroxysmal stages, but once the child has reached the convalescent stage (usually after 2-4 weeks of illness), the risk of spreading the infection decreases significantly. Continuing strict droplet precautions and a quiet environment for two weeks after the convalescent stage is not necessary.
C. "We need to encourage our child to drink fluids":
Incorrect: This is a correct statement. Encouraging fluid intake is important to prevent dehydration, especially during coughing spells.
D. Vomiting may occur when our child has coughing episodes:
Incorrect: This is a correct statement. Vomiting can be a common occurrence during coughing episodes in pertussis due to the forceful nature of the cough. Parents should be aware of this symptom.
Correct Answer is A
Explanation
A. "Has the child had any difficulty swallowing food?"
Explanation:
One potential long-term effect of cleft palate repair is difficulty with swallowing or feeding. Cleft palate repair aims to improve the child's ability to eat and speak, but some children may continue to face challenges with swallowing or have a history of difficulty feeding.
B. "Does the child play with an imaginary friend?"
Explanation: Imaginary play is not specifically related to the long-term effects of cleft palate repair. This question does not provide information about the physical outcomes of the surgical repair.
C. "Does the child respond when called by name?"
Explanation: Responsiveness to being called by name is a general developmental question but does not specifically address the long-term effects of cleft palate repair.
D. "Was the child recently treated for pneumonia?"
Explanation: While respiratory issues can be associated with cleft palate, this question focuses on a recent event rather than the long-term effects. Asking about difficulty swallowing or feeding may provide more information about ongoing concerns related to the cleft palate repair.
