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

Answer and Explanation

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. That lethargy and vomiting are normal with mumps:
Incorrect: Lethargy and vomiting are not typical symptoms of mumps. These symptoms could indicate a separate issue that requires medical attention.
B. To continue to monitor the child:
Incorrect: Given the reported symptoms of lethargy and vomiting, a passive approach of continuing to monitor may delay necessary medical intervention. The child should be assessed promptly.
C. To bring the child to the clinic to be seen by the pediatrician:
Correct Answer: Lethargy and vomiting are not typical symptoms of uncomplicated mumps. These symptoms could be indicative of other issues, and it's important for the pediatrician to evaluate the child to determine the cause and provide appropriate care.
D. That there is nothing to be concerned about as long as there is no fever:
Incorrect: While fever is a common symptom of mumps, the absence of fever does not negate the need for further evaluation when there are concerning symptoms like lethargy and vomiting. The child should be seen by a healthcare provider to determine the cause of these symptoms.

A. when a parent is holding the infant B. During sleep C. When changing the infant's diapers D. When drawing blood for electrolyte level testing

Correct Answer is D

Explanation

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
