What should the parents of infants with a positive phenylketonuria (PKU) test be instructed to do?
Give the infant a high protein diet.
Provide the infant with a diet containing small amounts of phenylalanine.
Early introduction of cow’s milk may be necessary before 1 year of age.
Follow up with a pediatric cardiologist.
The Correct Answer is B
Choice A rationale
Giving an infant with a positive PKU test a high protein diet is not recommended. This is because phenylalanine, which cannot be broken down by individuals with PKU, is found in high-protein foods.
Choice B rationale
Parents of infants with a positive PKU test should provide the infant with a diet containing small amounts of phenylalanine. This is because while phenylalanine is harmful in large amounts to individuals with PKU, it is still an essential amino acid that the body needs in small amounts.
Choice C rationale
Early introduction of cow’s milk is not necessary before 1 year of age for infants with a positive PKU test. In fact, cow’s milk is high in phenylalanine and should be avoided.
Choice D rationale
Following up with a pediatric cardiologist is not specifically related to the dietary management of PKU. While regular medical supervision is important for children with PKU, it does not necessarily have to be with a cardiologist.

Correct Answer is C
Explanation
Choice A rationale
As of my knowledge cutoff in 2021, there is no vaccine available that prevents genital herpes simplex infection from returning.
Choice B rationale
Penicillin is not effective against viral infections such as genital herpes. Antiviral medications are used to manage symptoms and reduce recurrences.
Choice C rationale
This is the most appropriate response. While there is no cure for genital herpes, antiviral medications can help to reduce symptoms and the frequency of recurrences.
Choice D rationale
Having a genital herpes infection does not lead to immunity. The virus remains in the body and can cause recurrent outbreaks.
Correct Answer is ["B","D","E"]
Explanation
Choice A rationale
Unlabored irregular respirations are not typically associated with respiratory distress in a neonate. In fact, newborns naturally have irregular breathing patterns, which can range from fast and shallow to slow and deep.
Choice B rationale
Grunting is a common symptom of respiratory distress in neonates. This is an involuntary noise that a baby makes when exhaling. It’s the baby’s attempt to keep air in the lungs to help them stay open and filled with air.
Choice C rationale
While apneic periods (pauses in breathing) can occur in neonates, a 5-second pause is within the normal range. Apnea of concern in neonates, particularly those with respiratory distress, is usually defined as cessation of breathing for 20 seconds or longer, or a shorter pause if it is accompanied by a slow heart rate or low oxygen levels.
Choice D rationale
Nasal flaring, where the nostrils spread open during breathing, is another common sign of respiratory distress in neonates. It’s an indication that the baby is having to work harder to breathe.
Choice E rationale
Use of accessory muscles is a sign of respiratory distress in neonates. This means the baby is using additional muscles (other than the diaphragm and chest muscles) to breathe. This can be seen as indrawing or retractions, where the skin pulls in between the ribs or the neck sinks in with each breath.
