A mother asks, "Why does my infant have blue hands?".
He is just cold.
He may have been born with a heart problem.
The hands are always blue in a newborn.
The circulation in his hands is not fully developed.
The Correct Answer is D
Choice A rationale:
"He is just cold”. is not the correct choice. While newborns can have cold hands and feet due to their immature thermoregulation, it would not explain persistent blue hands.
Choice B rationale:
"He may have been born with a heart problem”. is not the correct choice as it suggests a congenital heart defect. While cyanosis (bluish discoloration) can be associated with some heart problems, the hands alone being blue is less likely to be solely related to a heart issue.
Choice C rationale:
"The hands are always blue in a newborn”. is not the correct choice. While newborns may have bluish extremities (acrocyanosis) during the first few days after birth due to their developing circulatory system, persistent blue hands beyond this period would require further assessment.
Choice D rationale:
The correct choice is that "The circulation in his hands is not fully developed.”. Newborns have a developing circulatory system, and sometimes, their peripheral circulation takes some time to mature, leading to transient blue hands. However, if the blue color persists or worsens, it's essential to evaluate for any underlying issues.

Correct Answer is ["B","C","D","E"]
Explanation
Choice A rationale:
Drying the baby thoroughly is not directly related to assessing the successful transition of the respiratory system. It is essential for warmth and comfort but does not provide specific information about the respiratory system.
Choice B rationale:
Suctioning the mouth and nose with a bulb syringe to clear mucus is important to ensure the airways are clear and the newborn can breathe effectively. This action helps assess the airway patency and successful initiation of breathing.
Choice C rationale:
Observing the chest and abdomen is crucial to assess the respiratory effort and symmetry. Normal chest movements and equal rise and fall of the abdomen indicate a successful transition of the respiratory system.
Choice D rationale:
Counting the number of respirations per minute is essential to determine if the respiratory rate falls within the expected reference range (around 30-60 breaths per minute for a newborn) and if there are any irregularities.
Choice E rationale:
Observing the color of the mucous membranes is important as cyanosis (blue discoloration) may indicate inadequate oxygenation. Pink mucous membranes are a positive sign, indicating a successful transition of the respiratory system.
Correct Answer is A
Explanation
"My baby will be placed under special lights if the test is elevated.”.
Choice A rationale:
This statement indicates a need for further teaching. Phenylketonuria (PKU) is a metabolic disorder that leads to the accumulation of phenylalanine in the body. If the PKU test is elevated, it means that the baby has high levels of phenylalanine, and immediate dietary intervention is required. The parent's statement about special lights suggests a confusion with jaundice treatment, which is not related to PKU.
Choice B rationale:
This statement is accurate. Before the PKU test is done, the baby needs to consume formula or breast milk to ensure accurate test results.
Choice C rationale:
This statement is also accurate. PKU is a genetic disorder that can be managed with a special diet low in phenylalanine. By adhering to the prescribed diet, the harmful effects of PKU can be minimized.
Choice D rationale:
This statement is accurate. It is common for the PKU test to be repeated at the 2-week check- up to confirm the initial results and ensure early detection and management of PKU if present.
