Exhibit 1. A nurse understands which of the following assessment findings as a priority to indicate that a newborn may be experiencing cold stress and burning brown fat to produce heat? (Select all that apply.).
Respiratory distress.
Hyperglycemia.
Metabolic alkalosis.
Hypoglycemia.
Correct Answer : A,D
Choice A rationale:
Respiratory distress is a priority assessment finding that indicates a newborn may be experiencing cold stress. Cold stress can cause the baby's body to burn brown fat to generate heat, leading to increased oxygen demand and respiratory distress as a compensatory mechanism.
Choice B rationale:
Hyperglycemia is not associated with cold stress. Instead, hypoglycemia (low blood sugar) is a concern in newborns experiencing cold stress as they deplete their glucose stores to maintain body temperature.
Choice C rationale:
Metabolic alkalosis is not a priority assessment finding for cold stress. Metabolic acidosis (not listed in the options) can be associated with cold stress due to increased anaerobic metabolism, but it is not one of the provided choices.
Choice D rationale:
Hypoglycemia is a priority assessment finding associated with cold stress. As the baby's body uses glucose to produce heat from burning brown fat, it can lead to a drop in blood sugar levels, which is a significant concern in newborns.
Choice E rationale:
Metabolic acidosis is not listed among the provided choices, but it can be associated with cold stress due to the increased production of lactic acid from anaerobic metabolism when trying to generate heat.

Correct Answer is ["The medical term for the soft spot on a baby's skull is fontanelle (or fontanel)."]
Explanation
The medical term for the soft spot on a baby's skull is fontanelle (or fontanel). Fontanelles are gaps between the bones of the skull that allow for the baby's brain to grow and accommodate rapid brain development during infancy. There are typically two fontanelles in a newborn's skull: the anterior fontanelle (located at the top/front of the head) and the posterior fontanelle (located at the back of the head). These fontanelles are composed of connective tissue and remain open during the early months of life, gradually closing as the baby's skull bones fuse together over time. Healthcare professionals often assess fontanelles during routine physical exams of infants. The fontanelle's size and tension can provide valuable information about the baby's hydration status, intracranial pressure, and neurological development.
Normally, the fontanelles should feel relatively soft and flat, indicating proper hydration and brain development. If the fontanelles are sunken or overly tense, it may suggest dehydration or increased intracranial pressure, which requires further evaluation and management. The proper examination of fontanelles is an essential part of newborn care, and any abnormalities observed during assessment should be promptly reported to the healthcare provider for appropriate evaluation and intervention.
Correct Answer is D
Explanation
A. Back to sleep: While placing babies on their backs to sleep is essential for reducing the risk of sudden infant death syndrome (SIDS), it does not prevent flat spots. Instead, tummy time while the baby is awake helps balance the time spent on their back.
B. Take the baby for walks: Taking a baby for walks is beneficial for overall development and stimulation but does not directly prevent flat spots on the head.
C. Keep them awake most of the day: This is not a safe or recommended practice. Babies need sufficient sleep for proper growth and development.
D. Tummy time helps prevent flat spots by reducing the amount of time the baby spends lying on their back. It also strengthens neck, shoulder, and arm muscles, encouraging the baby to move their head more freely and develop motor skills.
