A nurse is reinforcing teaching with a client who is postpartum about bathing her newborn. Which of the following statements by the client indicates a need for further teaching?

Choice A rationale:

Providing a heat source for the newborn is not the purpose of surfactant. Surfactant is a substance produced in the lungs to reduce surface tension and prevent alveolar collapse during expiration. It helps with the exchange of gases, but it does not generate heat.

Choice B rationale:

This is the correct answer. Surfactant plays a crucial role in assisting the alveoli to remain open by reducing surface tension. This, in turn, allows for proper gas exchange, especially of oxygen and carbon dioxide.

Choice C rationale:

Assisting the ductus arteriosus to remain open is not the purpose of surfactant. The ductus arteriosus is a fetal blood vessel that connects the pulmonary artery to the aorta, bypassing the lungs. After birth, it should close on its own, and surfactant does not influence this process.

Choice D rationale:

Providing energy to the newborn is not the purpose of surfactant. Energy for the newborn comes from nutrition, particularly breast milk or formula, and not from surfactant

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.
