Neonatal Nurse Practitioner Flashcards

Which of the following terms describes the use of drugs to try to stop labor?

Answer: Tocolysis

Tocolysis is the medical term for the use of medications, known as tocolytics, to suppress uterine contractions and inhibit preterm labor. These drugs are administered to delay birth, allowing time for fetal lung maturation or transfer to a facility with a higher level of neonatal care. This intervention aims to improve neonatal outcomes by prolonging gestation.

Which of the following conditions in newborns can be brought on by deposits of unconjugated bilirubin?

Answer: Jaundice

Unconjugated bilirubin is a yellow pigment produced from the breakdown of red blood cells. When it accumulates in the blood and deposits in the skin and mucous membranes, it causes jaundice, characterized by a yellowish discoloration. High levels of unconjugated bilirubin can be toxic to the brain (kernicterus) if not managed.

Which of the following is the least accurate statement on the sensory capacities of a full-term newborn?

Answer: At term, the healthy newborn does not yet have an ability to fix on and track objects visually

This statement is inaccurate because full-term newborns are indeed capable of fixing their gaze on objects, especially faces, and can track moving objects. While their vision is not fully developed, they possess these basic visual tracking abilities from birth. They typically prefer high-contrast patterns and can focus on objects within an optimal range of about 8-12 inches.

When a newborn is born with developing lung tissue that is not attached to the airways, this condition is known as:

Answer: Bronchopulmonary sequestration

Bronchopulmonary sequestration is a rare congenital malformation where a portion of lung tissue develops abnormally and is not connected to the normal bronchial tree or pulmonary circulation. Instead, it receives its blood supply from a systemic artery. This unattached, non-functional lung tissue can be intralobar (within the normal lung) or extralobar (separate from the normal lung).

Which of the following is the greatest technique to swiftly remove air from the chest cavity in the case of a baby with pneumothorax symptoms?

Answer: Using a needle and syringe

Needle aspiration using a needle and syringe is the most immediate and life-saving technique for decompressing a tension pneumothorax in a neonate. This procedure rapidly removes trapped air from the chest cavity, alleviating pressure on the heart and lungs. It serves as a crucial bridge to stabilize the infant before a more definitive chest tube insertion can be performed.
