The nurse assesses a newborn at 36 weeks' gestation, and the following behaviors are noted: nasal flaring, labored breathing, and excessive mucus. The nurse is most concerned about:
Select one:

Choice A Reason: Possible Meconium Aspiration Syndrome (MAS). This is an unlikely condition for this newborn, as MAS occurs when fetal stool (meconium) enters into the lungs before or during birth, causing airway obstruction, inflammation, and infection. MAS usually affects term or post-term infants who experience fetal distress or hypoxia in utero.

Choice B Reason: Possible polycythemia. This is an unrelated condition for this newborn, as polycythemia refers to an abnormally high number of red blood cells in the blood, which can increase blood viscosity and impair circulation.

Polycythemia may occur in infants who have delayed cord clamping, intrauterine growth restriction, maternal diabetes, or high altitude exposure.

Choice C Reason: Possible Transient Tachypnea of the Newborn (TTN). This is a less serious condition than RDS, as TTN is a mild respiratory problem that results from delayed clearance of fetal lung fluid after birth. TTN causes rapid breathing, nasal flaring, grunting, and mild cyanosis. It usually resolves within 24 to 48 hours after birth.

Choice D Reason: Possible Respiratory Distress Syndrome (RDS). This is a serious condition that requires immediate intervention and treatment, as RDS can lead to life-threatening complications such as pulmonary hemorrhage, pneumothorax, or bronchopulmonary dysplasia. RDS causes respiratory distress, nasal flaring, retractions, grunting, and central cyanosis. It usually occurs within minutes to hours after birth.

Choice A Reason: Vascular spider veins. This is an incorrect answer that refers to a different skin change that occurs during pregnancy, which affects the blood vessels, not the pigment. Vascular spider veins are small red or purple clusters of blood vessels that appear on the skin, especially on the face, neck, chest, or legs. Vascular spider veins are caused by increased blood volume and hormonal changes, which dilate and rupture the capillaries. Vascular spider veins are harmless and usually disappear after delivery.

Choice B Reason: Linea nigra. This is because linea nigra is a term that refers to a darkened vertical line that appears on the abdomen during pregnancy, which runs from the umbilicus to the pubis. Linea nigra is caused by increased production of melanin, which is a pigment that gives color to the skin and hair. Linea nigra is more common and noticeable in women with darker skin tones, and it usually fades after delivery.

Choice C Reason: Melasma. This is an incorrect answer that refers to a different skin change that occurs during pregnancy, which affects the pigment, but not in a linear patern. Melasma is a term that refers to patches of brown or gray-brown discoloration that appear on the face, especially on the forehead, cheeks, nose, or upper lip. Melasma is also caused by increased production of melanin, but it is influenced by sun exposure and genetic factors. Melasma is also known as chloasma or the mask of pregnancy, and it may persist after delivery.

Choice D Reason: Striae gravidarum. This is an incorrect answer that refers to a different skin change that occurs during pregnancy, which affects the connective tissue, not the pigment. Striae gravidarum are stretch marks that appear on the skin, especially on the abdomen, breasts, hips, or thighs. Striae gravidarum are caused by rapid growth and stretching of the skin, which damage the collagen and elastin fibers. Striae gravidarum are initially red or purple, but they fade to white or silver after delivery.
