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: Obtain a bilirubin level. This is an incorrect answer that indicates an irrelevant and unnecessary nursing action for a newborn with tremors or jiteriness. Obtaining a bilirubin level is a nursing action that is indicated for a newborn with jaundice (yellowish discoloration of the skin and mucous membranes), which can occur due to increased bilirubin production or decreased bilirubin excretion. Jaundice does not cause tremors or jiteriness in newborns.

Choice B Reason: Place a pulse oximeter on the newborn. This is an incorrect answer that suggests an inappropriate and insufficient nursing action for a newborn with tremors or jiteriness. Placing a pulse oximeter on the newborn is a nursing action that measures oxygen saturation and heart rate, which can indicate hypoxia (low oxygen level) or distress in newborns. Hypoxia can cause tremors or jiteriness in newborns, but it is not the only or most likely cause. Placing a pulse oximeter on the newborn does not provide enough information to diagnose or treat hypoglycemia.

Choice C Reason: Obtain a blood glucose level. This is because tremors or jiteriness are common signs of hypoglycemia (low blood glucose) in newborns, which can occur due to various factors such as prematurity, maternal diabetes, infection, or cold stress. Hypoglycemia can cause neurological damage or death if not treated promptly and effectively. Obtaining a blood glucose level is a nursing action that has the highest priority for a newborn with tremors or jiteriness, as it can confirm the diagnosis and guide the treatment.

Choice D Reason: Take the newborn's vital signs. This is an incorrect answer that implies an inadequate and delayed nursing action for a newborn with tremors or jiteriness. Taking the newborn's vital signs is a nursing action that monitors temperature, pulse, respiration, and blood pressure, which can indicate general health status and stability in newborns. Taking the newborn's vital signs may reveal signs of hypoglycemia, such as hypothermia, tachycardia, tachypnea, or hypotension, but it is not a specific or definitive test for hypoglycemia. Taking the newborn's vital signs may also waste valuable time that could be used to obtain a blood glucose level and initiate treatment.

Choice A Reason: Homans' sign. This is an incorrect answer that refers to a different sign that is not related to pregnancy. Homans' sign is a sign of deep vein thrombosis (DVT) that occurs when there is pain or discomfort in the calf or popliteal region when the foot is dorsiflexed. Homans' sign can be elicited by passive or active movement of the foot, but it is not a reliable or specific indicator of DVT.

Choice B Reason: Chadwick's sign. This is an incorrect answer that refers to a different sign of pregnancy that affects the color of the cervix, not the texture. Chadwick's sign is a sign of pregnancy that refers to the bluish or purplish discoloration of the cervix, vagina, and vulva due to increased blood flow and congestion. Chadwick's sign can be observed by visual inspection of the cervix during the first prenatal visit, usually around 6 to 8 weeks of gestation.

Choice C Reason: Goodell's sign. This is because Goodell's sign is a sign of pregnancy that refers to the softening of the cervix due to increased vascularity and edema. Goodell's sign can be detected by digital examination of the cervix during the first prenatal visit, usually around 6 to 8 weeks of gestation.

Choice D Reason: McDonald's sign. This is an incorrect answer that refers to a different sign of pregnancy that involves the angle of the uterus, not the cervix. McDonald's sign is a sign of pregnancy that refers to the ease of flexing the body of the uterus against the cervix, which creates an angle of 90 degrees or less. McDonald's sign can be assessed by bimanual examination of the uterus during the first prenatal visit, usually around 7 to 8 weeks of gestation.
