A client in latent phase of labor for the past 12 hours is requesting medication to help her rest.

Choice A. Accelerations are normal responses that indicate the fetus is healthy and active. Accelerations occur when the fetal heart rate increases in response to stimuli. •

Choice B. Late decelerations are nonreassuring patterns that indicate fetal hypoxia due to placental insufficiency. Late decelerations occur when the placental blood flow decreases due to uterine contractions during labor, causing the fetal heart rate to decrease. •

Choice C. Variable decelerations are nonreassuring patterns that indicate fetal hypoxia due to umbilical cord compression. Variable decelerations occur when the umbilical cord is trapped by the cervical opening or the fetal body part, twisted, or knotted, causing the fetal oxygen supply to be impaired and the fetal heart rate to drop sharply. •

Choice D. Early decelerations are reassuring patterns that indicate a neural reflex due to fetal head compression. Early decelerations occur when the fetal head is compressed by uterine contractions during labor, causing the parasympathetic nervous system to be stimulated and the heart rate to decrease. The correct answer is C. Variable decelerations are the most common pattern that indicates a problem with the umbilical cord and requires urgent intervention.

Choice A reason:

Obtaining blood glucose by heel stick is the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. These signs are suggestive of hypoglycemia, which is a common and potentially serious condition in newborns. Hypoglycemia can result from various causes, such as maternal diabetes, prematurity, intrauterine growth restriction, or perinatal stress. A heel stick is a simple and quick method to obtain blood samples from newborns for glucose testing.

Choice B reason:

Initiating phototherapy is not the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. Phototherapy is used to treat hyperbilirubinemia, which is a condition characterized by high levels of bilirubin in the blood. Hyperbilirubinemia can cause jaundice, which is a yellowish discoloration of the skin and eyes. Jaundice does not typically cause diaphoresis, jitteriness, or lethargy in newborns.

Choice C reason:

Monitoring the newborn's blood pressure is not the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. Blood pressure measurement is not routinely performed in healthy newborns. Blood pressure may be indicated in newborns who have signs of cardiovascular compromise, such as cyanosis, tachycardia, or poor perfusion. Diaphoresis, jitteriness, and lethargy are not specific signs of cardiovascular compromise in newborns.

Choice D reason:

Placing the newborn in a radiant warmer is not the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. A radiant warmer is a device that provides heat to maintain the newborn's body temperature. A radiant warmer may be used for newborns who are at risk of hypothermia, such as those who are premature, have low birth weight, or have cold stress. Diaphoresis, jitteriness, and lethargy are not specific signs of hypothermia in newborns.
