A nurse is caring for a client who is pregnant for the fourth time. The client delivered two full- term newborns and had one spontaneous abortion at 10 weeks of gestation. The nurse should document the client's obstetrical history as which of the following?

Choice A rationale:

Placing the newborn under a radiant heat warmer is used to prevent cold stress. Newborns are at risk of losing body heat rapidly, and cold stress can lead to various complications, including respiratory distress, hypoglycemia, and metabolic acidosis. The radiant heat warmer helps maintain the baby's body temperature within the normal range, promoting overall stability and reducing the risk of cold-related issues.

Choice B rationale:

The nurse should not choose choice B, "Respiratory depression,” as the action used to prevent. Placing the newborn under a radiant heat warmer does not specifically target respiratory depression. Respiratory depression in newborns may be related to various factors, such as anesthesia exposure during delivery or certain medications, and it requires appropriate monitoring and management rather than just heat regulation.

Choice C rationale:

The nurse should not choose choice C, "Thermogenesis,” as the action used to prevent. Thermogenesis refers to the generation of heat in the body, which is essential for maintaining body temperature. While the radiant heat warmer indirectly supports thermogenesis by preventing heat loss, the main purpose of using the warmer is to prevent cold stress, as stated in choice A.

Choice D rationale:

The nurse should not choose choice D, "Tachycardia,” as the action used to prevent. Tachycardia refers to an abnormally fast heart rate, and the use of a radiant heat warmer does not specifically target this condition. The purpose of the warmer, as explained earlier, is to maintain the baby's body temperature and prevent cold stress, not to address tachycardia.

Choice A rationale:

The clinical finding of 0 station does not provide information about the fetal head's position in the left occiput posterior position. Station refers to the level of the presenting part in relation to the ischial spines, not the position.

Choice B rationale:

The clinical finding of 0 station does not indicate that the largest fetal diameter has passed through the pelvic outlet. The station only tells us the level of the presenting part and does not provide information about the diameter passing through the pelvic outlet.

Choice C rationale:

The clinical finding of 0 station does not directly involve the palpability of the posterior fontanel. Station is determined based on the level of the presenting part in the birth canal.

Choice D rationale:

This is the correct interpretation of the clinical finding. 0 station means that the presenting part (usually the baby's head) is at the level of the ischial spines, which serves as a reference point during labor. As labor progresses and the baby moves further down the birth canal, the station becomes more negative (e.g., -1, -2) until delivery occurs.
