The most appropriate time for the nurse to encourage a laboring woman to push is during

Choice A reason:

Placing a covering on the scale tray when weighing an infant helps to ensure that conductive heat loss from the infant is minimal. Newborns and infants are especially vulnerable to temperature changes, and maintaining their body temperature is crucial for their well-being. By placing a covering, such as a soft cloth or blanket, on the scale tray, the nurse creates a barrier between the infant's skin and the cold surface of the scale. This reduces the risk of heat loss from direct contact with the scale, helping to keep the baby comfortable and preventing any potential adverse effects from exposure to low temperatures during the weighing process.

Choice B reason:

Choice B, compensating for the negative weight balance to ensure the correct weight, is not the primary reason for using a covering on the scale tray. The negative weight balance, if any, would be minimal and not significant enough to affect the accuracy of the infant's weight measurement. The main concern when using a scale for weighing infants is to ensure their comfort and safety during the process.

Choice C reason:

Choice C, avoiding causing multiple startle (Moro) reflexes when weighing, is not the main reason for using a covering on the scale tray. The Moro reflex is a normal startle response in infants and is not typically affected by whether or not a covering is placed on the scale tray.

The nurse can support the infant appropriately during weighing to minimize any startle reflexes, regardless of whether a covering is used.

Choice D reason:

Choice D, avoiding contaminating the nurse's hands with blood or other body substances, is not directly related to using a covering on the scale tray. The primary purpose of using a covering is to minimize heat loss, as explained in Choice A. However, it is standard practice for healthcare professionals to wear gloves when handling blood or body substances to prevent any potential transmission of infections, ensuring both the nurse's and the infant's safety.

Choice A reason:

The woman in early labor with contractions every 5 minutes lasting 40 seconds each does not require the immediate discontinuation of the oxytocin (Pitocin) infusion. Early labor is characterized by mild and infrequent contractions as the cervix begins to dilate and efface. Choice B reason:

The woman in active labor with contractions every 30 minutes lasting 60 seconds each also does not warrant immediate discontinuation of the oxytocin (Pitocin) infusion. Active labor typically involves regular and stronger contractions as the cervix continues to dilate and the baby progresses downward.

Choice C reason:

The woman in active labor with contractions every 2 to 3 minutes lasting 70 to 80 seconds each does not require immediate cessation of the oxytocin (Pitocin) infusion. These contractions are within the expected range for active labor and may be considered normal.

Choice D reason:

The woman in transition with contractions every 1.5 minutes lasting 95 seconds each should have the oxytocin (Pitocin) infusion discontinued immediately. Transition is the most intense phase of labor, characterized by rapid and strong contractions as the cervix completes dilation. Prolonged and frequent contractions during this phase can lead to uterine hyperstimulation, which can compromise fetal oxygenation and result in fetal distress. Discontinuing the oxytocin infusion is necessary to reduce the intensity and frequency of contractions, ensuring better fetal well-being during this critical phase of labor.
