After teaching a pregnant woman about the hormones produced by the placenta, the nurse determines that the teaching was successful when the woman identifies which hormone produced as being the basis for pregnancy tests?

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:

While positioning is important for comfort during labor, addressing the immediate urge to push takes priority. Panting during contractions is the appropriate action.

Choice B reason:

Although observing for crowning is important when the client is close to delivery, the nurse should first intervene to address the client's urge to push since the client is only 7 cm dilated.

Choice C reason:

When a laboring client feels the urge to push but is not yet fully dilated (10 cm), encouraging her to pant can help reduce the urge to push and avoid complications, such as cervical swelling or tearing. This breathing technique helps the client delay pushing until full dilation and readiness of the cervix.
Choice D reason:

Assisting the client to the bathroom would not be appropriate at this stage of labor because the urge to push could lead to unsafe delivery outside the appropriate setting, and movement could increase discomfort or risks.
