Choice A rationale

While it is true that preterm newborns have a smaller body surface area than full-term newborns, this is not the primary reason for using an incubator. A smaller body surface area can contribute to heat loss, but the main issue is the lack of adequate temperature control mechanisms.

Choice B rationale

Preterm newborns lack the adequate temperature control mechanisms that full-term newborns have. They have less subcutaneous fat to insulate them and a higher surface area to volume ratio, which increases heat loss. They also lack the ability to shiver to generate heat.

Therefore, an incubator is used to maintain a neutral thermal environment.

Choice C rationale

The heat in the incubator does not rapidly dry the sweat of preterm newborns. In fact, preterm newborns do not sweat as efficiently as full-term newborns or adults, so they are less likely to lose heat through sweating.

Choice D rationale

The statement that the added brown fat layer in preterm newborn reduces his ability to generate heat is incorrect. In fact, preterm newborns have less brown fat than full-term newborns. Brown fat is a type of fat that generates heat when metabolized, and it is an important source of heat for newborns.

Choice A rationale

Hemoglobin is an important parameter to monitor in newborns, especially those who have undergone a stressful birth process like an emergency cesarean section due to abruptio placenta and non-reassuring fetal heart rate. However, it is not one of the immediate findings that the nurse should report to the provider in this context.

Choice B rationale

Hematocrit is a measure of the proportion of red blood cells in the blood. While it is an important parameter to monitor in newborns, it is not one of the immediate findings that the nurse should report to the provider in this context.

Choice C rationale

Serum glucose is an important parameter to monitor in newborns, especially those who have undergone a stressful birth process like an emergency cesarean section due to abruptio placenta and non-reassuring fetal heart rate. However, it is not one of the immediate findings that the nurse should report to the provider in this context.

Choice D rationale

A respiratory assessment is crucial for a newborn, especially one that has undergone a stressful birth process like an emergency cesarean section due to abruptio placenta and non- reassuring fetal heart rate. The newborn’s Apgar score was 5 at 1 min, which indicates significant distress, and positive pressure ventilation was given for 1 min followed by free flow oxygen. These factors make respiratory assessment a priority and one of the immediate findings that the nurse should report to the provider.

Choice E rationale

Temperature is an important parameter to monitor in newborns, especially those who have undergone a stressful birth process like an emergency cesarean section due to abruptio placenta and non-reassuring fetal heart rate. However, it is not one of the immediate findings that the nurse should report to the provider in this context.
