A nurse is educating the parents of a newborn about the Plastibell circumcision technique. Which piece of information should the nurse include in the teaching?

Choice A rationale
Preterm newborns do not have a thick layer of brown fat. Brown fat is a type of fat that generates heat and is typically found in full-term newborns. It helps them maintain their body temperature. Preterm newborns have less brown fat, which makes them more susceptible to hypothermia.
Choice B rationale
Shivering is a mechanism used by the body to generate heat when it’s cold. However, preterm newborns cannot shiver. Their nervous systems are not fully developed, and they lack the muscle coordination necessary to shiver.
Choice C rationale
Sweating is another mechanism the body uses to regulate temperature. When the body is too warm, it produces sweat to cool down. However, preterm newborns do not sweat to cool off when they get too warm. Their sweat glands are not fully developed, and they may not be able to sweat effectively.
Choice D rationale
Preterm newborns have less muscle tone, which exposes more body surfaces to heat loss. Muscle tone provides insulation and generates heat. Because preterm newborns have less muscle mass, they have less insulation and generate less heat, making them more susceptible to hypothermia.

Choice A rationale
Peripheral edema 2+ in bilateral lower extremities is a common finding in the postpartum period and does not necessarily indicate a problem. It can result from the normal fluid shifts that occur after delivery.
Choice B rationale
A blood pressure reading of 136/86 mm Hg is slightly elevated and could indicate the development of postpartum hypertension, a condition that can lead to serious complications such as stroke. This finding necessitates immediate follow-up.
Choice C rationale
Lateral deviation of the uterus could indicate a full bladder, which can interfere with uterine contractions and lead to increased bleeding. This finding necessitates immediate follow-up.
Choice D rationale
Deep tendon reflexes 1+ are within normal limits and do not necessitate immediate follow-up.
Choice E rationale
A large amount of lochia rubra could indicate postpartum hemorrhage, a potentially life- threatening condition. This finding necessitates immediate follow-up.
