A nurse is educating the mother of a newborn who was born small for gestational age. Which of the following should the nurse include as a potential cause of this condition?
Perinatal asphyxia.
Preterm delivery.
Fetal hyperinsulinemia.
Placental insufficiency.
The Correct Answer is D
Choice A rationale
Perinatal asphyxia refers to a lack of oxygen flow to the fetus around the time of birth. This can lead to multiple organ dysfunction and neurological issues, but it is not a common cause of a newborn being small for gestational age.
Choice B rationale
Preterm delivery can result in a newborn being small for their gestational age simply because they have not had the full amount of time to grow in the womb. However, preterm babies are typically compared to other preterm babies when assessing size, not to full-term babies.
Choice C rationale
Fetal hyperinsulinemia, or an excess of insulin in the fetus, can lead to excessive growth and a larger-than-average baby size (macrosomia), not a smaller size.
Choice D rationale
Placental insufficiency, where the placenta does not work as well as it should, can limit the amount of oxygen and nutrients the fetus receives. This can restrict the baby’s growth, leading to a small size for gestational age.

Correct Answer is B
Explanation
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.
Correct Answer is A
Explanation
Choice A rationale
Elevating the leg can help reduce swelling and improve blood flow, which can alleviate pain and redness in the calf. This is a non-pharmacological intervention that the client can easily do at home.
Choice B rationale
Applying cold compresses is typically used for acute injuries to reduce inflammation and numb the area. However, in the case of a postpartum client reporting pain and redness in her calf, this could potentially be a sign of a deep vein thrombosis (DVT), and applying cold compresses may not be the most appropriate intervention.
Choice C rationale
Flexing the knee while resting is not typically recommended for a client with symptoms that may indicate a DVT. This position does not promote venous return and could potentially exacerbate the condition.
Choice D rationale
Massaging the area is not recommended if a DVT is suspected, as it could dislodge a blood clot and cause a pulmonary embolism.
