A nurse is providing teaching to a client who is at 35 weeks of gestation and has a prescription for an amniocentesis. Which of the following client statements indicates an understanding of the teaching?

Choice A rationale
Taking a multivitamin daily is generally recommended during pregnancy to ensure the mother and baby receive necessary nutrients. It does not indicate a need for referral to a dietitian.
Choice B rationale
A weight gain of 4.5 kg (10 lb) since a positive pregnancy test could be a concern depending on the timeframe. If this weight gain occurred rapidly, it could indicate issues such as fluid retention or inadequate nutrition, which would warrant a referral to a dietitian.
Choice C rationale
Nausea, particularly in the morning, is a common symptom of early pregnancy often referred to as “morning sickness”. It does not typically require dietary intervention unless it is severe (hyperemesis gravidarum), leading to weight loss and dehydration.
Choice D rationale
Eating prunes is a natural method to manage constipation, a common issue during pregnancy due to hormonal changes that slow digestion. This choice does not indicate a need for a dietitian referral.

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.
