A nurse is providing teaching to the guardians of a preterm newborn about temperature instability. Which of the following statements should the nurse make?

Preterm newborns might have a thick layer of brown fat that can cause them to quickly become overheated.

Preterm newborns might shiver to warm up when they get too cool.

Preterm newborns might sweat to cool off when they get too warm.

Preterm newborns might have less muscle tone which exposes more body surfaces to heat loss.

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is B

Explanation

Choice A rationale
A heart rate of 89/min is within the normal range for an adult, and would not typically be a cause for concern.
Choice B rationale
Cool, clammy skin can be a sign of shock or other serious conditions such as hypoperfusion or inadequate blood flow, which could be a sign of hemorrhage or other circulatory issues. This is a significant finding that should be reported to the provider immediately. Hypoperfusion can lead to inadequate oxygen supply to the body’s organs and tissues, which can result in organ failure and other serious complications. Therefore, any signs of hypoperfusion, including cool, clammy skin, should be reported to the provider immediately for further evaluation and treatment.
Choice C rationale
A blood pressure of 120/70 mm Hg is within the normal range for an adult, and would not typically be a cause for concern.
Choice D rationale
Moderate lochia serosa is a normal finding in a woman who is 3 days postpartum. Lochia serosa is the term for the pink or brownish discharge that occurs after lochia rubra, the bright red discharge that occurs immediately after childbirth. Lochia serosa typically begins about 3- 4 days after delivery and can continue for up to 10 days postpartum.

A. “There was no indication of GBS in your earlier prenatal testing.”. B. “Your previous deliveries were all negative for GBS.”. C. “You didn’t report any symptoms of GBS during your pregnancy.”. D. “GBS testing is typically done between 35-37 weeks of gestation.”. .

Correct Answer is D

Explanation

Choice A rationale
While it’s true that there may not have been any indication of GBS in earlier prenatal testing, this does not explain why the test was not conducted earlier. GBS can come and go in the body, so a negative test earlier in pregnancy does not guarantee that the woman will still be GBS-negative later in pregnancy.
Choice B rationale
Even if previous deliveries were all negative for GBS, this does not mean that the woman will not have GBS in this pregnancy. GBS can come and go in the body, so each pregnancy is considered separately.
Choice C rationale
GBS is usually asymptomatic in adults, so the woman would not typically report any symptoms of GBS during her pregnancy. This does not explain why the test was not conducted earlier.
Choice D rationale
GBS testing is typically done between 35-37 weeks of gestation. This is because GBS can come and go in the body, so testing during this time frame gives the best prediction of whether or not the woman will have GBS at the time of delivery.
