A nurse is assessing a newborn who was born at 42.5 weeks of gestation. Which of the following findings should the nurse expect?

A.

Faint red marks on the plantar surface.

B.

Copious vernix.

C.

Dry, cracked skin.

D.

Scant scalp hair.

Answer and Explanation

The Correct Answer is C

Choice A rationale

 

Faint red marks on the plantar surface are more common in preterm infants and are not typically seen in post-term infants.

 

Choice B rationale

 

Copious vernix is usually seen in preterm infants. Post-term infants often have little to no vernix.

 

Choice C rationale

 

Dry, cracked skin is a common finding in post-term infants due to prolonged exposure to the amniotic fluid.

 

Choice D rationale

 

Scant scalp hair is more common in preterm infants. Post-term infants usually have more developed hair.

Correct Answer is C

Explanation

Choice A rationale

Depressed fontanelles are not exclusive to premature newborns. They can occur in both premature and full-term infants and are not an indicator of prematurity.

Choice B rationale

Depressed fontanelles do not indicate infection. Infections in newborns typically present with other symptoms such as fever, irritability, and poor feeding.

Choice C rationale

Depressed fontanelles are a sign of dehydration in newborns. When a newborn is dehydrated, the fontanelles can appear sunken due to the lack of fluid in the body.

Choice D rationale

Depressed fontanelles are not a normal finding in newborns. Normally, fontanelles should be flat or slightly curved inward. A depressed fontanelle is a clinical sign that requires further evaluation and intervention.

Correct Answer is D

Explanation

Choice A rationale

A respiratory rate of 110/min is too high for a newborn and may indicate respiratory distress.

Choice B rationale

A respiratory rate of 100/min is also too high for a newborn and may indicate respiratory distress.

Choice C rationale

A respiratory rate of 24/min is too low for a newborn and may indicate respiratory depression.

Choice D rationale

The normal respiratory rate for a newborn is between 30 to 60 breaths per minute. A rate of 60/min is within this range.
