A nurse in the newborn nursery is caring for an infant who has trisomy 21. When collecting data, which of the following findings should the nurse expect?

A single crease in the palm

A notch in the lip

Extra digits on the hand

An inversion of the foot

Answer and Explanation

The Correct Answer is A

A. A single crease in the palm is correct. A single transverse palmar crease (simian line) is a common finding in infants with trisomy 21.
B. A notch in the lip is not a common finding in trisomy 21. This feature is more associated with other conditions like cleft lip or palate.
C. Extra digits on the hand (polydactyly) is not characteristic of trisomy 21. It is more commonly associated with other genetic conditions.
D. An inversion of the foot (clubfoot) is not a specific finding for trisomy 21. While some infants with trisomy 21 might have foot deformities, this is not a defining characteristic.

Correct Answer is C

Explanation

A. A Mongolian spot is a benign, pigmented skin mark common in newborns, particularly those with darker skin. It is not related to rubella exposure during pregnancy.
B. Jaundice in the newborn can be a common finding and is not specifically related to maternal rubella exposure. Jaundice often resolves with time or may require treatment, but it is not a direct consequence of rubella.
C. Deafness is a known congenital defect associated with rubella syndrome. Infants exposed to rubella during pregnancy are at risk for serious outcomes, including hearing impairments.
D. Transient strabismus is a common condition in newborns and is not specifically associated with maternal rubella exposure. It typically resolves as the baby grows.

A. "Place a rolled blanket behind the newborn's neck during extended trips." B. "Position the newborn's car seat at a 45° angle." C. "Position the retainer clip at the level of the newborn's umbilicus." D. "Place the newborn's car seat in a forward-facing position."

Correct Answer is B

Explanation

A. Placing a rolled blanket behind the newborn’s neck is unsafe and can cause improper positioning in the car seat. The newborn should be positioned properly according to the car seat manufacturer's instructions to ensure safety during travel.
B. The car seat should be positioned at a 45° angle to keep the newborn’s airway open and prevent slumping. This angle supports proper head and neck alignment, which is essential for the baby’s safety and comfort during travel.
C. The retainer clip should be positioned at the level of the newborn’s armpits, not the umbilicus. Proper placement of the retainer clip ensures that the harness is secure and correctly positioned over the baby’s shoulders.
D. Newborns should be placed in a rear-facing position in the car seat for optimal safety. Forward-facing car seats are used later, but infants should always be in a rear-facing car seat until they meet the age, weight, and height requirements for transitioning.
