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.

A single crease in the palm.

B.

A notch in the lip.

C.

An inversion of the foot.

D.

Extra digits on the hand.

Answer and Explanation

The Correct Answer is A

Choice A rationale

 

A single crease in the palm, known as a simian crease, is a common characteristic seen in infants with trisomy 21 (Down syndrome) due to the unique hand structure associated with this condition.

 

Choice B rationale

 

A notch in the lip, such as a cleft lip, is not commonly associated with trisomy 21 and is more typically related to other genetic conditions or environmental factors during development.

 

Choice C rationale

 

An inversion of the foot, such as clubfoot, is not a specific characteristic of trisomy 21. This condition is more often seen in other congenital anomalies not related to Down syndrome.

 

Choice D rationale

 

Extra digits on the hand, or polydactyly, is not commonly associated with trisomy 21 but can be seen in other genetic disorders. Trisomy 21 has more specific physical features like the simian crease.

Correct Answer is D

Explanation

Choice A rationale

An apical pulse of 66/min is within the normal range and not indicative of postpartum hemorrhage, which would typically cause an elevated heart rate due to blood loss.

Choice B rationale

A temperature of 38.3°C (101°F) could indicate infection or inflammation but is not a direct sign of postpartum hemorrhage, which primarily involves significant blood loss.

Choice C rationale

Blood pressure of 156/80 mm Hg is elevated but not directly indicative of postpartum hemorrhage, which would typically result in a drop in blood pressure due to loss of blood volume.

Choice D rationale

A respiratory rate of 32/min is significantly elevated and can be a compensatory response to hypovolemia from postpartum hemorrhage. This response occurs as the body tries to increase oxygen delivery due to blood loss.

Correct Answer is B

Explanation

Choice A rationale

Carrots, while nutritious and rich in vitamins, are not a significant source of iron. They provide fiber and beta-carotene but do not meet the increased iron needs during pregnancy.

Choice B rationale

Chicken breast is an excellent source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Consuming chicken breast helps in meeting the increased iron requirements during pregnancy.

Choice C rationale

Apples are healthy and provide essential nutrients and fiber but are not a significant source of iron. They contribute to overall well-being but do not address the specific need for increased iron intake.

Choice D rationale

Feta cheese is a good source of calcium and protein but not iron. While it contributes to nutritional intake during pregnancy, it does not help in meeting the increased iron needs.
