A nurse is caring for four newborns. Which of the following newborns should the nurse assess first?

Correct Answer: A

Rationale: Nasal flaring in a newborn can be a sign of respiratory distress, which is a critical condition that requires immediate attention. It indicates that the newborn is having difficulty breathing and may not be getting enough oxygen. This can be due to various reasons such as lung problems, infections, or other respiratory issues. Therefore, the nurse should assess and address the newborn with nasal flaring first to ensure their breathing is stable and adequate.

Correct Answer: B

Rationale: Phenylketonuria (PKU) is a genetic disorder where the body cannot metabolize phenylalanine, an amino acid found in protein-containing foods. Patients with PKU need to follow a strict low-phenylalanine diet to prevent the buildup of phenylalanine in the body. Fruits like apples and grapes are low in protein and contain minimal phenylalanine, making them suitable choices for individuals with PKU. The other options listed contain higher amounts of protein and phenylalanine, such as peanut butter, chocolate chip cookies, milk, scrambled eggs, and cheese, which should be avoided by individuals with PKU.

Correct Answer: D

Rationale: As women age, their ovarian reserve decreases and the quality of their eggs declines, making it more difficult to conceive. This is due to the normal aging process of the ovaries, which can lead to decreased fertility and an increased risk of chromosomal abnormalities in the embryos. Therefore, a patient who is older than 35 years may have difficulty achieving pregnancy because the ovaries may be affected by the normal aging process.

Correct Answer: C

Rationale: The seminal vesicles are responsible for secreting fluid into the semen during ejaculation. This fluid helps nourish and protect the sperm as they travel through the female reproductive system. The prostate gland, on the other hand, is responsible for producing components of semen that help with sperm motility and viability. The seminal vesicles play a crucial role in the male reproductive system by contributing to the overall composition of semen.

Correct Answer: C

Rationale: The newborn infant whose umbilical cord fell off on day 8 of life is at highest risk of a skin infection. This is because the umbilical cord stump is an area prone to bacterial colonization and can lead to infection if proper care is not maintained during the cord care period. Once the umbilical cord falls off, the skin in that area is exposed and vulnerable to infection. It is important to educate parents on proper cord care techniques to prevent infection in this high-risk period.
