A nurse is assessing a full-term newborn upon admission to the nursery. Which of the following clinical findings should the nurse report to the provider?
A.
Transient circumoral cyanosis
B.
Single palmar creases
C.
Rust-stained urine
D.
Subconjunctival hemorrhage
The Correct answer and Explanation is:
Correct Answer: C. Rust-stained urine
Explanation:
When assessing a full-term newborn, it is important for the nurse to differentiate between normal variations in newborn physiology and findings that may indicate an underlying condition requiring medical intervention.
Rust-stained urine (C) is an abnormal finding in a newborn and should be reported to the provider. Rust-stained urine is often indicative of urate crystals, which can occur due to dehydration. While urate crystals can be common in the first few days of life as the newborn transitions from intrauterine to extrauterine life and as breast milk production increases, they should still be reported to the provider. This is especially important if the newborn is showing other signs of dehydration, such as poor feeding, decreased wet diapers, or lethargy. Dehydration in a newborn can lead to serious complications, including electrolyte imbalances and impaired organ function, making it crucial for early recognition and intervention.
Transient circumoral cyanosis (A) refers to a bluish tint around the mouth, which can occur intermittently in newborns due to their immature circulatory system and vasomotor instability. This type of cyanosis is often transient and not a cause for concern unless it persists or is accompanied by central cyanosis or respiratory distress.
Single palmar creases (B), also known as simian creases, can be a normal finding. While a single palmar crease can be associated with certain genetic conditions like Down syndrome, its presence alone in an otherwise healthy newborn is not an immediate concern and does not require urgent reporting.
Subconjunctival hemorrhage (D) is another common and benign finding in newborns. It occurs due to the rupture of small blood vessels in the eyes during the birthing process, especially in cases of vaginal delivery. Subconjunctival hemorrhages typically resolve on their own without any treatment.
In summary, among the options provided, rust-stained urine is the most concerning and requires reporting to the provider due to its association with dehydration and potential complications if not addressed promptly. The other findings—transient circumoral cyanosis, single palmar creases, and subconjunctival hemorrhage—are generally considered normal or benign in the context of a full-term newborn.
