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.
Rust-stained urine.
B.
Single palmar creases.
C.
Subconjunctival hemorrhage.
D.
Transient circumoral cyanosis
The Correct answer and Explanation is:
The correct answer is B. Single palmar creases.
Explanation:
When a nurse assesses a full-term newborn, certain findings may indicate normal physiological variations, while others could be potential signs of underlying health conditions. Among the options provided, the finding of a single palmar crease is particularly significant and warrants reporting to the healthcare provider.
- Single Palmar Crease (B): A single palmar crease (also known as a “simian crease”) is a single line that runs across the palm of the hand. In most people, there are two palmar creases. A single palmar crease can be a normal variant in some individuals, but it is also associated with several congenital conditions, such as Down syndrome and other chromosomal abnormalities. The presence of a single palmar crease, especially if noted on both hands, could indicate a genetic disorder. Therefore, this finding should be reported for further evaluation, as it may prompt the need for genetic testing or additional assessments to rule out any underlying conditions.
- Rust-Stained Urine (A): Rust-stained urine in a newborn is typically due to urate crystals, which can cause a reddish-orange discoloration of the urine. This is generally a normal finding in the first few days of life, especially if the newborn is slightly dehydrated or not taking in enough fluids. It is not usually a cause for concern and does not need to be reported unless it persists or is associated with other symptoms of dehydration.
- Subconjunctival Hemorrhage (C): Subconjunctival hemorrhage is a common finding in newborns, often resulting from the pressure changes during birth. It appears as a bright red patch in the white of the eye and typically resolves on its own without treatment. It does not indicate a serious problem and does not need to be reported unless it is accompanied by other signs of trauma or illness.
- Transient Circumoral Cyanosis (D): Transient circumoral cyanosis refers to a temporary bluish discoloration around the mouth. This can occur due to minor circulatory adjustments after birth and is often seen when the newborn is crying or cold. It is usually harmless and resolves as the baby’s circulation stabilizes. It does not generally require reporting unless it persists or is accompanied by central cyanosis or respiratory distress.
In summary, the presence of a single palmar crease is the most concerning finding in this list, as it may be indicative of an underlying genetic condition. Therefore, it should be reported to the healthcare provider for further evaluation.
