What clinical manifestation in a newborn would cause a nurse to suspect the diagnosis of tracheoesophageal fistula (TEF)?
An orogastric tube fails to pass at birth.
The infant has a low birth weight.
It is visually identified at the time of delivery.
Dry mouth and nares, little to no oral secretions at delivery.
The Correct Answer is A
Choice A reason: This is the correct choice. If an orogastric tube fails to pass, it may indicate a blockage or abnormal connection, such as a tracheoesophageal fistula.
Choice B reason: Low birth weight can be associated with many conditions and is not specific to TEF.
Choice C reason: TEF is not typically visible without special imaging or procedures; it cannot be visually identified at delivery.
Choice D reason: Dry mouth and nares with little to no oral secretions could indicate other conditions and are not specific to TEF. TEF often presents with excessive oral secretions.

Choice B reason: This is the correct choice. Bone marrow suppression is a common side effect of chemotherapy, leading to a decreased production of blood cells and necessitating precautions to prevent infection.
Choice C reason: T-cell mediated hypersensitivity is not a common side effect of chemotherapy that would dictate the type of precautions needed.
Choice D reason: Stomatitis is a possible side effect of chemotherapy, but it does not primarily determine the type of precautions required as bone marrow suppression does.

Choice C reason: While a 10-year-old could use PCA, the presence of a concussion may impair their ability to use it properly.
