Incorrect exposure of the image receptor may have happened.
A therapist is viewing a chest X-ray of a pediatric patient who recently emerged from general anesthesia after upper abdominal surgery. The right hemidiaphragm is elevated, and atelectasis is seen as a long, thick horizontal line within the right lower lobe. Which of the following terms describes this type of atelectasis?

Right middle lobe
Which of the following structures on a chest radiograph projects to the left, causes a prominent bulge of the superior mediastinum, and creates a mild indentation on the trachea?

This structure looks like a sail with a sharp inferior margin and lateral margins with wavy contours. Which of the following structures is the therapist observing?

A mucous plug in the right mainstem bronchus
A therapist is viewing a frontal chest radiograph of a neonate who has just been endotracheally intubated. The tip of the endotracheal tube is located between the inferior clavicular border and the carina. What should the therapist do at this time?
Perform a respiratory assessment in the morning and care for an intubated patient at this time.
While viewing an anteroposterior view of a chest radiograph of a 24-month-old intubated child, a therapist notices that the endotracheal tube has now migrated right above the inferior clavicular border. What could explain this new location of the endotracheal tube?

While viewing a lateral view of a neck radiograph of an 18-month-old child, a therapist notices that the epiglottis is enlarged, the aryepiglottic folds are thickened, and the hypopharynx is overdistended. Which of the following conditions does this child likely have?
A mother has just given birth to a 42-week infant who is small for his gestational age.

Which of the following clinical disorders does this infant likely have?
