A nurse is assessing a child who has a congenital heart defect. The nurse should recognize that which of the following defects is associated with increased pulmonary blood flow?

A. Visual acuity 20/30 bilaterally: Visual acuity of 20/30 bilaterally indicates relatively good vision in both eyes, but it does not necessarily indicate strabismus. Strabismus is related to eye alignment rather than visual acuity.

B. Peripheral vision 70° downward: Peripheral vision refers to the ability to see objects outside the direct line of vision. While changes in peripheral vision can occur in various eye conditions, such as glaucoma, it is not specific to strabismus.

C. Movement of the uncovered eye during a cover test: This is the correct option. During a cover test, one eye is covered while the other eye fixates on an object. If the uncovered eye moves to try to align with the covered eye, it may indicate strabismus or a misalignment of the eyes.

D. Light reflects symmetrically within each pupil during a corneal light reflex test: A corneal light reflex test assesses the alignment of the eyes by observing the reflection of light on the corneas. While asymmetry in the corneal light reflex can indicate strabismus, the description provided in this option suggests that the light reflects symmetrically within each pupil, which is a normal finding.

A. Increased respiratory rate: An increased respiratory rate may indicate that the child is experiencing respiratory distress or discomfort, which could be a sign that suctioning was not effective or that it was too aggressive. Ideally, after suctioning, the child's respiratory rate should stabilize or decrease as they are able to breathe more comfortably with a clear airway.

B. Decreased oxygen saturation: A decreased oxygen saturation level may indicate that the child is not receiving enough oxygen, which could be a sign of ineffective suctioning or airway obstruction. Effective suctioning should improve oxygenation by removing secretions and allowing for better airflow. A decrease in oxygen saturation would suggest the need for further assessment and intervention.

C. Clear breath sounds: This is the correct option. Clear breath sounds indicate that the airway has been effectively cleared of excess secretions, allowing for clear airflow. After suctioning, the nurse should listen for clear breath sounds without any crackles, wheezes, or other abnormal sounds indicating obstruction or congestion.

D. Increased oral secretions: Increased oral secretions may suggest that suctioning was not effective in clearing secretions from the airway, leading to pooling of secretions in the mouth. Effective suctioning should remove excess secretions from the airway, reducing the need for excessive oral secretions.
