Pediatric ATI Practice Exam

A nurse is assessing a child with a respiratory infection. Which sign would indicate potential hypoxia?

1. Slowed heart rate below 60 beats per minute.

2. Increased work of breathing.

3. Pursed lip breathing.

4. Color change to a pale or dusky hue.

The correct answer is: Color change to a pale or dusky hue.

In the context of a respiratory infection and its potential to lead to hypoxia, observing a color change to a pale or dusky hue is a critical indicator. This sign suggests that the body's tissues are not receiving adequate oxygen, which can occur when there is impaired gas exchange in the lungs. Hypoxia results from a deficiency in the amount of oxygen reaching the tissues, and one of the body's responses to such a deficiency is to manifest physical signs, including changes in skin color. A pale or dusky hue, particularly around the lips and fingertips, indicates that oxygen levels in the blood may be low and that the child is potentially experiencing respiratory distress. Recognizing these changes promptly can help to ensure that appropriate interventions are initiated to improve the child's oxygenation. The other options, while they can be relevant to respiratory issues, may not directly indicate hypoxia as clearly. For example, slowed heart rate might occur in various conditions unrelated to hypoxia and may not provide immediate insight into oxygen levels. Increased work of breathing can suggest respiratory distress, but it does not alone confirm hypoxia. Pursed lip breathing, often seen in those with obstructive lung disease, can indicate some level of respiratory distress, but unless accompanied by other signs, it is not a
