A nurse in the emergency department is assessing a newly-admitted infant. Which of the following findings is an early indication of hypoxemia?

Hypoventilation

Tachypnea

Nonproductive cough

Nasal stuffiness

Answer and Explanation

The Correct Answer is B

Choice A reason: Hypoventilation is a late sign of hypoxemia and is characterized by an abnormally slow breathing rate, reducing oxygen intake and increasing carbon dioxide in the blood.

Choice B reason: Tachypnea, or rapid breathing, is an early sign of hypoxemia as the body attempts to increase oxygen levels by breathing more quickly.

Choice C reason: A nonproductive cough is not directly related to hypoxemia, which is a deficiency in the amount of oxygen reaching the tissues.

Choice D reason: Nasal stuffiness is not a specific indicator of hypoxemia and can be associated with various conditions.

Correct Answer is C

Explanation

Choice A reason: The FACES scale is not typically used for infants as they cannot verbally express or select a face that correlates with their pain level.

Choice B reason: The Oucher scale requires a child to point to a face that shows how much pain they are feeling, which is not suitable for infants who cannot communicate their pain verbally.

Choice C reason: The FLACC scale is appropriate for infants as it assesses pain based on five categories of behavior: Facial expression, Leg movement, Activity, Cry, and Consolability.

Choice D reason: The Non-communicating children's pain checklist is designed for children with cognitive impairments and is not the best choice for assessing pain in infants.

A. Sweat chloride content 85 mEq/L B. 72-hour stool analysis sample indicating hard, packed stools C. Increased blood levels of fat-soluble vitamins D. Chest x-ray negative for atelectasis

Correct Answer is A

Explanation

Choice A reason: A sweat chloride content of 85 mEq/L is indicative of cystic fibrosis, as normal values are below 30 mEq/L, and values above 60 mEq/L are diagnostic for cystic fibrosis.

Choice B reason: Hard, packed stools could be a sign of cystic fibrosis but are not as diagnostic as a sweat chloride test.

Choice C reason: Increased blood levels of fat-soluble vitamins are not typically associated with cystic fibrosis; patients often have deficiencies due to malabsorption.

Choice D reason: A chest x-ray negative for atelectasis does not indicate cystic fibrosis, as atelectasis can be present in many conditions.
