A nurse is reviewing the diagnostic findings for a preschool-age child who is suspected of having cystic fibrosis. Which of the following findings should the nurse identify as an indication of cystic fibrosis?

Sweat chloride content 85 mEq/L

72-hour stool analysis sample indicating hard, packed stools

Increased blood levels of fat-soluble vitamins

Chest x-ray negative for atelectasis

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is B

Explanation

Choice A reason: While administering vitamins and minerals is important, it does not provide complete nutrition, especially for a client with such extensive burns and absent bowel sounds.

Choice B reason: This is the correct choice because total parenteral nutrition (TPN) provides complete nutrition intravenously, bypassing the gastrointestinal tract, which is necessary when bowel sounds are absent, indicating a non-functioning GI system.

Choice C reason: Enteral feedings require a functioning GI tract. With absent bowel sounds, this indicates a high risk for complications like aspiration or feeding intolerance.

Choice D reason: Encouraging oral intake is not feasible for a client with extensive burns and absent bowel sounds due to the high risk of inadequate intake and aspiration.

A. Emotional problems B. Urinary tract infections C. Urosepsis D. Progressive kidney disease

Correct Answer is A

Explanation

Choice A reason: Enuresis can lead to emotional problems such as embarrassment, frustration, and low self-esteem, especially if not managed with sensitivity and support.

Choice B reason: While urinary tract infections can cause enuresis, they are not typically a complication of enuresis itself.

Choice C reason: Urosepsis is a severe infection that can result from a urinary tract infection but is not a common complication of enuresis.

Choice D reason: Progressive kidney disease is not a complication of enuresis. Enuresis is a symptom that can occur in various conditions, including kidney disease, but it does not cause the disease to progress.
