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: Removing personal objects from the room is not reflective of palliative care principles, which focus on comfort and personal significance.

Choice B reason: Listening and responding to the family's discussions about their child's life aligns with the holistic approach of palliative care, which includes emotional support.

Choice C reason: Expressing personal feelings of missing the client is not indicative of an understanding of palliative care roles and responsibilities.

Choice D reason: Being hopeful about new medications is not relevant to palliative care, which focuses on quality of life rather than curative treatment.

A. Rapid growth spurts B. Thin, watery mucus C. Wheezing D. Barrel-shaped chest

Correct Answer is ["C","D"]

Explanation

Choice A reason: Rapid growth spurts are not associated with cystic fibrosis. Instead, patients often experience poor growth due to malabsorption.

Choice B reason: Thin, watery mucus is not typical in cystic fibrosis. The mucus is usually thick and sticky, leading to blockages in the lungs and pancreas.

Choice C reason: Wheezing is a common symptom in cystic fibrosis due to the obstruction of the airways by thick mucus.

Choice D reason: A barrel-shaped chest can develop in cystic fibrosis due to chronic lung infections and air trapping.

Choice E reason: Clubbing of fingers and toes is a sign of chronic hypoxia, which can occur in cystic fibrosis due to long-standing lung disease.
