A nurse is teaching the guardian of a child who is suspected of having cystic fibrosis and is scheduled for a sweat chloride test. Which of the following statements should the nurse include?
"Two separate samples will be collected to ensure accuracy of the test results."
"It will take approximately 3 hours to complete the test."
"Your child will need to receive sedation to minimize pain during the test."
"Your child should avoid eating and drinking 6 hours prior to the test."
The Correct Answer is A
A. "Two separate samples will be collected to ensure accuracy of the test results." For accuracy, the sweat chloride test is typically done with two separate samples to confirm the diagnosis of cystic fibrosis. The results are compared to ensure consistency.
B. "It will take approximately 3 hours to complete the test." The sweat chloride test typically takes around 30 to 60 minutes, not 3 hours. The process of stimulating sweat production and collecting it is usually brief.
C. "Your child will need to receive sedation to minimize pain during the test." The sweat chloride test is non-invasive and does not require sedation. It involves the application of a sweat-stimulating chemical, and the child may feel mild discomfort but does not require sedation.
D. "Your child should avoid eating and drinking 6 hours prior to the test." There are no specific fasting requirements before a sweat chloride test, although the child may be asked to stay well-hydrated to help produce sweat during the test.

Correct Answer is C
Explanation
A. Urine output 25 mL/hr – This is an adequate urine output for a school-age child and does not require withholding digoxin.
B. Oxygen saturation 88% – While low, this does not directly indicate digoxin toxicity or require withholding the medication. The underlying cause should be evaluated.
C. Heart rate 64/min – Digoxin can cause bradycardia, and a heart rate of 64/min is too low for a school-age child. Generally, digoxin should be withheld if the heart rate is below 70 bpm in children or below 90 bpm in infants.
D. Respiratory rate 18/min – This is within the normal range for a school-age child and does not warrant withholding digoxin.
Correct Answer is B
Explanation
A. "The blood pressure medicine I'm taking will help to keep my insulin level low." This is incorrect. Blood pressure medications do not regulate insulin levels.
B. "I will increase my food intake before I exercise." Exercise can lower blood glucose levels, increasing the risk of hypoglycemia. Eating a snack before exercise helps prevent this.
C. "As long as I take my insulin, I can eat whatever I want." Proper dietary management is essential in diabetes to maintain stable blood glucose levels.
D. "As I get older, my sugar levels will automatically decrease." Blood glucose levels require active management and do not decrease automatically with age.
