A mother brings her 2-month-old to the well-baby clinic. She states that when she kisses her baby, the infant's skin tastes salty.
The nurse should prepare the mother for what standard diagnostic test to screen for cystic fibrosis (CF)?
Sweat-chloride test.
Faecal-fat test.
Pulmonary-function test.
Potassium chloride test.
The Correct Answer is A
The nurse should prepare the mother for a sweat-chloride test to screen for cystic fibrosis (CF). A sweat- chloride test measures the amount of chloride in the sweat and is used to diagnose CF. CF is a genetic disorder that can cause the body to produce thick, sticky mucus that can clog the lungs and pancreas. One of the symptoms of CF is salty-tasting skin due to an increased amount of salt in the sweat. The other options (B, C, and D) are not standard diagnostic tests for screening for CF.

D. 2 months is also too early for the MMR vaccine.
C. 24 months is slightly beyond the recommended range for the first dose of MMR vaccine, which is given between 12-15 months of age.
Correct Answer is C
Explanation
The nurse should reassure the parents that febrile seizures typically decrease in frequency as the child grows older. Most children outgrow febrile seizures by the age of 5 years.
Ibuprofen is not typically used prophylactically to prevent febrile seizures.
Providing the child with a sponge bath for temperatures over 100.6°F (38.1° C) can help to lower the fever, but it will not necessarily prevent febrile seizures.
Avoiding excessive visual stimuli is not necessary for children with febrile seizures, as this type of seizure is triggered by a fever rather than visual stimuli.
