Parents bring their 24-month-old child to the metropolitan area's family care clinic. The reason for the visit is to establish a primary healthcare provider (HCP) for the family’s healthcare maintenance. The child also appears to be suffering from a cold, experiencing rhinorrhea noted to be thick and tenacious and a dry cough which the parent states began a couple of days ago. The nurse suspects that the client may have cystic fibrosis (CF).

Which assessment supports the diagnosis of CF?
a. A fever of 102 ºF (38.9 ºC), inflamed larynx with exudate.
b. Eyes with redness and yellow exudate.
c. Weight loss and delayed growth despite a hearty appetite.
d. A brassy cough with inspiratory stridor.
