A parent and 4-year-old child who recently emigrated from Colombia arrive at the pediatric clinic. The child has a temperature of 102°F, is irritable, and has a runny nose. Inspection reveals a rash and several small, red, irregularly shaped spots with blue-white centers in the mouth. What illness does the nurse suspect the child has?
Correct Answer: A
Rationale: The nurse should suspect measles in this child. The presence of a high fever, irritability, runny nose, rash, and Koplik spots (small, red spots with blue-white centers in the mouth) are classic signs of measles. Measles is a highly contagious viral illness that can lead to serious complications if not managed promptly. Chickenpox (choice B) presents with a different rash pattern and does not typically involve Koplik spots. Fifth disease (choice C) and scarlet fever (choice D) also have distinct clinical presentations and are not characterized by the specific symptoms described in this case.
