A 6-year-old child has fever, severe headache, and a rash after a tick exposure. Rocky Mountain spotted fever is suspected. Which action should the nurse anticipate?
1Delay antibiotic therapy until the acute and convalescent serology results confirm the diagnosis.
2Request amoxicillin instead of doxycycline because the child has not reached 8 years of age.
3Begin prescribed doxycycline promptly because suspected rickettsial disease is treated in children of any age.✓ Correct answer
4Wait for the rash to spread to the palms and soles before administering an antimicrobial drug.
Explanation
CDC and the American Academy of Pediatrics recommend doxycycline for suspected Rocky Mountain spotted fever in children of all ages. Treatment should begin promptly based on clinical suspicion because delayed therapy increases the risk of severe illness and death. Short courses used for rickettsial disease have not been shown to stain permanent teeth or weaken enamel in young children.
Clinical reasoning Early Rocky Mountain spotted fever can be nonspecific, and a rash may be absent initially. Confirmation testing can remain negative early in illness, so waiting can be dangerous.
Decision rule When a tick exposure and compatible illness create suspicion for a rickettsial disease, start prescribed doxycycline promptly regardless of the child's age.
