A 6-year-old child was diagnosed as having streptococcal pharyngitis. At the follow-up visit, the nurse will assess the child for which potential complication?

Rationale: A. Development of rheumatic fever: Rheumatic fever is a serious delayed autoimmune complication that can follow untreated or inadequately treated streptococcal pharyngitis. It affects the heart, joints, and nervous system, making its assessment essential at follow-up. B. Infection that may cause a tooth abscess: A tooth abscess is not related to streptococcal pharyngitis. Dental infections stem from poor oral hygiene or dental trauma, rather than streptococcal throat infections. C. Nephrosis of the kidney: Post-streptococcal glomerulonephritis, not nephrosis, is a potential renal complication of streptococcal infection, characterized by inflammation of the kidney’s filtering units rather than nephrotic syndrome. D. Swollen lymph nodes that obstruct the airway: While lymphadenopathy can occur with throat infections, obstruction of the airway by swollen nodes is rare. Airway obstruction would more likely result from severe tonsillar swelling or abscess formation rather than lymph node enlargement alone.
