A healthcare provider at an urgent care clinic is assessing an adolescent client who has an upper respiratory tract infection. Which of the following findings should the provider recognize as a manifestation of pertussis?
- A. Inflamed throat with exudate
- B. Purulent eye drainage
- C. Dry, hacking cough
- D. Koplik spots on buccal mucosa
Correct Answer: C
Rationale: The correct answer is C: 'Dry, hacking cough.' A dry, hacking cough is a classic manifestation of pertussis. Pertussis typically presents with symptoms of an upper respiratory tract infection, starting with a persistent, severe, and uncontrollable cough that can worsen at night. This cough is often followed by a high-pitched 'whoop' sound as the patient tries to catch their breath, hence the term 'whooping cough.' In contrast, options A, B, and D are not typically associated with pertussis. Inflamed throat with exudate may suggest a bacterial throat infection like streptococcal pharyngitis, purulent eye drainage is more indicative of a bacterial conjunctivitis, and Koplik spots on the buccal mucosa are specific to measles. Therefore, recognizing the dry, hacking cough as a manifestation of pertussis is crucial for early identification and appropriate management of the disease.

Which of the following is the function of macrophages and neutrophils?
- A. Phagocytosis
- B. Complement fixation
- C. Antibody production
- D. Suppression of autoimmunity
Correct Answer: A
Rationale: The function of macrophages and neutrophils is primarily phagocytosis, which is the process of engulfing and digesting pathogens such as bacteria, virus-infected cells, and cellular debris. Phagocytosis is a crucial defense mechanism of the immune system as it helps eliminate harmful invaders and promote tissue repair. Macrophages and neutrophils play key roles in innate immunity by recognizing, ingesting, and destroying pathogens to protect the body from infections.
