Section 1: Communicable Diseases & Infection Control
1 Impetigo presents as:
A Flat, yellow, crusty or weeping patch on the skin — transmitted by
infected person via hands or clothes
B Spreading rash starting from ears, neck, trunk and extremities
C Severe itching with small raised reddened areas and connecting grayish-
white lines
D Flat, spreading scaly ring-shaped spots with reddish elevated margins
CORRECT ANSWER: A
RATIONALE: Impetigo is a highly contagious bacterial skin infection
producing honey-colored crusted lesions. It spreads through direct contact
with infected persons or contaminated items. Treatment includes daily
bathing with mild soap, and the child may return to care 24 hours after
antibiotic treatment begins. The spreading rash from ears/neck describes
measles; itching with lines describes scabies; ring-shaped spots describe
ringworm.
, 2 Measles (Rubeola) symptoms include:
A Fever, tiredness, cough, runny nose, inflamed eyes worsening over 3 days,
blotchy rash on 4th day — transmitted by nasal/throat secretions
B Flat, yellow crusty patches on the skin
C Painful enlarged lymph nodes with fever rising to 106°F
D Nausea, vomiting, extreme fatigue with jaundice
CORRECT ANSWER: A
RATIONALE: Measles (Rubeola) follows a characteristic progression — 3
days of worsening respiratory symptoms and conjunctivitis, followed by a
blotchy rash appearing on day 4. The cough worsens at night. It is a
reportable disease to the CDC. Children cannot attend school until after the
4th day of rash. MMR vaccination prevents this disease.
3 Mercury poisoning chronic form includes:
A Irritability, excessive saliva, loosened teeth, gum disorders, and slurred
speech
B Spreading rash and fever with swollen glands behind ears
C Tight dry cough becoming severe with vomiting
D Itching and irritation of the anus with tiny white worms
CORRECT ANSWER: A
RATIONALE: Chronic mercury poisoning produces a characteristic syndrome
of neuropsychiatric symptoms (irritability), oral manifestations (excessive
salivation, loosened teeth, gum disorders), and speech impairment. Acute
poisoning causes metallic taste, thirst, nausea, and renal failure. Sources
include industrial waste, seafood, and certain fungicides. Treatment
involves gastric lavage and chelation therapy.
