Question

The school nurse has provided an instructional session about impetigo to parents of the children attending the school. Which statement, if made by a parent, indicates a need for further instruction?

1) Impetigo is a contagious skin infection caused by bacteria.
2) Impetigo can be treated with antibiotics.
3) Impetigo is caused by a virus.
4) Impetigo is not contagious.

Answer 1

Statement 3) "Impetigo is caused by a virus." indicates a need for further instruction, as impetigo is a bacterial infection caused by Staphylococcus aureus and/or Streptococcus pyogenes, and is highly contagious.

Step-by-step explanation:

The correct answer that indicates a need for further instruction is statement 3) "Impetigo is caused by a virus." This is incorrect because impetigo is a bacterial infection, and stating that it is caused by a virus indicates a misunderstanding of the cause of the condition. Impetigo is commonly caused by Staphylococcus aureus (S. aureus), Streptococcus pyogenes (S. pyogenes), or a co-infection of both. It is important for parents to understand that impetigo is highly contagious and spreads through skin contact or by sharing towels and clothes.

Treatment for impetigo typically involves using topical or oral antibiotics to overcome the bacterial infection. Complications such as acute glomerulonephritis (AGN) can arise, particularly in cases caused by S. pyogenes, thus early identification and proper treatment are crucial. Preventative measures including hygiene practices and not sharing personal items like towels are important to prevent the spread of impetigo.
