Free AAMA Certified Medical Assistant (CMA) Practice Question

A patient presents with a wound presenting signs of infection. The provider requests a Gram stain to be performed on a sample from the wound. What does a positive Gram stain result (purple color) indicate about the type of bacteria present in the wound?

  • The sample indicates the presence of Gram-negative bacteria which have an additional outer membrane but a thinner peptidoglycan layer.

  • The sample contains Gram-positive bacteria that have a thick peptidoglycan layer in their cell walls.

  • The purple color demonstrates bacterial resistance to the staining process, suggesting a need for advanced microbial cultures.
