A nurse is using personal protective equipment (PPE) before entering the room of a patient with diarrhea and vomiting who is being treated for an intestinal infection.
The nurse most likely needs to use which combination of PPE?

Choice A rationale

Poor personal hygiene can contribute to infections but is not the primary cause of vaginal candidiasis. This condition is typically caused by an overgrowth of Candida albicans, which is not solely related to hygiene.

Choice B rationale

Unprotected sex is not a common cause of vaginal candidiasis. Candida albicans, the yeast responsible for this condition, is usually present in small amounts in the vagina and becomes problematic when it overgrows, which is not typically related to sexual activity.

Choice C rationale

Using bath oils may alter the vaginal flora but is not a primary cause of vaginal candidiasis. The condition results from an imbalance in the normal vaginal environment, often due to other factors such as antibiotics.

Choice D rationale

Long-term antimicrobial therapy is a common cause of vaginal candidiasis. Antibiotics can disrupt the natural balance of bacteria in the vagina, allowing Candida to overgrow and cause infection.

Choice A rationale

Scabies is a parasitic skin infestation caused by mites. It spreads through direct skin-to-skin contact and does not require an N95 respirator. Standard precautions and contact isolation are usually sufficient.

Choice B rationale

Tuberculosis is an airborne infectious disease. An N95 respirator mask is necessary to protect against inhaling airborne droplets that may contain the bacteria, especially in healthcare settings.

Choice C rationale

Scarlet fever is a bacterial infection caused by group A Streptococcus. It spreads through respiratory droplets, but standard surgical masks are usually adequate. An N95 respirator is not required.

Choice D rationale

Mycoplasmal pneumonia is a type of bacterial pneumonia transmitted through respiratory droplets. While it can be contagious, an N95 respirator is generally not necessary unless in specific aerosol-generating procedures. Standard precautions are usually sufficient. .
