Scabies.

Mycoplasmal pneumonia.

Tuberculosis.

Scarlet fever.

Answer and Explanation

The Correct Answer is C

The correct answer is C. Tuberculosis.

Choice A rationale:

Scabies is a skin infestation caused by mites, and it does not require airborne precautions. Standard precautions, such as gloves and hand hygiene, are sufficient.

Choice B rationale:

Mycoplasmal pneumonia is typically spread through droplets, and a regular surgical mask is usually adequate for protection.

Choice C rationale:

Tuberculosis (TB) is an airborne disease, and healthcare workers need to wear an N95 respirator to protect themselves from inhaling the bacteria.

Choice D rationale:

Scarlet fever is spread through respiratory droplets, but it does not require airborne precautions. Standard precautions are usually enough.

Correct Answer is C

Explanation

Choice A rationale:

Scabies is a skin infestation caused by the Sarcoptes scabiei mite. While it is contagious, it does not require the use of an N95 respirator mask. Standard precautions, including wearing gloves, are sufficient when caring for a client with scabies.

Choice B rationale:

Mycoplasmal pneumonia is a type of pneumonia caused by the bacteria Mycoplasma pneumoniae. It is typically spread through respiratory droplets and does not require the use of an N95 respirator mask. Standard precautions, including wearing a mask, are appropriate for this condition.

Choice C rationale:

Tuberculosis (TB) is a highly contagious bacterial infection caused by Mycobacterium tuberculosis. TB spreads through the air when an infected person coughs or sneezes. To prevent the inhalation of TB bacteria, healthcare workers should wear N95 respirator masks (or higher level respirators) when caring for clients with active TB disease.

Choice D rationale:

Scarlet fever is a bacterial illness that develops in some people who have strep throat. It is caused by group A Streptococcus bacteria and is typically treated with antibiotics. Scarlet fever does not require the use of an N95 respirator mask. Standard precautions, including wearing gloves and a mask, are appropriate when caring for a client with scarlet fever. Wearing an N95 respirator mask is crucial when caring for clients with airborne infectious diseases like tuberculosis. This type of mask is designed to filter out at least 95% of airborne particles, providing a high level of protection for healthcare workers.

A. Wear a mask when entering the client's room. B. Remove potted plants from the room. C. Allow the client to leave the room every 2 hours. D. Dedicate equipment and supplies for use with the client.

Correct Answer is D

Explanation

Choice A rationale:

Healthcare-associated infections (HAIs) do not necessarily occur due to compromised immunity. HAIs refer to infections that patients acquire while receiving treatment for medical or surgical conditions, and they can happen to individuals with varying levels of immunity.

Choice B rationale:

While infections during therapeutic procedures are a concern, not all healthcare-associated infections occur during such procedures. HAIs can happen in various healthcare settings and not limited to therapeutic procedures.

Choice C rationale:

Inhaling pathogens in a healthcare setting might lead to infections, but not all healthcare-associated infections happen due to inhalation. HAIs can occur through different modes of transmission.

Choice D rationale:

Healthcare-associated infections (HAIs) occur when a patient acquires an infection while receiving care in a healthcare setting, including hospitals. This can involve various sources, such as contaminated medical equipment, surgical procedures, or interactions with healthcare personnel.
