An infection control nurse is teaching a class about the transmission of infectious agents. The nurse should include that which of the following diseases is transmitted via airborne transmission? (Select All that Apply.)
Rubeola
Clostridium difficile
Varicella
Tuberculosis
Correct Answer : A,C,D
Choice A Reason:
Rubeola, also known as measles, is highly contagious and spreads through airborne transmission. The virus can remain infectious in the air for up to two hours after an infected person coughs or sneezes. This makes it one of the most easily spread diseases through airborne particles.
Choice B Reason:
Clostridium difficile (C. diff) is primarily transmitted through the fecal-oral route, not through airborne transmission. It spreads via spores that can survive on surfaces and be ingested, leading to infection.
Choice C Reason:
Varicella, or chickenpox, is transmitted through airborne particles. The virus can spread through direct contact with the fluid from the blisters or through respiratory droplets when an infected person coughs or sneezes. This makes it an airborne disease.
Choice D Reason:
Tuberculosis (TB) is caused by Mycobacterium tuberculosis and spreads through the air when an infected person coughs, speaks, or sings. The bacteria can remain suspended in the air for several hours, making TB an airborne disease.
Choice E Reason:
Staphylococcus aureus is not typically transmitted through airborne means. It spreads through direct contact with infected wounds, contaminated surfaces, or through respiratory droplets in some cases. However, it is not considered an airborne disease.

Correct Answer is C
Explanation
Choice A Reason:
Removing the protective gown before removing gloves is incorrect. The correct procedure is to remove gloves first, followed by the gown, to prevent contamination from the gown to the hands.
Choice B Reason:
Using an electronic thermometer is not recommended for clients with Clostridium difficile. Disposable thermometers or dedicated equipment should be used to prevent cross-contamination.
Choice C Reason:
This is the correct answer. The protective gown should be removed before leaving the client’s room to prevent the spread of Clostridium difficile spores to other areas of the healthcare facility. Proper removal and disposal of PPE are crucial in infection control.
Choice D Reason:
Shaking bed linens is incorrect as it can aerosolize Clostridium difficile spores, increasing the risk of spreading the infection. Linens should be carefully handled and placed in a linen bag without shaking.

Choice A Reason:
A healthy stoma should be pink or red, not purple. A purple stoma could indicate compromised blood flow and requires immediate medical attention.
Choice B Reason:
A sigmoid colostomy typically produces formed stool because it is located in the lower part of the colon, where water absorption occurs.

The stoma itself should not be painful after the procedure. Pain may indicate complications such as infection or improper stoma care.
Choice D Reason:
This is the correct answer. A sigmoid colostomy is usually located in the left lower abdomen, as this is where the sigmoid colon is situated.
