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 D
Explanation
Choice A Reason: Night sweats
Night sweats are not typically associated with liver disease. They are more commonly linked to conditions such as infections, hormonal imbalances, or certain cancers1. While liver disease can cause a variety of symptoms, night sweats are not a primary manifestation.
Choice B Reason: Acanthosis nigricans
Acanthosis nigricans is characterized by dark, velvety patches of skin, usually in body folds and creases. It is often associated with insulin resistance, obesity, and certain endocrine disorders. It is not a common manifestation of liver disease.
Choice C Reason: Hemosiderin staining
Hemosiderin staining refers to the deposition of iron in the skin, which can cause a brownish discoloration. This condition is more commonly associated with chronic venous insufficiency or hemochromatosis, a genetic disorder that causes iron overload. It is not a typical symptom of liver disease.
Choice D Reason: Pruritus
Pruritus, or itching, is a common symptom of liver disease. It is often caused by the accumulation of bile salts in the skin due to impaired bile flow, a condition known as cholestasis. This symptom can be particularly distressing for patients and is a significant indicator of liver dysfunction.
Correct Answer is D
Explanation
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.
Choice C Reason:
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.
