ARRT Patient Care Practice Exam

Which diseases can spread through direct or close contact?

1. MRSA only

2. Conjunctivitis only

3. Hepatitis A only

4. MRSA and Conjunctivitis

The correct answer is: MRSA and Conjunctivitis

The correct answer is based on the understanding that both MRSA (Methicillin-resistant Staphylococcus aureus) and conjunctivitis can be transmitted through direct or close contact between individuals. MRSA is a type of bacteria that is resistant to many antibiotics and can be spread through skin-to-skin contact, especially in settings where individuals have open wounds or shared personal items, such as towels or sports equipment. It poses a risk in crowded environments like hospitals or athletic facilities. Conjunctivitis, often referred to as pink eye, is an inflammation of the conjunctiva, which can be caused by bacteria or viruses. It is highly contagious and can spread easily through direct contact with eye secretions, contaminated hands, or shared items like towels and makeup. In contrast, the other choices refer to conditions that are either less commonly spread through direct contact or involve different transmission routes. Hepatitis A, for example, is primarily spread through ingestion of contaminated food or water rather than direct physical contact. Therefore, the combination of MRSA and conjunctivitis as being transmissible through direct or close contact is accurate and highlights the importance of hygiene practices to prevent the spread of these diseases.
