Question 1

Blood-borne infections include

Accepted Answer

hepatitis

Answer

Hepatitis, particularly Hepatitis B and C, is a well-known blood-borne infection. These viruses are transmitted through contact with infected blood or other body fluids, such as during needle-stick injuries, unprotected sex, or from mother to child. The other options are typically spread through respiratory droplets or direct contact.

Question 2

While Mr. Jones is visiting his wife, you notice that he is sneezing and blowing his nose. What is the best step?

Accepted Answer

Teach him proper hand washing.

Answer

In a healthcare setting, preventing the spread of infection is paramount. Since Mr. Jones is exhibiting symptoms of a respiratory illness, teaching him proper hand washing techniques is the most effective way to reduce the transmission of germs, protecting both his wife and other vulnerable individuals in the facility.

Question 3

While emptying the trash in a client's room, you get stuck by a needle that should have been placed in the sharps container. What is the first thing to do?

Accepted Answer

Wash the site for several minutes.

Answer

In the event of a needle stick injury, the immediate first aid response is to thoroughly wash the affected area with soap and water for several minutes. This action helps to cleanse the wound and reduce the potential for infection. After this immediate step, the incident should be reported and medical evaluation sought.

Question 4

Precautions for a patient in respiratory isolation include all EXCEPT

Accepted Answer

gown

Answer

Respiratory isolation precautions, such as for airborne or droplet-borne diseases, primarily focus on preventing the spread of pathogens through the air. This typically involves a private room, special air handling systems (for airborne), and the use of a mask. A gown is primarily used for contact precautions or when there is a risk of clothing contamination from body fluids, not typically a standard requirement solely for respiratory isolation.

Question 5

When washing your hands, apply the soap

Accepted Answer

after wetting your hands.

Answer

When washing hands, it is essential to wet them first before applying soap. This allows the soap to lather effectively and spread evenly over the entire hand surface. Applying soap to dry hands can make it less effective at creating friction and lifting germs, reducing the overall efficacy of the handwashing process.
