Chain of Transmission and Risk Assessment
Scored Test - ANSWERS
Queson 1
Inuenza transmission occurs when the inuenza virus (Infecous Agent), lives and grows in the client’s/paent’s/resident’s
lungs and air passages (Reservoir), exits the respiratory tract through coughing and sneezing (Portal of Exit), travels via
hands, surfaces and droplets (Mode of Transmission), and gains entry through the eyes, nose and mouth (Portal of Entry), to
a Suscepble Host.
Queson 2
The Chain is broken by:
• Wearing gloves to prevent the potenally Infecous Agent from entering the housekeeper’s skin through cuts or
crapes (Portal of Entry)
• Cleaning and disinfecng the oor removes the potenally Infecous Agent (blood) which blocks the Mode of
Transmission (contact)
The person whose blood is on the oor was the Reservoir and the Portal of Exit. They are not in this scenario. Anyone is a
Suscepble Host if they are exposed to another person’s blood. The housekeeper used gloves and did not touch the blood.
Queson 3
Performing a Risk Assessment is the rst step before you carry out any acvity in a health care environment. Gathering
equipment and supplies is necessary but this is not the rst step. Cleaning the cart and informing your supervisor are not
your rst steps.
Queson 4
When performing a personal risk assessment, you need to focus on three main areas: the task you are going to do, what
you know about your client/paent/resident and what you know about the controls in place. It is appropriate to ask how
skilled you are at the task. If this is the rst me you have performed a procedure then you may need addional help to
ensure that it is done safely. Assessing your client/paent/resident’s physical and cognive (mental) status assists your
personal decision making about your need for addional help or personal protecon to complete the task. How your
supervisor evaluates your work is denitely NOT the right queson to ask in your personal Risk Assessment.
Queson 5
Cleaning shared equipment and disposing a soiled dressing into the garbage reduces the risk of transmission of infecon.
Sorng supplies does not reduce the risk of transmission of infecon. Removing gloves and not performing hand hygiene
may increase the risk of transmission of infecon.
