  1. The correct answer is C.

    In this scenario the needle stick is the portal of entry in the chain of transmission. The susceptible host is Felicia, the infectious agent is the blood of the patient on the needle, the needle stick is the portal of entry because it is how the infection entered Felicia, the reservoir is the patient (the host) as that is where the infection lives and the portal or exit would be the vein of the host (where the infection is located).

  2. She could have possibly got HIV from using the same needle that she had just used on the patient. That’s why we don’t reuse needles:/

  3. Portal of entry

    Explanation:

    Portal of entry is the pathway by which the infectious agent reaches the susceptible host. Or that is the way that led a person to be infected by the microorganism that causes an infection. In the case of the above question, Felicia poked herself as she discarded a needle she had just used to administer medication to a patient. This patient was infected with the HIV virus, the needle used in the patient came into contact with the blood and eventually became a vehicle for transmission of the virus. When Felica poked herself with this needle, she contracted the virus. In this case, the needle was the pathway through which the virus hit Felicia. The needle is a portal of entry.

  4. In this scenario the needle stick is the portal of entry in the chain of transmission. The susceptible host is Felicia, the infectious agent is the blood of the patient on the needle, the needle stick is the portal of entry because it is how the infection entered Felicia, the reservoir is the patient (the host) as that is where the infection lives and the portal or exit would be the vein of the host (where the infection is located).

  5. The right option is; C. portal of entry  

    The portal of entry is the route or manner in which an infectious agent enters the body. The portal of entry provides access to susceptible tissues in which the infectious agent can multiply and cause disease. Also, infectious agents can use the same portal of entry as a portal of exit to enter a new host. In the scenario from the question, the needle stick was the portal of entry in the chain of transmission.
