Question

1. infections acquired in healthcare settings are called (a) healthcare - associated infections (hais) (b) chains of infection (cis) (c) microorganism infections (mois) (d) localized infections (lis) 7. the following are links in the chain of infection. which link is broken by wearing gloves, thus preventing the spread of disease? (a) reservoir (place where the pathogen lives and grows) (b) mode of transmission (a way for the disease to spread) (c) susceptible host (person who is likely to get the disease) (d) portal of exit (body opening that allows pathogens to leave) 8. the following are links in the chain of infection. by getting a vaccination for hepatitis b, which link will be affected to prevent a person from getting this disease? (a) reservoir (place where the pathogen lives and grows) (b) mode of transmission (a way for the disease to spread) (c) susceptible host (person who is likely to get the disease) (d) portal of exit (body opening that allows pathogens to leave) 9. how many times can disposable equipment be used before it needs to be discarded? (a) three times (b) one time (c) two times if it is washed in between uses (d) indefinitely if it is sterilized in between

Explanation:

1. Healthcare - associated infections (HAIs) are infections acquired in healthcare settings.
2. Wearing gloves breaks the mode - of - transmission link in the chain of infection as it prevents the transfer of pathogens from one surface or person to another.
3. Vaccination affects the susceptible host by increasing immunity and reducing the likelihood of a person getting the disease.
4. Disposable equipment is designed for single - use to prevent cross - contamination.

Answer:

1. A. Healthcare - associated infections (HAIs)
2. B. Mode of transmission
3. C. Susceptible host
4. B. One time
