In front of the ears, one on each side
What is the function of the salivary glands?
To secrete saliva, which has a lubricating function, protects the mucosa of the mouth, contains digestive enzymes, has antimicrobial action, and acts as a buffer
What is the name of the duct through which the submandibular gland drains its mixture of serous and mucous saliva into the mouth?
Submandibular duct (Wharton duct)
What can occur when salivary rates are reduced?
Xerostomia (dry mouth)
Which of the following is NOT a factor considered in the selection of the most appropriate antimicrobial agent?
The patient's insurance coverage
In which scenario would empiric therapy be most necessary?
When the patient is critically ill with an infection of unknown origin
Why might broad-spectrum therapy be needed initially for serious infections?
To cover a wide range of potential pathogens when the identity of the organism is unknown
What influences the choice of drug in the absence of susceptibility data?
The patient's history and site of infection
When is immediate administration of drug(s) prior to bacterial identification and susceptibility testing required?
For acutely ill patients with infections of unknown origin
In the selection of the most appropriate antimicrobial agent, which factor is NOT considered?
The patient's age and gender
Under what circumstances would broad-spectrum therapy be needed initially for serious infections?
When the identity of the organism is unknown or the site makes a polymicrobial infection likely
When is empiric therapy prior to identification of the organism required?
When immediate administration of drug(s) is necessary prior to bacterial identification and susceptibility testing
What influences the choice of drug in the absence of susceptibility data?
The site of infection and the patient's history
Why might acutely ill patients with infections of unknown origin require immediate treatment?
Because waiting for test results may worsen their condition
