Question 1 • PA Human Anatomy & Physiology A 2026-2027 SMITH IC
Doctors are seeing an alarming increase in the number of cases of tuberculosis (TB) that is resistant to drugs commonly used to treat the disease. TB is difficult to pass to other people without prolonged contact, but it is often fatal if it is not treated. How will doctors most likely respond to someone who has an active case of drug-resistant tuberculosis?
Answer
A
Doctors will not be able to do anything to help someone with drug-resistant TB.
B
Doctors will expose other people to the patient to help those people develop a resistance to TB.
C
Doctors will use other drugs that are known to be able to treat TB, even if they are less effective than the common drugs.
D
Doctors will use the patient to test the effectiveness of new antibiotics that have not been tried on people yet.
Explanation
Drug-resistant TB does not respond to the medicines the bacteria have become resistant to, but other TB medicines may still work. Doctors would choose an effective treatment using those other drugs, even if they are less effective or harder to use. Deliberately exposing people to TB or testing untried antibiotics on a patient would not be the appropriate response.
