Endogenous infection
Exogenous infection
Nosocomial infection
Protozoan infection
Which of the following is NOT a protozoan disease?

A patient with a suppressed immune system develops pneumonia from bacteria that are normally harmless in healthy individuals. What type of infection is this?
Opportunistic infection
Nosocomial infection
Exogenous infection
Helminthic infection
A hospital is experiencing an increase in surgical site infections. As a hospital administrator, what strategic steps would you take to reduce these nosocomial infections?
Increase the number of surgeries performed per day
Implement strict sterilization protocols and staff training
Reduce the use of antibiotics
Allow visitors unrestricted access to operating rooms
A patient is diagnosed with malaria after returning from a trip to a tropical country. Using your knowledge of protozoan diseases, explain why malaria is classified as an exogenous infection.
Because it is caused by bacteria from the patient’s own body
Because it is caused by a protozoan transmitted from an external source (mosquito)
Because it is a viral infection
Because it is always acquired in hospitals
A patient with cancer develops a fungal infection after chemotherapy. Using evidence, explain why this is considered an opportunistic infection.
The infection is caused by a virus
The patient’s immune system is weakened, allowing normally harmless fungi to cause disease
The infection is always present in healthy people
The infection is transmitted by insects
A hospital is planning to reduce the rate of nosocomial infections. Which of the following strategies would be most effective, based on evidence and reasoning?
Encouraging patients to self-medicate
Enforcing hand hygiene and sterilization of equipment
Allowing more visitors in patient rooms
Reducing the number of nurses on each shift
A patient develops an infection after surgery, and laboratory tests show the bacteria are part of the patient’s normal skin flora. Using reasoning, classify this infection and explain your answer.
Exogenous infection, because it came from outside the body
Endogenous infection, because it originated from the patient’s own flora
Nosocomial infection, because it was acquired in the community
Protozoan infection, because it was caused by protozoa
