Question 7

Opportunistic infections are more likely to occur in immune-compromised hosts.

Question 8

B) mycosis.
C) helminth.
D) cryptococcosis.

A) diabetes mellitus.
B) immunosuppressive drug therapy.
C) low urine pH.
D) cancer chemotherapy.

Question 15

B) reservoir.
C) fomite.
D) epidemic.

Question 18

Clinical data indicating that a patient has an increased risk of infection include

A) acidic urine.
B) history of allergy to antibiotics.
C) closed surgical wound.
D) white blood cell (WBC) count of 8000/ $\mu$ l.

Question 19

Viruses are composed of either DNA or RNA.

Question 20

When normal resident microorganisms produce disease, the infection is called opportunistic.
