Question 1: According to Standard Precautions, healthcare workers should treat
all patients as if they:
A) Are free of infections
B) Carry infections and may be immunocompromised
C) Have only bloodborne pathogens
D) Are allergic to latex
Answer: B) Carry infections and may be immunocompromised
Rationales>..: Standard Precautions require treating all patients as if they carry
infections and are immunocompromised. This universal approach protects both
practitioners and patients by assuming all blood, body fluids, and tissues are
potentially infectious.
Question 2: What are infectious agents that are picked up from one patient and
possibly carried to another patient called?
A) Resident infectious agents
B) Transient infectious agents
,C) Bloodborne pathogens
D) Opportunistic pathogens
Answer: B) Transient infectious agents
Rationales>..: Transient infectious agents are picked up from one patient and
possibly carried to another. Resident infectious agents lodge deeper in the skin and
present additional risk for immunocompromised patients.
Question 3: Which type of infectious agent lodges deeper in the skin and presents
additional risk for immunocompromised patients?
A) Transient infectious agents
B) Bacterial pathogens
C) Resident infectious agents
D) Viral pathogens
Answer: C) Resident infectious agents
Rationales>..: Resident infectious agents lodge deeper in the skin and are of
particular concern for immunocompromised patients.
Question 4: What is the single most important procedure for preventing infection in
a healthcare setting?
A) Wearing gloves
B) Using antiseptic wipes
,C) Hand washing
D) Sterilizing equipment

Question 7: What is the risk of HIV seroconversion after a needlestick injury from a
known carrier?
A) Greater than 50%
B) Approximately 10-20%
C) Less than 1% (approximately 0.3%)
D) 5-10%
Answer: C) Less than 1% (approximately 0.3%)
Rationales>..: The risk of HIV seroconversion following a needlestick injury from a
known carrier is approximately 0.3% (less than 1%). This is significantly lower than
the transmission risk for HBV and HCV.
Question 8: Methicillin-Resistant Staphylococcus Aureus (MRSA) spreads by what
type of contact?
A) Airborne droplets
B) Bloodborne transmission
