CHESP Exam Prep: 200 Practice Questions with
Rationales Covering Regulatory Compliance, Infection
Control, Waste Management, Finance, Administration,
Textile Management, and Design/Construction for 2026
Certification Success.
Section 1: Healthcare Environment and Operations
Q1. A hospital is renovating its surgical suite to reduce
surgical site infections. Which combination of HVAC
parameters is most critical to maintain in the operating
room according to current ASHRAE/CDC guidelines?
A) Positive pressure, 20 air changes per hour,
temperature 20-24°C, relative humidity 30-60%
B) Negative pressure, 15 air changes per hour,
temperature 18-22°C, relative humidity 20-50%
C) Positive pressure, 25 air changes per hour,
temperature 22-26°C, relative humidity 40-70%
D) Neutral pressure, 12 air changes per hour,
temperature 20-24°C, relative humidity 30-50%
☑VERIFIED ANSWER: A
Rationale: Positive pressure prevents contaminated air
,from entering the OR; 20 ACH is the minimum for new
ORs per ASHRAE 170; temperature 20-24°C and humidity
30-60% are standard. Option B uses negative pressure
(incorrect for OR), C has humidity too high (risk of
condensation), D has neutral pressure and low ACH.
Q2. During a Joint Commission survey, a facility is cited
for improper segregation of regulated medical waste
(RMW). Which scenario represents a violation of current
EPA and OSHA standards?
A) Placement of chemotherapy waste in red bags with
the universal biohazard symbol
B) Disposal of empty IV bags (non-hazardous) in clear
plastic bags for municipal waste
C) Use of puncture-resistant sharps containers for used
needles, labeled with biohazard symbol
D) Storage of RMW in a designated area with restricted
access and proper ventilation
☑VERIFIED ANSWER: A
Rationale: Chemotherapy waste is hazardous
pharmaceutical waste, not regulated medical waste; it
must be disposed of in black containers for hazardous
waste per EPA RCRA, not red bags. Option B is correct for
,non-hazardous waste, C is correct for sharps, D is correct
for storage. Red bags are for infectious waste only.
Q3. A healthcare facility is implementing a water
management program to prevent Legionella growth.
According to ASHRAE 188, which is the most critical first
step?
A) Install copper-silver ionization system
B) Conduct a risk assessment of the entire water system
C) Begin routine temperature monitoring at distal outlets
D) Flush all unused water outlets weekly
☑VERIFIED ANSWER: B
Rationale: ASHRAE 188 requires a risk assessment as the
foundational step to identify hazard points before any
control measures. Options A, C, and D are interventions
that may follow the risk assessment, but are premature
without it.
Q4. In a hospital's emergency operations plan, the
Incident Command System (ICS) is activated. Which role
is responsible for ensuring that staff have adequate
personal protective equipment (PPE) during a chemical
spill?
A) Incident Commander
, B) Logistics Section Chief
C) Operations Section Chief
D) Safety Officer
☑VERIFIED ANSWER: B
Rationale: The Logistics Section Chief is responsible for
procuring and distributing resources, including PPE. The
Safety Officer monitors safety conditions but does not
directly provide equipment. The Incident Commander
oversees the entire response, and the Operations Chief
directs tactical operations.
Q5. Evidence-based design (EBD) principles suggest that
single-patient rooms in acute care hospitals reduce
hospital-acquired infections. Which mechanism is the
primary contributor to this reduction?
A) Improved air filtration per room
B) Reduced patient-to-patient transmission via
contaminated surfaces
C) Enhanced hand hygiene compliance due to increased
sink availability
D) Decreased length of stay due to better patient
satisfaction
