Section 1: Foundational Principles and Core Practices (Questions 1–20)
1. A 68-year-old patient is admitted to Santa Clara Valley Medical Center with fever, cough,
and a maculopapular rash that began on the face and spread downward. The patient returned
from international travel 10 days ago. Which of the following represents the MOST
appropriate immediate infection prevention action?
A. Place the patient in a standard isolation room, apply a surgical mask, and await laboratory
confirmation
B. Immediately place the patient in an airborne infection isolation room (AIIR), have all staff
wear N95 respirators, and notify the Santa Clara County Public Health Department
C. Place the patient in a private room with droplet precautions and collect specimens for
measles PCR
D. Admit the patient to a negative pressure room but allow visitors who are vaccinated against
measles
-detailed answer 100% correct :- B
Rationale: This patient's presentation is highly suspicious for measles—fever, rash, cough,
coryza, and conjunctivitis with recent international travel. Measles requires airborne
precautions, not droplet precautions. The patient should be masked immediately and placed in
an AIIR if available. Healthcare providers should adhere to standard and airborne precautions
regardless of vaccination status. Immediate notification of the local public health department is
required as measles is a reportable disease.
2. According to the California Department of Public Health (CDPH) and Santa Clara County
Public Health recommendations, which of the following patient populations should be
prioritized for admission screening for Candida auris colonization in acute care hospitals?
A. All patients over the age of 65 admitted to any unit
B. Patients admitted from long-term acute care hospitals (LTACHs), ventilator-equipped skilled
nursing facilities (vSNFs), or facilities with known C. auris transmission
C. Patients admitted with a diagnosis of pneumonia or sepsis
D. Patients who have received antibiotics within the previous 30 days
-detailed answer 100% correct :- B
, 3
Rationale: The CDPH and Santa Clara County Public Health recommend admission screening for
patients from LTACHs, vSNF ventilator units, facilities with known transmission, patients with
healthcare exposure outside the U.S., or regions with known C. auris endemicity. Screening
should also be considered for high-acuity units with prolonged lengths of stay. Not all elderly
patients require screening, and antibiotic use alone is not the primary criterion.
3. A healthcare worker sustains a percutaneous injury from a hollow-bore needle used on a
patient with unknown HIV and Hepatitis C status. After immediate first aid, which of the
following represents the CORRECT sequence of actions for post-exposure management at
Santa Clara County facilities?
A. Report to Employee Health within 72 hours, undergo baseline HIV/HCV testing, and initiate
PEP if indicated
B. Immediately report to Employee Health, undergo baseline HIV/HCV testing within hours, and
initiate HIV post-exposure prophylaxis (PEP) within 72 hours if indicated
C. Report to the Emergency Department, undergo HIV testing only, and await results before
initiating any treatment
D. Wash the wound with soap and water, squeeze the site to encourage bleeding, then report to
Employee Health within 24 hours
-detailed answer 100% correct :- B
Rationale: Following a needlestick injury, immediate first aid includes washing the area with
soap and water—squeezing the wound is not recommended. The injury must be reported
promptly to Employee Health, not delayed 72 hours. Baseline HIV/HCV testing should be
obtained, and HIV PEP should be initiated within 72 hours (ideally within hours) if the source
patient is high-risk or unknown.
4. Which of the following statements regarding the Standard Infection Ratio (SIR) used for
tracking healthcare-associated infections in California is CORRECT?
A. The SIR is a raw infection rate that does not account for patient-level differences between
facilities
B. The SIR adjusts for various facility and patient-level factors, allowing for risk-adjusted
comparison of HAI rates across different facilities
C. The SIR is calculated only for surgical site infections and cannot be applied to CLABSI or CDI
D. The SIR is a measure of patient satisfaction with infection prevention efforts
, 4
-detailed answer 100% correct :- B
Rationale: The SIR is a summary measure used to track HAIs at national, state, or local levels
over time. It adjusts for various facility and/or patient-level factors that contribute to HAIs,
allowing for meaningful risk-adjusted comparisons across different facilities. The SIR is applied
to multiple HAI types including CLABSI, CAUTI, SSI, and CDI.
5. A patient with laboratory-confirmed Clostridioides difficile infection (CDI) is placed on
contact precautions. Which of the following represents the CORRECT approach to hand
hygiene for healthcare personnel entering this patient's room?
A. Alcohol-based hand sanitizer is sufficient before and after patient contact
B. Soap and water must be used for hand hygiene after contact with the patient or the patient's
environment
C. Hand hygiene is not required if gloves are worn at all times
D. Either alcohol-based sanitizer or soap and water is acceptable
-detailed answer 100% correct :- B
Rationale: Alcohol-based hand sanitizers are not effective against C. difficile spores. Healthcare
personnel must wash hands thoroughly with soap and water when caring for patients with
known or suspected C. difficile because alcohol does not deactivate spores. This is a critical
distinction for infection prevention in CDI cases.
6. Santa Clara County Public Health mandates masking in healthcare settings during which
specific period, and for what primary purpose?
A. Year-round to prevent all respiratory virus transmission
B. Winter respiratory virus season (November 1 through March 31) to reduce transmission of
influenza, RSV, and COVID-19 during peak circulation
C. Only during declared public health emergencies
D. Only when the county's COVID-19 community level is classified as "high"
-detailed answer 100% correct :- B
Rationale: Santa Clara County Public Health mandates masking during the winter respiratory
virus season from November 1 through March 31. This is designed to reduce transmission of
respiratory viruses including influenza, RSV, and COVID-19 during peak circulation periods. The
mandate applies to healthcare settings to protect patients, staff, and visitors.
