Prophecy Core Mandatory Part 1, 2 & 3 Practice Mid-Term
Exam (2026/2027)
Question 1
According to CDC guidelines, what is the required method for hand
hygiene when hands are visibly soiled with blood, dirt, or proteinaceous
material?
• A. Using an alcohol-based hand rub for 15 seconds
• B. Washing hands with soap and water for at least 20 seconds
• C. Wiping hands with an antimicrobial wipe
• D. Rinsing hands with hot water only
Correct Answer: B. Washing hands with soap and water for at least 20
seconds
Detailed Rationale: Alcohol-based hand sanitizers are not effective at
penetrating physical dirt or organic material. Mechanical friction with
soap and water is required to remove visible soil.
Question 2
What specific hand hygiene protocol is mandatory after caring for a
patient with a confirmed Clostridioides difficile (C. diff) infection?
• A. Handwashing with soap and water
• B. Using alcohol-based hand rub exclusively
• C. Applying a moisturizing lotion
• D. Rinsing with normal saline
Correct Answer: A. Handwashing with soap and water
,Detailed Rationale: C. diff forms hardy spores that are resistant to the
bactericidal effects of alcohol-based hand sanitizers. Mechanical
handwashing is necessary to physically rinse the spores off the skin.
Question 3
To which patient population do Standard Precautions apply?
• A. Only patients with confirmed communicable diseases
• B. All patients receiving care, regardless of their diagnosis or
presumed infection status
• C. Only immunocompromised patients
• D. Patients admitted to the Intensive Care Unit (ICU)
Correct Answer: B. All patients receiving care, regardless of their
diagnosis or presumed infection status
Detailed Rationale: Standard Precautions are the foundational infection
prevention practices applied to every patient encounter, treating all
blood and body fluids as potentially infectious.
Question 4
What Personal Protective Equipment (PPE) is minimally required prior
to entering the room of a patient on Contact Precautions?
• A. N95 respirator only
• B. Gown and gloves
• C. Surgical mask and eye protection
• D. Sterile gloves and hair net
Correct Answer: B. Gown and gloves
,Detailed Rationale: Contact Precautions prevent the transmission of
epidemiologically important pathogens spread by direct or indirect
contact. A gown and gloves must be donned upon room entry.
Question 5
What type of PPE must a healthcare worker wear when caring for a
patient on Droplet Precautions (e.g., influenza)?
• A. A standard surgical mask when working within 3 feet of the
patient
• B. A full HAZMAT suit
• C. Shoe covers and a sterile gown
• D. Fit-tested N95 respirator
Correct Answer: A. A standard surgical mask when working within 3
feet of the patient
Detailed Rationale: Droplet Precautions prevent the spread of
pathogens transmitted by large respiratory droplets, which travel short
distances. A standard surgical mask is required.
Question 6
What type of patient room is required for a patient placed on Airborne
Precautions (e.g., active tuberculosis, measles)?
• A. A standard double-occupancy room
• B. An Airborne Infection Isolation Room (AIIR) with negative air
pressure
• C. A positive pressure room
, • D. A room located next to the nursing station
Correct Answer: B. An Airborne Infection Isolation Room (AIIR) with
negative air pressure
Detailed Rationale: Negative pressure rooms prevent infectious droplet
nuclei (which remain suspended in the air) from drifting into hospital
corridors when the door is opened.
Question 7
In what order should standard Personal Protective Equipment (PPE) be
DOFFED (removed) to prevent self-contamination, assuming the gown
and gloves are removed separately?
• A. Mask, goggles, gown, gloves
• B. Gloves, goggles/face shield, gown, mask/respirator
• C. Gown, mask, gloves, goggles
• D. Goggles, mask, gloves, gown
Correct Answer: B. Gloves, goggles/face shield, gown, mask/respirator
Detailed Rationale: The most contaminated items (gloves) should be
removed first. The mask or respirator should be removed last, after
leaving the patient's room, to protect the airway.
Question 8
What is the immediate first aid action a healthcare worker must take
after sustaining a contaminated needlestick injury?
• A. Bandage the puncture site tightly
• B. Wash the exposed area immediately with soap and water
