SECTION 1: STANDARD & TRANSMISSION-BASED
PRECAUTIONS
Question 1
Which situation requires Contact Precautions?
• A) Suspected measles
• B) MRSA in a draining wound
• C) Active pulmonary TB
• D) Influenza infection
Correct Answer: B
Rationale: Contact Precautions are used for organisms spread by direct or indirect
contact (e.g., MRSA, VRE, C. difficile, draining wounds). Measles and TB require
Airborne Precautions; influenza requires Droplet Precautions .
Question 2
Which condition requires Airborne Precautions?
• A) RSV
• B) Pertussis
• C) Varicella (chickenpox)
• D) Adenovirus
,Correct Answer: C
Rationale: Airborne Precautions are required for infections transmitted by small
particle aerosols that remain suspended in air, including Tuberculosis (TB),
Measles, Varicella (chickenpox), and disseminated zoster .
Question 3
Which PPE is required for Droplet Precautions?
• A) N95 respirator
• B) Surgical mask
• C) PAPR only
• D) Shoe covers
Correct Answer: B
Rationale: Droplet pathogens travel short distances (typically within 6 feet) via
large respiratory droplets. A surgical mask is sufficient protection within this
distance. N95 respirators are required for Airborne Precautions .
Question 4
Which of the following are appropriate applications of Transmission-Based
Precautions? Please select all that apply.
• A) Scabies requires Contact Precautions
• B) C. difficile infection requires Contact Precautions
• C) Active pulmonary TB requires Airborne Precautions
• D) Influenza requires Contact Precautions
Correct Answer: A, B, C
Rationale: Scabies and C. difficile require Contact Precautions. Active pulmonary
TB requires Airborne Precautions. Influenza requires Droplet Precautions, not
Contact Precautions .
, Question 5
Standard Precautions apply when caring for which of the following residents?
• A) Only residents with confirmed infections
• B) Only residents with suspected infections
• C) All residents, regardless of suspected or confirmed infection status
• D) Only residents in isolation
Correct Answer: C
Rationale: Standard Precautions apply to all residents, regardless of suspected or
confirmed infection status. This represents the baseline level of infection
prevention that should be used for every patient encounter .
Question 6
Which statement best describes the primary goal of Standard Precautions?
• A) Isolate all patients
• B) Prevent transmission from known and unknown sources of infection
• C) Use N95 respirators for all patients
• D) Eliminate the need for PPE
Correct Answer: B
Rationale: Standard Precautions are designed to prevent transmission of infectious
agents from both recognized and unrecognized sources of infection .
Question 7
What information should NOT be included on signage at room entry indicating a
resident is on Transmission-Based Precautions?
• A) Type of precautions required
