NEW QUESTION # 17
In accordance with ASHRAE Standard 170, general hospital Operating Rooms must have a minimum of two return grilles, one of which must be located:
- A. High, and the other low
- B. Adjacent to the anesthetizing location
- C. At breathing height
- D. As far away from the other as practical
Answer: A
Explanation:
Comprehensive and Detailed Explanation:
OR Ventilation: ASHRAE Standard 170, Section 7.4.1, mandates at least two return/exhaust grilles in ORs, with one high and one low. The low grille (near the floor) removes heavier contaminants, while the high grille aids in overall air circulation, supporting laminar flow from ceiling diffusers.
Option Analysis:
A/B: Breathing height or anesthetizing location are not specified in ASHRAE 170.
C: Distance is practical but not the primary requirement.
D: Correct-high and low placement is explicitly required.

NEW QUESTION # 19
In accordance with ASHRAE Standard 170, which of the following areas is required to have a positive pressure relationship?
- A. Nuclear medicine laboratory
- B. Morgue and autopsy area
- C. Physical therapy room
- D. Cystoscopy surgical suite
Answer: D
Explanation:
Comprehensive and Detailed Explanation:
Pressure Requirements: ASHRAE 170, Table 7.1, mandates positive pressure for cystoscopy surgical suites (0.01 in. w.g.) to maintain sterility. Morgue/autopsy (C) and some nuclear medicine areas (D) require negative pressure; physical therapy (B) is typically neutral.
NEW QUESTION # 20
What is the recommended face velocity of Group E diffusers in operating rooms?
- A. 25 to 35 fpm (0.13 to 0.18 m/s)
- B. 50 to 60 fpm (0.25 to 0.31 m/s)
- C. 100 to 110 fpm (0.51 to 0.56 m/s)
- D. 5 to 15 fpm (0.03 to 0.08 m/s)
Answer: A
Explanation:
Comprehensive and Detailed Explanation:
Group E Diffusers: ASHRAE 170 and the HVAC Design Manual recommend 25-35 fpm for laminar flow diffusers in ORs to maintain low turbulence and effective contaminant removal over the surgical field.
NEW QUESTION # 21
Which of the following areas require HEPA-filtered supply air?
- A. Emergency Department Waiting Rooms
- B. Regular Patient Rooms
- C. Protective Environment Rooms
- D. Class A Operating Rooms
Answer: C
Explanation:
Comprehensive and Detailed Explanation:
HEPA Requirement: ASHRAE 170, Section 7.2.2, mandates HEPA-filtered supply air (MERV 17) for Protective Environment Rooms to protect immunocompromised patients. Regular patient rooms (6 ACH), ED waiting rooms (negative pressure), and Class A ORs (15 ACH, MERV 14) do not require HEPA.
