COHN S EXAM 2026 STUDY GUIDE COMPLETE
OCCUPATIONAL HEALTH NURSING
CONCEPTS AND PRACTICE QUESTIONS
◉ Skin and Noise Exposures. Answer: To assess the amount of the
contamination use cloth patches or wipes. Noise use sound level
meters.
◉ Exposure Measurements. Answer: Once the proper sampling
device is selected ensure the accurate interpretation of results and
understanding of all possible negative health effects.
◉ Elimination and Substitution - Risk Management and Reduction.
Answer: Entails changing either the workplace, materials, (i.e.
Equipment, Tools, PPE) reducing or eliminating the hazard
◉ Isolation and Containment - Risk Management and Reduction.
Answer: Entails using engineering to physically change the work
environment. (ie. clean room)
◉ Engineering Controls. Answer: It entails the use of physically
changing the environment.
,◉ Work Practice Controls. Answer: Education Programs on safe
practices potential hazards and reduction in exposures i.e. proper
hygiene, safe handling, procedures, and good housekeeping
◉ Administrative Controls. Answer: Changes made for reduction of
the risk to manage the hazard. i.e. reduction of repetitions, reduction
in the # of shifts, things to reduce the hazard
◉ Personal Protection. Answer: EE must have proper EDU on device
and the PPE must be appropriate for the hazard.
◉ Laceration. Answer: Cut or a Tear in the skin
◉ Avulsion. Answer: a piece of skin that is tearing away from the
body
◉ Refer to higher level care (Laceration/Abrasion). Answer: S/S of
infection
Open wound that can't be closed with steri - strips
Materials embedded in the wound
A cut with a loose flap of skin (Avulsion)
Serious cut to hand, fingers, feet, toes or joints
Human or animal bite
Laceration to the face
, Uncontrolled excessive bleeding
Contaminated wound
◉ NIOSH Stress Prevention. Answer: Identify-Design-Implement-
Evaluate
◉ Factors Influencing Stress. Answer: Personal,
Situational/Interpersonal, Organizational, Technological,
Environmental, and Economic Factors
◉ Grab Sampling - Passive Type. Answer: Uses a container to collect
the air of the sample
◉ Integrated Sampling - Active Type. Answer: Uses a filter to collect
the air sample
◉ American Conference of Governmental Industrial Hygiene
Permissible Exposure Limits - Threshold Limit Vales (TLV). Answer:
(8hr/d) (40h/wk)
◉ NIOSH Permissible Exposure Limits - Recommended Exposure
Limits (REL). Answer: (10h/d) (40h/wk)
