Chapter 8: Health Care and High-Risk Populations

Comprehensive practice flashcards covering Chapter 8: Health Care and High-Risk Populations, including hospital emergency codes, fire attack and evacuation procedures, MRI hazards, nursing home operational challenges, and Mass Casualty Incident (MCI) management.

How frequently should hospital fire drills be scheduled, and how often must they be monitored by the local fire department?

Fire drills should be scheduled monthly and must be monitored at least semiannually by the local fire department.

Under standard hospital emergency alert systems, what does a Code Amber signify and what initial protocol must be initiated?

Code Amber signifies an infant or child abduction. Personnel must immediately take a head count, notify security to cover the outer perimeter, and alert the police while treating the area as a crime scene.

What communication precaution is required in the danger area during a hospital Code Yellow (bomb threat)?

No radio transmissions, cell phone usage, or beeper/pager operation should take place in the danger area because they could potentially trigger an explosive device.

In hospital emergency coding, what situations correspond to Code Red, Code Gray, and Code Silver?

Code Red indicates a fire; Code Gray indicates a security emergency or patient elopement (such as a missing dementia or Alzheimer's patient); Code Silver indicates an active hostage situation.

What do the hospital alerting codes Code Triage and Code Clear (or Condition Green) signify?

Code Triage signifies an external disaster situation (such as an incoming mass casualty incident) requiring significant hospital involvement, while Code Clear or Condition Green indicates the emergency situation has been resolved.

Under what specific clinical conditions do building codes permit electric locking systems to lock means of egress in health care occupancies?

They are permitted in certain occupancies where the clinical needs of persons receiving care require their containment, such as maternity wards using sensor-activated delayed egress locks to prevent infant abduction.

What cooling agent maintains superconductivity in an MRI unit, at what temperature does it operate, and what occurs during a quench?

The unit is immersed in liquid helium operating at temperatures usually below $-255^{\circ}\text{C}$. Quenching expels the liquid helium to the building exterior, where it rapidly heats and expands $760\text{ times}$ in a frigid blast.

Why are standard radio communications ineffective inside an MRI scanner room?

Radio communications are blocked by the copper sheathing installed around the room to prevent outside radio frequency interference.

What federal funding requirement compelled widespread adoption of the NFPA 101 Life Safety Code in US hospitals?

Adoption and compliance with NFPA 101 was mandated as a prerequisite to receive reimbursement under Medicare and Medicaid.

What can the ratio of rescuers to patients reach during an emergency evacuation of a hospital?

The ratio of rescuers to patients can be as great as $2\text{ to }1$, and even higher in intensive care units, critical care units, and nurseries.

According to NFPA statistics from 2006 to 2010, what percentage of health care fires extended beyond the room of origin, and what effect did wet pipe sprinklers have on property damage?

Fire spread beyond the room of origin in only $4\%$ of health care fires, and direct property damage per fire was $61\%$ lower in properties equipped with wet pipe sprinklers.

Why should firefighters attack a multistory hospital fire from the closest stairway or standpipe riser?

Attacking from the closest access point minimizes the number of smoke-proof barrier doors that must be breached with hose-lines, preventing smoke spread and preserving safe havens for patients sheltering in place.

What equipment is responsible for most surgical fires, and what portable extinguisher type is recommended in operating rooms?

Most surgical fires are ignited when high-energy electrosurgical units (ESUs) or lasers accidentally activate in oxygen-enriched atmospheres; carbon dioxide ($\text{CO}_2$) fire extinguishers are recommended to minimize patient and equipment contamination.

What differentiates the staffing and resident profile of an assisted living facility from that of a nursing home?

Assisted living facilities feature private living quarters with minimal staffing for housekeeping and medications; nursing homes involve intensive hands-on care for occupants who are often bedridden, lack mobility, or suffer from dementia or advanced Alzheimer's disease.

What notable unsprinklered nursing home fires in 2003 highlighted the extreme vulnerability of elderly occupants?

The February 2003 fire in Hartford, Connecticut, which killed $16$ residents, and the September 2003 fire in Nashville, Tennessee, which killed $15$ residents.

What nighttime staffing ratio is not uncommon in nursing homes and assisted living facilities?

A ratio of $15\text{ occupants to }1\text{ attendant}$ (or greater).

Why do staff members in nursing homes frequently compound fire incidents with delayed alarms?

Staff members often delay calling the fire department by first investigating the alarm origin themselves, and then become occupied trying to extinguish the fire or rescue residents before alerting responders.

Which nonpatient areas represent high-priority salvage concerns on floors below an active fire in a health care facility?

Pharmacies as well as administrative offices housing vital paper records and computer systems.

What hose-line diameter should be deployed in nursing homes when smaller lines ($1\frac{1}{2}\text{-inch}$ or $1\frac{3}{4}\text{-inch}$) are inadequate for large meeting rooms or auditoriums?

A $2\frac{1}{2}\text{-inch}$ hose-line.

How is a Mass Casualty Incident (MCI) defined?

An incident that occurs when the number of patients exceeds the level of stabilization and care that can normally be provided in a fast and timely manner.

How do operational requirements differ between a Level 1 MCI and a Level 2 MCI?

A Level 1 MCI is managed entirely by the local agency with minimal or no outside response; a Level 2 MCI requires significant outside agency assistance and likely requires transporting patients to regional hospitals or deploying MEDEVAC helicopters.

What were the key facts of the May 12, 2015 Amtrak crash in Philadelphia's Port Richmond neighborhood?

The train traveled in excess of $100\,\text{mph}$ into a $50\,\text{mph}$ curve, killing $8$ passengers and injuring more than $200$ individuals among the $238$ passengers and $5$ crew members.

What do hospital MCI alert designations Level A (or 1), Level B (or 2), and Level C (or 3) signify?

Level A/1 alerts hospitals to a possible MCI so they can activate resources; Level B/2 alerts hospitals to a confirmed MCI and informs them they will receive patients; Level C/3 declares an all-clear indicating the incident is resolved or all patients are transported.

What primary operational capability differentiates a Level 1 trauma center from a Level 4 trauma center?

A Level 1 trauma center provides a full spectrum of surgical specialists and diagnostic equipment on duty $24/7$ and must admit a minimum annual volume of severely injured patients; a Level 4 trauma center provides basic stabilization and treatment in remote areas where no alternative care exists.

What specialized medical countermeasure is carried on mass casualty vehicles specifically for terrorist incidents?

Nerve agent antidote kits designed for rapid administration to both civilian victims and emergency responders.

What role must controllers fulfill during MCI simulated exercises to improve response guidelines?

Controllers must act as objective evaluators who submit written critiques of the operation, offering constructive criticism to identify system failures and update operating guidelines.

What is the operational distinction between a Casualty Collection Area (CCA) and a Casualty Transportation Area (CTA)?

The CCA is the designated site where patients undergo primary triage and initial medical treatment; the CTA is the designated site where stabilized patients are positioned to await immediate ambulance loading and hospital transport.

Why should paramedics not be assigned as ambulance drivers at an MCI staging area?

Paramedics are in high demand and limited supply; they must be assigned to patient care inside the patient compartment, while firefighters, police officers, or other responders serve as transport drivers.

What specific fire apparatus capability do some departments mandate at helicopter landing zones established during an MCI?

An engine company equipped with foam operations capabilities.

When should an incident commander implement a Medical Branch rather than a Medical Group during an MCI?

A Medical Group is sufficient if operations are limited to triage, treatment, and transport within a confined area; a Medical Branch is designated when incident complexity requires significant modular expansion across multiple geographical sectors or specialized functions.
