MERS-CoV COVID-19 Surge Capacity Crisis Standards DHA / DOH / SCFHS WHO IHR Hajj Preparedness
🌐 WHO Pandemic Phases
1

Inter-Pandemic Period Phase 1–2

No animal influenza viruses circulating in humans. New animal influenza subtypes detected but not in humans. Focus on surveillance, stockpiling, planning.

2

Alert Period Phase 3–5

Human infection with a novel subtype. Limited human-to-human transmission possible. Small clusters; virus not well adapted for sustained spread. Rapid risk assessment, emergency response planning.

3

Pandemic Period Phase 6

Sustained community-level transmission in multiple WHO regions. Full pandemic response: surge capacity, non-pharmaceutical interventions, vaccine roll-out.

4

Transition Period Post-peak

Pandemic activity declining globally. Gradual return to inter-pandemic activities; evaluation, recovery, updating of national pandemic plans.

Epidemic vs Pandemic vs Endemic

Epidemic

Sudden increase in cases of disease above expected rate in a specific geographic area. Time-limited. Example: MERS-CoV hospital clusters in Riyadh.

Pandemic

Epidemic occurring worldwide, crossing international boundaries, usually affecting many people simultaneously. Requires sustained, widespread community transmission. Example: COVID-19 (2020–2022).

Endemic

Disease consistently present at baseline level in a population or geographic area. Predictable occurrence. Example: MERS-CoV circulating in dromedary camel populations in the Arabian Peninsula.

Outbreak Two or more cases linked in time, place, or person — exceeding normal expected numbers.
R0 and Rt: Reproduction Numbers

R0 — Basic Reproduction Number

Average number of secondary cases one infected person generates in a fully susceptible population with no interventions. A biological property of the pathogen-host pair.

Measles R0: 12–18Extremely contagious
COVID-19 (Omicron) R0: 8–15Very high
Influenza (seasonal) R0: 1.2–1.4Moderate
MERS-CoV R0: 0.4–0.9 (community)Below 1 outside hospitals

Rt — Effective Reproduction Number

R0 adjusted for current immunity and interventions. Rt > 1: epidemic growing. Rt = 1: stable. Rt < 1: declining.

Herd Immunity Threshold

Formula: HIT = 1 − (1/R0). For measles (R0=15): HIT = 93%. For COVID-19 delta (R0=6): HIT = 83%. Below HIT, chains of transmission break naturally.

🕌 GCC-Specific Context

MERS-CoV in the Arabian Peninsula

  • Dromedary camels are the primary zoonotic reservoir
  • High-risk exposures: camel farms, camel markets, consuming raw camel milk
  • Healthcare-associated transmission: major contributor to case clusters (Saudi Arabia, South Korea 2015 linked to returning traveller)
  • Strict contact + airborne precautions in any suspected case
  • No licensed vaccine or specific antiviral approved as of 2025

Mass Gathering Risk — Hajj

  • 2–3 million pilgrims annually from 180+ countries
  • Mandatory vaccinations: meningococcal ACWY, seasonal influenza
  • Respiratory infections amplified by crowding, heat stress, sleep deprivation
  • Saudi MOH deploys field hospitals, surge teams, surveillance units during Hajj season

High International Travel Hub Status

  • Dubai, Doha, Riyadh, Abu Dhabi: among world's busiest aviation hubs
  • Rapid importation and exportation of novel pathogens
  • Entry screening protocols mandatory during alert/pandemic phases
  • IHR-compliant points of entry (PoE) at all major airports

GCC Unified Response Structures

  • Saudi MOH: national command centre, field epidemiology programme
  • UAE: National Emergency Crisis and Disasters Management Authority (NCEMA)
  • Qatar: Supreme Committee for Crisis Management
  • Cross-border data sharing protocols under GCC framework
Nursing Implication Any patient presenting with acute respiratory illness + history of camel contact or GCC travel = MERS-CoV rule-out until confirmed otherwise.
🖐️ Standard Precautions — All Patients, Always
Core Principle Standard precautions apply to ALL patients regardless of diagnosis or presumed infection status. They protect both patient and healthcare worker.

Hand Hygiene — WHO 5 Moments

  1. Before touching a patient — prevents transmission TO patient
  2. Before a clean/aseptic procedure — prevents infection at the site
  3. After body fluid exposure risk — protects HCW and environment
  4. After touching a patient — protects HCW and environment
  5. After touching patient surroundings — even if patient not touched

Alcohol-based hand rub (ABHR) preferred. Soap and water when hands visibly soiled or after Clostridium difficile exposure.

Other Standard Precaution Elements

  • PPE: Gloves when touching blood/body fluids; gown if splash risk; mask and eye protection for procedures
  • Sharps safety: Never recap needles two-handed; use safety-engineered devices; sharps disposal containers at point of care
  • Respiratory hygiene/cough etiquette: Mask symptomatic patients at point of entry; tissues; hand hygiene after
  • Environmental cleaning: Routine cleaning of high-touch surfaces; dedicated equipment per patient
  • Waste management: Segregation of clinical vs domestic waste; yellow bags for infectious waste
  • Safe injection practices: One needle, one syringe, one patient
🛡️ Transmission-Based Precautions
TypeRoutePPE RequiredRoomExamples
Contact Direct or indirect contact with patient/environment Gown + gloves (on entry to room); remove before leaving Single room preferred; cohort if necessary MRSA, C. diff, VRE, scabies, norovirus
Droplet Large respiratory droplets (>5 µm); travel <1 metre Surgical mask + eye protection within 1 m; gown + gloves if close contact Single room; door may stay open; curtain acceptable Influenza, pertussis, mumps, meningococcal meningitis, MERS-CoV (standard care)
Airborne Small particle aerosols (<5 µm); travel long distances and remain suspended FFP3/N95 respirator (fit-tested); gown + gloves + eye protection Negative pressure isolation room −2.5 Pa, ≥12 ACH, HEPA, self-closing door TB, measles, varicella, COVID-19 (AGP), MERS-CoV (AGP/suspected)
MERS-CoV Precaution Level Suspected or confirmed MERS-CoV: Contact + Airborne precautions from point of suspicion. Do NOT downgrade until ruled out by PCR. Place in negative pressure room immediately.
Donning (Putting On) Full PPE
  1. Perform hand hygiene (ABHR or soap & water)
  2. Gown — tie at neck, then waist; ensure full coverage
  3. FFP3/N95 respirator — position over nose and chin; fit-check (seal check); no gaps
  4. Eye protection — goggles or face shield; adjust for fit
  5. Gloves — pull over gown cuffs to ensure continuous coverage
Memory Aid: G-R-E-G Gown → Respirator → Eye protection → Gloves
Doffing (Removing) Full PPE — Critical!
Highest contamination risk Most HCW exposures occur during doffing. Perform slowly, with a trained buddy observer.
  1. Gloves — peel off first (most contaminated); do not touch skin; discard
  2. Perform hand hygiene
  3. Gown — unfasten ties; peel away from body/arms rolling outward; discard
  4. Perform hand hygiene
  5. Eye protection — grasp by the clean headband/sides; avoid front; discard or place in decontamination container
  6. Respirator — remove by grasping bottom strap then top strap; do NOT touch front; discard
  7. Perform hand hygiene
⚠️ Aerosol-Generating Procedures (AGPs)
Highest Transmission Risk AGPs generate fine aerosols capable of long-distance transmission. ALWAYS use Airborne + Contact precautions PLUS negative pressure room.

High-Risk AGPs

  • Endotracheal intubation
  • Extubation
  • Bronchoscopy
  • Open suction of airway
  • CPR (chest compressions + bag-mask ventilation)

Moderate-Risk AGPs

  • High-flow nasal oxygen (HFNO) >6 L/min
  • Non-invasive ventilation (BiPAP/CPAP)
  • Nebuliser treatment
  • Tracheostomy care/suctioning
  • Airway oscillation (e.g., PEP devices)

AGP Room Requirements

  • Pressure: −2.5 Pa (negative)
  • Air changes: ≥12 ACH
  • Filtration: HEPA for exhaust air
  • Door: Self-closing; remain shut
  • Antechamber: Preferred for donning/doffing
  • Visitors: Restricted; full PPE required
🏥 Cohort Nursing During Surge

When single rooms are insufficient, cohort nursing groups patients with the same confirmed pathogen together in one ward or zone.

Cohort Nursing Principles

  • Confirmed cases only: Never cohort suspected with confirmed
  • Dedicated staff: Assign nurses/HCWs to cohort zones; no cross-movement
  • Separate equipment: Stethoscopes, BP cuffs, thermometers per cohort
  • Clear zone demarcation: Red (contaminated), Yellow (transition), Green (clean)
  • Negative pressure preferred but not always achievable in surge

Zone Organisation

  • Red Zone: Patient care area — full PPE worn at all times
  • Yellow Zone: Transition/antechamber — donning/doffing area
  • Green Zone: Clean area — staff break room, admin; no PPE
  • Waste moves RED → YELLOW → disposal only
  • Staff move GREEN → YELLOW (don) → RED → YELLOW (doff) → GREEN

CriticalARDS, sepsis, septic shock, multi-organ failure, need for mechanical ventilationRequires ventilationICU; invasive mechanical ventilation; vasopressors

NEWS2 Scoring in COVID-19

  • Validated early warning score adapted for COVID-19 (scale 0–20)
  • 0–4: Low risk — routine monitoring
  • 5–6: Medium risk — 4-hourly monitoring; medical review
  • ≥7: High risk — continuous monitoring; urgent senior review/ICU liaison
  • SpO2 Scale 2 used for patients requiring supplemental O2 (chronic hypercapnic risk: use Scale 1)
  • New confusion (ACVPU score) scores 3 points — highly significant

Awake Proning Protocol

Indication Moderate-severe COVID-19 hypoxaemia (SpO2 <94%) in non-intubated, cooperative patients.
  • Cycle: 2 hours prone → 2 hours lateral (left) → 2 hours lateral (right) → 2 hours supine; repeat
  • Target: 16 hours per day in prone position
  • Use pillows under chest, pelvis, shins to relieve pressure
  • Monitor: SpO2, tolerance, pressure injuries (face, chest, knees)
  • Contraindications: Haemodynamic instability, altered consciousness, facial/thoracic injuries, recent sternotomy
COVID-19 Pharmacological Interventions

Dexamethasone Protocol

  • Dose: 6 mg once daily (oral or IV) for up to 10 days
  • Indication: Requiring supplemental O2 or mechanical ventilation
  • Evidence: RECOVERY trial — 36% reduction in mortality in ventilated patients
  • Do NOT use in mild COVID-19 not requiring O2 — may worsen outcomes
  • Monitor: hyperglycaemia, secondary infection, fluid retention

Anticoagulation

  • Prophylactic LMWH: All hospitalised COVID-19 patients unless contraindicated (bleeding risk)
  • Therapeutic anticoagulation: Confirmed DVT/PE; moderate-severe disease with raised D-dimer and clinical deterioration (per local protocol)
  • Monitor: platelet count, renal function, signs of bleeding

Other Treatments (select regimens)

  • Remdesivir: Moderate disease; early hospitalisation within 7 days of symptom onset
  • Tocilizumab/Baricitinib: Severe/critical with elevated inflammatory markers
  • High-flow nasal oxygen (HFNO): Before escalating to invasive ventilation; titrate to SpO2 92–96%
Post-COVID & Long COVID Assessment

Long COVID Definition (WHO)

Symptoms occurring within 3 months of acute COVID-19 onset, lasting ≥2 months, not explained by an alternative diagnosis.

Common Symptoms

  • Fatigue, post-exertional malaise (PEM)
  • Cognitive impairment ("brain fog")
  • Breathlessness, persistent cough
  • Chest pain, palpitations
  • Joint and muscle pain
  • Anxiety, depression, sleep disturbance

Nursing Assessment

  • 6-minute walk test (6MWT) — functional capacity
  • Spirometry and pulse oximetry on exertion
  • Cognitive screening tools (MoCA)
  • Mental health screening (PHQ-9, GAD-7)
  • Referral pathways: respiratory, cardiology, neuropsychology

MIS-C / MIS-A

Multisystem Inflammatory Syndrome in Children/Adults — rare but severe post-COVID complication. Features: fever, hyperinflammation, organ dysfunction, elevated CRP/ferritin/D-dimer. Requires paediatric critical care input.

🐪 MERS-CoV Nursing — GCC Priority
Case Fatality Rate ~35% MERS-CoV has one of the highest CFRs of any known human coronavirus. Healthcare-associated clusters are the primary driver of human-to-human transmission.

Transmission & Reservoir

  • Reservoir: Dromedary camels (Camelus dromedarius) — MERS-CoV highly prevalent
  • Zoonotic transmission: Contact with camels, nasal discharge, raw camel milk, undercooked camel meat
  • Human-to-human: Mainly nosocomial; limited sustained community spread
  • R0 community: 0.4–0.9 (self-limiting without healthcare amplification)
  • R0 healthcare setting: Can exceed 1 without strict IPC

Clinical Presentation

  • Incubation: 2–14 days (median 5 days)
  • Range: Asymptomatic → severe pneumonia → ARDS
  • GI symptoms common: nausea, vomiting, diarrhoea
  • Renal failure: a distinguishing feature vs COVID-19 and SARS
  • High-risk groups: immunocompromised, diabetes (very common in GCC), chronic renal/lung disease

IPC in MERS-CoV

  • Contact + Airborne precautions — from point of suspicion
  • Negative pressure room; 12 ACH minimum; HEPA filtration
  • FFP3/N95 for all staff entering room
  • Strict doffing protocol with buddy system
  • Limit staff entering room — designate lead nurse
  • Avoid AGPs unless absolutely necessary; if needed: full airborne precautions

Treatment (Supportive)

  • No approved specific antiviral for MERS-CoV as of 2025
  • Supportive: oxygen therapy, mechanical ventilation for ARDS
  • Experimental: convalescent plasma, interferon combinations (clinical trial settings)
  • Corticosteroids: controversial; may delay viral clearance

GCC Hospital Clusters — Key Learning

  • Large hospital cluster: Saudi Arabia 2014 — 255+ cases linked to one hospital
  • South Korea 2015 cluster — traced to single traveller from GCC; 186 cases, 38 deaths
  • Poor triage, overcrowding, delayed IPC = amplification
  • Lessons: triage posters, universal masking, early isolation of fever + respiratory symptoms
📈 Hospital Surge Phases
Conventional

Normal or moderately increased demand. Standard staffing ratios maintained. All services operational. Routine protocols followed.

Normal Operations
Contingency

Significant patient surge. Minor adaptations: postponing elective procedures, increasing staffing, repurposing spaces, reducing documentation burden.

Functionally Equivalent Care
Crisis

System overwhelmed. Care provided may not meet usual standards. Triage decisions required. Ethical framework invoked for resource allocation.

Crisis Standards of Care
⚖️ Crisis Standards of Care (CSC)

Crisis Standards of Care is a formal declaration that a healthcare system cannot provide usual care due to overwhelming demand. It shifts ethical basis from individual-optimised care to population-level best outcomes.

CSC Decision Framework

  • Conventional: Standard protocols; individual patient-centred decisions
  • Contingency: Functionally equivalent care with adapted processes; maximise capacity
  • Crisis: May not meet usual care standards; goal shifts to maximise lives saved across population
  • Transition between levels requires institutional authority and ideally governmental declaration
  • Documentation of CSC status is legally and ethically essential

Ventilator Allocation (Triage)

  • Utilitarian principle: Maximum benefit for most people
  • SOFA score or TISS score commonly used for ICU allocation in crisis
  • Time-limited trials (e.g., 48–72 hours) then reassessment
  • Exclusion criteria defined in advance (not at bedside): irreversible terminal illness, severe multi-organ failure
  • Decisions made by triage team — NOT the bedside nurse alone

Palliative Care Escalation

  • Integral to pandemic response — not a last resort
  • Early goals-of-care conversations with all high-risk patients
  • Comfort-focused care for those not receiving ICU interventions
  • Nurse's role: advance care planning, symptom management, family communication
  • Opioids, anxiolytics for dyspnoea; oral care; dignity in dying

Ethical Principles in Crisis

  • Beneficence: Do good for the most patients possible
  • Non-maleficence: Avoid futile interventions that deny others care
  • Justice: Fair allocation criteria, free from bias (no allocation based on social worth or disability)
  • Autonomy: Respect advance directives; meaningful consent where possible
  • Nurses are patient advocates — escalate concerns about unfair triage
🏗️ ICU Surge & Staff Redeployment

Converting Wards to ICU Capacity

  • Step-down units first: HDU/step-down converted to ICU standard before general wards
  • Portable ventilators and monitoring deployed to general ward bays
  • Operating theatres converted to ICU — anaesthesia ventilators repurposed
  • Elective surgery suspended to free theatre ICU capacity
  • Minimum equipment per bed: ventilator, monitor, infusion pumps, suction

Training Non-ICU Nurses

  • Compressed ICU orientation (typically 3–5 days surge training)
  • Focus areas: ventilator basics, vasopressor titration, arterial line care, CRRT principles
  • Buddy system: 1 experienced ICU nurse paired with 1–2 redeployed nurses
  • Simulation-based rapid skills training preferred
  • Scope of practice adjustments formally documented and legally covered

Surge Staffing Models

  • Team nursing: Small teams with mixed skill levels; experienced nurse leads; tasks distributed by competency
  • Task-based allocation: Specific tasks assigned to specific staff (e.g., one nurse manages all medications for zone)
  • Floating pool: Hospital-wide float pool activated; flexibility between departments
  • Military hospital activation in GCC: armed forces medical staff deployed to civilian hospitals

GCC Pandemic Response Structures

  • Centralised MOH command: Single national command centre; daily ministerial updates
  • Unified protocols: All hospitals follow identical national pandemic nursing protocols
  • Military hospital activation: National Guard, Armed Forces hospitals activated in Saudi Arabia, UAE during COVID-19 peak
  • Private sector integrated into national surge capacity planning
🧠 Burnout & Moral Injury in Pandemic Nursing
Moral Injury Distinct from burnout — caused by perpetrating, witnessing, or failing to prevent actions that violate one's moral code. Common in pandemic triage: "I had to let someone die who might have lived."

Signs of Burnout

  • Emotional exhaustion, cynicism, depersonalisation
  • Reduced sense of personal accomplishment
  • Physical symptoms: insomnia, headaches, immune suppression
  • Absenteeism, increased errors, intention to leave profession
  • Assessed with Maslach Burnout Inventory (MBI)

Signs of Moral Injury

  • Guilt, shame, sense of betrayal
  • Intrusive thoughts about patient deaths
  • Anger at institutional decisions
  • Loss of meaning in clinical work
  • PTSD-like symptoms (flashbacks, avoidance)

Institutional Support Structures

  • Psychological First Aid (PFA): Peer support programmes; trained wellbeing champions on every ward
  • Debriefing sessions: Structured hot and cold debriefs after critical incidents
  • EAP access: 24/7 Employee Assistance Programme; confidential counselling
  • Workload management: Maximum consecutive shift limits; mandatory breaks
  • Leadership visibility: Senior nurses and managers present in the clinical area
  • Recognition programmes: Acknowledgment of extraordinary effort without normalising exploitation
GCC Context Many GCC nursing workforces are internationally recruited (Philippines, India, South Africa). Pandemic placed unique stressors on separated families and visa uncertainty — institutional psychosocial support must be culturally responsive.
💉 Vaccine Nursing — Core Competencies

Cold Chain Management

  • Temperature range: +2°C to +8°C for most inactivated/subunit vaccines; −70°C for mRNA (Pfizer/BioNTech)
  • Continuous temperature monitoring with data loggers; never use a vaccine with temperature excursion before pharmacist/infection control review
  • Transport in validated cold boxes with ice packs; never pack ice directly against vials
  • Vaccines stored in middle shelves of dedicated vaccine fridge — never door shelves
  • VVM (Vaccine Vial Monitor): Check inner square is lighter than outer circle; discard if inner square darker or equal

Anaphylaxis Preparedness

  • Resuscitation equipment immediately available at every vaccination station
  • Adrenaline (epinephrine) 1:1000 — 0.5 mg IM into anterolateral thigh (adult); may repeat after 5 minutes
  • Observe all vaccinees: 15 minutes post-dose standard; 30 minutes for history of anaphylaxis
  • Recognise anaphylaxis: urticaria, angioedema, bronchospasm, hypotension, tachycardia, vomiting within minutes of injection
  • Call emergency team; lay flat with legs raised (unless respiratory compromise); give adrenaline; transfer to ED

Informed Consent Documentation

  • Patient must receive verbal explanation and written information leaflet
  • Document: vaccine name, batch number, site, dose, route, date, consent confirmation, observer
  • Capacity to consent assessed; for minors: parent/guardian consent required; Gillick competency for teenagers
  • In mass vaccination settings: pre-screened consent forms acceptable

AEFI Reporting (Adverse Events Following Immunisation)

  • Classify: minor (local pain, fever), moderate (febrile seizure, severe local reaction), severe (anaphylaxis, hospitalisation, death)
  • Report ALL serious AEFIs within 24 hours to national pharmacovigilance system
  • GCC systems: Saudi FDA (SFDA), UAE Health Authority, QCDD (Qatar)
  • WHO global AEFI reporting via VigiBase
  • Document in patient record and vaccination register independently
🏟️ Mass Vaccination Centre Operations

Site Setup Principles

  • Unidirectional patient flow: registration → screening → vaccination → observation → exit
  • Minimum 15-minute observation area with seating; resus bay at end
  • Signage in multiple languages (Arabic, English, Urdu, Tagalog for GCC)
  • Digital or paper pre-registration to reduce queuing
  • Dedicated lane for elderly, wheelchair users, staff

Throughput Optimisation

  • Throughput formula: number of vaccinators × doses per hour per vaccinator
  • Target: 5–6 minutes per person at vaccination station
  • Bottleneck analysis: identify slowest station (usually registration or screening)
  • Drive-through vaccination centres: highly effective for rapid throughput (used extensively in UAE, Saudi during COVID-19)

Documentation Systems

  • National immunisation registry (e.g., Saudi SFDA vaccine tracker; UAE "Al Hosn" app)
  • Every dose logged: time, vaccinator ID, batch number, site
  • Paper backup mandatory if electronic systems fail
  • End-of-day reconciliation: doses prepared vs administered vs wasted

Vaccine Wastage Reduction

  • Open multi-dose vials only when appointment confirmed
  • Pfizer/Moderna: use opened vials within 6 hours once reconstituted/punctured
  • Record and report wastage per WHO protocol
  • "Zero wastage" policy: seek additional recipients from waiting list before discarding opened vials
🔍 Contact Tracing & Outbreak Investigation

Key Definitions

  • Index case: First identified case in an outbreak — may not be the primary case
  • Primary case: First case who introduced pathogen to the group
  • Close contact: Typically within 1 metre for ≥15 minutes without PPE (varies by pathogen)
  • Quarantine: Separation of exposed individuals who are not (yet) ill — duration = maximum incubation period
  • Isolation: Separation of confirmed or probable cases from well people

Contact Tracing Process

  1. Identify index case; establish symptom onset date
  2. Define infectious period: 48 hours before symptoms to isolation
  3. List all contacts within infectious period; classify as close vs casual
  4. Notify contacts; provide quarantine instructions; arrange testing
  5. Monitor quarantined contacts daily for symptom development

Outbreak Investigation Steps

  1. Verify the diagnosis — laboratory confirmation
  2. Establish a case definition — clinical + epidemiological criteria (suspected/probable/confirmed)
  3. Find cases — active case finding; line list all cases
  4. Describe outbreak — person (who?), place (where?), time (when?) → epidemic curve
  5. Formulate hypothesis — probable source and mode of transmission
  6. Test hypothesis — cohort or case-control study; environmental sampling
  7. Implement control measures — while investigation ongoing
  8. Communicate findings — MOH notification, WHO if IHR criteria met

Attack Rate Calculation

Attack Rate (%) = (Number of cases ÷ Population at risk) × 100

Used to compare risk across groups; guides source identification.

Practice MCQs — Pandemic Nursing

Click an option to reveal whether it is correct. A brief rationale is provided with each answer.

Q1A nurse is caring for a patient with suspected MERS-CoV. Which combination of transmission-based precautions is required?
Correct: C — Contact AND Airborne precautionsMERS-CoV requires the highest level of transmission-based precautions. Airborne precautions include FFP3/N95 respirator and negative pressure room. Contact precautions (gown + gloves) are added due to direct contact risk. Standard precautions alone are insufficient for MERS-CoV.
Q2What is the herd immunity threshold for measles with an R0 of 15?
Correct: C — 93%HIT = 1 − (1/R0) = 1 − (1/15) = 1 − 0.067 = 0.933 = 93%. Measles has one of the highest R0 values of any human pathogen, requiring very high vaccination coverage to achieve herd immunity.
Q3When performing PPE doffing, which item should be removed FIRST?
Correct: A — GlovesGloves are the most contaminated item and are removed first to prevent self-contamination. Doffing order: Gloves → Hand hygiene → Gown → Hand hygiene → Eye protection → Respirator → Hand hygiene. The respirator is removed last as it protects the face and respiratory tract throughout the doffing process.
Q4A mechanically ventilated COVID-19 patient is prescribed dexamethasone. What is the correct dose?
Correct: B — 6 mg once daily for up to 10 daysBased on the RECOVERY trial (Oxford 2020), dexamethasone 6 mg once daily for up to 10 days reduced 28-day mortality by 36% in ventilated COVID-19 patients. This dose should only be used in patients requiring supplemental oxygen or mechanical ventilation.
Q5Which specification is required for a negative pressure isolation room?
Correct: C — −2.5 Pa pressure, ≥12 air changes per hourWHO and CDC standards for airborne infection isolation rooms (AIIRs) require: minimum −2.5 Pa negative pressure relative to corridor, ≥12 air changes per hour (ACH), HEPA filtration of exhaust air, self-closing door. These specifications prevent airborne contaminants from escaping to adjacent areas.
Q6During awake proning for COVID-19 hypoxaemia, what is the recommended cycle duration?
Correct: B — 2 hours prone, alternating lateral/supineThe awake proning cycle is: 2h prone → 2h left lateral → 2h right lateral → 2h supine, targeting 16 hours of prone positioning per 24 hours. Shorter sessions (less than 2 hours) are less effective; longer may increase pressure injury risk without added benefit.
Q7What is the approximate case fatality rate of MERS-CoV?
Correct: D — ~35%MERS-CoV has one of the highest case fatality rates of any human coronavirus at approximately 35% (WHO data). This is significantly higher than SARS-CoV-1 (~10%) and COVID-19 (<3%). The high CFR underscores the critical importance of early isolation and strict IPC measures.
Q8A patient develops urticaria, bronchospasm, and hypotension 8 minutes after receiving influenza vaccine. What is the FIRST action?
Correct: B — Adrenaline 0.5 mg IM anterolateral thighAdrenaline (epinephrine) 1:1000 concentration, 0.5 mg IM into anterolateral thigh, is the FIRST-LINE treatment for anaphylaxis. Do not delay for IV access. Call for help simultaneously. Antihistamines and corticosteroids are adjuncts — they do NOT treat the acute life-threatening features of anaphylaxis.
Q9In Crisis Standards of Care during a pandemic, ventilator allocation triage should primarily be based on:
Correct: C — Short-term survival likelihood (SOFA score)Crisis Standards of Care utilise clinical triage criteria based on likelihood of short-term survival. SOFA (Sequential Organ Failure Assessment) scores objective organ function. Age alone is NOT an ethical basis for triage; social value criteria are explicitly prohibited in most CSC frameworks. First-come-first-served would unfairly disadvantage those who arrive later.
Q10Which vaccine is MANDATORY for all Hajj pilgrims travelling to Saudi Arabia?
Correct: C — Meningococcal ACWYQuadrivalent meningococcal (ACWY) conjugate vaccine is mandatory for all Hajj and Umrah pilgrims. This requirement was instituted following outbreaks of meningococcal meningitis among pilgrims in 1987 (serogroup A) and 2000–2001 (serogroup W135). Saudi Arabia's Ministry of Health strictly enforces this requirement at visa and border control stages.
