FCCS (Fundamentals of Critical Care
Support) Exam Questions And Answers Latest
Update 2025
What is the single most important indicator in critical illness? -
correct answer ✅tachypnea
Beck's Triad -
correct answer ✅hypotension, JVD, muffled heart sounds
- a/w cardiac tamponade
What is the thyromental distance? -
correct answer ✅It is the distance in finger breadths between the
anterior prominence of the thyroid cartilage (adam's apple) and the
tip of the mandible (chin). It is an estimate of the length of the
mandible and the available space anterior to the larynx
What does it mean when the thyromental space is < 3
fingerbreadths? -
correct answer ✅- approx 6 cm
- indicates the larynx might be more anterior and therefore difficult
to visualize during laryngoscopy

Update 2025
** a more acute angulation of the stylet at the distal end of the
endotracheal tube may be helpful.
Patient is apneic w/ a pulse. What do you do? -
correct answer ✅Bag them.
- One handed bag compressions should be delivered 10-20 times
per min. Each compression should take place over 1 second.
** If patient starts spontaneously breathing, try to be synchronous
with their respiratory efforts.
** If/once the patient is breathing easily and adequate Vt are being
inhaled, enough to produce minute ventilation, stop bagging.
What is the goal of manual mask ventilation? -
correct answer ✅to provide adequate minute ventilation: the
product of the tidal volume delivered during each resuscitation bag
compression and the number of compressions per min.
** The total gas volume within most adult resus bags is 1 to 1.5

Update 2025
Bag mask should be connected to ________% oxygen and flow at a
rate of _______ -
correct answer ✅100% oxygen at a rate of 15L/min
HFNC -
correct answer ✅- Uses up to 100% oxygen source
- Provides higher amounts of FIO2 (0.32-1.0) in patients with high
minute ventilation requirements by matching patient's inspiratory
demands and minimizing air dilution
- These devices also can generate PEEP (that is difficult to measure;
can cause barotrauma in theory)
- Flow rates up to 60L/min
- heated and humidified oxygen
NRB -
correct answer ✅- AKA Reservoir Face Mask
- Bag is filled with 100% oxygen from a supply source (tank)
- The flow rate must be adjusted so that the bag remains
completely or partially distended throughout the respiratory cycle
, FCCS (Fundamentals of Critical Care
Support) Exam Questions And Answers Latest
Update 2025
- When the mask is properly applied, oxygen delivery can be
maximized but rarely exceeds a FIO2 of 0.6 to 0.9
- One way flap valves minimize entrapment of room air which
dilutes FiO2
- NRB is a high oxygen high, flow device.
- non humidified oxygen
** commonly used to improve oxygenation in patients with severe
hypoxemia until further eval and treatments are accomplished.
Aerosol Face Mask -
correct answer ✅- This mask has large side holes, the mask itself is
attached to large bore tubing to a nebulize that blends 100%
oxygen and room air to deliver a PRESET FIO2 level (done by dial on
oxygen adapter)
- If the entire aerosol mist disappears from the mask during.
inhalation, the patient's inspiratory flow demands are probably
exceeding the capacity of the nebulizer and room air is being
entrained.
- minimum flow rate = 8L/min
