BLSC OSCE Questions Flashcards
Can Descibe to me how you would asses an airway?
Look at rise and fall, look into airway for obstruction
Feel chest and treacheal postion
Listen to sounds of gurgling, crackling, wheezing. Can use stethoscope to listen for air entry
What airway management options do you have?
Stepwise approach, positioning, O2 therapy, adjuncts, NPA, OPA, igels, intubation
Can you describe what a normal X is and some reasons for high/low X
BP
What makes a good Clinical Guidline?
Easily understood, unbiased, up to date,
Why are Chest Commpressions important?
Keep coronoary vessels and brain perfused with oxygen to increase the chance of succesful defibrillations and ensure no brain dmg
What is commpressions fraction? ANd why is it important to have a high fraction?
The proportion of time during a cardiac arrest in which chest commpressinos are being delivered. High fractions means increased perfusion increasing the liklihood of succesful shocks
Describe how Chest Compressions work
Applying a downward pressure will increase thoracic pressure causing forward movement of blood. THe recoil creates a negative pressure allowing the filling of the blood in the heart and the coronary arteries
Describe the negative pressure of breathing
Diagram contracts while external intercostal muscles contract, this causes the ribcage to move up and outward, increasing the volume of the thorax, decreasing the pressure. The pressure compared to outside is now low so it will move down the concentration gradient into the lungs. Opposite = expiration
What are the Repproccussions of Positive Venthilation
Can cause trauma to the lungs, puts pressure on the vena cava causing it to collapse and reduce volume of blood returning to the heart, reducing cardiac output
What is Clinical Frailty?
Pre-existing aspects to a patient as social physiological and metnal that affect our care and their ability to recieve harsh treatment
What tools do we have to manage pain in the Prehospital Setting?
Therapeutic touch, reassurance, positioning, drugs, distraction
Describe the various methods for assesing pain
Actually subjective. 1-10 chart or visual scale or worded scale
Difference between oxygenation and venthilation?
Oxygenation - oxygen reaching the end cells
Ventihilation - gas exchange
What is Type X REespiratory Failure?
Type 1 - hypoxic lack of oxygen
Type 2 - hypercapnic, CO2 can’t be removed fast enough
What is AVPU and what is its weakness’?
Tool to test responsivness. Alert, verbal, pain, unresponsive. confused also. Doesn’t work with dementia patients, or mentally disabled. Could use GCS as alternative
