Review questions Flashcards
While transporting a patient from a MVA, en route to the hospital the crew receives word that the CT scanner is down, What does the transporting team do?
Huddle: monitor and modify the plan. it helps to regain situation awareness and make changes to the plan.
What increases Kinetic energy the most and can cause increase risk of injury?
Speed: it increases the kinetic energy by the square of the velocity and can influence the extent of the injury.
A patient’s aorta is torn at the ligamentum arteriosum until it impacts inside the thoracic cavity, what type of impact is this?
Third impact of MVC: Organs continue in motion and are torn away from their attachment.
A 43y old male is being transported to the hospital after an explosion, injuries include fractures to left femur and an amputed right leg, which effect is considered?
Tertiary: results from individual being thrown by blast, types of injuries blunt/penetrating, fractures, traumatic amputation, and closed and open brain injury.
How can the trauma nurse asses the level of bleeding of a trauma patient?
MARCH
Massive hemorrhage
Airway
Respiration
Circulation
Head injury/HypothermiaThe trauma team is attempting to intubate a patient, this attempt is unsuccessful, what should they do?
CONTINUE TO VENTILATE with bag-mask device connected to oxygen at 10-15L
What is the trauma triad of death?
Hypothermia, Acidosis, Coagulopathy
Why would trauma nurse question an order for a foley catheter in a patient that has scrotal ecchymosis
Catheter is contraindicated if urethral transection is suspected.
Why would log rolling be contraindicated in a traumatically injured patient?
This can cause excess movement causing more damage to the patient with suspected spine injury.
What is an indicator that shows adequate cellular perfusion and is useful in guiding resuscitation?
Base deficit
What is an indicator of end-organ perfusion and tissue hypoxia, and can also serve as a guide to resuscitation?
Serum lactate
Signs of Compensated Shock
Anxiety SBP normal DBP rising causing narrowing pulse pressure, Bounding or slightly tachycardic Increased respiratory rate Decreased urinary output
Signs of Decompensated Shock
Deterioration LOC Hypotension Tachycardia Weak & Thready pulses Rapid/shallow respirations Cool, clammy, cyanotic Base excess Serum lactate greated than 2 to 4 mmol/I
Irreversible Shock
Obtunded, comatose hypotension & heart failure Brady w/ dysrhythmias Decreased shallow respirations Pale, cool, clammy skin Organ failure Severe acidosis Coagulapathies w/ petechiae, purpura or bleeding
A patient underwent a Needle Pericardiocentesis, what type of shock did this patient have?
Obstructive Shock: with cardiac tamponade the accumulation of blood impedes diastolic filling which causes decreased cardiac output.
