NU 421 Canvas Exam 3
With Solution
Pneumothorax - ANSWER air in the pleural cavity
Tension Pneumothorax - ANSWER a type of pneumothorax in which air that
enters the chest cavity is prevented from escaping
cause of pneumothorax and hemothorax - ANSWER any injury that lets air,
blood, or fluid in pleural space such as rib fracture
What is the difference between a tension pneumothorax and a
pneumothorax - ANSWER A tension pneumothorax is where air is trapped in
the pleural space and cannot escape
Signs and symptoms of pneumothorax - ANSWER asymmetry of the chest,
restlessness, anxiety, respiratory distress, SOB, absence of breath sounds on
one side, decreased cardiac output
LATE SIGN is tracheal deviation and low BP
Diagnosis of tension pneumothorax - ANSWER chest x-ray
Treatment of pneumothorax - ANSWER chest tube
Place patient affected side down to allow for maximum expansion of good
lung
A tension pneumothorax that causes pressure on the great veins can lead to
what - ANSWER Obstructive shock and death
, What is the priority in trauma? - ANSWER Airway & C-Spine
What are A, B, C, and D? - ANSWER A - Airway & C-spine
B- Breathing
C- Circulation (pulses, bleeding, 2 IVs/LR)
D- Disability (neuro exam, motor function)
What do we need to consider for MRI? - ANSWER claustrophobia, metal
implants, pacemakers
What do we need to consider for CT? - ANSWER Renal function
Allergies to iodine, shellfish
What do you do if a patient is going to bleed out before you fix their airway?
- ANSWER CAB! Circulation (fix bleeding), airway, breathing
How much will hemoglobin increase with 1 unit of PRBC? - ANSWER
Hemoglobin goes up by 1
When do rib fractures cause the most pain? - ANSWER During inspiration
In shock do you see tachycardia or bradycardia? - ANSWER Tachycardia
EXCEPT neurogenic shock
Which shock is the only type of shock that is bradycardia? - ANSWER
Neurogenic shock
What is distributive shock and what are the types? - ANSWER systemic
vasodilation leading to decreased cardiac output
- neurogenic shock
