Shock correct answerWhat occurs when perfusion of cells and O2 delivery is inadequate?
Myocardial, Valve, & Dysrhythmia-related issues correct answerWhat causes cardiogenic shock?
Hemorrhage and other fluid losses (vomitting, diarrhea, diaphoresis, intake60)?
ABCs: Open airway (A), Check O2 sats for >95% (B), Assess carotid or femoral pulse (C) correct answerHow would you perform shock assessment (ABCs)?
Weight change, lung sounds (crackles), I & O's correct answerHow do you assess if shock is related to a "volume problem"?
1) ABC's
2) Find out if related to rate, pump, volume, or vascular resistance
3) Identify and treat underlying cause of shock correct answerHow should you prioritize your actions for an individual with shock?
Preload correct answerWhat is the term for the amount of fiber stretch at the end of diastole?
Afterload (min. 60 mmHg) correct answerWhat is the term for the pressure the ventricle must generate for contraction and ejection of blood to occur? (*Vascular Resistance*)
*Heart rate*, blood volume, atrial kick, and sympathetic stimulation
(RA/CVP, PCW, PAD) correct answerWhat influences the preload?
True correct answerT/F: The heart rate has the greatest influence on preload.
Obstruction to blood flow, elasticity and diameter (SVR & PVR) correct answerWhat influences the afterload?
A lab value of the difference between the concentration of serum cations (Na+, K+) and anions (HCO3-, Cl-); A marker for acid-base balance and indicator of perfusion correct answerWhat is "anion gap'?
Ketosis, Lactic Acidosis, Metabolic Acidosis correct answerAn increased anion gap (>16 mEg/L) indicates what?
Assess if the patient's increased HR is a compensatory mechanism correct answerYour patient is showing signs of shock. Your assessment revealed an increased heart rate, indicating the shock is due to a "rate problem". What should you do next?
False; Stress increases glucose level correct answerT/F: All stress hormones cause decreased glucose level.
Complete Open Fracture; the bone is showing through the skin correct answerA patient comes into the ER after slipping on ice. A broken bone in his forearm is protruding through his skin. How would you classify this fracture?
-Displacement
-Blood supply to area
-Immobilization
-Internal fixation devices
-Infection
-Poor nutrition
-Age
-Smoking correct answerWhat are the eight factors that influence fracture healing?
-Reduction
-Immobilization
-Restoration (of normal function) correct answerWhat are the three goals of fracture treatment?
False; Closed reduction is nonsurgical correct answerT/F: Closed reduction is a surgical, manual realignment of bone.
After correct answerDoes immobilization happen before or after a closed reduction of a fracture?
True correct answerT/F: An individual who has open reduction is at risk for infection.
Fracture Reduction (a cast is applied afterward) correct answerWhich fracture treatment facilitates early ambulation?
Cast correct answerWhich fracture treatment allows pt to perform many ADLs?
Sling correct answerWhich fracture treatment is contraindicated with proximal humerus fracture?
c) Fixation correct answerWhich fracture treatment utilizes metal pins and rods to compress the fracture fragments?
a) Sling
b) Cast
c) Fixation
d) All of the above
