ATCN 2020 CHAPTER 3 SHOCK
EXAM(ACTUAL EXAM) WITH CORRECT
ACTUAL QUESTIONS AND CORRECTLY
WELL DEFINED ANSWERS LATEST
ALREADY GRADED A+ 2026
Challenges of advanced Age - ANSWERS-Produces a relative
decrease in sympathetic activity (=deficient receptor
response)
Cardiac compliance decreases with age
Artherosclerotic vascular occlusive disease makes any vital
organs extremely sensitive to even slightest reduction in
blood flow
Pre-existing dehydration
reduced Pulmonary compliance
Decreased diffusion capacity
General weakness of muscles
Glomerular and tubular senescence in the kidney reduces
the elderly ability to preserve volume.
,Kidneys increased sensitivity to drugs - nephrotoxicity
Athletes - Physiologic changes are - ANSWERS-Blood volume
increases 15% to 20%
Increased cardiac output 6 fold
Increased stroke volume
Resting heart rate average 50 bpm
Pregnancy - Physiological changes - ANSWERS-The normal
hypervolemia that occurs with pregnancy means that it
takes a greater amount of blood loss to manifest perfusion
abnormalities in the mother, which may also be reflected in
decreased fetal perfusion.
________________________________________________ is
the most common complication or hemorrhagic shock. -
ANSWERS-Inadequate volume replacement is the most
common complication of hemorrhagic shock.
An ________________________________ is the most
common cause of poor response to fluid therapy. -
ANSWERS-An undiagnosed source of bleeding is the most
common cause of poor response to fluid therapy.
, Lethal Triad of Death - ANSWERS-Coagulopathy
Hypothermia
Acidosis
Obstructive Shock - Consider these diagnosis with injuries
above the diaphragm - ANSWERS-Tension Pneumothorax -
reduces venous return resulting in Obstructive shock
I. Acute Respiratory Distress
II. Sub - Q emphysema
III. Absent Unilateral breath Sounds
IV. Hyper resonance to percussion
V. Tracheal Shift
Cardiac Tamponade - blood in the pericardial sac inhibits
cardiac contractility
Neurogenic shock - list potential causes - ANSWERS-A. Injury
to the cervical or thoracic spinal cord resulting in loss of
sympathetic tone and subsequent vasodilation
B. Isolated intracranial injuries do not cause shock, unless
the brain stem is required
