NURS 5315 SHOCK FINAL EXAM TEST LATEST UPDATE WITH ALL
COMPLETE SOLVED SOLUTIONS WITH RATIONALES GRADED A+
VERIFIED 2026- 2027 UPDATE
What is the major cause of organ dysfunction in shock?
A) Increased blood pressure
B) Impaired oxygen and nutrient delivery
C) Enhanced cellular metabolism
D) Excessive waste removal B) Impaired oxygen and nutrient delivery
Rationale: Organ dysfunction results from inadequate oxygen and nutrient supply, leading to
cellular injury and failure.
Which type of shock is most commonly associated with systemic infections?
A) Hypovolemic shock
B) Cardiogenic shock
C) Septic shock
D) Neurogenic shock C) Septic shock
,Rationale: Septic shock is caused by widespread infection, leading to vasodilation, increased
capillary permeability, and decreased perfusion.
Which metabolic process is most impaired during shock?
A) Protein synthesis
B) Glycolysis
C) Oxidative phosphorylation
D) Lipid metabolism C) Oxidative phosphorylation
Rationale: Inadequate oxygen delivery impairs oxidative phosphorylation, leading to decreased
ATP production and reliance on anaerobic metabolism.
What is the primary effect of metabolic acidosis in shock?
A) Increased enzyme function
B) Decreased pH and cellular dysfunction
C) Increased ATP production
D) Enhanced protein synthesis B) Decreased pH and cellular dysfunction
,Rationale: Metabolic acidosis lowers blood pH, impairing enzyme function and cellular activities,
worsening shock progression.
What is the most common cause of hypovolemic shock?
A) Myocardial infarction
B) Hemorrhage
C) Sepsis
D) Spinal cord injury B) Hemorrhage
Rationale: Hypovolemic shock occurs due to significant blood or fluid loss, often from
hemorrhage.
What is the Bohr effect in the context of shock?
A) Increased oxygen binding to hemoglobin
B) Decreased oxygen release to tissues
C) Enhanced oxygen release due to acidosis
D) Reduced hemoglobin production C) Enhanced oxygen release due to acidosis
, Rationale: Acidosis shifts the oxyhemoglobin dissociation curve to the right, promoting oxygen
release to tissues but also increasing tissue hypoxia.
What is the effect of shock on renal function?
A) Increased urine output
B) Decreased urine output (oliguria)
C) Enhanced filtration rate
D) Increased sodium excretion B) Decreased urine output (oliguria)
Rationale: Renal hypoperfusion leads to oliguria, reflecting inadequate blood flow to the
kidneys.
Which compensatory mechanism is activated first in shock?
A) Increased diuresis
B) Baroreceptor activation and tachycardia
C) Increased insulin release
D) Vasodilation B) Baroreceptor activation and tachycardia
