1. A patient presents with tachycardia, hypotension, tachypnea, and
cool, clammy extremities. Which type of shock is most consistent with
these findings?
A) Distributive shock
B) Hypovolemic shock
C) Cardiogenic shock
D) Obstructive shock
Answer: C) Cardiogenic shock
Explanation: Cardiogenic shock is characterized by pump failure, leading
to decreased cardiac output and tissue hypoperfusion. The clinical
manifestations include tachycardia (compensatory), hypotension,
tachypnea, and cool, clammy skin due to peripheral vasoconstriction.
Distributive shock typically presents with warm, flushed skin, while
hypovolemic and obstructive shock may also present with cool skin, but
the primary etiology is different.

2. A patient with septic shock is receiving norepinephrine. Which
hemodynamic parameter is the primary target for titration of this
vasopressor?
A) Cardiac output
B) Central venous pressure
C) Mean arterial pressure
D) Pulmonary artery wedge pressure
Answer: C) Mean arterial pressure
Explanation: The primary goal of vasopressor therapy in septic shock is
to restore and maintain adequate mean arterial pressure (MAP) to
ensure perfusion of vital organs. The Surviving Sepsis Campaign
guidelines recommend a target MAP of ≥65 mmHg. Norepinephrine is
titrated to achieve this target. While other parameters are important,
MAP is the direct target for vasopressor titration.
3. In the assessment of a patient with suspected hypovolemic shock,
which finding would be considered a late sign of decompensation?
A) Thirst
B) Tachycardia
C) Orthostatic hypotension
D) Decreased level of consciousness
Answer: D) Decreased level of consciousness
Explanation: Early signs of hypovolemic shock include thirst,
tachycardia, and orthostatic changes as the body attempts to

compensate for decreased volume. A decreased level of consciousness is
a late sign indicating that cerebral perfusion is significantly
compromised, and the body's compensatory mechanisms are failing.
This signifies a critical state requiring immediate intervention.
4. What is the primary pathophysiological mechanism underlying the
development of neurogenic shock?
A) Massive vasodilation and decreased systemic vascular resistance
B) Increased capillary permeability leading to fluid third-spacing
C) Myocardial depression due to inflammatory mediators
D) Obstruction of blood flow in the pulmonary vasculature
Answer: A) Massive vasodilation and decreased systemic vascular
resistance
Explanation: Neurogenic shock results from a loss of sympathetic tone,
often due to spinal cord injury or head trauma. This leads to widespread
vasodilation, a significant drop in systemic vascular resistance (SVR),
and pooling of blood in the venous system. This is fundamentally a
distributive shock, but its mechanism is due to autonomic dysfunction,
not inflammation or vasodilation from sepsis.
5. A patient's hemodynamic monitoring reveals a low cardiac output,
low central venous pressure, and low pulmonary artery wedge
pressure. Which type of shock should the nurse suspect?
A) Cardiogenic shock
B) Hypovolemic shock
, 4|Page
C) Distributive shock
D) Obstructive shock
Answer: B) Hypovolemic shock
Explanation: In hypovolemic shock, there is a decrease in intravascular
volume, leading to decreased preload. This is reflected
hemodynamically as low CVP (right ventricular preload) and low PAWP
(left ventricular preload). The low preload results in decreased stroke
volume and cardiac output. In cardiogenic shock, PAWP is typically
elevated due to pump failure.
6. A patient with anaphylactic shock is exhibiting severe bronchospasm
and angioedema. Which medication should be administered
immediately?
A) Norepinephrine
B) Epinephrine
C) Corticosteroids
D) Diphenhydramine
Answer: B) Epinephrine
Explanation: Epinephrine is the first-line medication for anaphylactic
shock. It has powerful alpha-adrenergic effects to reverse vasodilation
and hypotension, and beta-adrenergic effects to cause bronchodilation
and reduce angioedema. Norepinephrine is a vasopressor but lacks the
strong bronchodilatory effects of epinephrine. Corticosteroids and
antihistamines are adjunctive therapies, but they work too slowly to be
the initial treatment for acute anaphylaxis.
