QUESTIONS AND CORRECT ANSWERS WITH
DETAILED EXPLANATIONS|GUARANTEED
PASS.
BARKLEY
Prepare for the Barkley Shock State AG-ACNP Exam Review with
practice questions covering shock classifications, hemodynamic
monitoring, critical care interventions, pharmacology, patient
assessment, and acute care management. This study guide helps
reinforce essential advanced practice nursing concepts and supports
effective exam preparation. Designed to improve clinical decision-
making and boost confidence in managing critically ill patients.
Suitable for AG-ACNP, nursing, and acute care healthcare students and
professionals.
MULTPLE CHOICE.
Category 1: Pathophysiology & Classification of Shock
(Questions 1–20)
1. A 72-year-old male presents with hypotension, tachycardia, cool clammy
extremities, and decreased urine output. His CVP is low, and PAOP is low. Which
type of shock is most likely?
• A) Distributive
• B) Cardiogenic
• C) Hypovolemic
• D) Obstructive
• Answer: C) Hypovolemic
, Page 2 of 37
• Rationale: Hypovolemic shock is characterized by decreased intravascular volume
leading to low filling pressures (low CVP, low PAOP), tachycardia, cool extremities
(due to vasoconstriction), and hypotension.
2. Which stage of shock is defined by compensatory mechanisms beginning to fail,
with a systolic BP < 90 mmHg and lactic acidosis?
• A) Compensated
• B) Decompensated (Progressive)
• C) Irreversible (Refractory)
• D) Preshock
• Answer: B) Decompensated (Progressive)
, Page 3 of 37
• Rationale: In progressive/decompensated shock, compensatory mechanisms fail,
leading to worsening hypotension, metabolic acidosis, and end-organ
dysfunction.
3. A patient with septic shock has a high cardiac output (CO) but low systemic
vascular resistance (SVR). This is characteristic of which hemodynamic profile?
• A) Cold shock
• B) Warm shock (early distributive)
• C) Cardiogenic shock
• D) Hypovolemic shock
• Answer: B) Warm shock (early distributive)
• Rationale: Early distributive shock (e.g., sepsis, anaphylaxis) shows increased CO
(or normal) with severely decreased SVR, leading to hypotension despite
adequate or high output.
4. Which class of shock is most commonly associated with normal or elevated CVP
and PAOP?
• A) Hypovolemic
• B) Cardiogenic
• C) Distributive
• D) Both B and C
• Answer: D) Both B and C
• Rationale: In cardiogenic shock, elevated filling pressures reflect pump failure. In
distributive shock (specifically septic), CVP/PAOP may be normal or low initially
but can be elevated if fluid resuscitation is given or if right heart failure develops.
5. Which biomarker is most specific for cardiogenic shock due to acute myocardial
infarction?
• A) Procalcitonin
• B) Lactate
, Page 4 of 37
• C) High-sensitivity troponin with dynamic changes
• D) BNP
• Answer: C) High-sensitivity troponin with dynamic changes
• Rationale: While lactate indicates tissue hypoperfusion, troponin rise/fall is
specific for myocardial necrosis. In cardiogenic shock post-MI, troponin is the key
diagnostic marker.
6. A patient with massive pulmonary embolism presents with hypotension,
distended neck veins, and clear lungs. This represents which type of shock?
• A) Cardiogenic
• B) Hypovolemic
• C) Obstructive
• D) Distributive
• Answer: C) Obstructive
• Rationale: Obstructive shock results from physical obstruction to blood flow (e.g.,
PE, tamponade, tension pneumothorax). Distended neck veins with clear lungs
differentiate it from cardiogenic shock (which would have rales/crackles).
7. In the initial stage of shock (compensated), which finding is present?
• A) Overt hypotension
• B) Narrowed pulse pressure
• C) Anuria
• D) Refractory acidosis
• Answer: B) Narrowed pulse pressure
• Rationale: Compensated shock maintains normal systolic BP but diastolic BP rises
due to increased SVR, narrowing pulse pressure. Hypotension is a late sign.
8. Which type of shock is associated with bradycardia (instead of tachycardia) in a
subset of patients?
• A) Septic shock
