Introduction
This comprehensive assessment is designed to prepare candidates for the HESI Critical Care Exit Examination. It
evaluates the synthesis of foundational nursing theory with advanced applied knowledge essential for managing
complex, unstable patients in high-acuity environments. The exam utilizes a multiple-choice and scenario-based
structure to rigorously test clinical judgment, prioritization, and decision-making skills. Each question emphasizes
real-world application, requiring candidates to interpret hemodynamic data, anticipate complications, and
implement evidence-based interventions. This resource is intended to validate readiness for professional practice
and ensure the delivery of safe, competent, and ethical critical care.
Section One: Questions 1–100
,1. A patient with a severe traumatic brain injury (TBI) is exhibiting signs of increased intracranial pressure
(ICP). The nurse notes a sudden rise in ICP from 18 mmHg to 28 mmHg, accompanied by a significant
decrease in mean arterial pressure (MAP) to 65 mmHg. Which physiological response is the primary concern
at this time?
A. Cerebral vasodilation leading to further increases in ICP.
B. A significant decrease in cerebral perfusion pressure (CPP).
C. Activation of the sympathetic nervous system causing tachycardia.
D. Impaired autoregulation leading to hyperemia.
🟢 B. A significant decrease in cerebral perfusion pressure (CPP).
🔴 RATIONALE: Cerebral Perfusion Pressure (CPP) is calculated as MAP minus ICP (CPP = MAP - ICP). With an
ICP of 28 mmHg and an MAP of 65 mmHg, the CPP is a critically low 37 mmHg (normal is 60-100 mmHg). This
is the primary concern because adequate CPP is essential for cerebral blood flow and oxygenation; a sustained
low CPP leads to cerebral ischemia and irreversible brain damage. Option A is a consequence of low CPP, while
C and D are less immediate concerns compared to the global cerebral ischemia risk from poor perfusion.
2. A patient in the ICU is in cardiogenic shock and is receiving a continuous infusion of dobutamine. The
nurse should primarily monitor for which therapeutic effect?
A. Decreased heart rate.
B. Increased systemic vascular resistance (SVR).
C. Increased cardiac output.
D. Decreased pulmonary artery wedge pressure (PAWP).
🟢 C. Increased cardiac output.
,🔴 RATIONALE: Dobutamine is a synthetic catecholamine with potent inotropic effects, primarily stimulating
beta-1 adrenergic receptors in the heart. This action increases myocardial contractility and stroke volume,
directly leading to an increase in cardiac output. It is not primarily a vasoconstrictor (effect on SVR is minimal),
nor does it significantly decrease heart rate or directly lower PAWP; its primary benefit is to improve forward
flow in the setting of pump failure.
3. A patient's hemodynamic monitoring shows a pulmonary artery wedge pressure (PAWP) of 22 mmHg and
a cardiac index (CI) of 1.8 L/min/m². Based on these findings, which clinical condition is the patient most
likely experiencing?
A. Hypovolemic shock.
B. Septic shock.
C. Cardiogenic shock.
D. Neurogenic shock.
🟢 C. Cardiogenic shock.
🔴 RATIONALE: A PAWP of 22 mmHg is elevated (normal is 6-12 mmHg), indicating fluid overload or left-sided
heart failure. A cardiac index of 1.8 L/min/m² is severely depressed (normal is 2.5-4.0 L/min/m²). The
combination of high filling pressures (elevated PAWP) and low cardiac output is the hallmark of cardiogenic
shock, signifying pump failure. Hypovolemic shock would show a low PAWP, while septic shock typically
presents with a low SVR and a normal or high cardiac output. Neurogenic shock is characterized by hypotension
and bradycardia from loss of sympathetic tone.
4. When providing end-of-life care to a patient who is brain dead, the family is struggling with the decision
to withdraw organ support. Which initial nursing action is most appropriate?
, A. Reassure the family that the healthcare team knows what is best.
B. Provide a quiet, private space for the family to process their grief and ask questions.
C. Immediately call for an ethics consult to force a decision.
D. Explain that continuing support is futile and they must make a choice.
🟢 B. Provide a quiet, private space for the family to process their grief and ask questions.
🔴 RATIONALE: The most appropriate initial nursing action is to create a supportive environment that allows
the family to process the devastating news and express their emotions. This involves facilitating open
communication, answering questions, and providing emotional support. The other options are inappropriate as
they are prescriptive, paternalistic, or force a decision before the family is ready, which can be detrimental to
their coping and grieving process.
5. Which neurological assessment finding is most indicative of a central herniation syndrome?
A. Unilateral dilated, non-reactive pupil.
B. Decerebrate posturing.
C. Contralateral hemiparesis.
D. Cushing's triad (hypertension, bradycardia, irregular respirations).
🟢 D. Cushing's triad (hypertension, bradycardia, irregular respirations).
🔴 RATIONALE: Cushing's triad is a classic, late sign of increased ICP and impending brainstem herniation. It
represents the body's autonomic response to severe brainstem ischemia and is characterized by systemic
hypertension, bradycardia, and an irregular respiratory pattern. Options A, B, and C can be signs of increased
ICP and uncal herniation, but Cushing's triad is the classic and most specific indicator of central (transtentorial)
herniation affecting the brainstem.
