Question 1: A critically ill patient has a cardiac output of 5.0 L/min, heart rate of 100
bpm, and body surface area of 2.0 m². What is the patient's cardiac index?
A. 1.5 L/min/m²
B. 2.0 L/min/m²
C. 2.5 L/min/m²
D. 3.0 L/min/m²
CORRECT ANSWER: C. 2.5 L/min/m²
Rationale: Cardiac index (CI) is calculated by dividing cardiac output (CO) by body
surface area (BSA). CI = CO/BSA = 5.0 L/min ÷ 2.0 m² = 2.5 L/min/m². The normal range
for cardiac index is 2.5-4.0 L/min/m², making this value at the lower limit of normal.
Cardiac index is a more meaningful parameter than cardiac output alone because it
accounts for patient size.
Question 2: Which hemodynamic parameter best reflects left ventricular preload in
a patient without mitral valve disease?
A. Central venous pressure (CVP)
B. Pulmonary artery systolic pressure
C. Pulmonary artery wedge pressure (PAWP)
D. Right ventricular end-diastolic pressure
CORRECT ANSWER: C. Pulmonary artery wedge pressure (PAWP)
Rationale: Pulmonary artery wedge pressure (PAWP), also called pulmonary capillary
wedge pressure (PCWP), approximates left atrial pressure and left ventricular end-
diastolic pressure (LVEDP) when the mitral valve is functioning normally. This makes
PAWP the best indirect measure of left ventricular preload. CVP reflects right ventricular
preload, not left.
Question 3: A patient in cardiogenic shock has a systemic vascular resistance
(SVR) of 1800 dynes·sec/cm⁵. Which intervention is most appropriate to address
this finding?
,A. Administer norepinephrine
B. Initiate nitroprusside infusion
C. Increase fluid resuscitation
D. Start dopamine at renal dose
CORRECT ANSWER: B. Initiate nitroprusside infusion
Rationale: Normal SVR ranges from 800-1200 dynes·sec/cm⁵. An SVR of 1800 indicates
significant vasoconstriction and increased afterload, which further impairs cardiac
output in cardiogenic shock. Nitroprusside is a potent arterial and venous vasodilator
that reduces afterload and preload, improving cardiac output. Norepinephrine would
further increase SVR, worsening the patient's condition.
Question 4: Which finding on pulmonary artery catheter waveform analysis
indicates proper placement in the pulmonary artery?
A. Pressure tracing shows right atrial waveform
B. Diastolic pressure is lower than systolic with dicrotic notch
C. Pressure tracing shows ventricular waveform with sharp upstroke
D. Wedge pressure tracing appears when balloon is inflated
CORRECT ANSWER: B. Diastolic pressure is lower than systolic with dicrotic notch
Rationale: Proper pulmonary artery placement is confirmed by a waveform showing
systolic pressure (15-30 mmHg), diastolic pressure (8-15 mmHg), and a characteristic
dicrotic notch representing pulmonary valve closure. Right atrial waveform indicates the
catheter is in the RA; ventricular waveform indicates RV placement. Wedge pressure
appears only when the balloon is inflated and the catheter is in a distal branch.
Question 5: A patient with acute decompensated heart failure has a pulmonary
artery wedge pressure of 28 mmHg. Which clinical manifestation is most directly
related to this hemodynamic finding?
A. Hypotension
B. Pulmonary crackles
C. Decreased urine output
D. Tachycardia
CORRECT ANSWER: B. Pulmonary crackles
Rationale: Normal PAWP is 6-12 mmHg. A PAWP of 28 mmHg indicates significant left
ventricular failure with elevated left atrial pressure, causing pulmonary venous
congestion and transudation of fluid into alveoli. This produces pulmonary edema
manifested by crackles on auscultation. While hypotension, decreased urine output,
and tachycardia may occur in heart failure, crackles are most directly related to
elevated PAWP.
Question 6: Which equation correctly calculates mean arterial pressure (MAP)?
,A. (Systolic BP + Diastolic BP) ÷ 2
B. Systolic BP + (2 × Diastolic BP) ÷ 3
C. (2 × Systolic BP + Diastolic BP) ÷ 3
D. Diastolic BP + (Systolic BP − Diastolic BP) ÷ 3
CORRECT ANSWER: D. Diastolic BP + (Systolic BP − Diastolic BP) ÷ 3
Rationale: Mean arterial pressure represents the average pressure in the arteries during
one cardiac cycle. The most accurate formula is MAP = DBP + 1/3 pulse pressure, where
pulse pressure = SBP − DBP. This can also be expressed as (SBP + 2×DBP)÷3. Option D
correctly represents this calculation. Normal MAP is 70-105 mmHg, and values below
60 mmHg may compromise organ perfusion.
Question 7: A patient receiving dobutamine infusion develops new-onset atrial
fibrillation with rapid ventricular response. Which property of dobutamine most
likely contributed to this complication?
A. Alpha-1 agonist activity
B. Beta-1 agonist activity
C. Beta-2 agonist activity
D. Dopamine receptor agonist activity
CORRECT ANSWER: B. Beta-1 agonist activity
Rationale: Dobutamine is primarily a beta-1 adrenergic agonist that increases
myocardial contractility and heart rate. Beta-1 stimulation enhances automaticity and
can precipitate or exacerbate atrial and ventricular arrhythmias, particularly in patients
with underlying cardiac disease. While dobutamine has minor beta-2 activity causing
vasodilation, the arrhythmogenic potential is primarily due to beta-1 effects on cardiac
conduction tissue.
Question 8: Which hemodynamic profile is most consistent with early septic
shock?
A. Low CO, high SVR, low PAWP
B. High CO, low SVR, low PAWP
C. Low CO, high SVR, high PAWP
D. High CO, high SVR, normal PAWP
CORRECT ANSWER: B. High CO, low SVR, low PAWP
Rationale: Early septic (distributive) shock is characterized by profound vasodilation
causing decreased systemic vascular resistance (SVR). Compensatory mechanisms
initially increase cardiac output (CO) through tachycardia and increased stroke volume.
Preload may be low due to capillary leak and relative hypovolemia, resulting in low or
normal PAWP. This contrasts with cardiogenic shock (low CO, high SVR, high PAWP) or
hypovolemic shock (low CO, high SVR, low PAWP).
, Question 9: A patient with an intra-aortic balloon pump (IABP) has the balloon
inflating during late diastole and deflating just before systole. How should the
nurse interpret this timing?
A. Optimal timing for maximal coronary perfusion and afterload reduction
B. Early inflation causing increased myocardial oxygen demand
C. Late deflation increasing left ventricular afterload
D. Incorrect timing requiring immediate repositioning
CORRECT ANSWER: A. Optimal timing for maximal coronary perfusion and
afterload reduction
Rationale: Proper IABP timing involves inflation at the dicrotic notch (onset of diastole)
to augment diastolic pressure and coronary perfusion, and deflation just before systole
to reduce aortic end-diastolic pressure and left ventricular afterload. This timing
maximizes the hemodynamic benefits: improved myocardial oxygen supply and
decreased oxygen demand. Early inflation or late deflation can increase afterload and
myocardial workload.
Question 10: Which laboratory value is most useful for monitoring the
effectiveness of therapy in a patient with cardiogenic shock?
A. Serum creatinine
B. Mixed venous oxygen saturation (SvO₂)
C. Brain natriuretic peptide (BNP)
D. Troponin I
CORRECT ANSWER: B. Mixed venous oxygen saturation (SvO₂)
Rationale: Mixed venous oxygen saturation (SvO₂), measured from the pulmonary artery,
reflects the balance between oxygen delivery and consumption. Normal SvO₂ is 60-
80%. In cardiogenic shock, low SvO₂ indicates inadequate oxygen delivery due to low
cardiac output. Improving SvO₂ toward normal suggests therapy is improving tissue
perfusion. While BNP and troponin provide diagnostic information, SvO₂ is a dynamic
indicator of therapeutic response.
Question 11: A patient has a central venous pressure (CVP) of 18 mmHg. Which
clinical assessment finding would most likely correlate with this elevated value?
A. Flat neck veins in supine position
B. Peripheral edema and hepatic congestion
C. Decreased heart sounds
D. Cool, pale extremities
CORRECT ANSWER: B. Peripheral edema and hepatic congestion
Rationale: Normal CVP is 2-6 mmHg. An elevated CVP of 18 mmHg indicates increased
right-sided heart pressure and impaired venous return, leading to systemic venous
congestion. Clinical manifestations include jugular venous distension, peripheral
