Section 1: Cardiovascular Assessment & Diagnostics
Q1. The nurse is reviewing cardiovascular hemodynamics with a group of nursing students.
Which statement accurately describes cardiac output?
A. Cardiac output is the volume of blood ejected from the ventricle with each contraction.
B. Cardiac output is the product of the heart rate and the stroke volume. [CORRECT]
C. Cardiac output is the amount of blood returning to the right atrium each minute.
D. Cardiac output is the pressure the ventricle must overcome to eject blood.
Correct Answer: B
Rationale: Cardiac output (CO) equals heart rate multiplied by stroke volume and normally ranges
from 4 to 8 L/min in adults. Option A defines stroke volume, option C describes venous return, and
option D describes afterload. Accurate interpretation of hemodynamic parameters is a core
expectation of the ATI Learning System RN 3.0 cardiovascular content and the NCLEX-RN
Physiological Adaptation category.

Q2. The nurse auscultates an S3 heart sound in a 68-year-old client admitted with dyspnea and
bilateral crackles. How should the nurse interpret this finding?
A. It indicates fluid volume overload and ventricular distention consistent with heart
failure. [CORRECT]
B. It is a normal variation in adults older than 65 years of age.
C. It indicates decreased ventricular compliance caused by chronic hypertension.
D. It is caused by inflammation of the pericardial sac.
Correct Answer: A
Rationale: An S3, or ventricular gallop, occurs early in diastole during rapid passive ventricular
filling and, in adults older than 35 to 40 years, signals volume overload and failing ventricular
function, which is consistent with this client's crackles and dyspnea. An S4, not an S3, reflects
decreased compliance from hypertension or aortic stenosis, and a pericardial friction rub, not an S3,
accompanies pericarditis. The ATI Learning System RN 3.0 assessment content emphasizes that an
S3 is a normal finding only in children and young adults.
Q3. A nurse is reinforcing teaching for a client scheduled for a transthoracic echocardiogram.
Which statement by the client indicates an understanding of the procedure?
A. A catheter will be threaded into an artery in my groin.
B. I will receive a radioactive tracer through an intravenous line.
C. I must avoid food and fluids for 12 hours before the test.
D. Sound waves will create pictures of my heart, and the test is painless. [CORRECT]
Correct Answer: D
Rationale: A transthoracic echocardiogram is a noninvasive ultrasound study that requires no
catheter, no contrast tracer, and no fasting preparation. A catheter inserted into a groin vessel
describes cardiac catheterization, and a radioactive tracer describes nuclear perfusion imaging. The
ATI Learning System RN 3.0 diagnostic procedure content stresses that clients should accurately
distinguish noninvasive from invasive cardiac testing, a frequent NCLEX-RN testing point.
Q4. Which laboratory finding is most specific for myocardial cell injury?
A. An elevated myoglobin level
B. An elevated C-reactive protein level
C. An elevated cardiac troponin I level [CORRECT]
D. An elevated white blood cell count
Correct Answer: C
Rationale: Cardiac troponin I is found almost exclusively in myocardial tissue, rising within 3 to 4
hours of injury, peaking at about 24 hours, and remaining elevated for 7 to 10 days. Myoglobin rises
earliest but is nonspecific because it is also released from skeletal muscle, while C-reactive protein
and leukocytosis indicate inflammation or infection rather than myocardial necrosis. Laboratory value
interpretation of cardiac biomarkers is a priority focus of the ATI Learning System RN 3.0 and the
NCLEX-RN Reduction of Risk Potential category.

Q5. The nurse is caring for four clients on a telemetry unit. Which client should the nurse
assess first?
A. A client 3 hours post-cardiac catheterization who is requesting lunch
B. A client 1 hour post-cardiac catheterization who reports feeling wet beneath the right
groin dressing [CORRECT]
C. A client 6 hours post-cardiac catheterization whose affected extremity has a capillary
refill of 2 seconds
D. A client who is requesting discharge teaching about resuming driving
Correct Answer: B
Rationale: A sensation of wetness under the dressing suggests active bleeding or rapid hematoma
formation at the arterial puncture site, which can quickly produce life-threatening hypovolemia; the
nurse must expose the site, apply direct pressure, and notify the provider immediately. The other
three clients have stable findings or routine needs that can safely wait. This item reflects the
NCLEX-RN priority-setting framework of assessing unstable physiologic findings first, as reinforced
throughout the ATI Learning System RN 3.0.
Q6. A nurse is obtaining orthostatic vital signs for a client who reports dizziness when standing.
Which technique is correct?
A. Measure blood pressure and heart rate with the client supine, then after 1 to 3 minutes
sitting, and then after 1 to 3 minutes standing. [CORRECT]
B. Measure the blood pressure only after the client has been standing for 10 minutes.
C. Instruct the client to stand up quickly and measure the blood pressure immediately.
D. Measure the blood pressure while the client is lying down and again 30 minutes later
while seated.
Correct Answer: A
Rationale: Orthostatic vital signs are obtained in the supine position and then at 1- to 3-minute
intervals after sitting and standing; a drop of 20 mm Hg or more in systolic pressure or 10 mm Hg or
more in diastolic pressure, usually accompanied by tachycardia or symptoms, is a positive finding.
Waiting 10 minutes after standing can miss a transient drop, and instructing a dizzy client to rise
quickly risks a fall. The ATI Learning System RN 3.0 and the NCLEX-RN test plan emphasize
correct technique when collecting assessment data.

Q7. The nurse is assessing a client for jugular venous distention. To promote accurate findings,
how should the client be positioned?
A. Flat in bed with the head turned toward the side being examined
B. In reverse Trendelenburg position at 60 degrees with the chin raised
C. With the head of the bed elevated 30 to 45 degrees and the head turned slightly away
from the side being examined [CORRECT]
D. In high-Fowler position with the chin touching the chest
Correct Answer: C
Rationale: Jugular venous pulsations are best inspected with the head of the bed elevated 30 to 45
degrees, the head rotated slightly away from the examined side, and tangential lighting; distention
more than 3 to 4 cm above the sternal angle indicates elevated central venous pressure and fluid
overload. A completely flat position distends the neck veins in most people, and extreme neck flexion
or chin elevation obscures the landmarks. Correct cardiovascular assessment technique is a
foundation of the ATI Learning System RN 3.0 blueprint.
Q8. A nurse is explaining hemodynamic concepts to a group of newly licensed nurses. Which
condition increases afterload?
A. Hypovolemia
B. Administration of nitroprusside
C. Decreased blood viscosity
D. Systemic hypertension [CORRECT]
Correct Answer: D
Rationale: Afterload is the resistance against which the left ventricle must eject blood, and systemic
hypertension or arterial vasoconstriction increases it, raising myocardial oxygen demand and
eventually reducing stroke volume. Nitroprusside is a vasodilator that decreases afterload,
hypovolemia primarily decreases preload, and anemia reduces blood viscosity and resistance.
Understanding preload, afterload, and contractility is essential ATI Learning System RN 3.0 content
and supports NCLEX-RN Physiological Adaptation.
