Section 1: Cardiovascular Assessment & Diagnostics
Q1: A nurse is auscultating the heart sounds of a 68-year-old client with heart failure. An extra
heart sound is heard immediately after S2, best appreciated at the apex with the client in the left
lateral position. The sound is low-pitched and is described as a ventricular gallop. How should the
nurse document this finding?
A. S1 accentuation
B. S3 heart sound [CORRECT]
C. S4 heart sound
D. Pericardial friction rub
Correct Answer: B
Rationale: An S3 heart sound (ventricular gallop) is a low-pitched sound heard immediately after S2, best at the
apex with the client in the left lateral position. It is caused by rapid ventricular filling into a noncompliant chamber
and is a classic sign of heart failure (HFrEF) and volume overload. S4 occurs just before S1 (atrial kick) and is
associated with decreased ventricular compliance (HTN, aortic stenosis). S1 accentuation is heard in tachycardia
or hyperdynamic states, while a pericardial friction rub is a high-pitched, scratching, three-component sound. (ATI

Q2: A nurse is preparing to assess jugular venous distension (JVD) on a client admitted with
suspected right-sided heart failure. Which technique is most appropriate for accurate JVD
measurement?
A. Position the client supine flat with the head elevated 30 degrees and identify the highest point
of pulsation in the internal jugular vein [CORRECT]
B. Place the client in high Fowler's position and measure pulsation at the external jugular vein only
C. Position the client in a left lateral decubitus position and inspect for venous pulsations in the
suprasternal notch
D. Have the client sit upright, lean forward, and exhale fully while observing the sternocleidomastoid
area
Correct Answer: A
Rationale: JVD is assessed with the client supine at 30 to 45 degrees of head elevation, observing the internal
jugular vein for the highest pulsation point; JVD >3 cm above the sternal angle indicates elevated right atrial
pressure and right-sided heart failure. The external jugular is less reliable due to valves and tortuosity. Left lateral
and leaning-forward positions are used for auscultation of heart sounds, not JVD assessment. (ATI RN 3.0
Cardiovascular Assessment; NCLEX-RN Health Promotion)
Q3: A client presents to the emergency department with chest pain that started 2 hours ago. Which
cardiac biomarker is most specific and reliable for diagnosing an acute myocardial infarction at
this time?
A. Myoglobin, because it rises within 1-2 hours and is cardiac-specific
B. CK-MB, because it rises within 3-4 hours and is exclusively cardiac-specific
C. Troponin I, because it rises within 3 hours, is highly cardiac-specific, and remains elevated for
7-10 days [CORRECT]
D. LDH, because the LDH1/LDH2 flipped ratio is diagnostic within 24 hours
Correct Answer: C
Rationale: Cardiac troponin I and T are the gold-standard biomarkers for MI because they are highly
cardiac-specific, rise within 3 hours, peak at 24 hours, and remain elevated for 7-10 days. Myoglobin rises early
(1-2 hours) but is not cardiac-specific (skeletal muscle also produces it). CK-MB rises in 3-4 hours but is also
found in skeletal muscle and brain. LDH is largely obsolete for MI diagnosis due to low specificity. (ATI RN 3.0

Q4: A client with dyspnea has a brain natriuretic peptide (BNP) level drawn. The result is 850
pg/mL. Which interpretation by the nurse is correct? (Normal BNP < 100 pg/mL)
A. The result is normal and rules out heart failure as the cause of dyspnea
B. The result indicates mild heart failure; the dyspnea is likely noncardiac
C. The elevated BNP strongly supports heart failure as the cause of the client's
dyspnea [CORRECT]
D. The BNP is elevated but is more consistent with renal failure than heart failure
Correct Answer: C
Rationale: A BNP > 400 pg/mL strongly supports a diagnosis of heart failure as the cause of dyspnea. BNP is
released by ventricular cardiomyocytes in response to ventricular stretch and volume overload; a value of 850
pg/mL is markedly elevated. Values 100-400 pg/mL are equivocal and may occur in renal failure or pulmonary
embolism. While renal failure can mildly elevate BNP, a level this high in a dyspneic client is most consistent with
HF. (ATI RN 3.0 Lab Values; NCLEX-RN Physiological Adaptation)

Q5: A nurse is preparing to apply a 12-lead ECG to a client. Which placement of the V1 chest lead
is correct?
A. Fourth intercostal space at the right sternal border [CORRECT]
B. Fourth intercostal space at the left sternal border
C. Fifth intercostal space at the left midclavicular line
D. Fifth intercostal space at the left anterior axillary line
Correct Answer: A
Rationale: V1 is placed in the fourth intercostal space at the right sternal border. V2 is at the left sternal border
(4th ICS), V4 at the 5th ICS midclavicular line, V3 midway between V2 and V4, V5 at the 5th ICS anterior axillary
line, and V6 at the 5th ICS midaxillary line. Correct lead placement is essential for accurate ECG interpretation
and dysrhythmia diagnosis. (ATI RN 3.0 Diagnostic Tests; NCLEX-RN Reduction of Risk Potential)
Q6: The nurse is caring for four clients on a telemetry unit. Which client should the nurse assess
FIRST?
A. A client 4 hours post-cardiac catheterization reporting back pain and a cool, pale right lower
extremity [CORRECT]
B. A client 24 hours post-cardiac catheterization with a small 2 cm ecchymosis at the femoral insertion
site
C. A client 1 hour post-echocardiogram reporting mild throat discomfort from the transesophageal probe
D. A client who just returned from a stress test reporting muscle soreness in both legs
Correct Answer: A
Rationale: Using the ABC and acute-vs-chronic prioritization framework, the client 4 hours post-cardiac
catheterization with back pain and a cool, pale extremity is showing classic signs of retroperitoneal bleeding or
arterial occlusion - a life-threatening complication requiring immediate assessment and intervention. The cool,
pale limb suggests compromised arterial perfusion. The ecchymosis at 24 hours is an expected finding. Throat
discomfort and muscle soreness are minor and nonurgent. (ATI RN 3.0 Management of Care; NCLEX-RN

Q7: A nurse is teaching a client how to perform orthostatic vital sign measurements at home.
Which sequence should the nurse instruct the client to follow?
A. Measure blood pressure and pulse supine, then immediately standing, and repeat every 5 minutes for
15 minutes
B. Measure blood pressure and pulse supine, then within 1-3 minutes of standing, then again at 3
minutes of standing [CORRECT]
C. Measure blood pressure and pulse seated for 5 minutes, then immediately standing, then after
walking for 5 minutes
D. Measure blood pressure and pulse in left lateral, supine, and Fowler's positions, waiting 10 minutes
between each
Correct Answer: B
Rationale: Orthostatic vital signs are obtained by measuring blood pressure and pulse after the client has been
supine for at least 3-5 minutes, then within 1-3 minutes of standing, and again at 3 minutes standing. A drop in
systolic BP of 20 mmHg or more, a drop in diastolic of 10 mmHg or more, or a heart rate increase of 20 bpm or
more indicates orthostatic hypotension. Immediate standing or walking measurements are inaccurate. (ATI RN

Q8: An 82-year-old client with a long history of hypertension is admitted with dyspnea. The nurse
auscultates an extra heart sound immediately before S1 that is best heard at the apex. How should
the nurse interpret this finding?
A. S3 heart sound indicative of volume overload
B. S4 heart sound indicative of decreased left ventricular compliance from chronic
hypertension [CORRECT]
C. A pericardial friction rub indicative of pericarditis
D. A split S2 indicative of delayed right ventricular depolarization
Correct Answer: B
Rationale: An S4 heart sound is a low-pitched sound heard just before S1 (presystolic), caused by atrial
contraction pushing blood into a stiff, noncompliant ventricle. It is strongly associated with chronic hypertension,
aortic stenosis, and hypertrophic cardiomyopathy. S3 occurs after S2 (early diastole), not before S1. A friction rub
is high-pitched and scratching; a split S2 is heard during inspiration at the upper sternal border. (ATI RN 3.0
Cardiovascular Assessment; NCLEX-RN Physiological Adaptation)
Q9: A client has a pulmonary artery (PA) catheter in place for hemodynamic monitoring. The nurse
notes a sudden, sustained drop in the PA wedge pressure along with hypotension, tachycardia,
and cool, clammy skin. Which action should the nurse take FIRST?
A. Increase the IV fluid infusion rate to maximum and reassess in 30 minutes
B. Re-level and re-zero the transducer, confirm line placement, and verify the waveform before
treating the value [CORRECT]
C. Administer a 500 mL IV bolus of 0.9% normal saline immediately and notify the provider
D. Discontinue the PA catheter and substitute a central venous pressure line for monitoring
Correct Answer: B
Rationale: Before treating any sudden hemodynamic change, the nurse must verify the accuracy of the reading
by re-leveling the transducer to the phlebostatic axis (4th ICS, midaxillary line), re-zeroing, checking line patency,
and confirming waveform quality. Treating an artifact with fluids can cause fluid overload. After verification, if the
wedge pressure is genuinely low indicating hypovolemia, the provider should be notified for ordered fluid
management. Discontinuing the catheter does not address the clinical picture. (ATI RN 3.0 Hemodynamic
Monitoring; NCLEX-RN Safety and Infection Control)
Q10: A client scheduled for an exercise treadmill stress test asks the nurse what to do the morning
of the procedure. Which instruction is most appropriate?
A. Take all prescribed beta-blocker and insulin medications as usual and eat a hearty breakfast
B. Avoid caffeine, nicotine, and heavy meals for at least 3 hours before the test, and hold
beta-blockers only if ordered by the provider [CORRECT]
C. Drink at least 1 liter of water 1 hour before the test to ensure hydration
D. Apply lotion to the chest wall the morning of the test so the electrodes adhere better
Correct Answer: B
Rationale: Before an exercise stress test, clients should avoid caffeine, nicotine, and heavy meals for 3-4 hours
because they can alter heart rate and blood pressure, masking ischemic findings. Beta-blockers may be held per
provider order so the client can achieve the target heart rate; insulin doses may need adjustment. Electrode
adherence is best on clean, dry skin - lotion should be avoided. (ATI RN 3.0 Diagnostic Tests; NCLEX-RN
