Section 1: Complex Cardiovascular Disorders
Q1: A 62-year-old male is admitted with substernal chest pressure radiating to the left jaw, diaphoresis,
and nausea. The 12-lead ECG shows ST-segment elevation in leads II, III, and aVF. Which intervention
must the nurse implement FIRST?
A. Administer sublingual nitroglycerin 0.4 mg every 5 minutes for up to three doses.
B. Obtain a 12-lead ECG, draw cardiac biomarkers, and apply oxygen if SpO2 is below 90%.
C. Establish IV access, administer aspirin 325 mg chewable, and initiate the STEMI activation protocol.
*[CORRECT]*
D. Administer morphine 4 mg IV and place the client in semi-Fowler's position.
Correct Answer: C
Rationale: Inferior STEMI (II, III, aVF) demands immediate reperfusion; the nurse's first actions are IV access, chewable
aspirin 162-325 mg to inhibit platelet aggregation, and activation of the cath lab/STEMI pathway (NCLEX-RN Management of
Care; AHA 2026 STEMI guideline). Nitroglycerin, oxygen titration, and morphine are adjunctive and may worsen hypotension in
right-sided infarcts if given first.

Q2: A client who is 6 hours post-PCI for STEMI suddenly develops coarse crackles in the lung bases, an
S3 heart sound, SpO2 88% on room air, and pink frothy sputum. Blood pressure is 88/52 mmHg. Which
order should the nurse implement FIRST?
A. Administer furosemide 40 mg IV push.
B. Place the client in high-Fowler's position and apply bi-level positive airway pressure (BiPAP).
*[CORRECT]*
C. Increase the IV nitroglycerin infusion rate to 50 mcg/min.
D. Obtain a STAT bedside echocardiogram.
Correct Answer: B
Rationale: Clinical presentation indicates acute decompensated heart failure with cardiogenic shock. The first nursing action is
non-pharmacologic: high-Fowler's plus BiPAP reduces preload and afterload, improves oxygenation, and decreases work of
breathing while awaiting physician orders (NSG 233 heart failure module; QSEN Safety). Furosemide and nitroglycerin may
worsen hypotension.
Q3: A client has a pulmonary artery catheter in place following CABG. The pulmonary capillary wedge
pressure (PCWP) reads 22 mmHg, cardiac output is 3.2 L/min, and SVR is elevated at 1,980
dynes/sec/cm5. The nurse recognizes which hemodynamic profile?
A. Hypovolemic shock
B. Cardiogenic shock *[CORRECT]*
C. Distributive shock
D. Obstructive shock
Correct Answer: B
Rationale: Cardiogenic shock presents with elevated filling pressures (PCWP > 18 mmHg), low cardiac output (< 4 L/min), and
high SVR due to compensatory vasoconstriction. Hypovolemic shock shows low PCWP; distributive shock shows low SVR;
obstructive shock shows equalization of pressures (NSG 233 hemodynamic monitoring module).
Q4: The nurse is caring for a client with a new permanent pacemaker inserted 4 hours ago. Which
assessment finding requires IMMEDIATE physician notification?
A. Mild tenderness at the generator insertion site.
B. Hiccups that persist for more than 10 minutes. *[CORRECT]*
C. Heart rate of 80 bpm paced at 60 bpm.
D. Temperature of 99.2°F (37.3°C).
Correct Answer: B
Rationale: Persistent hiccups after pacemaker insertion suggest diaphragmatic stimulation from lead perforation or malposition,
a medical emergency requiring immediate evaluation (NSG 233 pacemaker module; NCLEX-RN Reduction of Risk). Other
findings are expected.
Q5: A client receiving IV heparin for acute DVT has an aPTT of 110 seconds (control 30-40 sec). Which
order should the nurse anticipate?
A. Increase heparin infusion rate by 100 units/hr.
B. Discontinue heparin and administer protamine sulfate.
C. Hold the next heparin dose and decrease the infusion rate per protocol. *[CORRECT]*
D. Administer vitamin K 10 mg IV.
Correct Answer: C
Rationale: An aPTT > 100 sec places the client at high bleeding risk. The nurse should hold heparin, notify the provider, and
reduce the infusion rate per the institution's weight-based nomogram. Protamine is reserved for serious bleeding; vitamin K
reverses warfarin, not heparin (NSG 233 anticoagulation module).

Q6: Which rhythm on the cardiac monitor requires immediate synchronized cardioversion per ACLS
algorithm?
A. Atrial fibrillation with a ventricular response of 110 bpm and a systolic BP of 118/72.
B. Atrial flutter with a ventricular rate of 150 bpm, BP 78/44, and altered mental status. *[CORRECT]*
C. Sinus tachycardia at 130 bpm in a febrile client.
D. Ventricular paced rhythm at 70 bpm with BP 122/78.
Correct Answer: B
Rationale: Unstable tachyarrhythmia (hypotension, altered mental status) requires immediate synchronized cardioversion. Stable
atrial fibrillation can be rate-controlled pharmacologically; sinus tachycardia requires treatment of the underlying cause (NSG
233 ACLS/dysrhythmia module; AHA ACLS 2026).
Q7: A client postoperative day 2 from a mitral valve replacement with a mechanical valve asks why they
must take warfarin for the rest of their life. The nurse's BEST response is:
A. Mechanical valves do not require lifelong anticoagulation; only biological valves do.
B. Mechanical valves are thrombogenic and require lifelong warfarin with a target INR of 2.5-3.5.
*[CORRECT]*
C. Warfarin prevents infective endocarditis from developing on the valve.
D. Lifelong warfarin is only needed for the first 6 months postoperatively.
Correct Answer: B
Rationale: Mechanical valves are highly thrombogenic, requiring lifelong anticoagulation with a goal INR of 2.5-3.5 (or 3.0-4.0
for mitral position in some references). Biological valves only need short-term anticoagulation (NSG 233 valvular disorders;
AHA/ACC 2020 Valvular Guideline).
Q8: The nurse notes a client's PA catheter wedge pressure is 4 mmHg, cardiac index is 2.0 L/min/m2, and
SVR is 1,050 dynes/sec/cm5. The client is post-operative day 1 from CABG. Which action is most
appropriate?
A. Administer IV metoprolol 5 mg.
B. Administer a 250 mL isotonic fluid bolus and reassess. *[CORRECT]*
C. Increase dobutamine infusion.
D. Administer IV furosemide 20 mg.
Correct Answer: B
Rationale: Low PCWP (< 6 mmHg), low cardiac index, and low-normal SVR indicate hypovolemia post-cardiac surgery. A
fluid challenge with isotonic crystalloid is the first-line intervention to restore preload and cardiac output (NSG 233
hemodynamic monitoring module). Beta-blockers, diuretics, and inotropes would worsen the condition.
Q9: A client with heart failure has a BNP of 1,820 pg/mL, weight gain of 4 pounds in 3 days, and bilateral
crackles. The nurse understands which pathophysiologic process is occurring?
A. Volume overload and increased ventricular wall stress *[CORRECT]*
B. Decreased intravascular volume and decreased preload
C. Right ventricular infarction with cardiogenic shock
D. Acute pericardial tamponade
Correct Answer: A
Rationale: Elevated BNP (> 400 pg/mL) with weight gain and crackles indicates acute decompensated heart failure from volume
overload. BNP is released from overstretched ventricles; the higher the value, the more severe the wall stress and fluid overload
(NSG 233 heart failure; QSEN Evidence-Based Practice).

Q10: A client presents with sudden severe tearing chest pain radiating to the back, BP 180/110 in the right
arm and 92/60 in the left arm. Which action is the priority?
A. Administer aspirin 325 mg PO.
B. Initiate two large-bore IVs, prepare for CT angiography, and administer IV esmolol. *[CORRECT]*
C. Administer IV morphine 4 mg and nitroglycerin.
D. Activate the STEMI team for cath lab.
Correct Answer: B
Rationale: Systolic BP differential > 20 mmHg with tearing pain indicates aortic dissection. Priority is heart rate and BP control
with IV beta-blocker (esmolol) before vasodilators, plus imaging to confirm extent. Aspirin and STEMI activation are
contraindicated; nitroglycerin alone may worsen dissection propagation (NSG 233 vascular emergencies).
Q11: A client has just had an ICD implanted. Which statement by the client indicates the need for further
teaching?
A. I will avoid leaning over running engines or arc welding equipment.
B. I will carry my ICD identification card with me at all times.
C. If I receive a shock, I should call 911 only if I receive more than one shock.
D. I can resume playing competitive contact sports in 2 weeks. *[CORRECT]*
Correct Answer: D
Rationale: Contact sports risk damaging the ICD generator and leads; the client should avoid them indefinitely. Other statements
reflect correct understanding (NSG 233 cardiac devices; QSEN Patient-Centered Care).
Q12: Which laboratory value requires the nurse to withhold warfarin and notify the provider?
A. INR 2.5
B. INR 1.8
C. INR 4.8 *[CORRECT]*
D. PT 25 seconds (control 11-13 sec)
Correct Answer: C
Rationale: An INR > 4.5 in a client on warfarin significantly increases bleeding risk; the nurse should hold the dose and notify
the provider (NSG 233 anticoagulation module). INR 2.5 is therapeutic for atrial fibrillation; INR 1.8 requires dosage increase;
PT alone is not used to manage warfarin therapy.
Q13: A client with chronic stable angina is prescribed ranolazine. The nurse understands this medication:
A. Decreases heart rate and blood pressure through beta-blockade.
B. Relaxes vascular smooth muscle through nitric oxide release.
C. Reduces myocardial oxygen demand by inhibiting late sodium current. *[CORRECT]*
D. Prevents platelet aggregation by blocking glycoprotein IIb/IIIa receptors.
Correct Answer: C
Rationale: Ranolazine is a late sodium current inhibitor that reduces myocardial wall stress and oxygen demand without
affecting hemodynamics (HR/BP), making it an add-on for refractory angina (NSG 233 cardiovascular pharmacology module).
