A plan to convince the patient to reconsider at the next assessment
The nurse's opinion about why the patient made the wrong decision
Only that the patient refused and signed the AMA form
The patient's stated reason for refusal, the risks explained to the patient, confirmation that the patient demonstrated decision-making capacity, and the provider notified (Correct answer)

Correct answer: The patient's stated reason for refusal, the risks explained to the patient, confirmation that the patient demonstrated decision-making capacity, and the provider notified

Informed refusal documentation must capture the patient's reasoning, risks communicated, capacity assessment, and provider notification to create a legally and ethically complete record.

Question 126: A patient with heart failure is being taught to use a symptom diary. Which instruction regarding when to call the healthcare provider is MOST important?

Call if you gain more than 5 pounds in one month
Call if you gain more than 2 pounds in one day or 5 pounds in one week (Correct answer)
Call if you notice your urine is darker than usual
Call only if shortness of breath prevents you from sleeping

Correct answer: Call if you gain more than 2 pounds in one day or 5 pounds in one week

A weight gain of more than 2 pounds in 24 hours or 5 pounds in one week indicates rapid fluid retention in heart failure requiring prompt medical evaluation.

Question 127: When teaching a patient about recognizing signs of deep vein thrombosis (DVT), which symptom should the nurse emphasize as the MOST classic presentation?

Intermittent claudication with exertion
Bilateral leg pain worse at night
Numbness and tingling in both feet
Unilateral calf pain, swelling, and warmth (Correct answer)

Correct answer: Unilateral calf pain, swelling, and warmth

Classic DVT presentation includes unilateral calf pain, swelling, warmth, and erythema, which patients must recognize to seek immediate care.

Question 128: Which mechanism causes the widened pulse pressure seen in aortic regurgitation?

Decreased heart rate with increased stroke volume raising systolic pressure only
High stroke volume increases systolic pressure while regurgitant backflow lowers diastolic pressure (Correct answer)
Left ventricular hypertrophy increasing contractility without valvular effect
Increased systemic vascular resistance raises both systolic and diastolic pressure

Correct answer: High stroke volume increases systolic pressure while regurgitant backflow lowers diastolic pressure

In aortic regurgitation, large forward stroke volume raises systolic pressure, while regurgitation of blood back into the ventricle during diastole causes low diastolic pressure.

Question 129: Which pathophysiological change makes a thin-cap fibroatheroma (TCFA) a vulnerable plaque prone to rupture?

Thick calcified cap with minimal lipid content
Dense smooth muscle cell population stabilizing the plaque structure
Complete absence of neovascularization within the plaque
Thin fibrous cap over a large lipid-rich necrotic core with abundant macrophage infiltration (Correct answer)

Correct answer: Thin fibrous cap over a large lipid-rich necrotic core with abundant macrophage infiltration

TCFA has a large, soft lipid core covered by a thin fibrous cap that is weakened by macrophage-secreted matrix metalloproteinases, making it prone to rupture and acute thrombosis.

Question 130: Which finding on a 12-lead ECG in a patient with suspected right ventricular infarction requires the nurse to withhold nitroglycerin?

ST elevation in leads II, III, and aVF with ST elevation in V4R (Correct answer)
Left bundle branch block
T-wave inversions in leads V1–V3
ST depression in leads V1–V4

Correct answer: ST elevation in leads II, III, and aVF with ST elevation in V4R

Right ventricular infarction (evidenced by inferior ST elevation plus V4R elevation) causes preload-dependent hemodynamics; nitroglycerin causes vasodilation that can precipitate severe hypotension.

Question 131: A patient in the cardiac ICU has a mean arterial pressure (MAP) of 58 mmHg after cardiac surgery. Which intervention should the nurse anticipate first?

Begin immediate chest compressions
Infuse IV fluid bolus and reassess, then consider vasopressors if no response (Correct answer)
Apply a nitroglycerin patch
Administer oral metoprolol

Correct answer: Infuse IV fluid bolus and reassess, then consider vasopressors if no response

A MAP below 65 mmHg requires prompt intervention; initial fluid resuscitation followed by vasopressors if unresponsive maintains organ perfusion in post-surgical hypotension.

Question 132: Suppose a patient experiences an increased heart rate after receiving nitroglycerin for angina. The following is the root issue:

Myocardial infarction
Increased cardiac ischemia
Atrial fibrillation
Reflex tachycardia (Correct answer)

Correct answer: Reflex tachycardia

Nitroglycerin is a potent vasodilator that reduces preload and afterload, thereby decreasing myocardial oxygen demand and relieving angina. However, this vasodilation can cause a drop in systemic blood pressure, which triggers the baroreceptor reflex. This reflex response leads to an increase in heart rate (tachycardia) as the body attempts to compensate for the decreased blood pressure, known as reflex tachycardia.

Question 133: A patient scheduled for a carotid endarterectomy has capacity and refuses a blood transfusion for religious reasons. The nurse's correct action is to:

Administer the transfusion if the surgeon orders it as life-saving
Override the refusal since the procedure is elective
Document the refusal, notify the surgeon, and ensure the refusal is reflected in the consent process (Correct answer)
Contact the hospital ethics committee to override the patient's decision

Correct answer: Document the refusal, notify the surgeon, and ensure the refusal is reflected in the consent process

A competent patient has the legal and ethical right to refuse treatment, including blood transfusions; the nurse must document this, notify the team, and respect the patient's autonomy.

Question 134: A nurse reviews a patient's continuous glucose monitoring (CGM) data integrated into the cardiac ICU's central monitoring system. Why is tight glycemic control particularly important for this population?

Hyperglycemia has no effect on cardiac outcomes
Glucose monitoring is only relevant for diabetic patients in the ICU
Hyperglycemia increases inflammation, impairs wound healing, and worsens outcomes post-cardiac surgery (Correct answer)
CGM is used primarily for insulin dosing convenience, not clinical outcomes

Correct answer: Hyperglycemia increases inflammation, impairs wound healing, and worsens outcomes post-cardiac surgery

Hyperglycemia in cardiac patients increases oxidative stress, promotes inflammation, and is independently associated with increased mortality and wound complications after cardiac surgery.

Question 135: A nurse is providing education to a patient with chronic venous insufficiency about compression therapy. Which instruction is MOST important?

Apply compression stockings after showering while legs are still moist
Apply compression stockings at bedtime after elevating legs for one hour
Wear compression stockings only when standing for prolonged periods
Apply compression stockings in the morning before getting out of bed (Correct answer)

Correct answer: Apply compression stockings in the morning before getting out of bed

Compression stockings should be applied in the morning before getting out of bed when venous pooling is minimal and edema has not yet formed.

Question 136: A patient's cardiac catheterization report shows 75% stenosis of the left anterior descending (LAD) artery. The nurse understands this supplies which myocardial territory?

Lateral wall and posterior left ventricle predominantly
Right ventricle and right atrium exclusively
Inferior wall of the left ventricle and posterior septum
Anterior left ventricular wall, interventricular septum, and apex (Correct answer)

Correct answer: Anterior left ventricular wall, interventricular septum, and apex

The LAD perfuses the anterior wall, anterior two-thirds of the interventricular septum, and the cardiac apex, making it critical to a large amount of left ventricular mass.

Question 137: A 65-year-old male in the cardiac step-down unit is on metoprolol and lisinopril post-MI. His HR is 48 bpm and BP is 96/60 mmHg with complaints of dizziness. His potassium is 5.8 mEq/L. What is the nurse's priority action?

Administer atropine 1 mg IV push
Increase IV fluid rate to improve perfusion pressure
Administer calcium gluconate IV for hyperkalemia
Hold metoprolol and notify the provider immediately (Correct answer)

Correct answer: Hold metoprolol and notify the provider immediately

Symptomatic bradycardia and hypotension in a patient on beta-blockers requires holding the offending medication and notifying the provider before further interventions.

Question 138: Which CMS rule requires that cardiac vascular patients be informed of their rights, including the right to participate in their care plan, prior to or at the time of admission?

Conditions of Participation: Patient Rights (42 CFR 482.13) (Correct answer)
HIPAA Minimum Necessary Rule
EMTALA On-Call Requirements
The Anti-Kickback Statute

Correct answer: Conditions of Participation: Patient Rights (42 CFR 482.13)

42 CFR 482.13 requires hospitals to inform patients of their rights at or before admission, including the right to make decisions about their care.

Question 139: A patient with end-stage heart failure on maximal medical therapy is evaluated for heart transplant. Which condition would be an absolute contraindication to cardiac transplantation?

Insulin-dependent diabetes with no end-organ damage
Age 65 years
History of atrial fibrillation
Fixed pulmonary hypertension with PVR > 6 Wood units (Correct answer)

Correct answer: Fixed pulmonary hypertension with PVR > 6 Wood units

Fixed (irreversible) pulmonary hypertension with PVR >6 Wood units is an absolute contraindication to cardiac transplantation because the donor right ventricle cannot overcome the elevated pulmonary resistance.

Question 140: Which mechanism explains why hypertensive patients are at increased risk for both ischemic stroke and hemorrhagic stroke?

Hypertension only affects large vessels, causing embolic events
Hypertension causes cerebral vasospasm as the only mechanism
Hypertension reduces clotting factors, predisposing to bleeding only
Chronic hypertension promotes atherosclerosis causing embolic stroke and weakens small vessel walls causing rupture (Correct answer)

Correct answer: Chronic hypertension promotes atherosclerosis causing embolic stroke and weakens small vessel walls causing rupture

Chronic hypertension accelerates atherosclerosis in large cerebral arteries predisposing to embolic stroke, while also causing lipohyalinosis and microaneurysm formation in small penetrating arteries predisposing to hemorrhage.

Question 141: A patient with peripheral artery disease (PAD) asks how to prevent progression. Which lifestyle modification should the nurse PRIORITIZE?

Smoking cessation (Correct answer)
Reducing alcohol consumption
Maintaining a food diary
Starting a low-impact swimming program

Correct answer: Smoking cessation

Smoking is the single most important modifiable risk factor for PAD, causing vasoconstriction and accelerating atherosclerosis; cessation is the highest priority intervention.

Question 142: A cardiovascular nurse researcher is designing a study on nurse-led hypertension clinics. Which study design BEST establishes causality between the intervention and blood pressure outcomes?

Retrospective chart review
Prospective randomized controlled trial (Correct answer)
Case-control study
Cross-sectional survey

Correct answer: Prospective randomized controlled trial

A prospective RCT with randomization and a control group is the gold-standard design for establishing causality between an intervention and outcomes.

Question 143: Which mechanism explains the development of dependent edema in right heart failure?

Elevated central venous pressure impairs venous return from peripheral tissues, increasing hydrostatic pressure in capillaries (Correct answer)
Renal sodium retention independent of venous hypertension
Lymphatic obstruction caused by right atrial enlargement
Reduced plasma oncotic pressure from cardiac-related malnutrition

Correct answer: Elevated central venous pressure impairs venous return from peripheral tissues, increasing hydrostatic pressure in capillaries

Right ventricular failure raises right atrial and systemic venous pressure, which increases capillary hydrostatic pressure in dependent areas, pushing fluid into interstitial tissue.

Question 144: A patient 48 hours post-MI develops a new holosystolic murmur at the apex with radiation to the axilla, dyspnea, and pulmonary edema. Echo shows flail mitral leaflet. What intervention is most likely needed?

Thrombolysis to restore coronary perfusion
Aggressive diuresis and nitrates only
Intra-aortic balloon pump as bridge to emergency mitral valve surgery (Correct answer)
Implantation of a permanent pacemaker

Correct answer: Intra-aortic balloon pump as bridge to emergency mitral valve surgery

Acute papillary muscle rupture causing severe mitral regurgitation post-MI is a surgical emergency; IABP reduces afterload and provides hemodynamic support as a bridge to surgery.

Question 145: A patient with chronic heart failure is admitted with decompensation. Which finding on risk stratification best predicts 30-day mortality and readmission?

Peripheral edema with weight gain of 3 lbs
New-onset atrial fibrillation during hospitalization
Elevated BNP >1000 pg/mL at discharge (Correct answer)
Systolic blood pressure of 110 mmHg on admission

Correct answer: Elevated BNP >1000 pg/mL at discharge

A discharge BNP greater than 1000 pg/mL is strongly associated with increased 30-day mortality and heart failure readmission rates.

Question 146: When reviewing a patient's telemetry strip, you note the QRS complexes are wide and bizarre with a rate of 180 bpm and no discernible P waves. Which digital monitoring alert should have fired first?

Bradycardia alert
Ventricular tachycardia alert (Correct answer)
ST-elevation alert
Atrial fibrillation alert

Correct answer: Ventricular tachycardia alert

Wide, bizarre QRS complexes at 180 bpm with absent P waves are characteristic of ventricular tachycardia, which modern telemetry systems are programmed to detect and alarm.

Question 147: How do continuing education requirements benefit Cardiac Vascular Nursing Exam certified professionals?

They ensure professionals stay current with evolving industry practices and knowledge (Correct answer)
They only benefit training providers
They are unnecessary formalities
They reduce practical skills

Correct answer: They ensure professionals stay current with evolving industry practices and knowledge

This is fundamental to Cardiac Vascular Nursing Exam practice. They ensure professionals stay current with evolving industry practices and knowledge represents the professional standard for professional standards in the Cardiac Vascular Nursing Exam certification framework.

Question 148: A cardiovascular unit implements a standardized handoff tool (I-PASS) for shift change. Six months later, the unit reports a 40% reduction in handoff-related adverse events. Which quality domain from the IOM's 'Crossing the Quality Chasm' framework does this improvement most directly address?

Effectiveness
Safety (Correct answer)
Timeliness
Efficiency

Correct answer: Safety

Reducing handoff-related adverse events directly addresses the IOM's Safety domain—preventing harm to patients from care processes.

Question 149: Which statement BEST describes the teach-back method when educating cardiac patients?

The nurse demonstrates a skill and the patient watches
The nurse repeats the same information multiple times
Written materials are provided and the patient signs a form
The patient is asked to explain information back in their own words (Correct answer)

Correct answer: The patient is asked to explain information back in their own words

The teach-back method involves asking patients to explain health information in their own words, confirming understanding and identifying gaps that need re-education.

Question 150: A patient with heart failure is being educated about daily self-monitoring. Which instruction is MOST important for early detection of fluid retention?

Weigh yourself every morning before eating (Correct answer)
Record urine output for 24 hours every week
Measure blood pressure twice daily
Check ankle circumference weekly

Correct answer: Weigh yourself every morning before eating

Daily morning weight measurement before eating and after urinating is the most sensitive early indicator of fluid retention in heart failure patients.

Question 151: A cardiac nurse is caring for a patient whose advance directive specifies 'no resuscitation,' but the patient's adult children are demanding that everything be done. What is the nurse's primary obligation?

Follow the family's wishes since they are the legal next of kin
Honor the patient's documented advance directive and work with the team and ethics committee to support the family through the decision (Correct answer)
Withhold the advance directive information from the family to avoid conflict
Attempt resuscitation to avoid family conflict and document the contradiction afterward

Correct answer: Honor the patient's documented advance directive and work with the team and ethics committee to support the family through the decision

A valid advance directive reflects the patient's autonomous decision and legally and ethically supersedes family requests; the care team must honor it while supporting the family.

Cardiac-Vascular Nursing Board Certification (CV-BC)

The CV-BC credential from the American Nurses Credentialing Center (ANCC) validates expert nursing knowledge and clinical competency in cardiovascular patient assessment, care planning, evaluation, and patient education across cardiac and vascular settings.
