Question 64: A nurse is monitoring a patient post-carotid artery stenting. Which vital sign trend in the first 24 hours most warrants immediate notification of the physician?

Temperature of 37.4°C
Blood pressure rising from 130/80 to 165/95 mmHg (Correct answer)
Respiratory rate of 16 breaths/min
Heart rate of 68 bpm

Correct answer: Blood pressure rising from 130/80 to 165/95 mmHg

Hypertension after carotid stenting increases the risk of hyperperfusion syndrome, intracranial hemorrhage, and restenosis and must be promptly managed.

Question 65: Which waveform abnormality on the venous waveform (CVP tracing) is characteristic of cardiac tamponade?

Isolated elevation of the a wave without changes to x or y descents
Absence or blunting of the y descent with equalization of diastolic pressures across all cardiac chambers (Correct answer)
Normal waveform morphology with only elevated mean pressure
Prominent y descent with steep pressure drops

Correct answer: Absence or blunting of the y descent with equalization of diastolic pressures across all cardiac chambers

Tamponade impairs ventricular filling throughout diastole; the y descent (tricuspid opening) is blunted because pericardial pressure prevents ventricular expansion after tricuspid valve opening.

Question 66: Which cybersecurity practice is most important when a cardiovascular nurse accesses a patient's pacemaker interrogation report on a shared workstation?

Printing the report and leaving it at the nurses' station
Saving the report to the desktop for quick access

Switch permanently to a direct oral anticoagulant
Continue warfarin at the current dose
Hold warfarin and bridge with therapeutic low-molecular-weight heparin (Correct answer)
Hold warfarin and proceed without bridging

Correct answer: Hold warfarin and bridge with therapeutic low-molecular-weight heparin

Patients with mechanical heart valves have high thromboembolic risk and require therapeutic LMWH bridging when warfarin is interrupted for procedures.

Question 71: A cardiac nurse uses a clinical decision support (CDS) tool integrated in the EHR that flags a patient's estimated glomerular filtration rate (eGFR) of 28 mL/min before administering contrast for a cardiac CT. What is the priority nursing response?

Ignore the alert if the patient has no history of kidney disease
Administer a reduced contrast dose without notifying the provider
Notify the ordering provider and hold contrast pending nephrology or physician review (Correct answer)
Administer contrast as scheduled since the CDS alert is optional

Correct answer: Notify the ordering provider and hold contrast pending nephrology or physician review

An eGFR of 28 mL/min represents significant renal impairment and a high risk for contrast-induced nephropathy; the provider must be notified and contrast held pending review.

Question 72: How do Cardiac Vascular Nursing Exam professionals maintain digital competency?

Through ongoing training, practice with new tools, and staying current with technological advances (Correct answer)

Using the Just Culture model, what is the most appropriate response if the error resulted from a poorly designed medication ordering system?

Perform a system-level analysis and redesign the flawed process (Correct answer)
Discipline the nurse who administered the dose
Issue a mandatory competency re-evaluation for all nursing staff
Report the nurse to the state licensing board

Correct answer: Perform a system-level analysis and redesign the flawed process

Just Culture distinguishes human error from system failures; a poorly designed system warrants process redesign rather than individual punishment.

Question 76: 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?

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

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 80: In cardiogenic shock, which pathophysiological cascade leads to multiorgan failure?

Severely reduced cardiac output causes hypoperfusion, triggering inflammatory mediators and progressive organ dysfunction (Correct answer)
Coagulopathy initiates organ failure before hemodynamic compromise
Hypovolemia alone drives the organ failure cascade
Neurogenic vasodilation reduces perfusion pressure independently of cardiac output

Correct answer: Severely reduced cardiac output causes hypoperfusion, triggering inflammatory mediators and progressive organ dysfunction

Cardiogenic shock's primary low output state triggers sympathetic activation, systemic inflammation, and a downward spiral where ischemic organs release mediators that further depress cardiac function.

Question 81: Which cardiac biomarker pattern is most consistent with an acute MI that occurred approximately 24-48 hours before the laboratory draw?

Normal troponin I with significantly elevated myoglobin only
Troponin I already returned to normal with isolated CK-MB elevation
Mildly elevated troponin with markedly elevated BNP as the dominant finding
Elevated troponin I with near-peak CK-MB that is beginning to decline (Correct answer)

Correct answer: Elevated troponin I with near-peak CK-MB that is beginning to decline

Troponin I remains elevated for 7–14 days after MI, while CK-MB peaks at 24 hours and returns to normal by 48–72 hours; at 24–48 hours both remain elevated but CK-MB is declining.

Question 82: Why is evidence-based practice important in Cardiac Vascular Nursing Exam?

Phosphodiesterase inhibition increasing cyclic AMP in cardiac cells
Beta-1 receptor blockade reducing heart rate and contractility
Inhibition of late sodium current reduces calcium overload in ischemic cardiomyocytes without affecting heart rate or blood pressure (Correct answer)

Correct answer: Inhibition of late sodium current reduces calcium overload in ischemic cardiomyocytes without affecting heart rate or blood pressure

Ranolazine blocks the late inward sodium current that causes calcium overload in ischemic cells, improving diastolic function and reducing angina without hemodynamic effects on heart rate or blood pressure.

Question 84: A cardiac unit uses statistical process control (SPC) charts to monitor post-operative atrial fibrillation rates. A nurse sees seven consecutive data points below the mean. What does this pattern indicate?

Measurement error in data collection
Random variation within normal limits
An acceptable performance trend
A special cause requiring investigation (Correct answer)

Correct answer: A special cause requiring investigation

Seven consecutive points on one side of the mean is a Western Electric rule violation indicating a non-random special cause signal requiring investigation.

Question 85: In peripheral arterial disease (PAD), which pathophysiological change causes claudication pain?

Inflammatory myopathy unrelated to vascular supply
Inadequate arterial blood flow creating ischemia in exercising muscles (Correct answer)
Venous hypertension causing tissue edema and nerve compression
Arterial embolism causing sudden complete occlusion

Correct answer: Inadequate arterial blood flow creating ischemia in exercising muscles

Atherosclerotic stenosis limits blood flow to limb muscles during exercise; when oxygen demand exceeds supply, ischemia causes cramping pain that resolves with rest.

Question 86: What is the primary competency framework for Cardiac Vascular Nursing Exam professionals?

Self-assessed capabilities only
Structured competency standards defined by the certifying body (Correct answer)
Employer-specific requirements only
Ad-hoc skill development

Mild shortness of breath that is expected with exertion
Sustained ventricular tachycardia or ST elevation in leads without pathological Q waves (Correct answer)
Systolic blood pressure rise to 190 mmHg with normal symptoms

Correct answer: Sustained ventricular tachycardia or ST elevation in leads without pathological Q waves

Sustained VT or ST elevation in leads without prior Q waves indicates severe ischemia or arrhythmia warranting immediate cessation to prevent hemodynamic collapse or ventricular fibrillation.

Question 88: Chronic hypoxia in obstructive sleep apnea contributes to cardiovascular disease through which primary mechanism?

Hypoxia causes polycythemia that mechanically obstructs coronary arteries
Intermittent hypoxia exclusively affects pulmonary vasculature without systemic effects
Repetitive hypoxia activates the sympathetic nervous system and promotes endothelial dysfunction, hypertension, and atherosclerosis (Correct answer)
Sleep apnea causes direct myocardial fibrosis during hypoxic episodes

Correct answer: Repetitive hypoxia activates the sympathetic nervous system and promotes endothelial dysfunction, hypertension, and atherosclerosis

Each apneic episode triggers sympathetic surges, inflammatory responses, and oxidative stress that chronically elevate blood pressure, impair endothelial function, and accelerate atherosclerosis.

Question 89: Which finding on an ankle-brachial index (ABI) test is diagnostic of significant peripheral arterial disease?

ABI greater than 1.4 with non-compressible vessels
ABI of 1.0 to 1.3
ABI of 0.91 to 1.0 indicating borderline normal
ABI less than 0.90 (Correct answer)

Question 99: 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
Chronic hypertension promotes atherosclerosis causing embolic stroke and weakens small vessel walls causing rupture (Correct answer)
Hypertension reduces clotting factors, predisposing to bleeding only

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 100: During interdisciplinary rounds on a cardiac unit, the bedside nurse disagrees with the cardiologist's plan to discharge a patient she believes is hemodynamically unstable. What is the most appropriate first action?

Contact hospital administration to override the physician
Respectfully voice concerns using SBAR and request a reassessment before discharge orders are written (Correct answer)
Follow the physician's orders without comment to avoid conflict
Document disagreement in the chart and proceed with discharge

Correct answer: Respectfully voice concerns using SBAR and request a reassessment before discharge orders are written

SBAR provides a structured, assertive framework for nurses to communicate safety concerns to physicians during interdisciplinary discussions.

Question 101: Which statement BEST describes the teach-back method when educating cardiac patients?

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

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.

Left ventricular end-diastolic volume greater than 150 mL
Left ventricular ejection fraction (LVEF) less than 40% diagnoses HFrEF (Correct answer)
Tricuspid annular plane systolic excursion (TAPSE) less than 17mm

Correct answer: Left ventricular ejection fraction (LVEF) less than 40% diagnoses HFrEF

LVEF <40% defines HFrEF and triggers guideline-directed medical therapy with beta-blockers, ACE inhibitors/ARBs, and aldosterone antagonists that have proven mortality benefit.

Question 104: A nurse overhears a physician speaking loudly and dismissively to a patient with peripheral vascular disease who asked about alternative treatments. What is the nurse's most appropriate response?

Intervene calmly in the moment to support the patient, then speak privately with the physician about communication standards and report the behavior if it recurs (Correct answer)
Immediately file a formal complaint without speaking to the physician first
Do nothing to avoid conflict with the physician
Tell the patient to ignore the physician's tone and focus on the treatment plan

Correct answer: Intervene calmly in the moment to support the patient, then speak privately with the physician about communication standards and report the behavior if it recurs

Nurses are patient advocates and must address disrespectful provider-patient communication by supporting the patient and addressing the behavior through appropriate channels.

Question 105: A cardiovascular nurse is completing a quality audit and finds that heparin drip titration was performed outside the approved protocol by an RN. This finding should be classified as:

An acceptable nursing judgment that requires no action
A variance or protocol deviation requiring documentation and process review (Correct answer)

Double-blind randomized controlled trial
Case-control study matching for nurse experience level
Cross-sectional prevalence survey
Failure mode and effects analysis (FMEA) combined with process mapping (Correct answer)

Correct answer: Failure mode and effects analysis (FMEA) combined with process mapping

FMEA proactively identifies potential failure points and their effects before they occur, and when combined with process mapping after an RCA, it provides a comprehensive basis for prevention strategies.

Question 115: During a nuclear stress test, which finding indicates a fixed perfusion defect rather than ischemia?

Uniform tracer uptake in all myocardial segments on both images
Increased tracer uptake in the right ventricle on stress images only
A defect seen on stress imaging that fills in on rest imaging indicates fixed scar tissue
A perfusion defect present on both stress and rest images that does not change indicates prior infarction (scar) (Correct answer)

Correct answer: A perfusion defect present on both stress and rest images that does not change indicates prior infarction (scar)

A fixed defect (unchanged between stress and rest images) represents non-viable scar tissue from prior MI; a reversible defect (defect on stress, normal at rest) represents inducible ischemia.

Question 116: A nurse accesses a patient's digital care plan via the hospital's mobile application on a personal smartphone. Which security measure is most critical to protect patient data on this device?

Using the hospital Wi-Fi only when charting
Enabling remote wipe capability and using a strong PIN or biometric lock on the device (Correct answer)
Keeping the mobile app open for faster access between tasks
Storing patient information in a personal note-taking app for convenience

Correct answer: Enabling remote wipe capability and using a strong PIN or biometric lock on the device

Remote wipe capability combined with biometric or PIN authentication ensures that PHI can be secured or erased if the personal device is lost or stolen.

Correct answer: Systematic review with meta-analysis of RCTs

Systematic reviews with meta-analysis of multiple RCTs represent the highest level of evidence by synthesizing data across studies, reducing random error and bias.

Question 118: Which patient population requires MODIFIED cardiac education strategies due to specific physiological considerations?

Patients who work in healthcare
Middle-aged patients with no comorbidities
Elderly patients with cognitive impairment (Correct answer)
Young adult patients with congenital heart disease

Correct answer: Elderly patients with cognitive impairment

Elderly patients with cognitive impairment require simplified, repetitive teaching with caregiver involvement, shorter sessions, and reinforcement tools due to memory and processing limitations.

Question 119: Which finding on a 12-lead ECG in a patient with suspected right ventricular infarction requires the nurse to withhold nitroglycerin?

Left bundle branch block
T-wave inversions in leads V1–V3
ST elevation in leads II, III, and aVF with ST elevation in V4R (Correct answer)
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 120: A nurse is providing education to a patient with chronic venous insufficiency about compression therapy. Which instruction is MOST important?

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

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 121: A cardiac nurse uses a standardized handoff tool (e.g., SBAR) during shift change. This practice primarily supports which professional standard?

Safe communication and continuity of care (Correct answer)
Limiting information shared with the oncoming nurse
Efficiency by reducing handoff duration to under one minute
Eliminating the need for written nursing documentation

Correct answer: Safe communication and continuity of care

Standardized handoff tools like SBAR promote safe, structured communication to ensure accurate transfer of critical patient information between providers.

Question 122: When discussing secondary prevention after a myocardial infarction, the nurse should EMPHASIZE which medication class as cornerstone therapy that patients should NEVER stop without physician guidance?

Calcium channel blockers
Beta-blockers (Correct answer)
Nitrates
Loop diuretics

Correct answer: Beta-blockers

Beta-blockers are a cornerstone of post-MI therapy that reduce mortality by decreasing myocardial oxygen demand; abrupt discontinuation can cause rebound tachycardia and ischemia.

Question 123: When implementing evidence-based anticoagulation guidelines, a nurse notices a conflict between two high-quality systematic reviews. What is the BEST next step?

Choose the review with the larger sample size
Consult an interdisciplinary team and examine guideline methodology differences (Correct answer)
Default to physician preference until evidence is settled
Follow the older, more established guideline

Correct answer: Consult an interdisciplinary team and examine guideline methodology differences

When evidence conflicts, convening an interdisciplinary team and examining methodological differences between reviews allows for the most informed, patient-centered decision.

Question 124: Under CMS hospital discharge planning requirements, cardiovascular nurses must ensure that which element is completed before a patient is discharged following a cardiac procedure?

A signed waiver releasing the hospital from liability for complications
Confirmation that the patient has private insurance for follow-up care
Verification that the patient lives within 30 miles of the hospital
Assessment of post-discharge needs and a documented discharge plan communicated to the patient (Correct answer)

Correct answer: Assessment of post-discharge needs and a documented discharge plan communicated to the patient

CMS requires hospitals to assess each patient's discharge needs and provide a documented discharge plan, including education and referrals, before the patient leaves.

Question 125: A patient with atrial fibrillation expresses fear about taking anticoagulants. What is the nurse's BEST initial response?

Provide written materials about anticoagulants for the patient to read at home
Explain that the physician has ordered the medication and it must be taken
Acknowledge the patient's concerns and explore their specific fears before providing information (Correct answer)
Reassure the patient that side effects are rare and proceed with education

Correct answer: Acknowledge the patient's concerns and explore their specific fears before providing information

Acknowledging concerns and exploring specific fears first establishes therapeutic rapport and identifies targeted education needs, improving adherence.

Question 126: A hospital implements a digital early warning system (EWS) that automatically calculates a Modified Early Warning Score (MEWS). Which cardiovascular parameter contributes most to triggering a high MEWS alert?

Heart rate and systolic blood pressure deviations from baseline (Correct answer)
Blood type
Patient's reported pain score
Serum cholesterol level

Correct answer: Heart rate and systolic blood pressure deviations from baseline

Heart rate and systolic blood pressure are key vital sign components of MEWS calculations that, when significantly deranged, trigger escalation alerts for deteriorating cardiac patients.

Question 127: A cardiovascular nurse manager wants to assess whether a newly implemented pre-procedure checklist has reduced procedure cancellation rates. Which study design is most appropriate for this quality improvement evaluation?

Systematic review
Interrupted time series analysis (Correct answer)
Randomized controlled trial
Case-control study

Correct answer: Interrupted time series analysis

An interrupted time series analysis compares outcome trends before and after an intervention, making it well-suited for evaluating QI initiatives in clinical settings.

Question 128: A 68-year-old female on dual antiplatelet therapy (aspirin + clopidogrel) after drug-eluting stent placement 4 months ago now needs urgent hip replacement surgery. What is the safest approach?

Switch to warfarin bridging and stop both agents
Continue aspirin, stop clopidogrel 5 days before surgery after cardiology consultation (Correct answer)
Stop both antiplatelet agents 7 days preoperatively
Continue both antiplatelet agents through surgery

Correct answer: Continue aspirin, stop clopidogrel 5 days before surgery after cardiology consultation

Stopping dual antiplatelet therapy less than 6 months after DES placement carries a high risk of stent thrombosis; aspirin should be continued and clopidogrel stopped only after cardiology consultation confirms acceptable risk.

Question 129: What is a risk mitigation strategy in Cardiac Vascular Nursing Exam practice?

Only addressing risks after they occur
Ignoring low-probability risks
Implementing controls that reduce the likelihood or impact of identified risks (Correct answer)
Transferring all responsibility

Correct answer: Implementing controls that reduce the likelihood or impact of identified risks

This is fundamental to Cardiac Vascular Nursing Exam practice. Implementing controls that reduce the likelihood or impact of identified risks represents the professional standard for risk management in the Cardiac Vascular Nursing Exam certification framework.

Question 130: How should Cardiac Vascular Nursing Exam professionals prioritize identified risks?

Alphabetically
Randomly
Based on likelihood of occurrence combined with severity of potential impact (Correct answer)
By cost to mitigate only

Correct answer: Based on likelihood of occurrence combined with severity of potential impact

This is fundamental to Cardiac Vascular Nursing Exam practice. Based on likelihood of occurrence combined with severity of potential impact represents the professional standard for risk management in the Cardiac Vascular Nursing Exam certification framework.

Question 131: A cardiovascular nurse is participating in a Lean process improvement project on the cardiac unit. Which Lean concept focuses on eliminating steps in a process that do not add value from the patient's perspective?

Benchmarking
Waste reduction (Muda) (Correct answer)
Rapid cycle testing
Six Sigma

Correct answer: Waste reduction (Muda)

Muda is the Lean term for waste—any activity that consumes resources without adding value as perceived by the patient or customer.

Question 132: Which ankle-brachle index (ABI) value indicates severe peripheral arterial disease requiring urgent vascular evaluation?

0.41–0.70
Less than 0.40 (Correct answer)
0.71–0.90
0.91–1.00

Correct answer: Less than 0.40

An ABI less than 0.40 indicates severe PAD with critical limb ischemia, requiring urgent vascular surgery consultation.

Question 133: When appraising a study on antiplatelet therapy duration after drug-eluting stent placement, a nurse finds an I² statistic of 75%. What does this indicate about the meta-analysis?

75% of study results favor the intervention
Statistical power is adequate at 75%
The meta-analysis included 75 studies
High heterogeneity exists across the included studies (Correct answer)

Correct answer: High heterogeneity exists across the included studies

An I² of 75% indicates high statistical heterogeneity, meaning there is substantial variability in study results that is not attributable to chance alone.

Question 134: The nurse is teaching a post-myocardial infarction patient about resuming sexual activity. Which guideline is MOST accurate?

Sexual activity should be avoided for at least 6 months
Sexual activity is safe immediately after hospital discharge
Patients must complete a full cardiac rehabilitation program before resuming sexual activity
Most patients can resume sexual activity when they can climb two flights of stairs without symptoms (Correct answer)

Correct answer: Most patients can resume sexual activity when they can climb two flights of stairs without symptoms

The ability to climb two flights of stairs (equivalent to approximately 3-5 METs) without symptoms is a commonly used clinical guideline indicating readiness to resume sexual activity after MI.

Question 135: A vascular nurse observes an unlicensed assistive personnel (UAP) independently performing a post-procedural pedal pulse assessment on a patient after femoral artery access. The correct response is to:

Delegate future assessments to the UAP to manage nursing workload
Document the incident only if the patient complains
Intervene and clarify that vascular assessments after arterial procedures are within the RN scope of practice (Correct answer)
Allow it since UAPs can perform all bedside assessments

Correct answer: Intervene and clarify that vascular assessments after arterial procedures are within the RN scope of practice

Post-procedural vascular assessments require clinical judgment and fall within the RN scope of practice; they cannot be delegated to UAPs under the Nurse Practice Act.

Question 136: When communicating a critical lab value (e.g., potassium of 2.8 mEq/L) for a cardiac patient to a physician, which documentation practice is required after the verbal report?

Document only that the physician was called
Wait for a written order before documenting the communication
File the lab report in the chart without a separate nursing note
Document the time, value reported, name of provider notified, orders received, and read-back confirmation (Correct answer)

Correct answer: Document the time, value reported, name of provider notified, orders received, and read-back confirmation

Complete documentation of critical value communication — including read-back, time, and provider name — creates a clear safety record and meets Joint Commission standards.

Question 137: A nurse prepares to administer IV alteplase (tPA) for acute ischemic stroke. Which cardiac history represents an absolute contraindication?

Any prior intracranial hemorrhage (Correct answer)
Prior coronary artery bypass graft (CABG) more than 3 months ago
Remote history of stable angina
Controlled hypertension on antihypertensive medications

Correct answer: Any prior intracranial hemorrhage

Prior intracranial hemorrhage is an absolute contraindication to tPA because the fibrinolytic activity dramatically increases risk of re-bleeding into the previous hemorrhage site.

Question 138: A patient with a newly implanted pacemaker needs discharge education. Which activity restriction should the nurse include?

Avoid driving a car for 12 months
Avoid all air travel for 6 months
Refrain from lifting the arm on the implant side above the shoulder for 4–6 weeks (Correct answer)
Do not use a microwave oven within 10 feet

Correct answer: Refrain from lifting the arm on the implant side above the shoulder for 4–6 weeks

Patients with new pacemakers should avoid lifting the ipsilateral arm above shoulder level for 4–6 weeks to prevent lead dislodgement while the leads are stabilizing.

Question 139: A patient with coronary artery disease (CAD) asks about the DASH diet. Which statement by the nurse is MOST accurate?

The DASH diet is specifically designed for diabetics and may not help cardiac patients
The DASH diet requires eliminating all fats from the diet
The DASH diet emphasizes fruits, vegetables, whole grains, and low-fat dairy while limiting saturated fats and sodium (Correct answer)
The DASH diet is a high-protein plan that restricts carbohydrates

Correct answer: The DASH diet emphasizes fruits, vegetables, whole grains, and low-fat dairy while limiting saturated fats and sodium

The DASH (Dietary Approaches to Stop Hypertension) diet emphasizes fruits, vegetables, whole grains, and low-fat dairy while limiting saturated fats, sodium, and added sugars, benefiting both hypertension and CAD.

Question 140: A patient receiving IV vasopressin for vasodilatory shock develops chest pain. The nurse suspects which complication related to vasopressin's mechanism?

Vasopressin-induced pulmonary edema
Aortic dissection from acute hypertension
Allergic reaction to the synthetic peptide
Coronary vasoconstriction causing myocardial ischemia (Correct answer)

Correct answer: Coronary vasoconstriction causing myocardial ischemia

Vasopressin (V1 receptor agonist) causes non-selective vasoconstriction including coronary arteries, potentially reducing myocardial perfusion and causing ischemia, especially in patients with CAD.

Question 141: A sentinel event involving a cardiac patient who received a potassium infusion at 10 times the ordered rate is being reviewed. Which process is most appropriate for this level of serious adverse event?

PDSA cycle
Peer review committee
Root cause analysis (RCA) (Correct answer)
Occurrence variance report only

Correct answer: Root cause analysis (RCA)

A root cause analysis (RCA) is the required structured process for investigating sentinel events to identify contributing factors and prevent recurrence.

Question 142: A patient on amiodarone for atrial fibrillation also takes warfarin. The nurse anticipates which drug interaction?

Amiodarone inhibits warfarin metabolism, increasing INR and bleeding risk (Correct answer)
Amiodarone increases warfarin metabolism, decreasing anticoagulant effect
No significant interaction exists between amiodarone and warfarin
Amiodarone displaces warfarin from protein binding, reducing its effectiveness

Correct answer: Amiodarone inhibits warfarin metabolism, increasing INR and bleeding risk

Amiodarone inhibits CYP2C9, the primary enzyme metabolizing warfarin's S-enantiomer, causing warfarin accumulation and significantly elevated INR requiring dose reduction.

Question 143: A vascular nurse discovers that a colleague documented a peripheral vascular assessment that was never actually performed. The most appropriate initial action is to:

Ask the colleague to backdate a corrected entry
Ignore it since the patient was not harmed
Report the falsification to the charge nurse or supervisor (Correct answer)
Correct the chart without notifying anyone

Correct answer: Report the falsification to the charge nurse or supervisor

Falsification of medical records is a serious breach of professional and legal standards that must be reported through proper channels.

Question 144: Which mechanism causes the widened pulse pressure seen in aortic regurgitation?

Increased systemic vascular resistance raises both systolic and diastolic pressure
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

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 145: A cardiovascular unit tracks its central line-associated bloodstream infection (CLABSI) rate. After implementing a CLABSI bundle, the rate drops from 3.2 to 0.8 per 1,000 line-days. Which statement best describes this outcome?

The rate should be compared to a national benchmark before drawing conclusions
The result is clinically significant only if statistically significant
Control charts must confirm the change before action is warranted
A 75% reduction suggests the bundle is highly effective and should be sustained (Correct answer)

Correct answer: A 75% reduction suggests the bundle is highly effective and should be sustained

A 75% reduction in CLABSI rate is a clinically meaningful improvement; sustaining the bundle while continuing to monitor is appropriate.

Question 146: Which feature of a cardiac implantable electronic device (CIED) remote monitoring platform most directly reduces unplanned hospital readmissions?

Color-coded patient risk stratification dashboards
Automatic scheduling of in-person device checks
Automatic device recharging
Early detection of fluid accumulation through impedance trending (Correct answer)

Correct answer: Early detection of fluid accumulation through impedance trending

Intrathoracic impedance monitoring detects early fluid accumulation in heart failure patients, allowing intervention before symptoms necessitate hospitalization.

Question 147: Which interaction between statins and which specific drug class requires monitoring for myopathy?

Statins plus beta-blockers increase muscle breakdown risk
Statins combined with ACE inhibitors cause myopathy
Concurrent use of statins with fibrates (especially gemfibrozil) significantly increases risk of rhabdomyolysis (Correct answer)
Statins and diuretics together cause skeletal muscle toxicity

Correct answer: Concurrent use of statins with fibrates (especially gemfibrozil) significantly increases risk of rhabdomyolysis

Gemfibrozil inhibits statin glucuronidation, dramatically increasing statin plasma levels, which raises the risk of statin-induced myopathy and potentially fatal rhabdomyolysis.

Question 148: Snap Opening

Goal door to ECG time
Aortic Stenosis
Mitral stenosis (Correct answer)
Mitral regurgitation

Correct answer: Mitral stenosis

An 'opening snap' is a distinct, high-pitched sound heard early in diastole, which is a classic auscultatory finding in patients with mitral stenosis. It occurs when the stenotic mitral valve, if still pliable, opens abruptly due to increased left atrial pressure.

Question 149: A patient with an implanted cardioverter-defibrillator (ICD) asks when they should seek medical attention. Which patient statement indicates correct understanding?

I will call my cardiologist if my ICD fires even once (Correct answer)
I only need to worry if I feel nothing when the ICD fires
I will go to the ER if my ICD fires more than three times in one day
I should expect my ICD to fire weekly as normal function

Correct answer: I will call my cardiologist if my ICD fires even once

Any ICD discharge warrants prompt notification of the cardiologist to determine the cause, assess arrhythmia recurrence, and evaluate device function.

Question 150: When teaching a patient about recognizing signs of deep vein thrombosis (DVT), which symptom should the nurse emphasize as the MOST classic presentation?

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

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 151: Which patient assessment finding contraindicates the use of IV adenosine for SVT termination?

Controlled hypertension
Mild renal insufficiency (GFR 45 mL/min)
Severe reactive airway disease or asthma (Correct answer)
First-degree atrioventricular block

Correct answer: Severe reactive airway disease or asthma

Adenosine can trigger severe bronchospasm in asthmatic patients because adenosine receptors in bronchial smooth muscle mediate bronchoconstriction, making it contraindicated in reactive airway disease.
