Cardiology is one of the most intimidating sections of FNP board prep.

Not because every question is impossible.

But because cardiology feels huge.

Hypertension. Chest pain. Heart failure. EKGs. Atrial fibrillation. Peripheral artery disease. Murmurs. Lipids. Anticoagulation. Emergency referrals. Medication contraindications.

It can feel like you need to become a cardiologist just to pass your FNP boards.

You do not.

For the AANP and ANCC exams, cardiology questions usually test something much more practical:

Can you recognize the pattern? Can you identify the safest next step? Can you separate stable from unstable? Can you choose the right first-line treatment? Can you avoid the classic board trap?

That is the goal of this FNP cardiology board review.

We are going to break cardiology down into five high-yield topics every future Family Nurse Practitioner should understand before sitting for boards:

Hypertension
Heart failure
Coronary artery disease and acute coronary syndromes
Atrial fibrillation
Peripheral artery disease

These are not the only cardiology topics you need to study, but they are foundational. If you understand these five areas well, you will be much more prepared for board-style cardiology questions.

Let’s simplify the chaos.

1. Hypertension: Know the Diagnosis, Staging, and First-Line Treatment

Hypertension is one of the most common primary care conditions and one of the most commonly tested cardiology concepts on FNP boards.

The board does not usually ask complicated hypertension management questions. Instead, it wants to know whether you can:

Correctly diagnose hypertension
Stage the blood pressure reading
Recommend lifestyle modification
Choose an appropriate first-line medication
Recognize hypertensive urgency versus emergency
Know when comorbidities change your medication choice

The biggest mistake students make is treating one isolated high blood pressure reading like a diagnosis.

How Hypertension Is Diagnosed

A single elevated office reading is not enough to diagnose hypertension in a stable patient.

For board purposes, hypertension should be diagnosed based on repeated elevated blood pressure readings, ideally using accurate measurement technique and confirmation outside the office when appropriate.

Think:

Repeated elevated readings = diagnosis. One random high reading = recheck, confirm, and assess context.

Board questions may give you a patient who is anxious, in pain, rushing into the clinic, or drinking caffeine. Do not jump straight to diagnosing hypertension unless the stem gives you repeated elevated readings.

Blood Pressure Categories to Know

For FNP boards, you should know the basic blood pressure categories:

Normal: Systolic less than 120 and diastolic less than 80

Elevated: Systolic 120–129 and diastolic less than 80

Stage 1 Hypertension: Systolic 130–139 or diastolic 80–89

Stage 2 Hypertension: Systolic 140 or higher or diastolic 90 or higher

Severe Hypertension: Blood pressure greater than 180/120

The board may ask you to classify the blood pressure. Pay attention to the higher category. If either the systolic or diastolic number is in a higher stage, classify the patient based on the higher stage.

Example:

A blood pressure of 138/92 is not Stage 1 just because the systolic is 138. The diastolic is 92, so this is Stage 2 hypertension.

First-Line Hypertension Medications

For most uncomplicated adults with hypertension, first-line medication options include:

Thiazide or thiazide-like diuretics
ACE inhibitors
Angiotensin receptor blockers
Calcium channel blockers

The board loves medication safety.

So do not just memorize the drug classes. Know the patient-specific reason you would choose or avoid them.

High-Yield Medication Pearls

ACE inhibitors and ARBs Often preferred when hypertension occurs with diabetes, chronic kidney disease, or albuminuria. Monitor renal function and potassium. Do not use ACE inhibitors or ARBs in pregnancy. Do not combine an ACE inhibitor with an ARB.

Thiazide diuretics Common first-line option, especially in uncomplicated hypertension. Monitor electrolytes, especially sodium and potassium. They may increase uric acid, so be cautious in patients with gout.

Calcium channel blockers Useful first-line option. Dihydropyridines such as amlodipine can cause peripheral edema. Non-dihydropyridines such as diltiazem and verapamil affect heart rate and AV node conduction.

Lifestyle Modification Still Matters

Do not skip lifestyle modification on boards.

Lifestyle recommendations for hypertension commonly include:

Weight loss if overweight or obese
DASH-style eating pattern
Sodium reduction
Regular aerobic physical activity
Limiting alcohol intake
Smoking cessation
Home blood pressure monitoring
Stress reduction when appropriate

If the question asks for the best initial step in a low-risk patient with Stage 1 hypertension, lifestyle modification may be the answer.

If the patient has Stage 2 hypertension, diabetes, chronic kidney disease, known cardiovascular disease, or elevated cardiovascular risk, medication therapy becomes more likely.

Hypertensive Urgency vs. Emergency

This is a major board trap.

Hypertensive urgency: Severely elevated blood pressure without acute target organ damage.

Hypertensive emergency: Severely elevated blood pressure with acute target organ damage.

Target organ damage may include:

Chest pain or myocardial ischemia
Acute pulmonary edema
Neurologic deficits
Stroke symptoms
Encephalopathy
Acute kidney injury
Aortic dissection
Papilledema

The number matters, but the symptoms matter more.

A patient with blood pressure of 188/122 and no symptoms may be managed very differently than a patient with blood pressure of 180/110 and crushing chest pain, neurologic deficits, or acute shortness of breath.

FNP Board Trap

Do not diagnose hypertension from one elevated reading in a stable patient.

Do not send every patient with blood pressure over 180/120 to the emergency department automatically. First, assess for signs and symptoms of acute target organ damage.

The board is testing whether you know the difference between severe asymptomatic hypertension and hypertensive emergency.

Practice Question

A 52-year-old patient has blood pressure readings of 146/94 and 148/92 on two separate office visits. She has no chest pain, shortness of breath, neurologic symptoms, or evidence of acute target organ damage. Which classification is most appropriate?

A. Elevated blood pressure B. Stage 1 hypertension C. Stage 2 hypertension D. Hypertensive emergency

Answer: C. Stage 2 hypertension

Rationale: Stage 2 hypertension is defined as systolic blood pressure of 140 or higher or diastolic blood pressure of 90 or higher. She has repeated elevated readings in the Stage 2 range and no evidence of hypertensive emergency.

2. Heart Failure: Know HFrEF, HFpEF, Symptoms, and Medication Priorities

Heart failure can feel complicated, but FNP board questions usually focus on pattern recognition and broad treatment principles.

The exam wants to know if you can recognize heart failure symptoms, interpret ejection fraction, and understand the difference between systolic and diastolic dysfunction.

Classic Heart Failure Symptoms

Common symptoms and exam findings include:

Dyspnea on exertion
Orthopnea
Paroxysmal nocturnal dyspnea
Fatigue
Lower extremity edema
Weight gain from fluid retention
Crackles or rales
Jugular venous distention
S3 heart sound, especially in volume overload
Decreased exercise tolerance

If the question stem says the patient sleeps on multiple pillows, wakes up gasping for air, has bilateral leg swelling, and has crackles, think heart failure.

The Ejection Fraction Breakdown

For board purposes, know these categories:

HFrEF: Heart Failure with Reduced Ejection Fraction EF is 40% or less.

This is usually systolic dysfunction. The heart cannot pump effectively.

HFmrEF: Heart Failure with Mildly Reduced Ejection Fraction EF is 41–49%.

This is a middle category and may be less heavily tested, but you should recognize it.

HFpEF: Heart Failure with Preserved Ejection Fraction EF is 50% or higher.

This is usually diastolic dysfunction. The heart contracts normally but does not relax and fill properly.

HFrEF: The Medication Framework

For FNP boards, HFrEF is the heart failure category where guideline-directed medical therapy is most emphasized.

The major medication framework includes:

ARNI, ACE inhibitor, or ARB
Evidence-based beta-blocker
Mineralocorticoid receptor antagonist
SGLT2 inhibitor

Loop diuretics are also commonly used for symptom relief when the patient is volume overloaded, but they do not replace disease-modifying therapy.

High-Yield HFrEF Medication Pearls

Beta-blockers Use evidence-based options such as carvedilol, metoprolol succinate, or bisoprolol. Avoid starting or increasing beta-blockers in acute decompensated heart failure until the patient is stabilized.

ACE inhibitors, ARBs, and ARNIs Used to reduce afterload and improve outcomes. Monitor renal function, potassium, and blood pressure.

Mineralocorticoid receptor antagonists Examples include spironolactone and eplerenone. Monitor potassium and renal function.

SGLT2 inhibitors Now part of heart failure management, even beyond diabetes. Board questions may include these as part of updated heart failure therapy.

Loop diuretics Used for congestion and fluid overload. Think furosemide, bumetanide, or torsemide. Monitor electrolytes, renal function, weight, and volume status.

HFpEF: What the Board Wants

HFpEF is usually about managing comorbidities and symptoms.

Common priorities include:

Control hypertension
Manage diabetes
Treat volume overload with diuretics when needed
Address atrial fibrillation
Encourage lifestyle modification
Consider SGLT2 inhibitor therapy when appropriate
Evaluate for ischemia, valvular disease, sleep apnea, and other contributors

HFpEF is common in older adults and patients with hypertension, obesity, diabetes, and atrial fibrillation.

Diagnosis: What Test Confirms Heart Failure Type?

The best test to evaluate ejection fraction is an echocardiogram.

BNP or NT-proBNP can support the diagnosis, especially when dyspnea is present, but echo helps define the type of heart failure.

FNP Board Trap

Do not confuse heart failure symptoms with COPD or pneumonia without looking at the full picture.

Crackles, orthopnea, paroxysmal nocturnal dyspnea, edema, and elevated BNP point toward heart failure.

Also remember: if a patient with known heart failure suddenly worsens, assess for triggers such as medication nonadherence, high sodium intake, ischemia, infection, arrhythmia, renal dysfunction, or uncontrolled hypertension.

Practice Question

A 68-year-old patient presents with dyspnea on exertion, orthopnea, bilateral lower extremity edema, and crackles. Echocardiogram shows an ejection fraction of 35%. Which type of heart failure does this patient have?

A. HFpEF B. HFrEF C. Stable angina D. Peripheral artery disease

Answer: B. HFrEF

Rationale: An ejection fraction of 40% or less is consistent with heart failure with reduced ejection fraction. This is typically systolic dysfunction.

3. Coronary Artery Disease and ACS: Separate Stable Angina, Unstable Angina, NSTEMI, and STEMI

Chest pain questions are extremely important for FNP boards because they test safety.

The board wants to know whether you can recognize when a patient needs emergency care.

When you see chest pain, always ask:

Is this stable or unstable? Is this predictable or new/worsening? Are troponins elevated? Are there ST elevations? Does this patient need emergency referral?

Stable Angina

Stable angina is predictable.

It usually occurs with exertion or emotional stress and improves with rest or nitroglycerin.

Classic description:

Substernal chest pressure
Triggered by exertion
Relieved by rest
Relieved by nitroglycerin
Predictable pattern

Stable angina is concerning and needs evaluation, but it is not the same as acute coronary syndrome.

Unstable Angina

Unstable angina is a form of acute coronary syndrome.

Think unstable when chest pain is:

New onset
Occurring at rest
Increasing in frequency
Increasing in severity
Lasting longer than usual
Not relieved by rest or nitroglycerin

The key board distinction:

Unstable angina has no troponin elevation.

NSTEMI

NSTEMI stands for non-ST-elevation myocardial infarction.

The chest pain may look very similar to unstable angina, but the difference is myocardial injury.

Key findings:

Chest pain or ischemic symptoms
Elevated troponin
No ST-segment elevation

STEMI

STEMI is the emergency you cannot miss.

Key findings:

Chest pain or ischemic symptoms
Elevated troponin
ST-segment elevation on EKG

STEMI requires rapid reperfusion.

For board purposes: time matters. This patient needs emergency management, rapid EKG interpretation, antiplatelet therapy when appropriate, and urgent reperfusion planning.

Do Not Over-Rely on MONA

Many students memorize MONA or MONA BASH.

That can help you remember some therapies, but it is not the safest way to think through modern ACS questions.

Instead, think:

Is the patient unstable?
Get an EKG quickly.
Check troponins.
Give aspirin when not contraindicated.
Use nitroglycerin when appropriate and not contraindicated.
Give oxygen only if hypoxic or in respiratory distress.
Antiplatelet therapy, anticoagulation, statins, and invasive management depend on the clinical scenario.
STEMI requires rapid reperfusion.

Nitroglycerin Contraindications

Boards love nitroglycerin contraindications.

Avoid nitroglycerin in patients with:

Recent phosphodiesterase-5 inhibitor use
Severe hypotension
Suspected right ventricular infarction
Severe aortic stenosis, depending on the clinical context

If the question mentions sildenafil, tadalafil, vardenafil, or erectile dysfunction medication, pause before choosing nitroglycerin.

Atypical ACS Presentations

Do not expect every patient to present with dramatic crushing chest pain.

Older adults, women, and patients with diabetes may present with:

Shortness of breath
Nausea or vomiting
Epigastric discomfort
Jaw pain
Back pain
Fatigue
Diaphoresis
Lightheadedness

The board may describe a patient with diabetes who has vague epigastric discomfort and sweating. Do not dismiss that as reflux without considering ACS.

FNP Board Trap

Chest pain at rest plus elevated troponin but no ST elevation is NSTEMI, not unstable angina.

Chest pain at rest with no troponin elevation is unstable angina.

ST elevation changes the urgency because STEMI requires rapid reperfusion.

Practice Question

A 59-year-old man presents with chest pressure at rest. His troponin is elevated. EKG shows no ST-segment elevation. Which diagnosis is most consistent with these findings?

A. Stable angina B. Unstable angina C. NSTEMI D. STEMI

Answer: C. NSTEMI

Rationale: NSTEMI presents with ischemic symptoms and elevated cardiac biomarkers without ST-segment elevation. Unstable angina does not have troponin elevation.

4. Atrial Fibrillation: Rate, Rhythm, Anticoagulation, and Stability

Atrial fibrillation is one of the most common arrhythmias you need to know for FNP boards and clinical practice.

The exam usually focuses on four things:

Recognizing AFib on EKG
Determining whether the patient is stable or unstable
Understanding rate versus rhythm control
Knowing when anticoagulation should be considered

EKG Findings in Atrial Fibrillation

Classic EKG description:

Irregularly irregular rhythm
No consistent P waves
Variable R-R intervals

If the board says “irregularly irregular,” think atrial fibrillation until proven otherwise.

First Question: Stable or Unstable?

Before thinking about long-term medications, ask whether the patient is stable.

Signs of instability include:

Hypotension
Altered mental status
Ischemic chest pain
Acute heart failure
Shock
Severe respiratory distress

Unstable AFib requires urgent synchronized cardioversion.

Stable AFib gives you time to think through rate control, rhythm control, anticoagulation, and underlying causes.

Rate Control

Rate control means you are not necessarily trying to convert the patient back to normal sinus rhythm immediately. You are trying to control the ventricular rate.

Common rate control medications include:

Beta-blockers, such as metoprolol
Non-dihydropyridine calcium channel blockers, such as diltiazem or verapamil

Important safety point: avoid non-dihydropyridine calcium channel blockers in patients with HFrEF because they can worsen systolic heart failure.

Rhythm Control

Rhythm control means you are trying to restore or maintain normal sinus rhythm.

Options may include:

Electrical cardioversion
Pharmacologic cardioversion
Antiarrhythmic medications
Ablation in selected patients

Rhythm control may be considered in highly symptomatic patients, newly diagnosed AFib in certain cases, patients who do not tolerate rate control, or patients with heart failure affected by AFib.

Stroke Prevention

Atrial fibrillation increases stroke risk because blood can pool in the atria, especially the left atrial appendage, leading to clot formation.

For boards, know that stroke risk is commonly assessed with the CHA₂DS₂-VASc score.

CHA₂DS₂-VASc includes:

Congestive heart failure
Hypertension
Age
Diabetes
Stroke or TIA history
Vascular disease
Sex category

Patients with higher risk scores are more likely to need anticoagulation.

Direct oral anticoagulants are commonly preferred over warfarin for many patients with nonvalvular AFib, unless the patient has a mechanical heart valve or moderate-to-severe mitral stenosis.

Do Not Forget Bleeding Risk

Bleeding risk matters, but bleeding risk alone does not automatically mean “no anticoagulation.”

It means you need to identify modifiable bleeding risks, use shared decision-making, and choose therapy carefully.

FNP Board Trap

The board may give you a patient with AFib and ask about aspirin for stroke prevention.

Aspirin is not considered adequate stroke prevention for most patients with AFib who meet criteria for anticoagulation.

Another trap: if the patient is unstable, do not pick oral rate control as the first step. Unstable AFib requires urgent synchronized cardioversion.

Practice Question

A 76-year-old patient presents with palpitations. EKG shows an irregularly irregular rhythm with absent P waves. Blood pressure is 86/54, and the patient is confused and diaphoretic. What is the best next step?

A. Start oral metoprolol B. Start aspirin C. Urgent synchronized cardioversion D. Schedule outpatient cardiology follow-up

Answer: C. Urgent synchronized cardioversion

Rationale: This patient has atrial fibrillation with hemodynamic instability, including hypotension and altered mental status. Unstable AFib requires urgent synchronized cardioversion.

5. Peripheral Artery Disease: Claudication, ABI, and Risk Reduction

Peripheral artery disease is a high-yield vascular topic because it tests your ability to recognize atherosclerotic disease outside the heart.

PAD is not just a leg problem.

It is a systemic atherosclerosis warning sign.

Patients with PAD are at increased risk for cardiovascular events, so management is not only about leg pain. It is also about reducing heart attack, stroke, limb ischemia, and amputation risk.

Classic PAD Symptom

The classic symptom is intermittent claudication.

This is leg pain, cramping, aching, or fatigue that:

Occurs with exertion
Usually affects the calves, thighs, or buttocks
Improves with rest
Returns when activity resumes

The phrase “pain with walking that improves with rest” should make you think PAD.

PAD Physical Exam Findings

Common findings include:

Diminished or absent peripheral pulses
Cool extremity
Delayed capillary refill
Pallor with elevation
Dependent rubor
Hair loss on lower legs
Shiny skin
Thickened nails
Nonhealing wounds on toes or feet
Arterial ulcers, often punched-out and painful

ABI: The Board-Favorite Test

The ankle-brachial index is a key diagnostic test for PAD.

For boards, know these ABI categories:

ABI 1.00–1.40: Normal ABI 0.91–0.99: Borderline ABI 0.90 or less: Abnormal and consistent with PAD ABI greater than 1.40: Noncompressible vessels; consider toe-brachial index

If the patient has classic claudication symptoms and ABI is normal or borderline, exercise ABI testing may be needed.

PAD Management

Management includes both symptom improvement and cardiovascular risk reduction.

Key interventions include:

Smoking cessation
Structured or supervised exercise therapy
Antiplatelet therapy when appropriate
High-intensity statin therapy when appropriate
Blood pressure control
Diabetes management
Foot care education
Cilostazol for claudication symptoms in selected patients

Important safety point: cilostazol should not be used in patients with heart failure.

PAD vs. Spinal Stenosis

This is a very common board-style distinction.

PAD claudication: Pain occurs with walking and improves with rest.

Neurogenic claudication from spinal stenosis: Pain may improve with sitting, bending forward, or leaning over a shopping cart.

If the question says the patient feels better when leaning forward, think spinal stenosis.

If the question says the patient feels better simply by stopping activity and resting, think PAD.

PAD Red Flags

Refer urgently or send for emergency evaluation if the patient has signs of acute limb ischemia.

Think of the six Ps:

Pain
Pallor
Pulselessness
Paresthesia
Paralysis
Poikilothermia

Acute limb ischemia is a vascular emergency.

FNP Board Trap

Do not order a venous Doppler as the best initial test for classic exertional calf pain relieved by rest.

Venous Doppler evaluates for DVT.

Classic claudication points to PAD, and the board-favorite diagnostic test is ABI.

Practice Question

A 64-year-old smoker reports cramping calf pain when walking two blocks. The pain resolves after several minutes of rest. Pedal pulses are diminished. What is the best initial diagnostic test?

A. D-dimer B. Venous Doppler ultrasound C. Ankle-brachial index D. Lumbar spine MRI

Answer: C. Ankle-brachial index

Rationale: Exertional calf pain relieved by rest is classic intermittent claudication. The ankle-brachial index is the initial diagnostic test commonly used to evaluate suspected PAD.

How to Study Cardiology for FNP Boards

Cardiology is not a topic you should study passively.

Reading alone is not enough.

You need to move through cardiology in layers:

Step 1: Read the Core Concept

Start with the book or review content.

Your goal is not to memorize every sentence. Your goal is to understand the pattern.

Ask yourself:

What does this condition look like?
What is the classic board clue?
What is the first-line treatment?
What is the dangerous finding?
What answer choice would trick me?

Step 2: Use Active Recall

After reading, close the book and force yourself to recall the major points.

For example:

What are the stages of hypertension?
What EF defines HFrEF?
What separates unstable angina from NSTEMI?
What does irregularly irregular mean?
What ABI result suggests PAD?

If you cannot recall it without looking, you do not own it yet.

Step 3: Do QBank Questions

This is where the learning actually becomes board-ready.

Do board-style cardiology questions and read every rationale.

Do not only review the questions you missed. Review the ones you got right too, especially if you guessed.

For every missed question, write down why you missed it:

Did I not know the content?
Did I miss a keyword?
Did I confuse two similar diseases?
Did I choose a treatment before assessing stability?
Did I ignore a contraindication?

Step 4: Identify Weak Patterns

If you keep missing ACS questions, do not just “review cardiology.”

Get specific.

Review:

Stable angina vs unstable angina
NSTEMI vs STEMI
Troponin interpretation
Nitro contraindications
Emergency referral language

Specific review fixes weak areas faster than rereading an entire chapter.

Step 5: Retest

After reviewing, test yourself again.

The goal is not to feel familiar with cardiology.

The goal is to answer cardiology questions correctly under exam conditions.

Final Thoughts: Cardiology Is Learnable

Cardiology feels overwhelming when you study it as one giant subject.

But it becomes much more manageable when you break it into board-tested patterns.

For FNP boards, focus on:

Diagnosing and staging hypertension
Recognizing heart failure symptoms and EF categories
Separating stable angina, unstable angina, NSTEMI, and STEMI
Managing atrial fibrillation based on stability and stroke risk
Identifying PAD through claudication and ABI testing

You do not need to know everything.

You need to know what is high-yield, what is dangerous, and what the board is really asking.

Read. Recall. Practice questions. Review rationales. Find your weak areas. Repeat.

That is how you turn cardiology from overwhelming into manageable.

And that is how you walk into boards with more confidence.
