PCCN Study Guide — 2026 Edition

Progressive care is, more than anything else, cardiac surveillance. The patients on a progressive care unit are the ones whose hearts are unstable enough to need continuous telemetry and frequent assessment, but stable enough not to need an ICU bed. On the exam, cardiovascular questions reward one skill above all: telling apart conditions that look alike — MI versus unstable angina, tamponade versus tension pneumothorax, cardiogenic shock versus sepsis — and knowing the first action for each.

Acute coronary syndrome

Acute coronary syndrome (ACS) covers the spectrum from unstable angina through NSTEMI to STEMI. The unifying event is familiar: "Most heart attacks are caused by a blood clot that blocks one of the coronary arteries. The coronary arteries bring blood and oxygen to the heart. If the blood flow is blocked, the heart is starved of oxygen and heart cells die." Unstable angina is ischemia without cell death (no troponin rise); NSTEMI and STEMI are myocardial infarction with cell death, distinguished by whether the ECG shows ST elevation.^[1]

The exam loves atypical presentations. "Chest pain is the most common symptom of a heart attack," classically pressure-like, and "The pain most often lasts longer than 20 minutes." But: "Some people (including older adults, people with diabetes, and women) may have little or no chest pain when they have a heart attack. Or, they may have atypical symptoms such as shortness of breath, fatigue, and weakness." A question that describes an older diabetic woman with new fatigue and dyspnea is describing an MI until proven otherwise.^[1]

Management priorities for STEMI: reperfusion, fast. "Angioplasty is often the first choice of treatment. It should be done within 90 minutes after you get to the hospital." Aspirin is given early — "You may receive aspirin, unless it would not be safe for you" — along with anticoagulation, nitrates for pain (watch blood pressure), and morphine only if pain persists. Thrombolytics are the fallback when PCI is unavailable: "best if these medicines are given soon after the onset of symptoms, usually no later than 12 hours after it and ideally within 30 minutes of arriving at the hospital." The trap: thrombolytics are contraindicated with active bleeding, recent stroke, or recent surgery — the exam will offer them to a patient with a GI bleed and expect you to refuse.^[1]

After PCI, watch the access site (hematoma, retroperitoneal bleed after femoral access), monitor for abrupt closure (return of chest pain, ST changes), and remember dual antiplatelet therapy must not be stopped early — stent thrombosis kills.

Heart failure

Heart failure is the heart's inability to pump enough blood to meet the body's needs, in its two flavors: reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). Left-sided failure backs up into the lungs — dyspnea, crackles, cough, pulmonary edema; right-sided failure backs up into the body — jugular venous distension, peripheral edema, hepatomegaly, weight gain. Most progressive care patients have both to some degree.

Daily weights are the single best early warning: "Weight gain and leg swelling, especially over a few day, can be a sign that your body is holding on to extra fluid and your heart failure is getting worse." Teach patients to weigh daily, same scale, same clothes, same time — and to call for a gain of more than 2 pounds in a day or 5 pounds in a week^[2]. Sodium restriction matters because salt holds water: "Limit how much salt you eat."^[3]

Drug therapy you must know cold: ACE inhibitors/ARBs/ARNI, evidence-based beta-blockers (carvedilol, metoprolol succinate, bisoprolol), mineralocorticoid receptor antagonists, and SGLT2 inhibitors for HFrEF; diuretics for volume, not for mortality. Digoxin helps symptoms but has a narrow therapeutic range — toxicity shows as anorexia, nausea, vision changes (yellow-green halos), and arrhythmias, worsened by hypokalemia. The trap: giving a beta-blocker during acute decompensated failure, or stopping it abruptly in a stable patient.

Atrial fibrillation and other arrhythmias

Atrial fibrillation is the most common sustained arrhythmia on progressive care. The atria quiver instead of contracting, so cardiac output drops and blood stagnates — "The irregular heart rhythm that occurs with AFib makes blood clots more likely to form," and clots mean stroke. Management has two arms: rate or rhythm control, and stroke prevention with anticoagulation. "Blood-thinning medicines are often given to reduce the risk of blood clots that can result from ongoing irregular heart rhythms." For patients who cannot safely take anticoagulants, "left atrial appendage occlude (LAAO) devices" are another stroke-prevention option.^[4]

Cardioversion — "Electric shocks to your heart" — "may be used to get the heart back into a normal rhythm right away," either emergently or planned. The exam's favorite trap: cardioverting AFib of unknown duration without anticoagulation first, which can launch a clot to the brain.^[4]

Know your tachyarrhythmias by their response to vagal maneuvers and adenosine: SVT/PSVT often breaks with them; for PSVT, "Emergency treatment to slow the heartbeat back to normal may include: Electrical cardioversion, which is the use of electric shock" or "Medicines through a vein." Ventricular tachycardia with a pulse and instability gets synchronized cardioversion; pulseless VT gets defibrillation and CPR. "If someone with VT is in distress, they may require: Cardiopulmonary resuscitation (CPR), Cardioversion (electric shock)," or IV antiarrhythmics.^{[5, 6, 7]}

Bradyarrhythmias and heart block: symptomatic bradycardia gets atropine first, then transcutaneous pacing, then transvenous pacing as a bridge. A pacemaker "senses when your heart is beating too slowly. It sends a signal to your heart that makes your heart beat at the correct pace." On telemetry, failure to capture means pacing spikes without following QRS complexes — the nurse's response is to check connections, increase output per protocol, and call for help; the patient is effectively bradycardic until capture returns.^[8]

Valvular disease and structural interventions

Aortic stenosis presents with the classic triad of syncope, angina, and dyspnea; mitral stenosis with dyspnea, hemoptysis, and atrial fibrillation from left atrial enlargement. A new murmur after MI suggests papillary muscle rupture or ventricular septal defect — both surgical emergencies.

TAVR has changed the landscape: for aortic stenosis, a catheter can "implant an artificial valve ( transcatheter aortic valve replacement or TAVR)"^[9]. Progressive care nurses see these patients post-procedure. "The risks of heart valve replacement include stroke , blood clots, damage and bleeding where the catheters were inserted, and injury to the kidneys or the heart"^[10] — so the nurse checks neurologic status and the access site and watches the rhythm on telemetry. The mitral clip repairs the mitral valve percutaneously for selected patients with mitral regurgitation.^[9]

Endocarditis prophylaxis and diagnosis: vegetations on valves throw emboli; risk factors include prosthetic valves and IV drug use — "contaminated needles can introduce bacteria into the bloodstream" is the mechanism the exam expects you to name. Blood cultures before antibiotics, then prolonged IV antibiotics.^[11]

Aortic disease, PAD, and hypertension

Aortic dissection is the can't-miss diagnosis: sudden tearing chest pain radiating to the back, blood pressure different between arms, pulse deficits. Management is heart rate and blood pressure control (esmolol then vasodilators) to reduce shear stress, then surgery for ascending (Type A) dissections. Abdominal aortic aneurysm is often silent until rupture — sudden severe abdominal/back pain with hypotension is rupture until proven otherwise.

Peripheral arterial disease is atherosclerosis of the limb arteries: intermittent claudication, cool pale extremity, diminished pulses, and pallor on elevation with dependent rubor. The ankle-brachial index (ABI) below 0.90 confirms PAD. Contrast with venous disease: edema, brownish skin changes, ulcers at the medial ankle. The trap: elevating a PAD leg worsens ischemia; dependency helps arterial flow.

Hypertension staging drives treatment: readings "140/90 mm Hg or higher" are Stage 2, where medication is typically started, while 130–139/80–89 is Stage 1. Hypertensive emergency (evidence of acute target-organ damage) needs controlled IV reduction — not normalization, which can infarct the brain or heart.

Pericardial disease, myocarditis, and cardiomyopathy

Pericarditis pain is positional — worse lying flat, better sitting up and leaning forward — which distinguishes it from MI. Pericarditis can progress to tamponade, and tamponade physiology is the exam favorite: "Cardiac tamponade is pressure on the heart that occurs when blood or fluid builds up in the space between the heart muscle and the outer covering sac (pericardium) of the heart." Findings include "Heart sounds [that] are only faintly heard through a stethoscope," "Neck veins that may be bulging (distended) but the blood pressure is low," and blood pressure that falls with inspiration. "Cardiac tamponade is an emergency condition that needs to be treated in the hospital. The fluid around the heart must be drained as quickly as possible" — by pericardiocentesis, "A procedure that uses a needle to remove fluid from the tissue that surrounds the heart."^[12]

Myocarditis (often post-viral) presents like MI with clean coronaries; cardiomyopathy is classified by structure — dilated, hypertrophic, restrictive — and heart failure management follows.

Cardiogenic shock and hemodynamic monitoring

Cardiogenic shock is pump failure: hypotension with signs of poor perfusion — "Cold and clammy skin," oliguria, altered mentation, rising lactate. It complicates large MI, severe heart failure, and post-cardiotomy states. Management supports the pump (inotropes, vasopressors if vasodilated too) while reducing its work — diuretics and vasodilators for pulmonary edema, and revascularization for MI-related shock. Fluids are given cautiously, in small boluses with reassessment, because the failing ventricle cannot handle volume.

Arterial lines give beat-to-beat pressure; a damped waveform means re-zero, check for kinks, and flush. Central venous pressure reflects right-sided filling. The exam tests the nursing actions — leveling the transducer at the phlebostatic axis, zeroing, reading at end-expiration — more than the numbers.

Key takeaways

• Atypical MI (older adults, diabetes, women): dyspnea, fatigue, weakness without chest pain.
• STEMI: aspirin early, PCI within 90 minutes; thrombolytics only if PCI unavailable and no bleeding contraindications.
• HF: daily weights catch decompensation early; more than 2 lb in a day or 5 lb in a week means call.
• AFib: control rate/rhythm AND prevent stroke with anticoagulation; don't cardiovert prolonged AFib without anticoagulation coverage.
• Tamponade: faint heart sounds + distended neck veins + hypotension = drain it now.
• Cardiogenic shock: cold, clammy, oliguric hypotension — support the pump, don't drown it.
• Dissection: tearing pain to the back, unequal pressures — control heart rate and BP first.
