Heart Failure Clinical Reasoning Case Study -
EXAMINATION
Patient Case: Carlos Boccerini, 68-Year-Old Male - Acute Decompensated Heart Failure
2026-2027 Edition - Aligned with Current AHA/ACC/HFSA Guidelines
Nursing and Medical Education Examination | 30 Questions | Single Best Answer (A-D)
Examination Instructions. This examination presents one progressive clinical case with integrated history,
physical examination, and diagnostic data. Each question has ONE best answer. Cognitive distribution: 20% recall,
50% application, 30% analysis. Read each portion of the case in sequence, because new clinical data are revealed as
the case progresses. Distractors represent common heart failure reasoning pitfalls, including physical finding
misidentification, diagnostic misinterpretation, differential diagnosis confusion, treatment prioritization errors, and
patient education gaps.
CASE PRESENTATION - INTEGRATED CLINICAL DATA
Demographics and Chief Complaint
Carlos Boccerini is a 68-year-old retired chef who arrives at the emergency department by ambulance at 09:40
on a Tuesday morning, accompanied by his wife. He is alert but visibly dyspneic, able to speak only in short
sentences, and he repeatedly insists on sitting upright. The triage note records his chief complaint verbatim: 'I
can't catch my breath, especially when I lie down, and my legs are swollen like balloons.' His wife adds that he
has 'not been himself' for about ten days.
History of Presenting Illness
Five days before presentation, Carlos developed progressively worsening breathlessness on exertion: he can no
longer walk to the mailbox without stopping, and climbing the eight steps to his front door requires two rest
periods. His wife notes that he has slept propped on three pillows for the past four nights (previously one), and
on three consecutive nights he woke at approximately 02:00 gasping for air, forced to sit on the edge of the
bed for 20 to 30 minutes until the episode resolved. He reports bilateral ankle and calf swelling that has
'spread up to my knees,' a 4.5 kg (10 lb) weight gain over ten days, increasing fatigue, abdominal bloating, and
a dull ache under his right ribs. Ten days ago he ran out of furosemide 40 mg twice daily and did not request a
refill because 'I felt fine, so I didn't bother.' Four days ago he cooked his signature lasagna, cured meats, and
salt-risen bread for his grandson's birthday party, tasted every dish while cooking, and ate two large servings.
Past Medical, Family, and Social History
Past medical history: anterior STEMI six years ago treated with a drug-eluting stent to the proximal LAD;
chronic heart failure with reduced ejection fraction (baseline LVEF 30%); hypertension for 20 years; type 2
diabetes mellitus for 12 years (most recent HbA1c 7.8%); chronic kidney disease stage 3a (baseline creatinine
1.4 mg/dL, eGFR 50 mL/min/1.73m2); chronic atrial fibrillation, rate controlled on metoprolol; and
hyperlipidemia. He has no prior stroke, no pacemaker or defibrillator, no prior diagnosis of COPD, and no
history of alcohol or substance misuse. Family history: father died of an acute myocardial infarction at age 62;
mother had type 2 diabetes and died at age 79. Social history: retired chef; 30-pack-year tobacco history, quit

immediately after his myocardial infarction six years ago; drinks one to two glasses of wine per week; lives
with his wife in a two-story home; largely sedentary since retirement; admits he still cooks the weekend family
meals 'with plenty of salt because that is how food should taste.'
Home Medications
Table 1. Home Medication List Confirmed With Patient and Wife on Arrival
Medication (Class) Dose Adherence / Notes
Lisinopril (ACE inhibitor) 20 mg twice daily Taking as prescribed
Metoprolol succinate (beta-blocker) 50 mg daily Taking as prescribed
Furosemide (loop diuretic) 40 mg twice daily RAN OUT 10 days ago; not refilled
Spironolactone (aldosterone antagonist) 25 mg daily Taking as prescribed
Apixaban (factor Xa inhibitor) 5 mg twice daily Taking as prescribed
Atorvastatin 40 mg nightly Taking as prescribed
Metformin 1000 mg twice daily Taking as prescribed
Insulin glargine 20 units nightly Taking as prescribed
Ibuprofen (OTC) 200-400 mg as needed Used 2-3 times per week for knee pain
Allergies: no known drug allergies.
SECTION 1: PATIENT PRESENTATION AND HISTORY (Questions
1-7)
Focus: Chief Complaint, History of Presenting Illness, Past Medical History, and Risk Factors
Q1: Based on Carlos's chief complaint and history of present illness, which symptom cluster
most strongly indicates acute decompensated heart failure rather than an alternative cause of
dyspnea?
A. Sudden-onset pleuritic chest pain with hemoptysis and unilateral leg swelling
B. Progressive exertional dyspnea, three-pillow orthopnea, paroxysmal nocturnal
dyspnea, and bilateral pitting edema [CORRECT]
C. Fever with productive purulent sputum and pleuritic pain worsening over 48 hours
D. Chronic wheezing with a dry, non-productive cough that responds to inhaled bronchodilators
Correct Answer: B
Rationale: Orthopnea, paroxysmal nocturnal dyspnea, and bilateral dependent edema form the hallmark
congestive cluster of decompensated biventricular heart failure, driven by elevated left- and right-sided
filling pressures. Option A describes the classic triad of pulmonary embolism, option C describes
community-acquired pneumonia, and option D describes an obstructive airway process such as asthma or
COPD. The gradual five-day progression with nocturnal symptoms localizes the problem to volume
overload rather than acute vascular obstruction or infection.
