Respiratory Nursing — Community-Acquired Pneumonia Learning Path

About This Path

The Respiratory Nursing — Community-Acquired Pneumonia Learning Path guides BSN students through the full arc of CAP care: from recognizing the earliest signs of infection through managing a patient who deteriorates to septic shock. The path opens with the CAP case study (Mr. Hannigan), which anchors all subsequent learning in a real clinical scenario, and then sequences pharmacology, clinical judgment, and formative assessment so that each resource reinforces and extends the last.

• CAP Case Study establishes the clinical picture — history, physical findings, diagnostic workup, CURB-65 scoring, and initial management.
• Pharmacology deepens understanding of the antibiotic choices used in the case (levofloxacin, azithromycin, ceftriaxone), including mechanism of action, nursing considerations, and patient education.
• NGN Clinical Judgment applies the NCSBN Clinical Judgment Measurement Model via a bowtie scenario in which CAP progresses to sepsis, requiring students to select correct nursing actions and monitoring parameters under time pressure.
• Formative Assessment consolidates learning through a 20-question NCLEX-NG practice quiz with answer rationales.

Students should complete resources in the listed order. Each resource builds directly on concepts introduced in the resource before it.

What You’ll Learn

Working through this path, students will develop knowledge and skills across all major CAP competency areas:

• Pathophysiology of CAP — alveolar consolidation, ventilation-perfusion (V/Q) mismatch, progressive hypoxemia, and the systemic inflammatory response that drives deterioration to sepsis
• Typical vs. Atypical Pathogen Recognition — distinguishing Streptococcus pneumoniae (rust-colored sputum, lobar consolidation) from atypical organisms such as Mycoplasma pneumoniae, Legionella pneumophila, and Chlamydophila pneumoniae (dry cough, extrapulmonary features, hyponatremia in Legionella)
• CURB-65 Risk Stratification — scoring confusion, BUN, respiratory rate, blood pressure, and age ≥ 65 to guide outpatient vs. inpatient vs. ICU disposition decisions
• Evidence-Based Antibiotic Selection by Severity — outpatient monotherapy vs. combination therapy for hospitalized CAP vs. broad-spectrum IV coverage for ICU-level disease; understanding why antibiotic choice changes with comorbidities and local resistance patterns
• Key Drug Monographs — levofloxacin (respiratory quinolone; QTc monitoring; photosensitivity; tendon rupture risk), azithromycin (macrolide; atypical coverage; cardiac adverse effects; drug interactions), and ceftriaxone (third-generation cephalosporin; biliary sludge; cross-reactivity with penicillin allergy)
• Oxygenation Management and Escalation — nasal cannula → simple face mask → non-rebreather mask → high-flow nasal cannula → non-invasive positive pressure ventilation → mechanical ventilation; target SpO₂ ranges in CAP; positioning strategies (high Fowler’s, prone considerations)
• CAP Complications — parapneumonic effusion and empyema, lung abscess, bacteremia, sepsis and septic shock, acute respiratory distress syndrome (ARDS), and when each complication should be suspected based on clinical trajectory
• Prevention Strategies — pneumococcal vaccination (PCV15/PCV20 vs. PPSV23 schedules), annual influenza vaccination, smoking cessation counseling, and aspiration precautions in high-risk patients
• NGN Clinical Judgment — CAP → Sepsis Bowtie Scenario — applying the NCSBN Clinical Judgment Measurement Model to recognize deterioration, select priority nursing actions, and identify monitoring parameters when CAP progresses to septic shock
• Formative Assessment — CAP NCLEX-NG Practice Quiz — 20 next-generation NCLEX–style questions covering pathophysiology, pharmacology, oxygenation, risk stratification, complications, and prevention with full answer rationales

How to Use This Path

Complete all resources in the order listed. Sequential completion is important because each resource assumes knowledge from prior resources:

1. Start with the CAP Case Study. Read through the full case before reviewing any supplementary materials. Use the encyclopedia entry and study notes as reference while working through the case.
2. Review the Pharmacology Monographs for levofloxacin, azithromycin, and ceftriaxone after completing the case study. Focus on nursing considerations and patient education points that the prescriber will rely on you to provide.
3. Complete the NGN Bowtie Scenario. Apply clinical judgment under the NGN framework. Review the rationale for each selected action and monitoring parameter even if you answer correctly.
4. Take the CAP Practice Quiz. Aim for ≥ 75% on your first attempt. Review all rationales — correct and incorrect — before proceeding.
5. Review the Encyclopedia Entry and Study Notes as needed throughout. These are reference resources; return to them whenever a concept from the case or quiz requires clarification.

Students should achieve ≥ 75% on the CAP Practice Quiz before proceeding to Adult Health clinical rotation.

If you score below 75%, review the study notes and relevant encyclopedia sections, then retake the quiz. If you score below 75% on a second attempt, contact your clinical faculty for a remediation plan before your scheduled clinical day.
