Key Concepts
Introduction
Primary-care NP decisions You risk-stratify using integrated clinical picture—vitals, oxygenation, age, comorbidities, pregnancy, frailty, and social determinants—before choosing outpatient antibiotics versus ED referral. Boards punish home antibiotics for patients who need IV fluids, oxygen, or monitoring. Follow-up discipline Specify when to return for worsening dyspnea, new hypoxia, inability to tolerate oral meds, confusion, or hemodynamic instability—vague “call if worse” without time-bound reassessment loses points. Expect next step items: CXR when diagnosis uncertain with high risk, empiric therapy selection when bacterial pneumonia likely, hospital referral when severity tools or clinical picture demand it, and sepsis recognition when hypotension and end-organ dysfunction appear. Traps • Treating viral bronchitis with antibiotics without bacterial pneumonia features. • Ignoring hypoxia or tachypnea in older adults who “look okay.” • Missing pregnancy as a modifier for drug choice and threshold to escalate. For NP certification preparation (United States), questions rarely announce the topic in the first sentence. They hide it inside vitals, labs, and a short story. Your job is to name the clinical problem, justify why it matters now, and select the safest next step...
