A medical resident is evaluating four different patients admitted to the general internal medicine service. Match each patient's clinical presentation with the most appropriate immediate diagnostic or therapeutic step based on current clinical guidelines.
- A 72-year-old man with severe COPD presents with increased dyspnea, increased sputum volume, and purulence. His arterial blood gas reveals a pH of 7.26 and a PaCO2 of 68 mmHg.Initiate non-invasive positive pressure ventilation (NIPPV) alongside standard medical therapy.
- A 24-year-old woman with type 1 diabetes presents with severe nausea, abdominal pain, a blood glucose of 480 mg/dL, and an anion-gap metabolic acidosis.Administer rapid intravenous isotonic fluid resuscitation followed by a continuous regular insulin infusion.
- A 65-year-old woman presents with fever, productive cough, and a new lobar infiltrate. She is hemodynamically stable, has no recent hospitalizations, and lacks risk factors for MRSA or Pseudomonas.Initiate targeted therapy with a beta-lactam plus a macrolide, avoiding unnecessary broad-spectrum coverage.
- A 45-year-old man presents with profound fatigue, orthostatic hypotension, hyponatremia, and hyperkalemia. Confirmatory endocrine laboratory testing is drawn and pending.Administer immediate intravenous hydrocortisone without waiting for confirmatory test results.
Cevap
The correct matches align each specific clinical syndrome with its most critical guideline-indicated management step: the COPD exacerbation with respiratory acidosis requires NIPPV; the DKA patient requires isotonic fluids and continuous insulin; the uncomplicated CAP patient requires targeted narrow-spectrum antibiotics; and the patient in suspected adrenal crisis requires immediate empiric hydrocortisone.
Each correct pair links a classic internal medicine presentation to its most critical, evidence-based intervention. The COPD patient meets strict criteria for NIPPV due to acute respiratory acidosis. The DKA patient strictly requires fluids and continuous insulin to correct the life-threatening metabolic acidosis. The CAP patient should receive standard empiric therapy based on modern antibiotic stewardship principles. The patient with suspected adrenal crisis requires immediate, empiric hydrocortisone administration.
