Clients with asthma use a peak flow meter to monitor their PEFR and determine their level of asthma control. An optimal PEFR is determined by recording the client's personal best peak flow number during 2 weeks of well-controlled asthma symptoms. Guided by their personal best, clients are taught asthma self-care using peak flow "zones": Green zone (≥80% of personal best): no intervention needed Yellow zone (50%-79% of personal best): intervention needed (eg, short-acting bronchodilator [eg, albuterol]) and/or treatment plan modification by the health care provider) Red zone (<50% of personal best): emergency medical care and short-acting bronchodilators required and hospital admission possible (Option A) (Option B) Clients with small, uncomplicated pneumothoraxes may have a flutter (Heimlich) valve placed but can be safely discharged home. Scant, clear pleural drainage is expected. (Option C) Rifampin, an antibiotic used to treat tuberculosis, may cause reddish-orange body fluids (eg, urine, sweat, tears). This discoloration may stain contact lenses but is harmless. (Option D) Clients with chronic obstructive pulmonary disease (COPD) may be chronically hypoxic and hypercapnic. An oximetry reading of ≥88% is generally acceptable in an asymptomatic client with COPD. Educational objective: Clients with asthma use a peak flow meter to monitor their peak expiratory flow rate because it helps determine their level of asthma control. A client who attains a rate <50% of personal best needs emergency medical care.
