L.B. is not in any acute distress. Vital signs (VS) are 110/60, 55, 18
She has no sinus tenderness, ear examination findings are negative, nasal mucosa is pale and boggy, mouth examination findings are negative, there is no cervical adenopathy, and lungs are clear to auscultation. Forced expiration using the peak flow meter (PFM) generates a cough. Her peak flow is 350 L/min with good effort. Expected peak flow for her height and age is 512 L/min, giving a response of 68% of predicted. The provider orders predilator and postdilator pulmonary function tests (PFTs). What is the purpose of completing predilator and postdilator PFTs? After the PFT, L.B. is diagnosed with mild persistent asthma. She returns to the clinic so that a plan for managing her asthma can be established. What priority topics need addressed? How will you describe mild persistent asthma to L.B.? The provider orders triamcinolone (Azmacort) two puffs bid and albuterol (Ventolin) two puffs every 6 hours as needed. What points will you include when teaching L.B. about these medications? L.B. asks, "Why do I have to use this inhaler? Can't I just take some pills?" Your response to L.B. is based on the knowledge that the inhalation route is: a. Safer and more effective than pills b. Less expensive than combination therapy c. Easier to master than oral therapy d. More likely to assist in curing her asthma The provider gives L.B. a prescription for a peak flow meter (PFM). What is a PFM? Give L.B. precise instructions to perform the PFM maneuver. L.B. asks why she has to use the PFM. Explain the purpose of the peak expiratory flow rate (PEFR) measurement, what an asthma action plan is, and the role the PEFR plays in an asthma action plan. You set up an asthma action plan for L.B. What will you teach L.B. to do if her PEFR value falls into the yellow or red zone?
