A patient comes to the clinic with a 2-day history of cough and wheezing. The patient has no previous history of asthma. The patient reports having heartburn for several months, which has worsened considerably.
 
  The primary care NP makes a diagnosis of asthma and orders oral steroids and inhaled albuterol. The patient's condition worsens, and a chest radiograph obtained 2 days later shows bilateral infiltrates. The NP has failed to: a. confirm the diagnosis.
  b. determine the aggressiveness of therapy.
  c. prescribe an adequate dose of medications.
  d. allow the drugs an adequate amount of time to work.
