NR511 MIDTERM EXAM

An adult has upper respiratory symptoms and cough for the past 14 days. What should be considered? (Pertussis) Pertussis should always be considered in adults who present with acute cough of greater than 5 days’ duration. The incubation period for pertussis is about 7-10 days. Patients present with URI symptoms for 1-2 weeks. The classic paroxysmal cough usually begins in the second week of the illness. The duration of symptoms and cough are about 3 months even when treated with antibiotics. This is highly infectious and is a reportable disease. Mycoplasma pneumoniae is: (a disease with extrapulmonary manifestations) Mycoplasma is an atypical pathogen and produces atypical pneumonia. It can be difficult to diagnose because symptoms can be varied and involve multiple body systems (extrapulmonary manifestations). Infection with Mycoplasma may present with a normal white blood cell count, maculopapular rash, GI symptoms, tender joints and aches, and, though rare, cardiac rhythm disturbances. Respiratory symptoms may not be pronounced. On chest X-ray there are some unique findings (peribronchial pattern) with Mycoplasma. These include thickened bronchial shadow, streaks of interstitial infiltration, and atelectasis. These are more likely to occur in the lower lobes. Which medication below is contraindicated in an asthma patient because it may increase risk of sudden death if used alone? (Long-acting bronchodilator) A long-acting bronchodilator can be used to treat asthma when it is used in combination with an inhaled steroid. Otherwise, using a long-acting bronchodilator like salmeterol is contraindicated. There is an increased risk of sudden death with asthma exacerbations when this class is used solo to treat asthma. The other choices can be used to treat asthma. Choices vary depending on the patient.
