It is a beautiful, warm, sunny evening. You are barbecuing steaks on the deck while the potatoes bake in the station oven. You are admiring the sunset and discussing what a great job you have that allows you to get paid for eating a gourmet meal when the tones go off.
You are dispatched to the local ball field for a 30-year-old male patient who is experiencing breathing difficulties. From the ball diamond you would be approximately 10 minutes to the nearest medical facility.
As you arrive on scene, a middle-aged female flags you down.She directs you over to the bench on the side of the playing field. A baseball game is still in progress but poses no threat to you or your patient. You can see a few people gathered around a 30-year-old gentleman who is sitting on the bench, leaning forward, in obvious distress. The people around him are attempting to calm him but they appear anxious as well.
Your patient is leaning forward in obvious respiratory distress with audible wheezing. He acknowledges your presence but appears to be concentrating heavily on breathing. He is able to speak in two-word sentences only. He appears orientated to person, place, time and situation. His friends tell you he was playing baseball and had just hit a home run. After arriving at home plate he appeared to be having difficulty breathing. He sat down on the bench and rapidly worsened to become as you find him. He first began experiencing difficulty approximately 10 minutes prior to your arrival. His friends were preparing to drive him to the hospital but were alarmed at his rapidly worsening condition and phoned you instead. Your patient reports he cannot breath. He states he has a history of asthma. He reports he hasn’t had an attack for approximately six months but his attacks are sometimes brought on by exercise, sometimes by environmental influences such as pollen or dust. He tells you he usually takes his “puffer” when he feels an attack coming on but he left it at home tonight. He reports no drug allergies, although exposure to dust, cats and pollen all have been known to precipitate an asthma attack. He has no other pertinent past medical history. Your patient reports he last ate approximately two hours ago, at which time he had his regular supper meal. He states he felt a slight “tightness” in his chest prior to running the bases. Primary survey reveals respiratory distress with accessory muscle use noted in neck and intercostals. Lung sounds are present in all lobes but wheezing is noted throughout on both inspiration and expiration. There is no J.V.D. or tracheal shift. Palpation of the chest and neck reveal no deformities and does not induce pain. The extremities are unremarkable, capillary refill is delayed. The abdomen is soft, non-distended and non-rigid. There is no edema noted to hands or feet, distal pulses present. Palpation of the head reveals no deformities, there are no rashes or hives, and pupils are equal and reactive to light at 4mm. The secondary survey is unremarkable.

10. Normal lung sounds will reveal:A. Longer inspiration than expiration phaseB. Longer expiration than inspiration phaseC. Equal inspiration and expiration phaseD. None of the above
11. Your initial treatment should consist of:
A. Oxygen at 6 litres via nasal cannulaB. Oxygen at 4 litres via nasal cannulaC. Oxygen high flow via non-rebreather maskD. Transport only, do not give oxygen as it may shut down the patient’s respiratory drive.
12. The tiny air sacs at the ends of the bronchioles are the:A. Bronchi B. PapillaeC. MicrovilliD. Alveoli E. Myocardium
13. A double-walled sac surrounds each lung. It is called the:A. PeritoneumB. MeningesC. Pericardium D. Pleura E. Columna

15. Status asthmaticus is:A. A life threatening prolonged asthmatic attackB. Often characterized by inaudible breath soundsC. Often characterized by decreased rate of respirationsD. All of the aboveE. A and B are correct
16. The E.C.G. reveals:
17. An I.V. for this patient:A. Is contraindicatedB. Should be established as a drug routeC. Should be established to infuse massive volume
18. Pulsus paradoxus, a decline in systolic blood pressure of 10-20 mmHg, may occur in asthmatics. This decline in pressure would occur on:
