Then answer the questions that follow. You and your EMT partner, Cindy, are assigned to a suburban station on a cold February morning. At 0613 hours, you are dispatched to an apartment building for a patient with a breathing problem. You arrive at the building about 7 minutes later and are met by the patient’s wife, who is quite anxious. You put on your personal protective equipment, get the ambulance cot and your equipment, and follow the woman to the sixth floor of the building. On the way up in the elevator, the patient’s wife tells you that her husband, Mike, is having a very hard time breathing, and he looks a little blue. You arrive at the apartment and find the patient, a 23-year-old man, seated in a chair, leaning forward on his legs. His skin is pale, his lips are cyanotic, and you hear wheezing as he breathes. You introduce yourself and Cindy to the patient as you begin assessing his condition. It is obvious he is quite anxious, so you attempt to calm him as you explain what you are doing. Mike cannot speak in full sentences but tells you that he has had asthma for about 15 years. He usually uses an inhaler but ran out of the medicine about five days ago. His breathing got worse two days ago, when the elevator was not working and he had to climb up the five flights of stairs to his apartment. You obtain a pulse oximeter reading and place the patient on oxygen, using a nonrebreather mask at 15 liters per minute. Cindy begins taking Mike’s vital signs. His blood pressure is 96/74 mmHg; his pulse is 110; and his respirations are 28 breaths per minute. You decide that Mike needs immediate transport to the hospital, about 25 minutes away. As you get Mike settled on your cot, sitting up for comfort, you use your portable radio to request an ALS rendezvous. 1. As you begin patient contact, describe your initial impression, and explain why you feel this way. 2. Is this patient considered a high priority for immediate transport? Explain your rationale. 3. Which signs and symptoms suggest that the patient is having severe respiratory difficulty? 4. Why was an ALS rendezvous requested for this patient? ©2018 by Pearson Education, Inc.

It is possible to add moisture to oxygen by adding a(n) to the regulator. 19.

The trachea is the passageway through which food travels into the stomach. 2. The nose, mouth, pharynx, and trachea are all parts of the respiratory system. 3.

The head-tilt, chin-lift maneuver should be used to open the airway of a patient with a suspected neck injury. 10. When using the head-tilt, chin-lift maneuver to open a patient’s airway, you would place your fingertips on the bony part of the chin, not the soft tissues under the lower jaw. 11. When opening an unconscious patient’s airway, you may need to insert your thumb into the patient’s mouth. 12. When using the jaw-thrust maneuver to open a patient’s airway, you would stabilize the patient’s head with your knees. 13. Use of a pocket mask with supplemental oxygen to ventilate a patient can deliver a higher tidal volume of air than use of a bag-valve-mask device. 14. A pop-off valve is an undesirable feature of some older bag-valve-mask devices. 15. BVMs should have a standard 15/22-mm connection to properly fit face masks and endotracheal tubes. 16. If a nasopharyngeal airway is too long, it can enter the esophagus and cause massive gastric distention. 17. With a BVM device, a mask seal can more easily be maintained when ventilations are performed by two rescuers. 18. Nonbreathing adult patients should be ventilated at a rate of 10–12 breaths per minute. ©2018 by Pearson Education, Inc.

Using a nasal cannula with supplemental oxygen will deliver a nearly 100 percent oxygen concentration to the patient. 21. A pediatric-sized BVM mask can be used to establish a seal around a stoma. 22. Flow-restricted, oxygen-powered ventilation devices may give an audible alarm when the relief valve is activated. 23.

To ease insertion of a nasopharyngeal airway, it should be lubricated with petroleum jelly. 25. The EMT should never suction a patient for more than 5 seconds at a time. ©2018 by Pearson Education, Inc.
