Q
  1. You are dispatched to a residence for a 29-year-old woman with difficulty breathing. The patient was recently diagnosed with leukemia and has just completed her first round of chemotherapy and radiation therapy. Upon arriving at the scene, you find the patient sitting in a recliner. Her level of consciousness is markedly diminished and her breathing is shallow. Her husband, obviously frightened, pleads with you to do something. You should:
    A) move her to the floor and open her airway.
    B) assess her carotid pulse for rate and regularity.

Q
  1. You are transporting a 55-year-old woman to the hospital. The patient has lymphoma and complains of generalized, severe pain. She is receiving supplemental oxygen and has an IV line of normal saline established. Her blood pressure is 110/64 mm Hg, pulse rate is 104 beats/min and regular, and respirations are 22 breaths/min and adequate. You should:
    A) ensure that she is in a comfortable position and administer a 250-mL saline bolus.
    B) provide emotional support, but refrain from analgesia as this may cause hypotension.
    C) give her 2 to 5 mg of a benzodiazepine sedative and provide constant reassurance.

Q
  1. You are transferring a 60-year-old man with COPD from a community hospital to a metropolitan hospital. The patient is mildly dyspneic, but is otherwise stable. He is receiving oxygen via nasal cannula, has an IV line of normal saline in place, and has an ECG applied. When reading his chart, you note that he has polycythemia, a history of a prior stroke, and hypertension. The patient tells you that he feels a fluttering sensation in his chest. You glance at the cardiac monitor and see a narrow complex tachycardia at a rate of 160 beats/min. The patient’s blood pressure is 116/70 mm Hg and he remains conscious and alert. You should:
    A) carefully auscultate his lung sounds and then administer a 500-mL bolus of normal saline solution.
    B) administer 5 mg of midazolam, perform synchronized cardioversion with 50 joules, and reassess his cardiac rhythm.
    C) ensure adequate oxygenation and ventilation, administer 6 mg of adenosine, and reassess his cardiac rhythm.
    D) place the patient supine, elevate his legs 6 to 12 inches, and administer 150 mg of amiodarone over 10 minutes.

Q
  1. You receive a call to a residence for a patient who is “sick.” Upon arriving at the scene, you find the patient, a 39-year-old woman, lying on the couch with a wet washcloth on her forehead. She is conscious and alert, and tells you that she has had several episodes of diarrhea and noticed bright red blood in her stool. Her pulse rate is rapid and weak, her skin is cool and clammy, and her blood pressure is 98/58 mm Hg. Her medical history is significant for hemophilia, for which she is receiving factor VIII therapy. As you pull out a nonrebreathing mask, she tells you that her husband will be home in a few hours and that he will take her to the hospital. You should:
    A) notify her husband, explain the situation to him, and advise him that you will be transporting his wife to the hospital.
    B) advise her that her condition dictates immediate transport to the hospital and that delaying transport could result in death.
    C) tell her that her condition is critical and that you are legally required to transport her to the closest appropriate medical facility.
    D) ask her to sign a refusal of EMS transport form, have a neighbor sit with her until her husband gets home, and then return to service.

Q
  1. A 23-year-old woman with sickle cell disease presents with severe joint pain and a fever of 102.5°F. She is conscious and alert, and tells you that her symptoms began yesterday and suddenly worsened today. Her blood pressure is 118/76 mm Hg, pulse rate is 120 beats/min and regular, and respirations are 24 breaths/min with adequate depth. After applying high-flow oxygen and initiating transport, you should:
    A) obtain a 12-lead ECG tracing, start a large-bore IV line, administer a 20-mL/kg normal saline bolus, and reassess her blood pressure.
    B) monitor her oxygen saturation and cardiac rhythm, start an IV line with normal saline, administer 1 µg/kg of fentanyl, and reassess her vital signs.
    C) establish vascular access, administer 2 to 5 mg of midazolam, monitor her cardiac rhythm, and notify the receiving facility as soon as possible.
    D) ensure that she is in a comfortable position, cover her with a blanket, start an IV line at a keep-vein-open rate, and monitor her throughout transport.
