Q
  1. You are called to a residence for a 74-year-old woman who fainted. During your assessment, the patient’s son tells you that he was standing next to his mother when she fainted and that he caught her before she fell to the floor. He further tells you that his mother has angina and kidney disease. The patient is now conscious but confused. Her blood pressure is 80/50 mm Hg, pulse is 110 beats/min and weak, and respirations are 22 breaths/min and regular. As your partner administers supplemental oxygen to the patient, you should:
    A) assess for the presence of a nitroglycerin patch on the patient and remove it if she is wearing one.
    B) quickly establish vascular access and administer a 20-mL/kg bolus of an isotonic crystalloid.
    C) obtain a detailed list of all of the patient’s medical problems and the medications that she is taking.
    D) perform a rapid head-to-toe assessment to determine if she has gross injuries or any hidden conditions.

Q
  1. You are assessing an 80-year-old man who complains of generalized weakness. He denies chest pain or shortness of breath and tells you that he has become progressively weaker over the past 3 days. His medical history is significant for two prior heart attacks, hypertension, chronic renal insufficiency, and atrial fibrillation. His blood pressure is 108/60 mm Hg, pulse rate is 94 beats/min and irregular, and respirations are 20 breaths/min and unlabored. Auscultation of his lungs reveals scattered crackles, and the ECG reveals atrial fibrillation. In addition to administering supplemental oxygen, you should:
    A) start an IV with D5W, assess his blood glucose level, and administer half the usual dose of diltiazem to lower the rate of his atrial fibrillation.
    B) obtain a 12-lead ECG tracing, start an IV line with normal saline and give a 250-mL fluid bolus, reassess his blood pressure, and transport him.
    C) establish vascular access, administer 2 mg of morphine to treat his apparent pulmonary edema, continue to monitor the ECG, and transport.
    D) obtain a 12-lead ECG tracing, assess his blood glucose level, establish vascular access and set the rate to keep the vein open, and transport to the hospital.

B)  heart failure.
C)  hypoglycemia.
D)  a pulmonary embolism.

Q
69.  A 71-year-old man with a history of emphysema, coronary artery disease, and hypertension presents with increased shortness of breath and fatigue. His oxygen saturation is 80% on home oxygen at 2 L/min via nasal cannula. His blood pressure is 140/76 mm Hg, pulse rate is 104 beats/min, and respirations are 28 breaths/min and labored. His medications include an albuterol inhaler, prednisone, hydrochlorothiazide, and lisinopril. Auscultation of his lungs reveals scattered wheezing in all fields. Which of the following prehospital interventions is NOT indicated for this patient?
A)  Nebulized ipratropium
B)  Subcutaneous epinephrine
C)  High-flow oxygen therapy
D)  Continuous positive airway pressure

Q
  1. You are dispatched to an assisted living center for an 80-year-old woman who is vomiting bright red blood. Upon your arrival, you find the patient sitting in a chair. She is conscious and alert, but is markedly pale and diaphoretic. Her medical history is significant for hypertension, congestive heart failure, type 2 diabetes, hypothyroidism, and osteoarthritis. Her medications include Toprol, lisinopril, Glucophage, Synthroid, and ibuprofen. Her blood pressure is 76/56 mm Hg, pulse is 76 beats/min and weak, and respirations are 24 breaths/min and shallow. Which of the following statements regarding this scenario is MOST correct?
    A) You should suspect shock due to lower gastrointestinal bleeding, start two large-bore IV lines, and rapidly infuse normal saline until her systolic blood pressure is greater than 90 mm Hg.
    B) Gross hematemesis suggests gastrointestinal bleeding; however, although she is in shock, you should avoid infusing isotonic crystalloid solutions due to her congestive heart failure.
    C) This patient, who is in shock, probably has a bleeding peptic ulcer secondary to ibuprofen use, and the lack of compensatory tachycardia is likely the result of the beta blocker she is taking.
    D) This patient’s vital signs are clearly the result of the medications she is taking, and you should focus on the likelihood that her pallor and diaphoresis are most likely the result of hypoglycemia.

Q
  1. An 82-year-old man presents with confusion that has worsened progressively over the past 2 weeks. Because of his confusion and the fact that he is hearing impaired, you obtain the majority of your medical history information from his daughter. She tells you that her father has high blood pressure but refuses to take medication for it. She also tells you that she thinks he fell about 3 weeks ago, although he denies falling. The patient’s blood pressure is 168/98 mm Hg, pulse rate is 60 beats/min and occasionally irregular, and respirations are 22 breaths/min and regular. This patient MOST likely:
    A) has an acute onset of dementia.
    B) is experiencing a subdural hematoma.
    C) had a stroke secondary to atrial fibrillation.
    D) has normal age-related physiologic changes.

Q
72.  The son of a 76-year-old woman called 9-1-1 because his mother is “ill.” The patient presents with mild confusion, poor skin turgor, and tachycardia. She is incontinent of urine and asks you for a glass of water. Her son tells you that she had not been feeling well for the past several weeks, but would not allow him to take her to the doctor. Which of the following assessment parameters will MOST likely reinforce your suspicion regarding the underlying cause of this patient's condition?
A)  Blood glucose
B)  Cardiac rhythm
C)  Orthostatic vital signs
D)  Cincinnati stroke scale

Q
73.  You respond to a residence for an unknown emergency involving an 83-year-old man. When you arrive, you find the patient, who is conscious and alert, sitting on his couch with his head held over a bowl. He tells you that his nose started bleeding about 20 minutes ago and he cannot get it to stop. As your partner assists the patient in controlling the bleeding, you inquire about his medical history. He tells you that he has chronic atrial fibrillation, has high blood pressure, and is occasionally depressed. When you ask him about compliance with his medications, he tells you, “I take my medicine every day, but the writing on the bottles is so small.” The patient's blood pressure is 112/58 mm Hg, pulse rate is 88 beats/min and irregular, and respirations are 18 and unlabored. This patient has MOST likely inadvertently:
A)  overdosed on his Xanax.
B)  underdosed on his Toprol.
C)  underdosed on his digoxin.
D)  overdosed on his warfarin.

Q
  1. During your assessment of a 79-year-old woman who was involved in a motor vehicle crash, you find that she is responsive to pain only and is breathing with a marked reduction in tidal volume. Your rapid assessment reveals that she has ecchymosis and crepitus over several of her ribs. You should:
    A) avoid any form of positive-pressure ventilation, as this may cause barotrauma and a pneumothorax.
    B) stabilize her fractured ribs with bulky dressings and administer high-flow oxygen via nonrebreathing mask.
    C) immediately secure her airway with an endotracheal tube because she is at increased risk for aspiration.
    D) assist her ventilations with a bag-mask device, delivering just enough volume to produce visible chest rise.

Q
  1. You respond to the residence of a 68-year-old man with terminal cancer. As you begin your assessment, the patient’s wife tells you that he has an out-of-hospital do not resuscitate order, and hands you a document that appears to be valid. The patient, who is clearly emaciated, is conscious but is in severe pain. Your MOST appropriate action should be to:
    A) advise the wife that the do not resuscitate order prohibits you from rendering any prehospital care.
    B) recall that do not resuscitate orders are invalid in the prehospital setting and be prepared to provide full ACLS.
    C) provide supportive care, administer narcotic analgesia as indicated, and transport the patient to the hospital.
    D) accept the stipulations of the do not resuscitate order, obtain a signed refusal from the wife, and return to service.
