• Question 111:

  What is the most common spinal injury associated with improper lifting techniques?

  A. Thoracic
  B. Cervical
  C. Lumbar
  D. Sacral
  C. Lumbar

  ---

  Explanation/Reference:

  The most common spinal injury is injury to the cervical spine, but improper lifting techniques result in lumbar injuries. Common lumbar injures are buldging and/or compressed vertebra. You must remember to lift with your legs and knees and not your back.

• Question 112:

  The normal heart rate for a child over the age of 6 is:

  A. 140- 160
  B. 120- 140
  C. 100- 120
  D. 80- 100
  D. 80- 100

  ---

  Explanation/Reference:

  The normal heart rate for a newborn is 140- 160 and an infant's is 120- 140 beats per minutes. Children between the ages of 1-6 have a heart rate of 100- 120, while children over the age of 6 have a heart rate of 80- 100 BPM

• Question 113:

  What is the best description of the National Incident Management System (NIMS)?

  A. NIMS is the command structure to dictate an emergency response.
  B. NIMS provides guidelines and common terms to allow multiple agencies to work together.
  C. NIMS is used to prevent incidents from occurring.
  D. NIMS provides a framework for the federal government to take responsibility for an incident.
  B. NIMS provides guidelines and common terms to allow multiple agencies to work together.

• Question 114:

  What is the maximum flow rate for a Nasal Cannula?

  A. 2 lpm
  B. 8 lpm
  C. 12 lpm
  D. 6 lpm
  D. 6 lpm

  ---

  Explanation/Reference:

  A nasal cannula used to administer O2 at flow rates from 2 - 6 LPM, delivering an O2 concentration so 28 - 44%

• Question 115:

  The tongue often is a source of airway obstruction, it falls back and occludes the _________?

  A. Larynx
  B. Trachea
  C. Nasopharynx
  D. Pharynx
  D. Pharynx

  ---

  Explanation/Reference:

  The pharynx or throat is often occluded by the tongue falling back and obstructing air flow. When air enters the nostrils it passes through the nasopharnx then the oropharnx the pharynx before it enters the trachea. Jaw thrust or chin lift will pull the tongue off the back of the pharynx to open the airway allowing air flow to the lungs. The trachea is too distal for the tongue to occlude the trachea

• Question 116:

  Which patient is showing signs and symptoms of cardiac compromise?

  A. 85-year-old man: difficulty breathing, high fever, rapid pulse
  B. 72-year-old woman: wheezing, labored breathing, tightness in throat
  C. 53-year-old woman: dull chest pain, sudden sweating, difficulty breathing
  D. 51-year-old man: headache, dizziness, gagging, chest pain
  C. 53-year-old woman: dull chest pain, sudden sweating, difficulty breathing

  ---

  Explanation/Reference:

  This woman shows classic signs of cardiac compromise: dull chest pain, sudden onset of sweating, and difficulty breathing.

• Question 117:

  You have been called to the top of a mountain resort for a patient that is complaining of a sudden onset of shortness of breath and coughing. Your assessment of the patient reveals an anxious patient with basilar crackles in his lungs. The patient's vital signs include a heart rate of 136, respirations of 28, and a blood pressure of 176/94 mmHg.

  What is your field diagnosis of this patient?

  A. High altitude pulmonary edema
  B. New onset congestive heart failure
  C. Pneumonia
  D. High altitude congestive heart failure
  A. High altitude pulmonary edema

  ---

  Explanation/Reference:

  High-altitude pulmonary edema (HAPE) usually occurs in an unacclimatized individual who rapidly ascends to an altitude that exceeds 8,000 feet. HAPE develops as a result of increased pulmonary pressure and hypertension caused by changes in blood flow at high altitudes.

• Question 118:

  You are transporting a 48-year-old male patient between medical facilities...

  During the history, you learn that the patient was involved in a fall at work and suffered a hip fracture and a head injury. The patient is now presenting with labored breathing at 30/min that has progressively worsened over the last 24 hours, a

  heart rate of 104, and a blood pressure of 98/70. On auscultation, you hear diffuse rales. The patient denies any complaints of pain other than those related to his recent fall.

  What is the most likely cause of the patient's respiratory distress?

  A. Cardiogenic shock
  B. Congestive heart failure
  C. Acute bronchitis
  D. Adult respiratory distress syndrome
  D. Adult respiratory distress syndrome

  ---

  Explanation/Reference:

  Adult respiratory distress syndrome involves non-cardiogenic pulmonary edema that presents 12-72 hours post injury or surgery. Congestive heart failure and cardiogenic shock, while they may occur from the ARDS, have an initial cardiac compromise. Flash pulmonary edema has a rapid onset and deterioration over as little as 30 minutes and is associated with renal dysfunction.

• Question 119:

  You are called to the scene and find a 10-year-old boy on the ground experiencing severe generalized muscle twitching. His mother states he has a diagnosis of epilepsy and his seizure started four minutes ago. He is most likely experiencing what type of seizure?

  A. generalized tonic-clonic seizure
  B. status epilepticus
  C. an aura
  D. a simple partial seizure
  A. generalized tonic-clonic seizure

  Explanation/Reference:

• Question 120:

  Which of the following ventilatory techniques is likely to yield the LOWEST tidal volumes?

  A. One person bag-valve-mask
  B. Two person bag-valve-mask
  C. Flow restricted oxygen powered ventilatory device
  D. Mouth-to-mask
  A. One person bag-valve-mask

  ---

  Explanation/Reference:

  With both mouth-to-mouth and mouth-to-mask ventilation, it is relatively easy to maintain a good seal with the patient s mouth, allowing for delivery of adequate tidal volumes. Likewise, two person bag-valve-mask techniques dedicate one rescuer solely to ensuring adequate mask seal and the second rescuer to squeeze the ventilation bag with two hands (again allowing for adequate tidal volumes to be delivered). One person bag-valve-mask usage is a difficult technique to master, as the single rescuer must maintain a manual airway maneuver, an adequate mask seal, and squeeze the bag simultaneously.
