  A. HIV or AIDS
  B. Tuberculosis
  C. Open wounds
  D. Hepatitis B
  B. Tuberculosis

  ---

  Explanation/Reference:

  High-efficiency particulate air (HEPA) respirators

  are worn when in contact with patients who have airborne infections, such as tuberculosis. HIV/AIDS and hepatitis B are both blood borne pathogens. Contaminants from open wounds would also be blood borne.

• Question 12:

  The way a patient is injured is often referred to as the _______________?

  A. Mechanism of injury
  B. Mechanics of injury
  C. Injury pattern
  D. Energy transfer
  A. Mechanism of injury

  ---

  Explanation/Reference:

  The mechanism of injury transfers energy to the patient causing a pattern of injury which is predictable. The way a patient is injured is referred to as the Mechanism of injury a frontal impact auto accident is the mechanism of injury. This allows the clinician to predict the type of injuries the patient may have and predict their response to treatment. Injury pattern can be predicted by looking a the mechanism of injury.

• Question 13:

  You arrive at the scene of en elderly women who has fallen and injured her ribs. She is breathing very rapidly at a rate of 40 and shallow. How is this a serious life threat?

  A. She is inhaling to much oxygen
  B. Her minute volume may be diminished
  C. Her minute volume may is excessive
  D. She has exceeded her dead space
  C. Her minute volume may is excessive

  ---

  Explanation/Reference:

  In her current state the patient may not be moving enough for adequate tissue perfusion

• Question 14:

  You are dispatched to a 75-year old female patient who is currently in cardiac arrest. After one shock via the AED she begins breathing at 15 breaths per minute, and has a strong carotid pulse; what is your next step?

  A. Assist ventilations with a bag-valve mask
  B. Provide supplemental oxygen by NRB
  C. Continue to administer shocks via AED
  D. Request a non-transport and leave the scene
  B. Provide supplemental oxygen by NRB

  ---

  Explanation/Reference:

  The next step after shocking with the AED, and the patient is breathing and has a pulse is to apply high concentration oxygen via NRB, unless the respiratory rate is above or below the minimum and maximum limits, at which time you would assist with a bag valve mask.

• Question 15:

  You’re treating an adult patient who is wearing a non-rebreather. The reservoir bag collapses on inspiration. What action(s) should you take?

  A. Make sure the bag is connected to an O2 source and the flow is at least 10 LPM.
  B. Switch to a nasal cannula.
  C. Tell the patient to relax and breathe slower.
  D. Tell the patient to take deeper breaths and blow out harder.
  A. Make sure the bag is connected to an O2 source and the flow is at least 10 LPM.

  B. Angina pestoris
  C. Acute myocardial infarction
  D. Arteosclerosis
  A. Sudden death

• Question 18:

  The lower airway ends at the Alveoli, gas exchange occurs at this level. Oxygen moves to the hemoglobin by passing through a semipermible membrane. Name this membrane.

  A. Capillary bed
  B. Bronchioles
  C. Capillary blood
  D. Veinule
  A. Capillary bed

  ---

  Explanation/Reference:

  The bronchi sub divide into smaller and smaller passages, they end with tiny air sacs called alveoli. The alveoli are covered in capillaries, this is where the gas exchange occurs. The carbon dioxide moves off of the hemoglobin and oxygen moves to the hemoglobin by diffusion. Movement of a gas from a higher concentration to a lower concentration. At the level of the capillaries is where the arteries switch to veins, capillaries are so small only one blood cell can pass through at a time.

• Question 19:

  What is meant by minute volume?

  A. The number of breaths/minute minus the dead space in the lungs.
  B. The amount of air inhaled in one breath times the breaths per minute.
  C. The quantity of air that can be taken into the lungs in one breath, or else known as lung capacity.
  D. The amount of air taken in by the lungs over a two-minute period.
  B. The amount of air inhaled in one breath times the breaths per minute.
