Medical Tests NREMT Online Questions & Answers

• Question 191:

  A laceration, spurting bright red blood most likely means what type of injury.

  A. Venous
  B. Arterial
  C. Capillary
  D. Amputation
  B. Arterial

  ---

  Explanation/Reference:

  The brighter the blood the more oxygen it holds, Because arterial blood comes from the heart it is rich in oxygen.

• Question 192:

  You are performing rescue breaths using an Ambu bag attached to 100% O2, after several breaths you notice the patients O2 saturation has dropped significantly. What should you do next?

  A. Increase the rate of respirations
  B. Reposition the patients head
  C. Change the seal on the mask
  D. Remove the oral airway from the patients mouth
  B. Reposition the patients head

  ---

  Explanation/Reference:

  This is a sign that you are not getting effective respirations, you should reposition the patient head using the head tilt / chin lift or jaw thrust maneuver and attempt respirations against.

• Question 193:

  What is the name of the reference used to determine the initial response to a Hazardous Materials (HazMat) incident?

  A. the Shipping Paper
  B. the Material Safety Data Sheet
  C. CHEMTREC
  D. the DOT Emergency Response Guide
  D. the DOT Emergency Response Guide

  Explanation/Reference:

• Question 194:

  Anaphyltic shock is a form of distributive shock where the blood vessels _____.

  A. Dilate
  B. Constrict
  C. Leak
  D. Semipermible
  A. Dilate

  ---

  Explanation/Reference:

  Due to the chemical release from the immune system bronchioles constrict and blood vessels to dilate dropping the blood pressure. Capillaries become permeable and leak a little causing hives to form on the skin. Distributive shock is difficult to recognize in the field, heart rate remains relatively low, skin is flushed due to the dilatation of the blood vessels.

• Question 195:

  You are in charge of devising an ambulance deployment plan for the EMS system within your community. Your goal is to minimize response times while simultaneously using all of the EMS resources in an efficient and cost effective manner.

  As such, which of the following information would be most valuable in formulating a plan?

  A. Location of previous ambulance collisions
  B. Time and location of calls over last 5 years
  C. Average age of the population
  D. Socioeconomic status of neighborhoods
  B. Time and location of calls over last 5 years

  ---

  Explanation/Reference:

  Determining the time and location of calls over the past five years is critical, since analysis may reveal patterns to which the appropriate number of EMS resources can be matched. If an increase in the number of motor vehicle collisions is seen during morning rush hour, additional units can be deployed to strategic locations so that they can readily access future incidents. Socioeconomic status may be linked to call volume and time, but by itself is not the best criterion for location of resources. Location of previous ambulance collisions is important data, and should be used to minimize collisions, not locate ambulances. While the average age of the population provides a larger picture of the medical needs of the community, as a whole it is not the best factor in dictating the deployment of resources.

• Question 196:

  Cardiac arrest in children is most commonly due to ____.

  A. a heart attack
  B. respiratory failure
  C. internal bleeding
  D. a congenital heart defect
  B. respiratory failure

  ---

  Explanation/Reference:

• Question 197:

  The first part of conducting an initial assessment is to get a general impression of the patient(s).

  A. True
  B. False
  A. True

  ---

  Explanation/Reference:

• Question 198:

  Which of these lists examples of the deadly dozen chest injuries?

  A. esophageal injury, myocardial contusion, airway obstruction
  B. emphysema, flail chest, cardiac tamponade
  C. pulmonary embolism, esophageal injury, tension pneumothorax
  D. airway obstruction, pulmonary embolism, pulmonary contusion
  A. esophageal injury, myocardial contusion, airway obstruction

  ---

  Explanation/Reference:

• Question 199:

  This type of seizure activity is absent of large muscle contractions, often just starring off in space.

  A. Petit mal
  B. Febrile
  C. Focal motor
  D. Grand mal
  A. Petit mal

  ---

  Explanation/Reference:

  Petit mal seizures are generally thought of as absence of seizure activity. They usually present with the young patient starring off in space with little to no muscle contractions. Petit mal seizures are generally short in nature and there is usually no postictal period, the patient just wakes up and realizes that something happened.

• Question 200:

  An oral and nasal airway should be:

  A. Cleaned well for reuse after the run
  B. Inserted in all critically injured patients
  C. Used to keep the tongue from blocking the airway
  D. used in order to prevent the need for suctioning
  C. Used to keep the tongue from blocking the airway

  ---

  Explanation/Reference:

  While unconscious the tongue has a tendency to fall back in the mouth and block the airway. An oral or nasal airway is used to prevent this.
