Which of the following statements is false?
A) Determining horizontal angulation is the same for both the bisecting and the paralleling techniques.
B) Vertical angulation is accomplished by directing the central ray parallel to the image receptor.
C) Angulation is changed by rotating the tube head horizontally and vertically.
D) To change horizontal angulation, the tube head is swiveled from side to side.
B
Explanation: A) Vertical angulation is accomplished by directing the central ray perpendicular to the image receptor in the paralleling technique and perpendicular to the imaginary bisector when using the bisecting technique.
B) Vertical angulation is accomplished by directing the central ray perpendicular to the image receptor in the paralleling technique and perpendicular to the imaginary bisector when using the bisecting technique.
C) Vertical angulation is accomplished by directing the central ray perpendicular to the image receptor in the paralleling technique and perpendicular to the imaginary bisector when using the bisecting technique.
D) Vertical angulation is accomplished by directing the central ray perpendicular to the image receptor in the paralleling technique and perpendicular to the imaginary bisector when using the bisecting technique.

You are teaching some Emergency Medical Responders (EMRs) to use the Jump START system of triage. Which one of the following comments made by an EMR requires you to intervene and provide corrective instruction?
A) "I like the Jump START system since it uses the same categories of assessment as the START system of triage." B) "If we have a young child injured in a multiple-casualty incident, I will use the Jump START system to triage him." C) "The Jump START system allows me to classify the patient according to his ability to ambulate, his breathing, perfusion, and mental status." D) "The Jump START system is very effective since it allows me to take 2 minutes to assess the patient."
