A
An older man complains of chest pain. He is conscious and alert and denies any other symptoms. Your focused assessment of this PT should include:
A) palpation of the upper Abdominal quadrants, vital signs, auscultation of breath and epigastric sounds, and assessment of his BG level.
B) vital signs, looking at the chest for obvious trauma, auscultation of breath sounds, assessing the external jugular veins, and assessing for edema to the extremities.
C) evaluation of his hydration status, vital signs, determining if he is experiencing unilateral neurologic deficits, asking him to smile to determine if he has facial droop.
D) neurologic function in all extremities, vital signs, auscultation of heart sounds, inquiring about his family hx, and assessing his pupils for equality and reactivity.
B
An important neurotransmitter in the parasympathetic nervous system is:
A) acetylcholine
B) dopamine
C) epinephrine
D) norepinephrine
A
When the diaphragm and intercostal muscles contract:
A) atmospheric pressure draws air out of the lungs
B) intrapulmonary and atmospheric pressures are equal
C) intrapulmonary pressure falls below atmospheric pressure
D) atmospheric pressure exceeds intrapulmonary pressure
C
Your rapid assessment of an injured PT reveals pelvic deformity and a rigid, distended abdomen. After applying high flow O2 and immobilizing the PT’s spine you should:
A) perform a secondary assessment and transport immediately
B) obtain vital signs, initiate IV, transport promptly
C) establish an IV line, obtain SAMPLE HX, transport
D) transport promptly and initiate IV en route to hospital
D
You note little movement of an apneic PT’s chest when you and your partner are ventilating with the 2 person bag mask technique. You should:
A) use a flow-restricted, O2 powered ventilation device
B) reassess the position of the PT’s airway and readjust if needed
C) insert a multilumen airway device and continue bag mask ventilations
D) continue ventilating the PT and reassess him or her in 2 minutes.
B
Epinephrine is classified as a/an:
A) sympatholytic
B) parasympatholytic
C) antiadrenergic
D) sympathomimetic
D
A 63 y/o male is being transported to the hospital for an acute exacerbation of his emphysema. He is on O2 via nasal cannula at 4 L/min. During your reassessment, you note that his mental status has deteriorated and his respirations have become markedly slow and shallow. You should:
A) immediately reassess his vital signs
B) assess his blood glucose level
C) insert an advanced airway device at once
D) assist ventilations with a bag mask device
D
A young male is found to be unconscious. When assessing his pupils, you note that they dilate when exposed to bright light. This clinical finding is MOST suggestive of:
A) a hemorrhagic stroke
B) congenital anisocoria
C) depressed brain function
D) a barbiturate overdose
C
A 30 y/o male was ejected from his car after hitting a tree at a rate of speed. Your assessment reveals that he is pulseless, apneic, and has multiple systems trauma. Treatment for his PT includes all of the following EXCEPT:
A) applying an AED and defib if indicated
B) immediate transport to the closet trauma center
C) chest compressions and advanced airway management
D) large bore IV with normal saline or lactated ringer
