EMS 121 EXAM QUESTIONS AND ANSWERS WITH COMPLETE
SOLUTIONS GRADED A++ LATEST UPDATE
You observe the patient as you approach. He is lying faceup. As you look at the
front side of his body, which plane of the body are you observing?
Coronal
After opening the patient's airway and confirming spontaneous respirations, you
check for a pulse on his neck just lateral to the trachea. What artery are you
palpating?
Carotid
You determine the patient has a strong pulse and perform a rapid assessment.
While assessing the lower extremities, you observe marked swelling in the right
thigh. What bone is in this location?
Femur
Which of the following substances is the predominant mineral that the bone cells
use to create a hard and resilient structure?
Calcium
You perform an assessment while en route to the hospital. You note bruising and
instability of the right cheekbone. What is the proper name for this bone?
Zygoma
Which of the following terms is used to describe a balance of all body systems?
Homeostasis
, You are watching your patient carefully to see if her condition deteriorates. What
signs would alert you to the patient going into the next stage of shock?
Signs of decomposated shock include a decreased level of consciousness, ashen or
syanotic skin, thready pulses, labored or irregular respirations, and a systolic blood
pressure of less than 90 mm Hg.
The larger bone of the forearm at the wrist is the:
radius
The forearm makes up part of the elbow. The elbow is an example of what type of
joint?
hinge
Explain what occurs in the body as a result of respiratory compromise.
Respiratory compromise is the inability of the body to move gas effectively. It occurs
when either ventilation or respiration is impaired. The heart and brain cells cannot
survive without a constant supply of oxygen, and will die in minutes. Decreased oxygen
levels force cells to move from aerobic metabolism to anaerobic metabolism. Cellular
functions become impaired. Lactic acid is created as a by-product of anaerobic
metabolism. Once too much lactic acid is created, the pH of the blood will drop, and
cells will die.
On the basis of your assessment findings, you suspect that your patient may
have sustained a closed head injury. What structure of the brain is responsible
for the level of consciousness and maintenance of vital signs?
: The brainstem is the control center that regulates a person's level of consciousness
and vital signs. The brainstem comprises three smaller components: the midbrain,
