ANSWERS|BRAND NEW 2026-2027
UPDATE|GRADED A+
Question 1
When monitoring ICP in an adult, the trauma nurse must be aware the normal range is:
a. <5
b. <10
c. <15
d. <20
CORRECT ANSWER
C. Less than or equal to 15
-7-15 supine in an adult
-If bleeding occurs within the brain, the brain first attempts to compensate by decreasing
the volume of CSF through increased absorption and decreasing blood blow, but when
the brain can no longer compensate, the ICP begins to rise very rapidly, resulting in
compression of the tissue and sometimes brain shift and herniation syndromes. If the
condition is not immediately reversed, it can result in death within a very short period of
time.
Question 2
A patient with a gunshot wound to the abdomen, the trauma nurse should anticipate that
the organ most likely to be injured is the
a. colon
b. stomach
c. liver
d. Small intestine
1
,CORRECT ANSWER
D: Small intestine
With a GSW to the abdomen the trauma nurse should anticipate that the organ most
likely to be injured is the small intestine (majority of the time)
Question 3
A 38 year old male receives mannitol to decrease ICP resulting from a TBI and exhibits
cardiac arrhythmias. Which of the following electrolyte abnormalities associated with
mannitol administration is most likely the cause of arrhythmias?
a. hyperkalemia
b. hypokalemia
c. hypernatremia
d. hypermagnesemia
CORRECT ANSWER
A: hyperkalemia
Mannitol is administered for treatment of cerebral edema, it may result in fluid and
electrolyte imbalance with hyperkalemia which can cause cardiac arrhythmias.
Question 4
What is mannitol?
CORRECT ANSWER
treatment for cerebral edema
2
, Mannitol is an osmotic diuretic that increases excretion of both sodium and water, which
will then cause increase in potassium levels, but will helped reduce intracranial pressure
and brain mass in TBI patients.
Side effects: nausea, vomiting, hypotension, tachycardia, fever and urticaria
Question 5
If a handgun is found in the pocket of a trauma victim, the first consideration when
removing and securing the gun is to:
a. place it in a paper bag
b. arrange for security personnel to remove the gun.
c. avoid touching the trigger
d. call the police
CORRECT ANSWER
C: avoid touching the trigger
All guns should be considered loaded so avoiding touching the trigger is the first
consideration.
The gun should be removed wearing gloves and handled carefully to avoid disturbing
fingerprints or gun powder residue. It should be placed in a secure container, never a
paper bag.
Question 6
If a patient with facial fractures has dentoalveolar trauma with avulsion of permanent
teeth, reimplantation should ideally be carried out within:
3
