EXAM 3 COMPLETE QUESTIONS
WITH CORRECT ANSWERS
\.1. A patient in the ICU has a malignant brain tumor. Based on
knowledge of the cellular units that make up the nervous system, the
nurse understands that which cell type is the least likely to be the origin
of this patient's tumor?
A) Neuron
B) Astrocyte
C) Ependymal cell
D) Oligodendroglia - ANSWERS-a
\.2. A patient was involved in a car accident and is in hypovolemic
shock, with severe hypotension. Due to damage to the
glossopharyngeal nerve, the baroreceptor reflex is inhibited in the
patient. What effect of this impaired reflex should the nurse expect to
see in this patient?
A) Rapid increase in blood pressure
B) Lack of immediate withdrawal from painful stimuli
C) Lack of compensatory increase in heart rate
,D) Continuance of motor activity in the intestines - ANSWERS-c
\.3. A patient in the ICU, in addition to his critical illness, suffers from
clinical depression and is receiving medication for it. The nurse
understands that this patient's antidepression medications are most
likely to inhibit the reuptake of which of the following
neurotransmitters? Select all that apply.
A) Acetylcholine
B) Endorphin
C) Enkephalin
D) Serotonin
E) Norepinephrine
F) Substance P - ANSWERS-d, e
\.4. A patient in the ICU is receiving an experimental drug to treat a
brain tumor. The nurse understands that which of the following
characteristics would be important in such a drug? Select all that apply.
A) Protein based
B) Lipid soluble
C) Small molecule
D) Water soluble - ANSWERS-b, c
,\.5. A patient in the ICU has suffered severe head trauma as the result
of a diving accident. Damage was sustained only in the frontal lobes of
the brain. Which function is most likely to be impaired with this injury?
A) Breathing
B) Maintain steady posture when standing
C) Sneezing
D) Writing with a pen - ANSWERS-d

cannot walk across the room without assistance. The nurse recognizes
that which sensation is most likely impaired in this patient? A) Visceral
B) Proprioceptive
C) Exteroceptive
D) Visual - ANSWERS-b
\.7. A neurologist is testing a patient's responsiveness to various stimuli.
He pricks the patient's foot with the point of a safety pin, and the
patient jerks her foot back immediately. The nurse recognizes that the
integrative central nervous system component involved in this reflex is
which of the following?
A) Spinal cord interneuron
B) Medulla oblongata
C) Midbrain
, D) Cerebrum - ANSWERS-a
\.8. A patient who experienced severe trauma in a multiple car accident
on the freeway explained that he didn't even notice the pain of his
injuries as he was helping his daughters escape from their burning car.
He asked the nurse what kept him from feeling the pain immediately.
What would be the nurse's best response?
A) The accident occurred when it was cold outside.
B) The patient has fewer nociceptors than normal.
C) The patient has an impaired thalamus.
D) Endogenous opioid peptides blocked transmission of the pain
message to the brain. - ANSWERS-d
\.9. A nurse witnesses a patient having a panic attack in the ICU after
learning that he has terminal lung cancer. Recognizing that he is in the
alarm phase of the general adaptation syndrome, what physiological
adaptations should the nurse expect?
A) Drop in blood pressure
B) Release of cortisol
C) A shock state
D) Heart rate drops from its peak but remains elevated - ANSWERS-b
