Ace your nursing finals with this comprehensive master test
bank specifically engineered for the NSG 4100 Adult Health III
course. This high-yield study package features rigorous, NCLEX-
style multiple-choice questions covering advanced neurological
emergencies, complex hemodynamics, mechanical ventilation,
and multi-system trauma protocols. Every practice question is
fully detailed with the correct answers highlighted in italics and
accompanied by robust, bolded rationales to guarantee maximum
retention and conceptual clarity.
Module 1: Neurological Emergencies &
Advanced Neuro (Questions 1-15)
Q1. A neuro-ICU nurse is caring for a patient who
sustained a severe traumatic brain injury. The
patient's intracranial pressure (ICP) monitoring
system shows a reading of 24 mmHg. Which
provider order should the nurse execute first?
A) Administer 100 mg of oral phenytoin via
nasogastric tube.
B) Obtain a routine portable chest X-ray.
C) Administer prescribed intravenous Mannitol
20% over 20 minutes.
, D) Perform extensive endotracheal suctioning
for 30 seconds.
Rationale: A normal ICP is 5 to 15 mmHg. An
ICP of 24 mmHg represents intracranial
hypertension requiring immediate
intervention. Mannitol is an osmotic diuretic
that draws fluid out of the cerebral tissue
into the vascular space, rapidly decreasing
cerebral edema and reducing ICP. Deep or
prolonged suctioning will further elevate ICP.
Oral phenytoin is for long-term seizure
prophylaxis and will not acutely lower ICP.
Q2. Following a supratentorial craniotomy, how
should the nurse position the patient to optimize
cerebral venous drainage and minimize
intracranial pressure?
A) Trendelenburg position with the head turned
to the operative side.
B) Flat (0 degrees) with the neck flexed tightly
toward the chest.
C) Head of the bed elevated 30 to 45 degrees
with the neck in a neutral, midline position.
D) Prone position with a soft pillow under the
lower abdomen.
, Rationale: Elevating the head of the bed
(HOB) to 30–45 degrees utilizes gravity to
promote venous outflow from the cerebral
vault, effectively minimizing ICP. Maintaining
a neutral, midline neck position prevents
jugular vein compression, which would
otherwise obstruct venous return and
dangerously elevate intracranial pressure.
Neck flexion or turning the head drastically
impairs outflow.
Q3. A patient admitted with an acute
subarachnoid hemorrhage exhibits a sudden
change in mental status, a widening pulse
pressure, bradycardia, and irregular respirations.
The nurse recognizes this triad of symptoms as
an indication of what process?
A) Developing hypovolemic shock.
B) Herniation of the brain stem due to severely
increased ICP.
C) An expected transient phase of spinal shock.
D) Incipient septic shock from a nosocomial
infection.
Rationale: Cushing’s Triad consists of
bradycardia, hypertension (typically with a
, widening pulse pressure), and irregular or
bradypneic respirations. It is a late and
ominous sign of advanced intracranial
hypertension, signaling that the brain is
about to herniate or is actively herniating
through the foramen magnum. This is a
neurosurgical emergency.
Q4. A client with severe head trauma develops
profound polyuria, excreting 300 mL of dilute
urine per hour for three consecutive hours. The
urine specific gravity is 1.002, and the serum
sodium is 152 mEq/L. Which neuroendocrine
complication does the nurse suspect?
A) Syndrome of Inappropriate Antidiuretic
Hormone (SIADH).
B) Acute Tubular Necrosis (ATN) secondary to
hypotension.
C) Primary hyperaldosteronism.
D) Central Diabetes Insipidus (DI).
Rationale: Central Diabetes Insipidus is
caused by a deficiency of Antidiuretic
Hormone (ADH) resulting from injury to the
hypothalamus or posterior pituitary gland
during head trauma. The lack of ADH
