NURS 495: Evolve Med Surg Practice Prep with
Detailed Rationales
Course Code: NURS 495
Course Name: Advanced Medical-Surgical Nursing Practicum
Topic: Cranial Nerve Disorders, Cardiovascular Pathology, Oncological
Screenings, and Metabolic Derangements
Academic Year: 2026/2027
1. A patient presents to the emergency department reporting paroxysms of
sudden, stabbing, severe pain over the lip and chin that feels like an
electric shock whenever the lower face is touched or stimulated. The nurse
recognizes that these findings are highly characteristic of which neurological
pathology?
A. Ménière's disease affecting the 8th cranial nerve
B. Trigeminal neuralgia (tic douloureux) affecting the 5th cranial nerve
C. Bell's palsy affecting the 7th cranial nerve
D. Hypoglossal nerve degradation affecting the 12th cranial nerve
CORRECT ANSWER: B
RATIONALE: Trigeminal neuralgia (tic douloureux) is a sensory disorder of
the 5th cranial nerve (trigeminal nerve) characterized by excruciating paroxysms
of sudden, stabbing, severe pain over the lip, chin, cheek, or forehead, often
triggered by minimal mechanical stimulation like talking, chewing, or washing the
face. Tinnitus and vertigo characterize Ménière's disease (8th cranial nerve). Facial
paralysis defines Bell's palsy (7th cranial nerve), and disorders of the hypoglossal
nerve (12th cranial nerve) manifest as speech and swallowing difficulties.
2. A 77-year-old female patient is admitted with profound confusion, complete
anorexia, nausea, and vomiting. Telemetry monitoring reveals sinus
bradycardia with an apical pulse of 43 beats per minute. What is the
priority question the nurse should ask the family on admission to evaluate
for a drug-induced toxic crisis?
A. "Does the patient utilize a nitroglycerin patch for chest pain?"
B. "Has the patient been taking high doses of aspirin for arthritis?"
, C. "Does the patient take digitalis (digoxin) for heart failure at home?"
D. "Does the patient use any magnesium-based antacids for chronic
indigestion?"
CORRECT ANSWER: C
RATIONALE: Older adult patients are highly susceptible to digitalis (digoxin)
toxicity due to age-related declines in glomerular filtration. Classic systemic signs
of digoxin intoxication include anorexia, nausea, vomiting, confusion, headache,
and severe bradycardia (apical pulse < 60 bpm). Asking "Does the client take
digitalis?" is the immediate assessment priority to guide treatment choices.
Aspirin or nitroglycerin usage does not cause this specific triad of bradycardia and
gastrointestinal distress.
3. While monitoring a female patient receiving an geographic infusion of
vasopressin for an active esophageal variceal rupture, the patient suddenly
complains of severe substernal tightness and pressure across her chest.
Which protocol should the nurse anticipate initiating immediately to
counteract this adverse drug action?
A. Increase the vasopressin infusion rate to tamponade the vessels.
B. Initiate an intravenous nitroglycerin infusion according to prescribed
parameters.
C. Perform a nasogastric lavage using iced normal saline.
D. Prepare the patient for immediate endotracheal intubation.
CORRECT ANSWER: B
RATIONALE: Vasopressin is a potent systemic vasoconstrictor utilized to
reduce portal pressure and stop variceal bleeding. A dangerous adverse effect is
coronary artery vasoconstriction, which restricts myocardial blood supply,
causing ischemia manifested as substernal chest tightness or pressure. To
counteract this, the nurse should immediately initiate an IV nitroglycerin
infusion to induce coronary vasodilation while preserving portal hemodynamics.
Increasing the vasopressin will worsen myocardial ischemia, and saline lavage will
not address the coronary crisis.
4. A patient with a 16-year history of diabetes mellitus undergoes renal
screening for worsening fatigue. Laboratory values show an elevated blood
urea nitrogen (BUN) and serum creatinine. Which clinical manifestation
should the nurse identify as an early symptom of progressive renal
, insufficiency?
A. Severe acute dyspnea on exertion
B. Nocturia resulting from a loss of concentrated urine
C. Profound uremic encephalopathy confusion
D. Stomatitis with a distinct urinous odor
CORRECT ANSWER: B
RATIONALE: In the early stages of renal insufficiency, as nephrons are
progressively lost, the kidneys lose their baseline ability to concentrate urine. This
results in polyuria and nocturia, forcing the patient to urinate frequently
throughout the night. Dyspnea, uremic confusion, and stomatitis are late-stage
manifestations corresponding to end-stage renal disease (ESRD) and severe
uremia.
5. An elderly woman is admitted to the orthopedic unit after tripping over an
object in her house. X-rays reveal a fracture in the proximal end of her
femur. Which predisposing diagnostic condition is the most probable cause
of this fragility?
A. Failure of visual accommodation
B. Renal osteodystrophy
C. Osteoporosis resulting from hormonal changes
D. Widespread microvascular brain infarctions
CORRECT ANSWER: C
RATIONALE: The most common cause of a fractured hip in elderly women is
osteoporosis resulting from reduced calcium in the bones as a result of
hormonal changes (such as decreased estrogen production after menopause).
Failing eyesight may contribute to an environmental fall but does not cause
structural bone fragility. Renal osteodystrophy is associated with chronic renal
failure rather than standard aging.
6. A nurse is assisting a client out of bed for the first time following a major
abdominal surgical procedure. Which action should the nurse implement
first?
A. Position a chair at a right angle to the bedside frame.
B. Instruct the patient to perform deep breathing exercises.
C. Allow the client to sit with the bed in a high Fowler's position.
D. Assist the client to swing and dangle their legs over the bedside.
