MARYVILLE NURS 623 ADVANCED PHARMACOLOGY
EXAM 300 ACTUAL TESTBANK QUESTIONS AND CORRECT
ANSWERS WITH RATIONALE LATEST 2026 ALREADY
GRADED A+
The Maryville NURS 623 Advanced Pharmacology exam comprehensively
assesses advanced practice nursing knowledge of pharmacotherapeutics
across major drug classes and clinical conditions. Key topics include
neurology (Parkinson's, Alzheimer's, seizures, neuropathic pain, headaches),
psychiatry (depression, anxiety, bipolar disorder, schizophrenia, substance
use disorders), endocrinology (diabetes, thyroid disorders), and pain
management. The exam tests understanding of mechanisms of action, adverse
effects, drug interactions, contraindications, and patient-specific
considerations such as renal dosing, pregnancy safety, and elderly
precautions. Questions emphasize clinical application, evidence-based
prescribing, and monitoring parameters essential for safe, effective
pharmacotherapy in diverse patient populations across the lifespan.
1. A 62-year-old patient calls with a headache. Which statement should cause the
most concern?
A. "It's a dull ache that worsens as the day goes on."
B. "It's the worst headache I've ever had."
C. "I have a headache with some nasal congestion."
D. "The headache is worse when I bend over."
Answer: B
Rationale: A sudden, severe headache described as "the worst headache of my life"
is a classic presentation of a subarachnoid hemorrhage or other intracranial
emergency. This "thunderclap" headache requires immediate evaluation to rule out
life-threatening conditions . The other options describe more typical tension, sinus,
or positional headaches.
2. A patient presents with an abrupt onset of unilateral facial paralysis with
inability to close the eyelid, normal ocular movement, and loss of taste. Which
cranial nerve is affected?
A. Cranial Nerve V (Trigeminal)
B. Cranial Nerve VII (Facial)
,C. Cranial Nerve VIII (Vestibulocochlear)
D. Cranial Nerve IX (Glossopharyngeal)
Answer: B
Rationale: Bell's palsy is characterized by acute, unilateral facial paralysis affecting
Cranial Nerve VII (Facial nerve), with symptoms including facial droop, loss of
taste (dysgeusia), postauricular pain, and sound sensitivity (hyperacusis).
Importantly, the patient cannot close the eyelid, creating risk for corneal drying
and ulceration . Normal ocular movement distinguishes it from stroke.
3. What is the most serious risk for a patient with Bell's palsy?
A. Permanent facial droop
B. Loss of ability to blink and close the eyelid
C. Loss of taste permanently
D. Hearing loss
Answer: B
Rationale: In Bell's palsy, the patient loses the ability to blink and close the eyelid
on the affected side, which subjects the cornea to drying and potential ulceration .
Patient teaching should include use of artificial tears and eye protection to prevent
this complication. The condition is typically self-limiting with recovery over 3-6
months .
4. The cardinal features of Parkinson's disease are best remembered by the
mnemonic TRAP. What does the "T" stand for?
A. Tachycardia
B. Tremor at rest
C. Tics
D. Trismus
Answer: B
Rationale: The cardinal features of Parkinson's disease are Tremor at rest (often
described as "pill-rolling"), Rigidity, Akinesia/Bradykinesia, and Postural
disturbances (TRAP) . Tremor at rest is a characteristic early finding that
differentiates Parkinson's from other movement disorders.
5. Which finding is characteristic of "freezing phenomenon" in a patient with
Parkinson's disease?
A. Inability to initiate movement, especially when starting to walk
B. Tremor that worsens with purposeful movement
C. Rapid, shuffling gait
D. Dystonic posturing of the hands
Answer: A
,Rationale: "Freezing phenomenon" is a characteristic feature of Parkinson's disease
where the patient experiences sudden, temporary inability to initiate movement,
most commonly when starting to walk or turning . This can lead to falls and
significant functional impairment.
6. For a patient with newly diagnosed Alzheimer's disease, which category of
medication should be initiated?
A. NMDA receptor antagonists only
B. Cholinesterase inhibitors
C. Antipsychotics
D. Benzodiazepines
Answer: B
Rationale: At the onset of Alzheimer's disease, cholinesterase inhibitors (donepezil,
rivastigmine, galantamine) should be initiated as first-line pharmacologic treatment
. These medications work by increasing acetylcholine levels in the brain and may
improve cognitive function or slow decline. NMDA receptor antagonists
(memantine) are typically used in moderate to severe stages.
7. Which of the following is a key distinguishing feature of delirium compared to
dementia?
A. Gradual, progressive onset over months to years
B. Abrupt onset over hours to days with reversible causes
C. No change in level of consciousness
D. Irreversible cognitive decline
Answer: B
Rationale: Delirium is characterized by abrupt onset (hours to days), underlying
acute cause, and is potentially reversible. Key features include hallucinations,
incoherent speech, and confusion . Dementia has a gradual onset (months to years)
with progressive and typically irreversible cognitive decline. The change in level
of consciousness is a hallmark of delirium not present in dementia.
8. A patient presents with unilateral headache, jaw claudication (pain with
chewing), and temporary blindness. What condition should be suspected?
A. Migraine with aura
B. Temporal arteritis (Giant Cell Arteritis)
C. Cluster headache
D. Tension headache
Answer: B
Rationale: Temporal arteritis (Giant Cell Arteritis) presents with unilateral
headache (temporal artery distribution), jaw claudication (pain with chewing), and
, temporary vision loss . It is a medical urgency due to risk of permanent blindness.
It is more common in patients over age 50 and is often associated with
polymyalgia rheumatica (pain and stiffness in shoulders and hips) .
9. Which diagnostic maneuver is most useful in a patient with suspected lumbar
radiculopathy?
A. Phalen's test
B. Straight leg raise test
C. McMurray's test
D. Lachman's test
Answer: B
Rationale: The straight leg raise test assesses for L5-S1 nerve root irritation and is
the most useful diagnostic maneuver for lumbar radiculopathy. Pain with straight
leg raise indicates the most common disc herniation . Phalen's test is for carpal
tunnel syndrome, McMurray's for meniscal injury, and Lachman's for ACL injury.
10. A patient is diagnosed with a classic migraine. Which symptom is
characteristic of this type of headache?
A. Bilateral, non-pulsating tightening pain
B. Unilateral, pulsatile headache with nausea and photophobia
C. Unilateral orbital headache with lacrimation and rhinorrhea
D. Headache preceded by visual aura
Answer: D
Rationale: A classic migraine is preceded by an aura (visual disturbances, flashes
of light, scotomas) that occurs 20 minutes before the headache . Both classic and
common migraines can have unilateral throbbing pain, nausea, vomiting,
photophobia, and phonophobia . The aura distinguishes "classic" from "common"
migraine.
11. Which type of headache is characterized by unilateral, orbital, supraorbital, or
temporal pain accompanied by lacrimation, rhinorrhea, and nasal congestion?
A. Migraine
B. Cluster headache
C. Tension headache
D. Sinus headache
Answer: B
Rationale: Cluster headaches are characterized by severe unilateral pain in the
orbital, supraorbital, or temporal region, accompanied by autonomic symptoms on
the same side including lacrimation (tearing), rhinorrhea (runny nose), and nasal
congestion . These headaches are more common in men and occur in clusters.
