1. Which drug for Alzheimer's disease should be administered
beginning at the time of diagnosis?
A) Cholinesterase inhibitors
B) Anxiolytics
C) Antidepressants
D) Atypical antipsychotics
Correct Answer: A
Expert Rationale: Cholinesterase inhibitors should be administered beginning
at the time of diagnosis for Alzheimer's disease. These drugs work by inhibiting
the breakdown of acetylcholine in the brain, which helps slow cognitive decline.
They are most effective when started early in the disease process.
Test-Taking Tip: Alzheimer's diagnosis = start cholinesterase inhibitors
immediately. Early treatment preserves cognitive function.
2. Most adult poisonings are:
A) Intentional and self-inflicted
B) Accidental
C) Caused by someone wishing to do harm to the person
D) Not attributed to any reason
Correct Answer: B
Expert Rationale: Most adult poisonings are accidental. While intentional
,overdoses do occur, the majority of poisoning cases in adults result from
unintentional exposure to toxins, medication errors, or accidental ingestion.
Test-Taking Tip: Most adult poisonings = accidental. Don't assume intentional
unless evidence suggests otherwise.
3. A 58-year-old woman presents with a breast mass. Which of the
following responses by the clinician would be most appropriate?
A) "It is probably just a cyst, because that is the most common breast mass."
B) "We will order a mammogram and ultrasound to help establish a diagnosis."
C) "We will go ahead and schedule you for a biopsy because that is the only way
to know for sure."
D) "Because your lump is painful, it is most likely not cancer."
Correct Answer: B
Expert Rationale: The most appropriate response is to order a mammogram
and ultrasound to help establish a diagnosis. This is the standard diagnostic
approach for a breast mass, as imaging can differentiate between benign and
malignant lesions. Biopsy is reserved for suspicious findings.
Test-Taking Tip: Breast mass = mammogram + ultrasound first. Don't reassure
or jump to biopsy without imaging.
4. Which of the following is a specific test for multiple sclerosis (MS)?
A) MRI of the brain and spine
B) Lumbar puncture with oligoclonal bands
C) Evoked potentials
D) There is no specific test
Correct Answer: D
,Expert Rationale: There is no specific test for multiple sclerosis (MS).
Diagnosis is based on clinical findings, MRI, lumbar puncture, and evoked
potentials, but no single test is definitive. MS is a clinical diagnosis supported by
laboratory and imaging findings.
Test-Taking Tip: MS = no specific test. Diagnosis is clinical + supportive tests.
5. Which characteristic of delirium helps to distinguish delirium from
dementia?
A) Abrupt onset
B) Impaired attention
C) Affective changes
D) Delusions
Correct Answer: A
Expert Rationale: Abrupt onset is the characteristic that helps distinguish
delirium from dementia. Delirium develops acutely over hours to days, while
dementia has an insidious onset over months to years.
Test-Taking Tip: Delirium = abrupt onset. Dementia = gradual onset. This is
the key differentiator.
6. Which clinical feature is the first to be affected in increased
intracranial pressure (ICP)?
A) Decrease in level of consciousness (LOC)
B) Headache
C) Nausea
D) Widening pulse pressure
Correct Answer: A
, Expert Rationale: A decrease in level of consciousness (LOC) is the first
clinical feature affected in increased intracranial pressure. Changes in LOC are
the earliest and most sensitive indicator of rising ICP.
Test-Taking Tip: ICP = LOC changes first. Monitor consciousness closely.
7. Jennifer is an 18-year-old girl who comes to the emergency room
after a fall during a soccer game. She has been diagnosed with a
dislocated shoulder. Which of the following statements are true
concerning shoulder dislocation?
A) Posterior dislocations are more common than anterior dislocations
B) There is a risk of neurovascular and neurosensory trauma, so the clinician
should check for distal pulses
C) Shoulder dislocations usually reduce spontaneously
D) X-rays are not necessary before reduction
Correct Answer: B
Expert Rationale: There is a risk of neurovascular and neurosensory trauma
with shoulder dislocation, so the clinician should check for distal pulses. The
axillary nerve and artery are at risk, and thorough neurovascular assessment is
essential before and after reduction.
Test-Taking Tip: Shoulder dislocation = check distal pulses. Neurovascular
assessment is critical.
8. Which of the following signs or symptoms indicate an
inflammatory etiology to musculoskeletal pain?
A) Decreased C-reactive protein
B) Hyperalbuminemia
