A. Manic episode
B. Hypomanic episode
C. Generalized anxiety disorder
D. Dysthymia

Which medication class is especially associated with falls and confusion in older adults and should be minimized when possible?
A. Benzodiazepines
B. Topical emollients
C. Simple antacids only
D. Topical antibiotics only
Correct Answer: A
Benzodiazepines can cause sedation, cognitive impairment, gait instability and falls, with greater sensitivity in older adults.

An elderly patient repeatedly falls when standing. Which bedside measurement should be checked?
A. Orthostatic blood pressure and pulse
B. Visual acuity only
C. Peak expiratory flow only
D. Abdominal girth only
Correct Answer: A
Orthostatic vital signs help identify postural hypotension, a common reversible contributor to falls in older adults.

A patient on an antipsychotic develops high fever, severe rigidity, autonomic instability and markedly elevated CK. What is the diagnosis?
A. Neuroleptic malignant syndrome
B. Serotonin syndrome
C. Panic attack
D. Alcohol withdrawal
Correct Answer: A
NMS is a life-threatening dopamine-antagonist reaction characterized by hyperthermia, lead-pipe rigidity, autonomic instability and elevated CK.

A. Serotonin syndrome
B. Neuroleptic malignant syndrome
C. Anticholinergic toxicity
D. Opioid withdrawal
Correct Answer: A
Serotonergic excess causes autonomic instability, neuromuscular hyperactivity including clonus, and altered mental state.

An older adult has progressive cognitive decline, visual hallucinations, fluctuating cognition and parkinsonism. What is the most likely diagnosis?
A. Dementia with Lewy bodies
B. Alzheimer disease only
C. Frontotemporal dementia

Correct Answer: A
Early visual hallucinations, fluctuating cognition and spontaneous parkinsonism strongly suggest dementia with Lewy bodies.

What is the most important initial approach to delirium in an older adult?
A. Identify and treat the underlying cause while providing supportive care
B. Start long-term antipsychotics in every patient
C. Use physical restraints routinely
D. Assume irreversible dementia
Correct Answer: A
Delirium is usually secondary to acute illness, medication or physiologic disturbance; treatment focuses on the precipitant and nonpharmacologic support.

An 82-year-old develops acute fluctuating confusion and inattention after surgery. What is the most likely diagnosis?
A. Delirium
B. Dementia
C. Major depression
D. Schizophrenia
Correct Answer: A
Acute onset, fluctuating course and impaired attention are core features of delirium.
Medicine
Critical Care & Sepsis
A patient with severe sepsis requires central venous access. Which practice best reduces catheter-related bloodstream infection?
A. Maximal sterile barrier precautions with chlorhexidine skin antisepsis
B. Routine prophylactic systemic antibiotics for every line
C. Daily line replacement
D. Avoid hand hygiene
Correct Answer: A
Evidence-based central-line bundles emphasize hand hygiene, maximal sterile barriers, chlorhexidine skin preparation and daily review of line necessity.

A patient with organophosphate poisoning has salivation, lacrimation, bronchorrhea and bradycardia. Which antidotal regimen is appropriate?
A. Atropine plus pralidoxime
B. Naloxone plus bicarbonate
C. Vitamin K only
D. Methylene blue only
Correct Answer: A
Atropine treats muscarinic toxicity while pralidoxime reactivates acetylcholinesterase if given appropriately.

A patient with opioid overdose is comatose with respiratory depression and pinpoint pupils. Which antidote is indicated?
A. Naloxone
B. Flumazenil
C. Atropine
D. Pralidoxime

Medicine
Critical Care & Sepsis
A patient develops pulseless electrical activity. Which reversible cause should be actively sought during CPR?
A. Tension pneumothorax
B. Stable hypertension
C. Chronic eczema
D. Cataract
Correct Answer: A
Resuscitation requires identification of reversible causes of PEA such as hypoxia, hypovolemia, tension pneumothorax, tamponade, toxins and thrombosis.
