Correct Answer: Jerky facial movements

Tardive dyskinesia causes irregular, involuntary jerky movements of the face and distal extremities from chronic antipsychotic use.
Option a is incorrect because muscle rigidity characterizes acute dystonia or parkinsonism, not tardive dyskinesia.
Option b is incorrect because resting tremor suggests parkinsonism, not the involuntary movements of tardive dyskinesia.
Option d is incorrect because bradykinesia means slowed movement, opposite of tardive dyskinesia's involuntary movements.

Correct Answer: Allodynia

Allodynia describes pain from stimuli that normally don't cause pain, characteristic of neuropathic pain conditions.
Option a is incorrect because hyperalgesia means increased pain from painful stimuli, not pain from non-painful stimuli.
Option c is incorrect because dysesthesia refers to unpleasant abnormal sensations, not specifically pain from normal touch.
Option d is incorrect because paresthesia describes pins and needles sensations, not pain from non-painful stimuli.

Correct Answer: Entire colon

Extensive colonic involvement or pancolitis that fails medical management often requires surgical colectomy for ulcerative colitis.
Option a is incorrect because isolated rectal involvement usually responds to medical therapy without surgery.
Option b is incorrect because left-sided colitis can often be managed medically without surgical intervention.
Option d is incorrect because ulcerative colitis doesn't affect small intestine; this would suggest Crohn's disease.

Correct Answer: Vitamin B12

Vitamin B12 deficiency causes reversible cerebellar ataxia through demyelination that improves with proper supplementation therapy.
Option a is incorrect because vitamin A deficiency affects vision and immunity, not cerebellar function causing ataxia.
Option c is incorrect because vitamin C deficiency causes scurvy with bleeding, not neurological ataxia symptoms.
Option d is incorrect because vitamin D affects bones and calcium metabolism, not cerebellar coordination.

Correct Answer: MMR vaccine

MMR contains live attenuated viruses absolutely contraindicated during pregnancy due to theoretical fetal infection risks.
Option a is incorrect because influenza vaccine uses inactivated virus safe and recommended during pregnancy.
Option c is incorrect because Tdap is specifically recommended between twenty-seven and thirty-six weeks of pregnancy.
Option d is incorrect because hepatitis B vaccine is safe during pregnancy for at-risk mothers.

Correct Answer: Thoracentesis

Thoracentesis uses needle drainage to remove blood from pleural space, allowing lung re-expansion in hemothorax.
Option a is incorrect because bronchoscopy examines airways internally but doesn't drain pleural space blood.
Option c is incorrect because intubation provides airway access for ventilation, not pleural blood drainage.
Option d is incorrect because tracheostomy creates surgical airway but doesn't address pleural space blood.

Correct Answer: Parafollicular cells

Medullary thyroid cancer originates from parafollicular C cells that produce calcitonin, distinguishing it from other thyroid cancers.
Option a is incorrect because follicular cells give rise to papillary and follicular thyroid cancers, not medullary.
Option c is incorrect because epithelial cells is too general; specific parafollicular cells cause medullary cancer.
Option d is incorrect because lymphoid cells cause thyroid lymphoma, not medullary thyroid carcinoma.

Correct Answer: TENS unit

Transcutaneous electrical nerve stimulation delivers low-voltage electrical current through skin, effectively relieving chronic joint pain.
Option a is incorrect because acupuncture uses needles at specific points, not electrical current for pain relief.
Option c is incorrect because massage therapy uses manual manipulation, not electrical stimulation for pain management.
Option d is incorrect because heat therapy uses temperature, not electrical current to relieve joint pain.

Correct Answer: Intermediate action

Lorazepam's intermediate half-life provides effective acute anxiety relief without excessive accumulation or frequent dosing requirements.
Option a is incorrect because longest half-life medications risk accumulation; intermediate duration is preferable for acute use.
Option c is incorrect because while true, the intermediate action is more relevant for acute anxiety management.
Option d is incorrect because lorazepam has moderate to high potency, not the weakest among benzodiazepines.

Correct Answer: After observation period

Amoxicillin starts after forty-eight to seventy-two hour observation period if symptoms persist, indicating bacterial infection.
Option a is incorrect because immediate antibiotics prevent distinguishing viral from bacterial infections, promoting resistance.
Option c is incorrect because one week delay risks complications if bacterial infection requires earlier treatment.
Option d is incorrect because two weeks far exceeds appropriate observation period for pediatric ear infections.

Correct Answer: Thirteen years

Progeria patients typically live to thirteen years average, with death usually from cardiovascular complications of accelerated aging.
Option a is incorrect because five years underestimates survival; most children live into their teenage years.
Option c is incorrect because twenty-five years significantly exceeds typical progeria life expectancy.
Option d is incorrect because forty years far exceeds progeria survival, as most die in teenage years.

Correct Answer: Sulfa drugs

Sulfa drugs trigger oxidative stress causing severe hemolytic crisis in G6PD deficiency requiring strict avoidance.
Option a is incorrect because beta blockers don't cause oxidative stress triggering hemolysis in G6PD deficiency.
Option b is incorrect because ACE inhibitors are safe in G6PD deficiency without hemolytic risk.
Option d is incorrect because calcium channel blockers don't trigger the oxidative stress causing hemolysis.

Correct Answer: Arousal symptoms

Hypervigilance and exaggerated startle represent arousal and reactivity symptoms, one of four PTSD symptom categories.
Option a is incorrect because re-experiencing involves flashbacks and nightmares, not hypervigilance and startle responses.
Option b is incorrect because avoidance symptoms involve avoiding triggers, not the hyperarousal symptoms described.
Option d is incorrect because dissociative symptoms involve detachment and unreality, not hypervigilance responses.

Correct Answer: Prevent reinfection

Simultaneous treatment prevents reinfection cycle between mother's breast and infant's mouth during breastfeeding.
Option a is incorrect because resistance prevention isn't the reason for treating both; it's preventing transmission.
Option c is incorrect because effectiveness doesn't increase with dual treatment; it prevents cross-infection.
Option d is incorrect because treating both doesn't reduce side effects; it prevents reinfection cycles.

Correct Answer: Glenn procedure

Glenn procedure performed at four to six months connects superior vena cava to pulmonary artery directly.
Option a is incorrect because Norwood procedure is first stage enlarging aorta, not the SVC connection.
Option c is incorrect because Fontan procedure is third stage connecting inferior vena cava, not superior.
Option d is incorrect because Ross procedure involves different cardiac surgery, not hypoplastic left heart staging.

Correct Answer: Two weeks

Major depression diagnosis requires symptoms persisting at least two weeks, distinguishing it from transient adjustment reactions.
Option a is incorrect because one week is insufficient to diagnose major depression versus situational sadness.
Option c is incorrect because one month exceeds the minimum two-week requirement for depression diagnosis.
Option d is incorrect because two months far exceeds the diagnostic threshold of two weeks duration.

Correct Answer: Alveolar walls

Emphysema involves alveolar wall destruction reducing surface area for gas exchange, distinguishing it from chronic bronchitis.
Option a is incorrect because bronchial wall inflammation characterizes chronic bronchitis, not emphysema's alveolar damage.
Option c is incorrect because tracheal rings remain intact in COPD; damage occurs at alveolar level.
Option d is incorrect because pleural lining damage causes different conditions, not emphysema's parenchymal destruction.

Correct Answer: Fruity scent

Fruity breath odor results from acetone production during ketogenesis when cells metabolize fat for energy.
Option a is incorrect because ammonia smell suggests kidney disease with urea buildup, not diabetic ketoacidosis.
Option c is incorrect because metallic taste occurs with various conditions but isn't characteristic of DKA.
Option d is incorrect because garlic odor suggests other metabolic conditions, not the ketone production of DKA.

Correct Answer: Ulcerative colitis

Perinuclear anti-neutrophil cytoplasmic antibodies specifically associate with ulcerative colitis over other inflammatory bowel diseases.
Option a is incorrect because Crohn's disease typically shows ASCA antibodies, not pANCA positivity.
Option c is incorrect because celiac disease involves different antibodies like tissue transglutaminase, not pANCA.
Option d is incorrect because irritable bowel syndrome doesn't involve antibodies; it's functional, not inflammatory.

Correct Answer: SIADH

Syndrome of inappropriate antidiuretic hormone causes water retention and hyponatremia, common in small cell lung cancer.
Option a is incorrect because Cushing syndrome involves cortisol excess, not the water retention causing hyponatremia.
Option c is incorrect because carcinoid syndrome causes flushing and diarrhea, not water retention with hyponatremia.
Option d is incorrect because Lambert-Eaton syndrome affects neuromuscular transmission, not fluid and electrolyte balance.
