Miosis
Correct Answer: Constricted pupils
• Question
Mydriasis
Correct Answer: Dilated pupils
• Question
Alcohol Poisoning s/sx
Correct Answer: Mydriasis pupils, normo BP, increased HR, decreased RR & temp
• Question
Cholinergic
Correct Answer: mimic the activity of the parasympathetic nervous system - aka
parasympathomimetic (releasing/responding to acetylcholine)
• Question
Cholinergic/Narcotic Poisoning
Correct Answer: Miosis pupils
• Question
Amphetamine Poisoning
Correct Answer: Mydriasis pupils, increased HR, RR, BP and temp
• Question
Anticholinergic
Correct Answer: blocks parasympathetic nerve impulses; decreases oral and respiratory
secretions (atropine, Artane)
• Question
The "bends"
Correct Answer: Pain located in the vicinity of articulating joints. Resulting from the
presence of gas bubbles in the blood and tissues common to scuba diving (aka
decompression sickness)
,• Question
TB (active/infectious)
Correct Answer: Chronic cough greater than 2 to 3 weeks, fatigue, weight loss, night
sweats, fevers and chills
• Question
Obstructive Shock
Correct Answer: Obstructive shock is caused by the obstruction of the great vessels of
the heart. The mechanical obstruction leads to impaired filling of the heart with blood.
Any condition that fills the thoracic cavity with fluid, tissue or air can lead to obstructive
shock
• Question
Three of the most common causes of obstructive shock
Correct Answer: Cardiac tamponade, pulmonary embolism, tension pneumothorax
• Question
Gastric lavage
Correct Answer: May be effective for poisoning a that are life threatening. Beneficial for
(1) symptomatic patients who present within one hour of ingestion (2) symptomatic
patients who ingested an agent that slows gastric motility (3) ingestion of sustained
release medications (4) patients who have taken a massive life-threatening amount of a
substance
Routine use is not recommended.
• Question
When does an uncal herniation become life threatening
Correct Answer: An uncal herniation becomes life threatening when a brainstem
compression occurs, or when a hemorrhage occurs
• Question
Brains three divisions
Correct Answer: Cerebellum, brainstem, and cerebrum
• Question
Cerebral cortical areas
Correct Answer: Frontal lobe, temporal lobe, parietal lobe and occipital lobe
,• Question
Bones serve as primary storage for
Correct Answer: Calcium and phosphate
• Question
Group one laryngeal trauma
Correct Answer: Minor airway symptoms with no fractures, simple hematomas, and
small lacerations
• Question
Group 2 laryngeal trauma
Correct Answer: Compromised airway with no cartilage exposure, minor mucosal
disruption, hematoma, swelling or edema
• Question
Group 3 laryngeal trauma
Correct Answer: Compromised airway with exposed cartilage, vocal cord immobility,
mucosal tears, and massive swelling or edema
• Question
Group 4 laryngeal trauma
Correct Answer: Most severe: Compromised airway with exposed cartilage, vocal cord
immobility, mucosal tears and massive swelling or edema. Disruption of anterior larynx,
unstable fractures, two or more fracture lines, or sever mucosal injuries
• Question
Cardiac index of a patient in shock
Correct Answer: <2.5 L/min/m^2
• Question
Normal cardiac index
Correct Answer: 2.5-4 L/min/m^2
• Question
Cardiac index of a Patient with subclinical hypoperfusion
Correct Answer: 2.2-2.5 L/min/m^2
, • Question
Cardiac index of a patient with clinical hypoperfusion
Correct Answer: 2.0-2.2 L/min/m^2
• Question
Calculate mean arterial pressure
Correct Answer: [ (2 x diastolic) + systolic ] divided by 3
• Question
Pylonephritis
Correct Answer: infection of the kidneys
• Question
parasympathetic nervous system
Correct Answer: 'Rest and digest', the division of the autonomic nervous system that
calms the body, conserving its energy
A subdivision of the autonomic nervous system, involved in control of involuntary,
vegetative functions, mediated largely by the vagus nerve through the chemical
acetylcholine.
• Question
increased urine acidity
Correct Answer: indicates bicarb retention
• Question
Renal tubular acidosis
Correct Answer: (RTA) is a medical condition that involves an accumulation of acid in the
body due to a failure of the kidneys to appropriately acidify the urine (alkaline urine,
serum acidosis)
