What is peripheral neuropathy?
A group of conditions in which the nerves leaving the spinal cord are damaged. The signals moving to or from the brain become distorted. Can be caused by metabolic disorders, trauma, toxins, tumors and autoimmune disorders. Patient will have sensory and motor impairment, loss of sensation, numbness, burning pain, and will eventually lose the ability to feel their feet in some areas. Caused by high blood glucose.
239
What is glucopenia?
A shortage of glucose in the brain (hypoglycemia)
240
What are the three primary buffer systems for the body to maintain ph?
Circulating bicarbonate buffer system
Respiratory system
Renal system
241
What value do you need in order to say someone is in a metabolic disorder vs. a respiratory acid-base disorder?
Must have a bicarbonate value to determine if it is metabolic acidosis vs metabolic alkalosis. Normal bicarb is 23 to 30. If bicarb is above 30, the patient is in metabolic acidosis. If bicarb is below 23, the patient is in metabolic alkalosis.
242
What is pectoriloquy?
The sound of words heard through the chest wall with auscultation. Indicates a cavity or consolidation of lung tissue.
243
What is cystitis?
Inflammation of the urinary bladder. Often caused by infection and is usually accompanied by frequent, painful urination. Will present with possible blood in the urine, cloudy or strong smelling urine.

247
How would you confirm a posterior STEMI?
Look for ST depression in v1 and v2, confirm with reciprocal changes in v7, v8, v9 (would show ST elevation)
248
What is scarbossa's criteria?
Set of findings used to identify an MI in the presence of LBBB or ventricular paced rhythm.
- concordant ST elevation greater than 1 mm in leads with a positive QRS complex (score 5)
- concordant ST depression greater than 1 mm in v1-v3 (score 3)
- excessively discordant ST elevation greater than 5 mm in leads with a -ve QRS complex (score 2)
* a total score greater than or equal to 3 is 90% accurate for diagnosing MI
249
What is the difference between libel and slander?
Libel and slander are both considered defamation, which is when someone's words end up causing harm to your reputation or your livelihood.
Libel - written or published defamation
Slander- spoken defamation

Symptomatic patient with possible ST depression and T wave inversion but no ST elevation. Essentially a pre STEMI
259
What should each intubation attempt be limited to?
30 seconds
260
What is autonomic dysreflexia?
A potentially dangerous complication of a spinal cord injury where an individual's blood pressure will spike to dangerous levels in an undetermined period of time after the initial injury because of a minor insult or stimulation. Also called spinal hyperreflexia
261
What cells release glucagon in the pancreas?
Alpha cells
262
What cells release insulin in the pancreas?
Beta cells
263
What do the delta cells in the pancreas release?
Somatostatin
264
A hypoglycemic patient needs?
Glucagon or glucose. Glucagon converts glycogen to glucose
265
A hyperglycemic patient needs?
Insulin
266
What is the most narrow portion of the airway in a child?
Below the glottis at the level of the cricoid cartilage
267
What is the most narrow portion of the adult airway?
Level of vocal cords
268
What is a late sign of septic shock?
Low temp
269
Is neurogenic shock only trauma related?
No, comes with any disruption of blood flow
270
Describe a black widow spider bite presentation and tx
Immediate localized bite from a spider with a red hour glass on the thorax.
Progressive muscle spasms of all large muscle groups is the key sign, usually stomach muscles and thigh. Other signs and symptoms are nausea and vomiting, decreased LOC, seizures, and paralysis.
Tx= IV muscle relaxants for muscle spasms, Valium, calcium gluconate @ 0.1-0.2 mg/kg of 10% solution, antivenom if available.
271
Describe a brown recluse spider bite presentation and tx
Painless, small erythematosus macule surrounded by a white ring around site
Patient will present with chills, fever, nausea, vomiting, joint pain, localized redness and swelling and pain around 8 hours after bite. Tissue necrosis will begin days to weeks after bite.
Venom causes tissue necrosis so tx is surgical debridement
272
Describe the presentation and tx of a coral snake bite
Patient will present with localized numbness and weakness, drowsiness, ataxia (impaired balance), slurred speech, salvation, paralysis of tongue, drooping of eyelids, double vision, DILATED PUPILS, abdominal pain, nausea, vomiting, loss of consciousness, seizures, hypotension, respiratory failure.
Venom is a neurotoxin
*tx is DO NOT let the patient move. The more you move, the faster the venom spreads. Put a light constricting band (lymphatic constriction only) proximal to the bite and tx associated ABC needs
273
What is the presentation and tx for a jellyfish sting?
Intense local pain and swelling, weakness, nausea and vomiting, dyspnea, tachycardia, hypotension or severe shock
Tx= establish and maintain airway, apply light constricting band for lymphatic flow only, apply heat or hot water, remove any stingers
*venom is designed to interact with other marine animals/ oceans are cold so the venom is designed to operate at a cooler temp. Heat the area to disable the venom
274
What nerve controls the diaphragm?
Phrenic nerve
275
Describe electrical alternans and what it is associated with
Electrical alternans occurs because there is an effusion of fluid around the pericardium that blankets the electrical activity of the heart.
The electrical amplitude therefor alternates between strong/weak/strong/weak etc on an ECG
associated with pericarditis and may be accompanied by atrial arrhythmias
276
Describe the renin/angiotensin system in its entirety
This system is designed to keep blood pressure up ultimately.
Kidneys secrete renin = angiotensinogen now converts to angiotensin 1 = lungs secrete ACE (angiotensin converting enzyme) which converts angiotensin 1 to 2 = angiotensin 2 causes vasoconstriction and secretion of aldosterone from adrenals = causes body to retain water, thus increasing BP
277
What type of bleed is a subdural hematoma?
Venous bleed
278
What type of bleed is an epidural hematoma?
Arterial bleed
279
What is key to remember when deciding if a person is in a metabolic acid/base disorder?
Need a sodium bicarb value to diagnose metabolic acidosis or alkalosis. Bicarb will follow ph up or down.
280
What releases follicle stimulating hormone?
Pituitary gland
281
What releases LH?
Pituitary gland
282
What is the Graafian follicle?
Sac that the egg is in, secretes estrogen
283
What secretes progesterone?
Corpus luteum
284
Describe the entire sequence of blood flow through the heart and body
1. ) blood that has circulated through the body, which has lost all its oxygen and has picked up carbon dioxide, enters through the vena cava to the right atrium.
2. ) right atrium pumps blood through tricuspid valve into right ventricle.
3. ) right ventricle pumps blood through the pulmonary artery to the lungs to be oxygenated.
4. ) oxygenated blood returns via pulmonary vein into the left atrium
5. ) oxygenated blood pumps through the mitral valve and into the left ventricle
6. ) the left side of the heart contracts and pumps blood through the aortic arch on its way to all parts of the body. At this point, there are a few options for where blood flow can be pumped...
- carotid artery to the brain
- auxiliary arteries to the arms
- through the aorta and into the torso and legs
7. ) blood will then move through the arteries, then through the capillaries, and then return through the veins.
8. ) deoxygenated blood returns to the heart and the cycle repeats
