R ventricular infarction s/s - clear breath sounds, hypotension, JVD.
R ventricular
... [Show More] dilation and dec contractility>> dec preload and CO
Reperfusion therapy standard - Within 60 min of ED arrival
Common causes of PEA - Hypoxia, tension pneumo, cardiac tamponade
BNP as a marker - of L ventricular dysfunction bc ventricles make BNP and an inc of over 100 pg/ml indicates symptomatic HF
Transcutaneous pacing (TCP) - A beat after every pacer spike is electrical capture. Beats are wide complex bc ventricle is paced. Palpate central pulse, pt may still be hypotensive w/ diminished or absent peripheral pulses.
Preferred tx with symptomatic brady esp in pts with acute MI
Wolff Parkinson-White (WPW) syndrome - shortened PR interval and widened QRS complex with a delta wave. When there is an extra electrical conduction path to heart causing electrical signal to arrive too soon at ventricle (pt presents in tachy)
Brugada syndrome - R bundle branch block with ST segment elevation in leads V1-V3 and inc risk of sudden cardiac death (SUDS), common in young men
Wellen syndrome - T wave changes plus history of anginal chest pain w/o serum marker abnormalities, EKG lacks Q waves and significant ST segment elevation. Assoc with critical proximal L anterior descending (LAD) artery stenosis
Hypothermia associations - With bradycardia, Osborne (J) waves and prolonged QT intervals
Sick sinus syndrome - Sinoatrial node (SA) the primary heart pacemaker is not functioning properly resulting in bradydysrythmias and/or tachydysrhythmias with potential for hypotension and syncope
Morphine and nitrates for tx pulmonary edema - Results in dec preload or dec venous return>> dec pulmonary congestion
How to diagnose endocarditis - Echocardiogram
Pericardiocentesis - For suspected pericardial effusion or tamponade
Primary complication of bowel obstruction - Dehydration
Testicular referred pain is indicative of? - Duodenal injury
S/s pancreatitis - Sharp, boring, epigastric pain, inc after eating and having alcohol
Dx with abd CT scan
Paracentesis - Procedure to remove fluid that has accumulated in the abd cavity
After doing paracentesis - Check pt for s/s shock, EKG, dressing, VS q 15 min
Auscultate bowel obstruction - Freq and high pitched
Dec or absent bowel sounds caused by - Paralytic ileus, paralysis, dec in peristalsis
One cause of HYPOkalemia - Excess fluid loss from GI (ex: diarrhea)
One cause of Magnesium depletion - Intestinal malabsorption
Bland diet is for - Peptic and gastric ulcers
Chocolate enhances - S/s GERD
Life threatening complications of acute pancreatitis - Atelectasis, pleural effusion, ARDS
HELLP syndrome - Hemolysis, Elevated liver enzymes, Low platelets)
Liver panel dx it
S/s rhabdomyolysis - HYPERkalemia, brown urine, inc CPK, HYPERcalcemia
Septal hematoma - Can occur with mid facial trauma; untreated can lead to abscess formation or avascular necrosis
Ethmoid bone fx can cause - CSF leakage
Preferred eye irrigation fluid - LR
Pocket vision screener should be held ___ inches from nose? - 14 inches
HHNC s/s - UA shows glycosuria without ketouria, polyuria, tachycardia, hypotension
Acute renal failure (ARF) s/s - HYPERkalemia, HYPOnatremia, HYPOcalcemia, HYPERphosphatemia. K level is priority
BUN / Cr ratio that would dx prerenal failure - > 20:1
S/s HYPOcalcemia - muscle cramping
Latex allergy crossovers - Tomatoes, bananas, kiwis, white potatoes, avocados, bell peppers, peaches
Tx acute HYPERkalemia - Ca and albuterol, sodium bicarb, insulin and dextrose 50%, kayexalate
Kayexalate - Sodium polystyrene sulfonate takes 1-2 hrs to kick in
Herpes zoster (shingles) transmission - Direct contact via vesicular fluid
Fibromyalgia - Chronic fatigue, multiple somatic s/s, widespread pain and hypersensitivity
Thyrotoxic crisis/storm s/s - Hyperthermia, agitation, tachydysrythmias
Scabies tx - Pyrethrin liquid (RID), do 2nd tx 7-10 days later if 1st is done to try hair. If hair is wet, reapply in 24 hrs. Put washable items in plastic bags for 1-2 weeks until mites die
Anterior AND lateral corticospinal tract - Voluntary muscle movement
Lateral spinothalamic tract - Sharp pain and temperature
Posterior tracts - Proprioception, fine touch, 2 pt discrimination
Anterior spinothalamic tract - Crude touch
A fib - Risk factor for embolic stroke
Bell's Palsy cause - Paralysis of CN VIII
C5 > C7 - innervation for arm flexion and extension
L2> L4 - Extension and flexion legs
L4>L5 - Foot flexion and toe extension
S3>S5 - Anal sphincter tone [Show Less]
