Question | Answer |
---|---|
Seizures | keep suction at bedside |
Status epilepticus | repeated seizures over 30 minutes |
Tx for occurring seizure | Phenobarb, Valium, Dilantin |
Alzheimer's | look at reaction to changing environment, follow the same schedule |
Huntington's | jerky hand movements are common sign |
Parkinson's | no production of dopamine, dopamine= voluntary movement |
Parkinson's treatment | Sinemet (watch for dyskinesias) |
Spinal Cord Injury | impaired physical mobility is safety issue |
Spinal Cord Injury in ED | Airway first |
MS treatment | treated with Medrol |
Gullian-Barre | patient needs to be intubated |
Plasmaphoresis | removal of circulating antibodies (used in tx of GBS) |
Trigeminal neuralgia | excruciating pain in face, provide least amount of sensation to face, chew on unaffected side |
Cerebrum trauma | causes memory loss |
Frontal lobe injury | causes impaired judgment |
hypoactive DTR | assist with walking b/c pt can't feel legs |
Decorticate | hands in towards core |
Pt has insulin pump and needs MRI | Cancel MRI |
Lumbar Puncture at risk for complications | watch for restlessness/ agitation in patient before procedure |
Lumbar Puncture results | should be crystal clear |
Assessment after cardiac cath | pulses below site |
U wave | shows electrolyte imbalance |
Cardiac Output | amount of blood pumped from Left ventricle in one minute |
Chest pain r/o MI | look at Troponins (T and I) |
P waves | atrial depol |
PR interval | 0.12-0.2 |
Complete heart block (3rd degree) | pt needs external pacing |
Left sided HF | dyspnea (and other respiratory symptoms) |
Right sided HF | JVD, edema |
Lasix | watch for K, K wasting (normal K is 3.5-5) |
diruetics | look for serum K, it's potassium wasting |
Prosthetic Heart Valve | watch for blood clots, form easily on prosthetics |
Cardiac Tamponade Tx | pericaradiocentesis is needed to drain fluid |
Cardiac dysrhythmia | heart cannot pump oxygen to organs and tissues |
V Fibb | Defibb the V Fibb, electrical chaos in ventricles |
Arterial insufficiency | causes pain |
Care after cardiac cath | keep leg straight, look for hematoma |
Arteriosclerosis | plaque on inside of artery walls |
Atherosclerosis | hardening of artery |
Sinus Tachy | greater than 100 bpm, it has a normal PQRS it's just fast |
Interpreting Strips | Determine HR, P wave presence, PR interval, Interpret rhythm |
Adenosin | brief asystole, used to stimulate regular heart rhythm |
Run of V Tach | fatal rhythm, do ABCs and then shock |
Buergers | no tobacco or nicotine |
MI symptoms in women | usually asymptomatic, have indigestion or back pain |
Beta Blockers | increase contractility of heart, increase cardiac output |
MAP | needs to be greater than 60 for adequate tissue perfusion |
PAD | characterized by intermittent claudation |
6 Ps of arterial insufficiency | Pain, parathesias, paralysis, pallor, pulselessness, and poikilothermia (can't maintain constant core body temp) |
Strip reading (A Fibb) | no P wave, wiggly line on EKG where P wave should be |
Strip reading- paroxysmal SVT | happens for short period of time, ventricles firing rapidly, ablation is done if meds don't work |
Strip reading- Bigeminy | PVCs every other beat |
Hypertrophy and hyperplasia | normal for cells |
Estrogen | promotes growth of cancer in female reproductive system |
Testosterone | promotes growth of cancer in male reproductive system |
G1 | well differentiated |
G4 | poorly differentiated |
Cancers that are left untreated can cause | reduced immunity and blood producing functions, altered GI structure and function, motor and sensory deficits, decreased resp function |
Palliative surgery | doesn't cure, just relieves symptoms |
Purpose of radiation | kill cancer cells with limited exposure/effects on normal cells |
S/E of radiation | fatigue, local/permanent hair loss, altered taste sensation, tissue fibrosis, scars |
Instructions for pts with radiation | don't expose area to sun for 1 year, provide objective and accurate information, don't remove ink markings until radiation is complete |
Important intervention for cancer patients | mouth care to prevent mucositis |
Major complication of chemo | extravasation |
tumor lysis syndrome | cancer cells killed so quickly that their waste products build up in the blood |
Greatest risk factor for cancer | Age |
Patients that need to be further evaluated for cancer | Patients with mouth sores that won't heal (think CAUTION) |
Environmental factors | cause damage to cells and cause damaged cells to replicate |
Breast cancer | most common neoplasm in women |
neoplasm | abnormal growth of body tissue (think endometriosis and fibroids) |
benign tumor cells | don't migrate, have small nuclear to cytoplasm ratio, orderly |
cancer cells | have wrong number of chromosomes (aneuploidy), large nucleus to cytoplasm ratio, spread, loosely associated, don't look like parent cells (anaplasia) |
Meds to give before chemo | Compazine, Zofran |
Initiation | changes in cells resulting from intense and prolonged exposure to an external agent |
Metastsized cancer | same kind of cancer as where it originated from |
SVC syndrome | improved if swelling in hands has gone down (also if swelling in face goes down) |
Mouth care for cancer patients | no alcohol based mouth wash, soft-bristled tooth brush, drink lots |
antimetabolites | interferes with metabolism of cancer cells |
antimitotics | interferes with cell division |
antitumor | damages DNA |
vesicant | damages skin, destroys tissues |
Main cause of SIADH | lung cancer |
Tx in dying patients- pain | prevent pain, give morphine |
Pt with death rattle intervention | turn them on their side |
dying patient is dyspnea | give morphine |
Don't talk about this in front of dying patient's family | religion |
