Flashcards in drowning Deck (21):
Because respiratory arrest is the most common cause of cardiac arrest in drowning victims, _______ approach should be used for drowning victims
the traditional A-B-C
instead of the AHA’s new C-A-B approach
Cardiac arrest from drowning - arrythmia??
The initial rhythm in the arrest is PEA followed by asystole.
abx in drowning
no evidence that empiric prophylactic treatment with antibiotics is efficacious for pulm or cns infection
MONA is for?
(Morphine, Oxygen, Nitroglycerin, Aspirin) greets chest pain patients at the door
Relative contraindications to the use of β-blockers include
The most common ECG abnormalities in PE are
tachycardia and nonspecific ST-T– wave abnormalities
S1Q3T3 pattern is seen in
“right heart strain pattern”- manifestation of acute pressure and volume overload of the right ventricle
S1Q3T3 is a sign of acute cor pulmonale
lead I S wave= complete/ incomplete RBBB
lead III= Q wave, slight ST elevation, and an inverted T wave*
*These findings are due to the pressure and volume overload over the right ventricle which causes repolarization abnormalities.
The main ED treatment for atrial fibrillation is _________
rate control- agent most commonly used= diltiazem
If the patient is in atrial fibrillation for greater than 48 hours, then needs to be ____________ prior to cardioversion.
stable atrial fibrillation --> echocardiogram
clot= Coumadin 2-3 wks w/ cardioversion when INR therapeutic.
no clot= heparin and cardioversion
ECG manifestations of hypokalemia include
flattening of T waves, ST-segment depression, and U waves.
_____________ must be avoided until PTX completely resolves
Air travel and underwater diving (changes in atmospheric pressure)
what drug do you never use in cocaine coronary vasospasm
leaves alpha overwhelmed, makes things worse
Lorazepam is a great choice instead
Inferior wall MIs are characterized by ST elevation in at least two of the inferior leads __________
II, III, aVF
Neuroleptic malignant syndrome (NMS) is an idiosyncratic, life-threatening reaction to antipsychotic medications, with ___________ being the most common cause.
any patients with temperatures greater than ____ most likely have non-infectious etiologies for temperature elevation.
Dystonic reactions tpo anti-psych should be treated with____________
IM or IV
-benztropine (Cogentin®)- 1 to 2 mg
-diphenhydramine (Benadryl®)- 25 to 50 mg
Potential side effects of haloperidol include
acute dystonia, prolonged QT interval, Parkinsonism, and akathisia
The following mnemonic can be used to recall the common causes of an increased anion gap metabolic acidosis: CAT MUDPILES
C - cyanide
A - alcoholic ketoacidosis
T - toluene
M - methanol
U - uremia
D - diabetic ketoacidosis
P - paraldehyde
I - isoniazid/iron
L - lactate
E - ethylene glycol
S - salicylates
__________ is the most effective and most
rapid means of reducing preload in a patient with CHF.
