EKG
This rhythm serves as the normal baseline for cardiac conduction, characterized by a regular rate of 60–100 bpm and a clear P wave preceding every narrow QRS complex
Normal Sinus Rhythm
What is the first medication given during a code?
epinephrine
What causes a rise in lactate during septic shock?
anaerobic metabolism
What procedure restores blood flow to the heart muscle by using blood vessels from another part of the body to create a graft and circumnavigate 1 or more coronary artery blockages?
CABG
How many organs need to be failing to be considered MODS?
2+
"irregularly irregular" supraventricular rhythm lacks distinct P waves and places patients at a high risk for ischemic stroke due to atrial blood stasis.
A-fib
What medication is given for angina?
Nitroglycerin
How many ml/kg of crystalloid do we give over a 3 hour period when a patient is septic?
30ml/kg
At how many mm does an abdominal aortic aneurysm require urgent treatment?
55mm
This is what we call a stiffened valve due to calcification. This leads to a narrowing that obstructs forward flow of blood.
Stenosis
Originating in the lower chambers, this lethal rhythm appears on a telemetry monitor as wide, rapid, QRS complexes without visible P waves.
V-Tach
What medication is given when a patient is in SVT to try to reset and slow down the heart?
adenosine
Name the 4 types of Distributive Shock
Septic, Anaphylactic, Toxic, Neurogenic
Name The three components of Beck's Triad in Cardiac Tamponade
Hypotension, JVD, Muffled Heart Sounds
When troponins are elevated, but EKG does not show ST Elevation
NSTEMI
Often triggered by a prolonged QT interval or severe hypomagnesemia, this specific polymorphic variant of V-Tach features QRS complexes that appear to "twist" around the isoelectric baseline.
Torsades de Pointes
What is the first line medication given when fluid resuscitation isn't increasing the BP to a satisfactory MAP?
What are the 4 Stages of Shock?
Initial, Compensatory, Progressive, Refractory
Backflow of blood into the left atrium increases preload and left ventricle workload eventually causing left ventricle dilation to maintain cardiac output.
Mitral Valve Regurgitation
What labs would the nurse trend if the pt has confirmed or suspected DIC? These tests make up the ISTH score.
PT/INR, Fibrinogen, D-Dimer, Platelets
Unlike it's counterpart which features a progressively lengthening PR interval before a dropped QRS, this second-degree AV block displays consistent PR intervals followed by intermittent unpredictable dropped QRS complexes without warning.
Mobitz Type II (Second Degree AV Block Type 2)
During a code, what is the first dose of amiodarone given?
300mg
What are the 4 SIRS criteria?
Temp <36 or >38C, HR > 90/min, Resp >20/min or PaCO2 <32, WBC <4000 or >12000 or >10% Bands
This Coronary Artery is referred to as the "widow maker" due to an increased risk of mortality if a blockage occurs in this specific coronary artery.
Left Anterior Descending (LAD)
What is a normal CVP?
8-12 mmHg
