Quick Cardio Review Questions Flashcards
Low Voltage and bradycardia on EKA
findings of hypothyroidis
this med can cause digoxin toxicity by causing hypokalemia
furosimide
after taking cocaine your patient has increase BP and you tx with a beta blocker what does this do
increase the BP, so monitor his BP
A boy has long QT, what things can cause tornado des points (ventricular tachycardia) and/or other ventricular arrhythmias?
-sympathetic stimulation by argument or exertion
increased JVP and dilated veins in the upper extremities
-superior vena cava syndrome
medication that activates plasminogen
-thrombolytics, the plasmin disolves the fibrin in a thrombus in a clot
left ventricular non compliance in HOCM causes what?
-this stiffness of the ventricle causes the mean left atrial pressure that is transmitted back to the lungs causing dyspnea
diabetes is a increased risk factor for women over men
true, this eliminates the premenstral cardiacprotection
best test for cardiac tamponade
transesophageal echocardiography
best test for aortic dissection
CT
echo findings for cardiac tamponage
-collapse of the right atrium or right ventricle
Kussmaul sign is seen when
-constrictive carditis
Paradoxical pulse
-cardiac tamponade
Cardiac patient with no sx, or sx of fatigue, palpitations, chest pain, anxiety, migraines.
-mitral valve prolapse
Older kids or adults with this cardiac condition have high blood pressure, otherwise may have no sx at all because the condition is less severe.
-coarctation of the aorta
Sx of syncope, shortness of breath, chest pain and cyanosis?
-pulmonary HTN (can be seen when a VSD is not recognized early in life and progresses)
Shortness of breath (esp with exertion or when you lie down), fatigue, lightheadedness, nocturnal cough, palpitations, swollen feet or ankles, and excessive urination.
-mitral valve regurgitation
You start a HTN patient on an ACEI or on spironolactone. What lab test do you have to order? Why?
K+, potassium
because ACEI and spironolactone cause hyperkalemia
What would be the symptoms of hyperkalemia on the HTN patient that was caused by the ACEI or spironolactone (potassium sparing agent) medication that you placed them on.
- weakness
- flaccid paralysis
- confused
With tx of CHF often times ACEI and spironolactone are used together in therapy. So of course this combination can lead to hyperkalemia. What are the EKG sx of hyperkalemia?
the stages of EKG changes in hyperkalemia are
first, peaked T waves second comes, wide QRS third comes, loss of p waves fourth comes, sine wave fifth comes, asystole
What is Tx for Hyperkalemia?
Rapid correction: is only temporary and protects the heart
-Calcium chloride
2nd step Tx by
-**D50 and insulin drives K+ back into cells (this sugar and insulin combination works by insulin binds to K+ as is carries sugar into the cells*
- albuterol inhalation 4x-8x normal dose can help tx - Na bicarbinate IV
What is the long term tx for Hyperkalemia?
-
What do you do when you have evidence of hyperkalemia?
- order an EKG
- repeat labs–make sure you have K+ increase
What is the Slow Correction for hyperkalemia?
- Kaylexalate, have them drink it, it binds with the K+ in the gut and keeps it from being reabsorbed
- Lasix, diuresis
- the last and definitive tx is dialysis
How does one get hypokalemia?
-poor intake
-
