Bbc 7: Practice Questions E

Front 1

What is the most common cardiac outcome to severe hyperkalemia?

Back 1

Ventricular vibrillation or asystole

both can lead to syncope

Front 2

Acute onset high fever (pyrexia), chills and a new onset cardiac murmur?

Back 2

Acute infective endocarditis

Often the right heart (tricuspid valvue)

Front 3

Valves that are most common to have pre-existing pathologies?

Back 3

Left side heart valves: mitral and aortic

Front 4

Sudden, tearing chest pain radiating to the back is a classic finding of

Back 4

aortic dissection

Front 5

A 34-year old construction worker complained of sudden, tearing chest pain that radiated to his back. He was unconscious by the time medics arrived. At presentation to the hospital, he is found to have a BP of 70/40. Physical exam reveals jugular venous distention and distant heart sounds. What accounts for the findings on physical exam?

Back 5

Cardiac tamponade

Front 6

The most common complication overall, and the most common within the first 24 hours of an MI is

Back 6

arrhythmia

Front 7

Just read about cardiac tamponade

Back 7

tamponade is the outward compression of the heart causing collapse of chambers. When that happens, cardiac output ceases or is significantly diminished, resulting in loss of consciousness (due to inadequate perfusion to brain), distant heart sounds (because the heart is enveloped in a sac of blood), and jugular venous distention (JVD), due to back-up of blood in the venous structures (since blood is not adequately being pumped through the heart).

Front 8

Classic triad of aortic stenosis?

What increases the sound of the murmur?

Back 8

Dyspnea, angina and syncope

Passive leg raising increases the sound of aortic stenosis. Anything that would increase preload!

Front 9

Expiration increases which heart sounds?

Back 9

aortic regurgitation, MVP and HCOM

Front 10

Sudden squating increases the sounds of

Back 10

aortic regurtitation and mitral regurgtitation
