A patient has just returned from the cath lab. She had an
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



angioplasty for occlusion of her RCA. She still has femoral artery
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



and vein sheaths in place. The patient complains of chest pain
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



that she rates 9/10 about an hour after she returns from the cath
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



lab. Which of the following is indicated?
i,- i,- i,- i,- i,- i,-




i,- A. Administer morphine IV.
i,- i,- i,-




i,- B. Administer nitroglycerin sublingual spray.

i,- D. Notify the physician

New-onset severe chest pain after percutaneous coronary i,- i,- i,- i,- i,- i,- i,-



intervention suggests acute closure of the dilated coronary artery.
i,- i,- i,- i,- i,- i,- i,- i,- i,-



The patient needs to be returned to the cardiac catheterization
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



laboratory for repeat dilation and probable insertion of stent.

A 35-year-old woman underwent a mitral valve replacement. Her
i,- i,- i,- i,- i,- i,- i,- i,- i,-



chest tube output has been approximately 125 mL/hr for the last
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



3 hours, and now the drainage has ceased suddenly. The
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



immediate assessment reveals a significant decrease in BP, RAP
i,- i,- i,- i,- i,- i,- i,- i,- i,-

,12, PAP 30/15 , PAOP 13. What other data would indicate the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



development of cardiac tamponade? i,- i,- i,-




A. Increased venous oxygen saturation (SvO2)
i,- i,- i,- i,- i,-




B. Decreased UO
i,- i,-




C. Muffled heart sounds
i,- i,- i,-




D. New holosystolic murmur at the sternum
i,- i,- i,- i,- i,- i,- i,-i,- i,- C
Muffled heart sounds are a classic finding in cardiac tamponade.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



Remember the classic indications of cardiac tamponade referred i,- i,- i,- i,- i,- i,- i,- i,-



to as Beck's triad: muffled heart sounds, jugular venous
i,- i,- i,- i,- i,- i,- i,- i,- i,-



distention, and hypotension. Even though urine output is a i,- i,- i,- i,- i,- i,- i,- i,- i,-



sensitive indicator of cardiac output and in cardiac tamponade a
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



decreased stroke volume results in a decreased cardiac output, by
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



the time a nurse would notice the decreased urine output, the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



patient may have already had a cardiopulmonary arrest. The SvO2
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



actually would decrease because of the decrease in cardiac
i,- i,- i,- i,- i,- i,- i,- i,- i,-



output. New holosystolic murmur at the lower left sternal border
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



is a sign of ventricular septal rupture.
i,- i,- i,- i,- i,- i,-




A patient has had an inferior MI. He now has a new holosystolic
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



murmur at apex, acute severe dyspnea, decreased cardiac index,
i,- i,- i,- i,- i,- i,- i,- i,- i,-



and a normal cardiac silhouette on x-ray. Which of the following
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



complications most likely is occurring in this patient? i,- i,- i,- i,- i,- i,- i,-

,A. Acute mitral regurgitation
i,- i,- i,-




B. Rupture of left ventricular free wall
i,- i,- i,- i,- i,- i,-




C. Ventricular septal rupture
i,- i,- i,-




D. Acute aortic stenosis
i,- i,- i,- i,-i,- i,- A
With an inferior MI, the risk of the papillary muscles being
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



affected is greater. The papillary muscles of the LV maintain
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



normal mitral valve fxn. If damaged, acute mitral regurgitation
i,- i,- i,- i,- i,- i,- i,- i,- i,-



occurs and is manifested by a new holosystolic murmur at the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



apex, acute pulmonary edema, and decreased cardiac
i,- i,- i,- i,- i,- i,- i,-



output/index


A patient in the ED with complaints of chest pain. The 12-lead
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



EKG shows ST elevation in leads V3 and V4. Occlusion of the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



affected coronary artery most likely would affect perfusion to
i,- i,- i,- i,- i,- i,- i,- i,- i,-



which portion of the conduction system?
i,- i,- i,- i,- i,-




A. Sinoatrial (SA) node
i,- i,- i,-

i,-




B. Murmur that increases with squatting

i,- i,- i,- i,-i,- i,- *B
Classic manifestations of hypertrophic cardiomyopathy are chest
i,- i,- i,- i,- i,- i,- i,-



pain, syncope, and an aortic stenosis type of murmur that
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



decreases when the patient is in a squatting position. The first
