Whicis the Moh of the Following St Common Symptom of Myocardial Infarction?

...

atrial contraction or systemic hy can result is a fourth heart sound. Aortic pertension

valve malfunction is heard as a murm ur.

21. After an anterior wall

mng problemyocardial infarction, whics is indicated by ah of the followiuscultation of

crackles in the lungs?

a. Left-sided heart failure

b. Pulmonic valve malfunction

c. Right-sided heart failure

d. Tricuspid valve malfunction

The left ventricle is responsible for the most of the cardiac output. An anterior wall MI

may result in a decrease in left ventricular function. When the left ventricle doesn’t

function prheart failure, fluid accumulates in the operly, resulting in left-sided

interstitial and alveolar spaces in the lungs and causes crackles. Pulmonic and

tricuspid valve malfunction causes right-sided heart failure.

22. Whics is most commh of the following diaonly used to determgnostic tooline the

location of myocardial damage?

a. Cardiac catheterization

b. Cardiac enzymes

c. Echocardiogram

d. Electrocardiogram

The Emost widely used tool to determine the CG is the quickest, most accurate, and

location of myocarzymes are used to diagnose MI but can’t dial infarction. Cardiac en

23. What is the first intervention for a client experiencing myocardial infarction?

a. Administer morphine

b. Ad minister oxygen

c. Administer sublingual nitroglycerin

d. Obtain an electrocardiogram

24. What is the monse to a myocardial infarction client who ost appropriate nursing resp

is fearful of dying?

a. "Tell me ab out your feeling right now."

b. "When the doctor arrives, everything will be fine."

c. "This is a bad situation, but you'll feel better soon."

d. "Please be assured we'ng we can to make you feel better." re doing everythi

Validation of the client’s feelings is the most appropriate response. It gives the client a

feeling of comfee responses give the client false hope. No ort and safety. The other thr

one can determine if a client experiencing MI will feel or get better and therefore,

these responses are inappropriat e.

25. Whictions protects the ischemh of the following classes of mic myocardiume by dica

blocking catecholamines and sympathetic nerve stimulation?

a. Beta-adrenergic blockers

b. Calcium channel blockers

c. Narcotics

d. Nitrates

Beta-adrenbeta receptors in the myocardium,ergic blockers work by reducing blocking

the responshetic nerve stimulation. They protect the e to catecholamines and sympat

26. What is the most common complication of a myocardial infarction?

a. Cardiogenic shock
