A

Q

What is heave or lift?

A

sustained, forceful thrusting of ventricle during systole; occurs with ventricular hypertrophy as a result of increased workload

right ventricular heave seen at STERNAL BORDER
left ventricular heave seen at APEX

28
Q

What are the steps to palpate PMI (Point of maximal impulse)?

A
  1. Use 1 finger pad
  2. Ask patient to exhale and then hold it

  4. Best felt at end of expiration
29
Q

What are some characteristics of the PMI (apical impulse)?

A

Duration: short, only first half of systole

30
Q

What are the steps to palpating the precordium?

A

  2. Gently palpate apex, left sternal border, and base
  3. Normally none occur but if present, note the timing
31
Q

What is a thrill?

A

palpable vibration, signifies turbulent blood flow and directs you to locate the origin of loud murmurs. ABSENCE OF THRILL DOESNT RULE OUT PRESENCE OF A MIRMUR

32
Q

Percussion was replaced by ____ according to EBP

A

chest x-ray and echocardiogram

33
Q

What are the steps for auscultating the precordium?

A

39
Q

Describe the S3 heart sound (ventricular gallop)

A

ABNORMAL in adults, NORMAL in children
indicated decreased compliance of ventricles (heart failure)
heard at apex or lower LSB
LUB DUB TA “kentucky”
follows IMMEDIATELY AFTER S2

40
Q

Describe the S4 heart sound (atrial gallop)

A

ventricular filling sound, occurs when atria contracts late in diastole
HEARD IMMEDIATELY BEFORE S1
heard best at apex with patient in left lateral position
indicates decreased compliance of ventricle (CAD, cardiomyopathy)

A

A: Aspirin Therapy
B: BP Control
C: Cholesterol Control
S: Smoking cessation
Small changes in lifestyle

48
Q

Why is there low cardiac output during heart failure?

A

heart fails as a pump and circulation is backed up, kidney compensatory mechanism of retaining water and sodium causes further congestion

49
Q

Acute Onset Heart Failure

A

as following a myocardial infarction when the hearts contracting ability has been directly damaged

50
Q

Chronic Onset Heart Failure

A

as with hypertension, when the ventricles must pump against chronically increased pressure

51
Q

3 STEPS FOR NECK ASSESSMENT CHECKLIST

A
  1. OBSERVE AND PALPATE CAROTID
  2. OBSERVE JUGULAR VENOUS PULSE
  3. ESTIMATE JUGULAR VENOUS PRESSURE
52
Q

10 STEPS FOR PRECORDIUM ASSESSMENT CHECKLIST

A
  1. Describe location of apical impulse
  2. Note any heave or thrill
  3. Identify anatomic areas where you listen
  4. Note rate and rhythm of heartbeat
  5. Identify S1 and S2 and note any variation
  6. Listen in systole and diastole for extra heart sounds
  7. Listen in systole and diastole for murmurs
