Lab Refresher: Normal Cardiac/Vascular exam Flashcards

1
Q

When do you use the Diaphragm vs. Bell, what does each help you listen to?

A

Diaphragm - high pitched sounds (S1, S2, AR, MR, Friction Rubs)

Bell - low pitched (S3, S4, MS, carotid bruit)

Q

Criteria (size) when palpating for impulse?

A

Small, brisk beat measuring less than 2.5 cm, should last the first 2/3 of systolic period (or less).

Q

What is an S3 sound?

A
  • Dull, low pitch (heard w/ bell)

- Due to high pressures and abrupt deceleration of inflow across the mitral valve at the end of rapid filling phase

Q

Diastolic murmurs may indicate which pathologies?

A
  • Aortic regurgitation
  • Pulmonic regurgitation
  • Mitral stenosis
  • Tricuspid stenosis
18
Q

How is JVP measured and what is normal?

A
  • Pt placed supine to allow veins to engorge, then raise to 30-45 degrees

Normal: 0-9

19
Q

Where is carotid pulse felt, and how do you assess both?

A
  • Medial to the SCM

- Only assess ONE AT A TIME!!!

20
Q

How are pulses graded?

A
4+ Bounding
3+ Strong, full, increases
2+ Normal, average intensity
1+ Diminished, barely palpable
0 Absent, not palpable
21
Q

What is the normal capillary refill time?

A

2 seconds or less

22
Q

Examining for pitting edema is done by pressing firmly for 5 seconds in which 3 locations?

A

1) Dorsum of foot
2) Anterior tibia
3) Behind medial malleolus

23
Q

What is the 4 point grading for edema?

A
  • Absent
  • 1+ Barely detectable, slight pitting (2mm); disappears rapidly

2+ Slight indentation (4mm); 10-15 secs

3+ Deeper indentation (6mm); may be >1 min

4+ Very marked indentation (8mm); 2-5 minutes

24
Q

Increased JVP in?

A
  • SVC obstruction
  • Severe heart failure
  • Constrictive pericarditis, cardiac tamponade, RV infarction
  • Restrictive cardiomyopathy
25
What is the normal ejection fraction %?
50-60%
26
Steps to CV exam in order
1. Inspection 2. Palpation 3. Percussion 4. Auscultation
27
When palpating PMI what are the normal characteristics that should be felt and should last how long?
- Small, brisk beat and measure <2.5 cm | - Should last the first 2/3 of systolic period (or less)
