Exam 3 Flashcards
Location of the apical pulse
5th ICS at the MCL
How to palpate apical pulse
Remain on pt right side, have pt supine, use finger pads
When auscultating the heart what do you listen for first?
HR and rhythm
When auscultating the heart what do you listen for after identifying the HR and rhythm?
S1 and S2
What is S1? Where is it the loudest?
“lub” starts systole
Closure of AV valves (bi and tricuspid)
Loudest at apex of heart
What is S2? Where is it the loudest?
“dub” starts diastole
Closure of semilunar valves (aortic and pulmonary)
Loudest at the base of the heart
What is a thrill?
Palpable vibration/pulsation over precordium or artery
What is a bruit?
Swishing sound caused by turbulent blood flow through a narrowed vessel
What is the main difference b/w a bruit and a thrill?
Bruit you hear, thrill you palpate/feel
How do you assess the size of the aorta?
Palpate deep in the epigastrium left of the midline.
Width can be measured by placing both palms on the abdomen with 1 index finger extended on either side of the aorta
What is a weak pulse indicative of?
Hypovolemia, shock, decreased cardiac output
What is a strong and bounding pulse typically caused by?
Hypervolemia
Pulse amplitude scale: 1+
weak, diminished (easy to obliterate)
Pulse amplitude scale: 2+
Normal (obliterate w moderate pressure)
This is what we want the pulse to be
Pulse amplitude scale: 3+
Strong (obliterate w firm pressure)
Pulse amplitude scale: 4+
Bounding (unable to obliterate)
Pulse amplitude scale: 0
Pulse is absent
Where is the radial artery?
Extends down the thumb side of the arm
Where is the ulnar artery?
Extends down the pinky side of the arm
Where can you palpate the femoral artery?
Just under the inguinal ligament
Where is the posterior tibial artery?
B/w the medial malleolus and achilles tendon
Palpated behind the medial malleolus of the ankle
Where is the dorsalis pedis artery palpated?
On top of the foot by the big toe side
What is a doppler used for?
To find a pulse you cannot palpate
How do you measure the ankle-brachial index?
Systolic BP of ankle divided by systolic BP of arm
Why would we measure the ankle-brachial index?
If the pt has arterial occlusion
What is a pulse deficit?
Difference b/w the apical and peripheral/radial pulses
How do you assess for a pulse deficit?
Palpate the radial pulse while auscultating the apical pulse for one full minute, they should be identical
What would indicate the need to assess for a pulse deficit?
An irregular rhythm
What are common causes of a pulse deficit?
A-fib, atrial flutter, premature ventricular contractions, heart block
Describe pallor
Loss of color
Tone may go from pale to ashen
Seen in arterial insufficiency, decr blood supply, and anemia
Describe the color of cyanosis in light and dark skinned people
Blue tinge of skin for light skin
Darker skin may appear blue, dull, or lifeless
Central cyanosis is seen where?
Caused most frequently by what?
Seen around the mouth - assess mucous membrane/oral mucosa
Usually d/t resp prob or cardiopulmonary prob
Peripheral cyanosis is seen where?
Caused most frequently by what?
Seen in the nail bed or conjunctiva and extremities
D/t circulatory prob (vasoconstriction)
