  21. 22. Heart Murmurs
  22. 23. Murmurs <ul><li>Blowing, swooshing sound </li></ul><ul><li>Indicates abnormal turbulent blood flow </li></ul><ul><li>A murmur outside the heart is called a bruit </li></ul><ul><li>Are either systolic or diastolic </li></ul><ul><li>Systolic murmur may occur innocently in children and young adults r/t increased force of contraction </li></ul>
  23. 24. Assessment of Murmurs <ul><li>Timing - systolic or diastolic </li></ul><ul><li>Loudness -Grade I thru VI </li></ul><ul><li>Pitch- high or low </li></ul><ul><li>Pattern- Crescendo, decrescendo, plateau, diamond </li></ul><ul><li>Quality- Musical, blowing, harsh or rumbling </li></ul><ul><li>Location- Where is it loudest? </li></ul><ul><li>Radiation- Is it audible in other parts of precordium </li></ul><ul><li>Posture- Is it present or louder only in certain position </li></ul>
  24. 26. Age Specific Considerations <ul><li>Infants </li></ul><ul><ul><li>Use appropriate size stethoscope </li></ul></ul><ul><ul><li>May be irregular </li></ul></ul><ul><ul><li>Murmurs may be present r/t congenital fetal circulation remnants </li></ul></ul><ul><li>Children </li></ul><ul><ul><li>May have visible apical pulses r/t thin chest wall </li></ul></ul><ul><ul><li>May have innocent murmurs-always note presence of murmur </li></ul></ul>
  25. 27. Age Specific Consideration cont <ul><li>Pregnancy </li></ul><ul><ul><li>Increased pulse rate </li></ul></ul><ul><ul><li>Exaggerated S2 splitting </li></ul></ul><ul><ul><li>Easily heard S3 </li></ul></ul><ul><ul><li>Systolic murmur may be present-should disappear /p delivery </li></ul></ul><ul><li>Elderly </li></ul><ul><ul><li>S4 even /s Hx of CAD </li></ul></ul><ul><ul><li>Irregular pulse more common </li></ul></ul>
  26. 28. Practice Exam Question <ul><li>You are assessing a 7 year old child upon admission to the pediatric unit. The child has a soft systolic murmur. His Mother states he has always had this murmur and the doctor is aware of it. How should you document your finding? </li></ul><ul><ul><li>A. No need to document it as it is an innocent murmur. </li></ul></ul><ul><ul><li>B. Describe murmur location, pitch and loudness in the nurses notes but no need to mention it to the Doctor. </li></ul></ul><ul><ul><li>C. Document your finding in the nurses notes and mention your finding to the Doctor. </li></ul></ul><ul><ul><li>D. Document you findings on the graphic sheet. </li></ul></ul>
  27. 29. Rationale <ul><li>C is the correct answer as the murmur is an abnormal finding </li></ul><ul><li>A is incorrect because you always document an abnormal finding </li></ul><ul><li>B is incorrect because the Physician should be aware of all abnormal findings </li></ul><ul><li>D is the wrong form </li></ul>
  28. 30. Peripheral Vascular system and Lymphatics Nursing 330 Governors State University Shirley Comer
  29. 31. Anatomy in Peripheral Vascular <ul><li>Arteries- carry oxygenated blood to tissues </li></ul><ul><ul><li>Thick muscular walled </li></ul></ul><ul><li>Veins - carry deoxygenated blood to tissues </li></ul><ul><ul><li>Thin walled </li></ul></ul><ul><li>Lymphatics- separate vessel system which retrieves excess fluid and plasma proteins and returns them to blood stream </li></ul><ul><ul><li>Major player in immune system </li></ul></ul><ul><ul><li>Contains nodes that drain body areas </li></ul></ul>
  30. 32. Assess Arms <ul><li>Note color of skin and nails, temperature, texture, turgor, hair distrubuiton </li></ul><ul><li>Note lesions, edema or clubbing </li></ul><ul><li>Assess capillary refill </li></ul><ul><li>Assess radial and antecubital pulse (0 to 4+) </li></ul><ul><li>Palpate antecubital and axillary lymph nodes </li></ul><ul><li>All finding should be bilateral </li></ul><ul><li>Edema indicates lymphatic obstruction (lymphedema) </li></ul>
  31. 33. Pulse Assessment <ul><li>Pulses are rated 0 to 4+ </li></ul><ul><li>3+ is normal </li></ul><ul><li>Note rate, amplitude and rhythm </li></ul><ul><li>Documenting in the physical assessment </li></ul>Pulse Radial Carotid Brachial Apical Femoral Pop Post Tib Dorsal Ped Left 3+ 3+ 3+ n/a 2+ 2+ 1+ 1+ Right 3+ #+ 3+ n/a 2+ 2+ 1+ 0
  32. 34. Assess the legs <ul><li>Inspect skin </li></ul><ul><ul><li>Note: color, hair distribution, venous pattern, size, edema, lesions, temperature, turgor, texture </li></ul></ul><ul><ul><li>Should be symmetrical </li></ul></ul><ul><li>Venous pattern </li></ul><ul><ul><li>Normally flat and barely visible </li></ul></ul><ul><ul><li>Vericose vein-enlarged surface vein, tortuous, prone to clots </li></ul></ul><ul><ul><li>Note angiomas, petichia, purpuras, brusing ect </li></ul></ul>
  33. 35. Assess the Legs cont <ul><li>Palpate Inguinal lymph nodes </li></ul><ul><li>Palpate Peripheral pedal pulses- use doppler if unable to find </li></ul><ul><ul><li>Femoral pulse </li></ul></ul><ul><ul><li>Popliteal pulse-can be difficult to locate </li></ul></ul><ul><ul><li>Posterior Tibial pulse- behind medial malleolus </li></ul></ul><ul><ul><li>Dorsal pedis pulse- lateral to extensor tendon of great toe- use light touch </li></ul></ul>
  34. 36. Edema <ul><li>Pretibial- </li></ul><ul><ul><li>Firmly press over skin of tibia or medial malleolus for 5 seconds and release. </li></ul></ul><ul><ul><li>If indentations are left pt has pitting edema. </li></ul></ul><ul><ul><li>Scale 0 to 4+ </li></ul></ul><ul><li>Unilateral edema may indicate venous thrombosis, lymph obstruction, injury or dependant positioning </li></ul>
  35. 37. Practice Exam Question <ul><li>Your patient has a history of a mastectomy on the right side. You note her right arm is twice the size of the left. What nursing intervention would you use to decrease the size of this arm? </li></ul><ul><li>A. elevate arm on pillow </li></ul><ul><li>B. encourage ROM exercises </li></ul><ul><li>C. discouarage constricting clothing </li></ul><ul><li>D. all of the above </li></ul>
  36. 38. Rationale <ul><li>D is the correct answer. The pt is experiencing lymphedema as a result of her mastectomy and all the interventions listed are appropriate. </li></ul>
