This condition is more pronounced among individuals with darkly pigmented hair. Increased hair growth may or may not be associated with other signs of virilization when secondary male sexual characteristics are acquired by females

● What is koilonychia and what are possible causes?

○ Koilonychia (spoon nail) presents as a thin, depressed nail with the lateral edges turned upward (Fig. 9-6). This is associated with anemia or may be congenital. 15

● What is leukonychia and what is a possible cause?

○ Leukonychia appears as white spots on the nail plate (Fig. 9-8). This is usually caused by minor trauma or manipulation of the cuticle.

● What is clubbing? What does it represent?

○ Clubbing is present when the angle of the nail base exceeds 180 degrees (Fig. 9-9). It is caused by proliferation of the connective tissue, resulting in an enlargement of the distal fingers. Clubbing is most commonly associated with chronic respiratory or cardiovascular disease.

● What are Beau’s lines?

○ Beau’s lines manifest as a groove or transverse depression running across the nail. They result from a stressor such as trauma that temporarily impairs nail formation. The groove first appears at the base of the nail by the cuticle and moves forward as the nail grows out.

● What would indicate a positive wood’s lamp assessment?

○ Use a Wood’s lamp to identify fluorescing lesions, indicating fungal infection. Darken the room and shine the light on the area to be examined. If there is no fungal infection, the light tone on the skin appears soft violet

○ A yellow-green or blue-green fluorescence indicates the presence of fungal infection.

Module 4: Cardiovascular

Chapter 12: Cardiovascular

● Review the anatomy and physiology of the cardiovascular system.

○ The anatomy of the cardiovascular system includes the heart, blood vessels

○ The cardiovascular system transports oxygen, nutrients, and other substances to body tissues and metabolic waste products to the kidneys and lungs. This dynamic system is able to adjust to changing demands for blood by constricting or dilating blood vessels and altering the cardiac output.

● Describe the locations of assessment for the following pulses:

○ Temporal Pulse

■ not routinely assessed

■ Lateral side of each eyebrow

■ Assess perfusion and pain

○ Carotid Pulse

■ used in CPR assessments for adults

■ Medial edge of sternocleidomastoid muscle in lower third of neck

■ Palpate 1 at a time to avoid reducing blood flow to brain

■ Nursing Dx Example: Decreased Cardiac Output r/t altered afterload (decreased peripheral pulses) AEB pulses of 1+ in dorsalis pedis

○ Brachial Pulse

■ used in CPR and cap refill for infants/small children

■ Palpate groove between biceps and triceps just medial to bicep tendon at the antecubital fossa

○ Radial Pulse

■ Thumb side of forearm at the wrist

■ Assess together to assess equality

○ Ulnar Pulse

■ Located on medial side of forearm

○ Popliteal Pulse

■ (Advanced Practice)

■ Artery behind the knee to assess perfusion

■ Place patient in prone position with leg slightly flexed

○ Posterior Tibial Pulse

■ Inner aspect of ankle below and slightly behind the medial malleolus

○ Dorsalis Pedis Pulse

■ Dorsum of foot between extension tendons of 1st and second toes

● Describe the process for auscultation of bruits in the carotid artery.

○ Bruits

■ low-pitched blowing sounds usually heard during systole that indicate occlusion of the vessel (occlusion of a carotid artery may impair perfusion of the brain and increase the risk for TIA, transient ischemic attack)

■ perform when the patient has a h/o atherosclerosis, dizziness, or syncope

○ Procedure:

■ Use the bell of the stethoscope to auscultate the carotid artery

■ Ask the patient to hold his or her breath while you listen (Fig. 12-34).

■ Finding: You should hear no sound over these arteries.

● Describe the process for assessment of the jugular vein for pulsations.

○ Expected Finding:

■ Elevate HOB 30-45 degrees

● Can be as high as 90 degrees if venous pressures is elevated

■ Elevate chin slightly and tilt head away from side being examined

■ Use penlight to create tangential light

■ Observe for pulsations (expected), shouldn’t be able to visualize vein itself

○ Unexpected Findings:

■ Right-sided heart failure

● Irregular rhythms

● Prominent waves

● Describe the expected heart rate findings for the rate, rhythm, amplitude, and contour.

○ Rate:

■ Newborn 120-160 beats/min

● Describe the assessment for orthostatic hypotension.

○ Orthostatic Hypotension

■ Changes in B/P greater than 20 mmHg when changing positions

■ Generally associated with fluid volume deficit, antihypertensive medications or prolonged bed rest

● Review assessment technique for skin turgor and extremity symmetry.

○ Extremities:

■ When one arm is larger in circumference than the other, it could be caused by lymphedema

■ When the skin does not fall back into place, or tenting, indication of reduced fluid in the interstitial space from fluid volume deficit

○ Procedure:

■ Inspect the upper extremities comparing the size and proportion

■ Pinch an area of the skin and release the skin; should return into place

■ Findings: limbs should appear symmetric; skin turgor should be elastic

● Describe the assessment process for edema and subsequent documentation.

○ Edema:

■ When edema is found, notice if it is unilateral or bilateral, the consistency is soft, firm or hard; or there is tenderness

■ When the indentation of the thumb or finger remains in the skin, or pitting edema, it is an indication of excess fluid in the interstitial space

● seen in venous thromboembolism (VTE) and venous insufficiency

○ Process:

■ press down on bony prominence, notice if indentation remains

● Review process for capillary refill

○ Capillary refill

■ Gentle pressure on nail bed

■ Assess brachial/femoral pulses for cap refill in infants

■ Should blanch and refill <2 sec.

■ Nails should be 160 degree

● Describe the significance of hair distribution, skin temperature, nail bed angles, superficial veins and gross sensation during the cardiovascular assessment process.

○ Abnormalities of integrity, color, temperature, capillary refill, and nail color and angle are similar to those described for the upper extremities.

○ Marked pallor or mottling when the extremity is elevated or any ulcerated digit tips may require further evaluation.

○ Arterial insufficiency may cause a decrease in or lack of hair peripherally or skin that appears thin, shiny, and taut.

○ Varicose veins appear as dilated, often tortuous veins when legs are in a dependent position.

○ Abnormalities include pain on palpation or the sensation of “stocking anesthesia,” wherein the legs feel numb in a pattern resembling stockings.

○ The skin should be intact, with color appropriate for race.

○ The skin should feel warm.

○ Capillary refill should be 2 seconds or less.

○ Women who do not shave their legs and men should have hair evenly distributed on upper and lower legs.

○ Nails should be pink, with an angle of 160 degrees at the nail bed.

○ Veins should not be visible.

○ Sensation of the legs should be present without tenderness or numbness.

● What is the significance of impaired peripheral pulses?

○ Impaired peripheral pulses may indicate arterial insufficiency.

● Be familiar with the topographic landmark abbreviations.

○ Cardiac Landmarks:

■ Aortic- 2nd ICS RSB

■ Pulmonic- 2nd ICS LSB

■ Erb's Point-3d ICS LSB

■ Tricuspid- 4th ICS LSB

■ Mitral- 5th ICS MCL

● Describe the differences between lift, heave, thrill and retraction.

○ Lift

■ A lift feels like a more sustained thrust than an expected apical pulse and is felt during systole.

○ Heave

■ A heave is a more prominent thrust of the heart against the chest wall during systole.

■ Lifts and heaves may occur from left or right ventricular hypertrophy caused by increased workload.

○ Thrill

■ A thrill is a palpable vibration over the precordium or artery: it feels like a fine, palpable, rushing vibration.

■ A thrill is associated with a loud murmur.

○ Retraction

■ a visible sinking in of tissues between and around the ribs.

■ Retraction begins in the intercostal spaces

■ It occurs with increased respiratory effort.

■ If additional effort is needed to fill the lungs, supraclavicular (above the clavicle) and infraclavicular (below the clavicle) retraction may be seen.

● Describe the location of the apical pulse.

○ Inspection

■ Rounded, symmetrical (Adults and Pediatric)

■ Slight retraction medial to left MCL at 4-5th ICS for Adults and Peds

● Examine 1st 24 hours of birth

● Examine day 2-3 to assess changes from fetal to systemic/pulmonary circulation

■ Apical pulse –moves laterally in ventricular hypertrophy (myocardium enlargement)

■ PMI down and medial in COPD (r/t overinflated lungs)

■ Apical pulsation after exertion in hyperthyroidism, left ventricular hypertrophy

● Describe the location, pitch, and pathophysiology of S1 and S2.

○ LUB

■ Closing of mitral (M1) and tricuspid (T1) valves

■ indicates beginning of systole

■ Lower in pitch than S2

■ Louder at apex

○ DUB

■ Closing of aortic (A2) and pulmonic (P2) valves

■ Indicates beginning of diastole

■ Higher in pitch than S1

■ Louder at base

● Describe the significance of abnormal heart sounds S3 and S4? When are these normal and/or abnormal? What disease process can they indicate?

○ S3:

■ During diastole, when 80% of the blood in the atria rapidly fills the ventricles, a third heart sound may be heard (S3). It is often heard at the apex. An S3 occurs after the S2 and lasts about the same time as it takes to say “me too.’’ The “me’’ is the S2, and the “too’’ is the S3. An S3 is normal in children and young adults. However, when an S3 is heard in adults over 30 years of age, it signifies fluid volume overload to the ventricle that may be caused by heart failure or mitral or tricuspid regurgitation.

○ S4

■ At the end of diastole, when atrial contraction completes the filling of the ventricle, a fourth heart sound may be heard (S4). An S4 occurs just before the S1 and lasts about the same time as it takes to say “middle.’’ The “mi’’ is the S4, and the “ddle’’ is the S1. An S4 is normal in children and young adults. However, when an S4 is heard in adults over 30 years of age, it signifies a noncompliant or “stiff’’ ventricle. Hypertrophy of the ventricle precedes a non-compliant ventricle. CAD major cause.

● What is a heart murmur? What’s the difference between a systolic and diastolic murmur?

○ Systolic Murmur

■ A murmur occurring during the ventricular ejection phase of the cardiac cycle is termed a systolic murmur. Most systolic murmurs are caused by obstruction of the outflow of the semilunar valves or by incompetent atrioventricular (AV) valves. The vibration is heard during all or part of systole. Other causes of systolic murmurs are structural deformities of the aorta or pulmonary

○ Diastolic Murmur

■ A murmur occurring in the filling phase of the cardiac cycle is termed a diastolic murmur. Incompetent semilunar valves or stenotic AV valves create diastolic murmurs. These murmurs almost always indicate heart disease. Early diastolic murmurs usually result from insufficiency of a semilunar valve or dilation of the valvular ring. Mid- and late-diastolic murmurs are generally caused by stenosed mitral and tricuspid valves that obstruct blood flow.

● List the information that needs to be included in the documentation of a heart murmur.

○ When you identify a heart murmur, consider the following for documentation:

■ Timing and Duration

● At what part of the cycle is the murmur heard?

● Is it associated with S1 or S2, or is it continuous?

■ Pitch

● Low pitches are best heard with the bell of the stethoscope.

■ Quality

● refers to the type of sound including a harsh sound; a raspy, machinelike sound; or a vibratory, musical, or blowing sound

■ Intensity

● Murmur intensity refers to how loud the murmur is:

○ Grade I is barely audible in a quiet room.

○ Grade II is quiet but clearly audible.

○ Grade III is moderately loud.

○ Grade IV is loud and associated with a thrill.

○ Grade V is very loud, and a thrill is easily palpable.

○ Grade VI is very loud, and a thrill is palpable and visible.

■ Location

● Where is the sound heard loudest? Most often it is over one of the five anatomic landmarks used to auscultate heart sounds

■ Example of Documentation: S1, grade II, low-pitch murmur auscultated at fifth ICS, MCL. No thrill palpable.

● Describe the basis of ECG tracings.

○

● Describe the follow up assessment required when asymmetry is noted in the upper or lower extremities.

○

● What is the significance of unilateral asymmetry versus bilateral edema?

○ Edema of both legs may be caused by fluid overload from systemic disease (e.g., heart failure, renal failure, or liver disease). Unilateral edema of an extremity may be lymphedema caused by occlusion of lymph channels (e.g., elephantiasis or trauma) or surgical removal of lymph channels (e.g., after mastectomy). Localized edema of one leg may be caused by venous insufficiency from varicosities or thrombophlebitis.

● What assessment is done to evaluate the competence of the venous valves? What are the expected versus the abnormal findings?

○ The Trendelenburg’s test evaluates the competence of venous valves and is performed on patients who have varicose veins. With the patient lying supine, the APRN lifts one leg to allow veins to empty and then helps the patient to stand. The procedure is repeated with the other leg. Competent veins fill slowly, while those with varicosities fill rapidly.

● How do you calculate the ankle brachial index (ABI)? What is the significance of an ABI of less than 0.4?

○ ABI, Ankle Brachial Index

■ estimate arterial occlusion, also known as the arm-to-ankle index, AAI

■ when the patient has peripheral arterial disease, the patient has impaired peripheral perfusion that is reflected in a lower systolic pressure in the leg than the arm, which reveals an ABI less than normal

○ Findings:

■ >1 is normal

■ 0.9 to 0.99 indicates some narrowing of arteries (borderline)

■ 0.80 to 0.89 indicates early stages of PAD

■ 0.5 to 0.79 indicates moderate PAD

■ Less than 0.4 indicates severe PAD

■ Severe PAD may lead to ischemia

○ Procedure:

■ ankle systolic blood pressure/brachial systolic blood pressure

■ With the patient in a supine position, take the brachial blood pressure in both arms using Doppler sound

■ Apply the blood pressure cuff above the ankle to measure the systolic pressure of the posterior tibial pulses using the Doppler
