NCLEX Cardiovascular Assessment: Pulses, Edema & JVD

bolt The 60-second version

Every cardiovascular NCLEX-RN item starts with assessment. This guide covers the bedside skills the exam expects: where to listen to the heart, how to grade pulses and edema, how to check capillary refill, jugular venous distension, and orthostatic vital signs, and how to tell arterial from venous insufficiency.

check_circleAuscultation sites: aortic (2nd right intercostal space), pulmonic (2nd left), Erb's point (3rd left), tricuspid (4th left sternal border), mitral (5th intercostal space, midclavicular line — the apical pulse).
check_circlePulses are often graded 0 (absent) to 4+ (bounding), with 2+ normal; always compare both sides.
check_circleCapillary refill is normally under about 2–3 seconds; longer suggests poor perfusion.
check_circleJugular venous distension: assess with the head of the bed at 30–45°; distension well above the sternal angle suggests high right-sided pressure.
check_circleOrthostatic hypotension: systolic fall of at least 20 mm Hg or diastolic fall of at least 10 mm Hg within 3 minutes of standing.
check_circleArterial insufficiency: cool, pale, weak pulses, painful toe ulcers. Venous insufficiency: edema, brown discoloration, ulcers near the medial ankle, normal pulses.

Heart sounds and auscultation

Listen in a consistent sequence with the diaphragm, then the bell for low-pitched sounds.

Area	Location	Best for
Aortic	2nd intercostal space, right sternal border	S2; aortic stenosis murmur
Pulmonic	2nd intercostal space, left sternal border	S2 splitting
Erb's point	3rd intercostal space, left sternal border	S1 and S2 together
Tricuspid	4th intercostal space, left lower sternal border	S1; right-sided murmurs
Mitral (apical)	5th intercostal space, midclavicular line	S1, S3, S4; apical pulse

S3 and S4 are low-pitched: listen with the bell, client in the left lateral position.

Extra heart sounds. A new S3 in a client with heart failure is a sign of fluid overload to report.

Pulses, capillary refill, and edema

Peripheral assessment shows how well the heart and vessels are perfusing tissue.

Pulse grading. Some facilities use a 0–3+ scale; document using your facility's scale and compare sides.

Assessment	Normal	Concerning
Capillary refill	Under about 2–3 seconds	Delayed: shock, dehydration, arterial disease
Pitting edema	None	Graded 1+ (slight) to 4+ (deep, lasting pit); note location and whether it is new
Skin temperature and color	Warm, consistent with body	Cool, pale, mottled, or cyanotic
Pulse deficit	Apical equals radial	Apical faster than radial (atrial fibrillation)

After cardiac catheterization or vascular surgery, check pulses, color, warmth, and sensation distal to the site.

Jugular veins and orthostatic vital signs

These two bedside checks reflect volume status from opposite directions.

Orthostatic vital signs. Stop if the client becomes dizzy or faint; a large rise in heart rate also suggests volume depletion.

Jugular venous distension: raise the head of the bed to 30–45° and look at the internal or external jugular vein. Distension high above the sternal angle suggests right-sided heart failure, fluid overload, tamponade, or tension pneumothorax.
Flat neck veins in a supine client suggest volume depletion.
Pulse pressure (systolic minus diastolic) is normally about 40 mm Hg; a narrowing pulse pressure can signal falling cardiac output, and a widening one can occur with aortic regurgitation or rising intracranial pressure.

Arterial vs venous insufficiency

A frequent comparison item: the findings point in opposite directions.

Positioning differs: keep the legs dependent (not elevated) for arterial disease; elevate the legs for venous insufficiency. Compression is used for venous disease only after arterial disease is excluded.

NGN-style case

Combining several assessment findings.

functions Clinical judgment case — after cardiac catheterization

Two hours after a femoral cardiac catheterization, the nurse finds the affected foot cool and pale, capillary refill 5 seconds, and the dorsalis pedis pulse absent (it was 2+ before the procedure). The site has no hematoma. What should the nurse do?

Recognize cues: new loss of pulse, coolness, pallor, delayed capillary refill in the affected leg.
Analyze: possible arterial occlusion (thrombus or dissection) — a limb-threatening emergency.
Confirm with a Doppler if available, but do not delay.
Notify the provider immediately; keep the leg straight and maintain bed rest as ordered.

Answer. Notify the provider immediately. A new absent pulse with a cool, pale limb suggests arterial occlusion.
