health assessment 5

Sequence of Assessment: The standardized sequence for assessing the carotid arteries is Inspection, followed by Auscultation, and then Palpation.
Auscultation Technique: * Instruct the patient to look the opposite direction of the side being examined. * Listen for a duration of $30\,\text{seconds}$ on each side. * If the sounds are unclear or if abnormal noises are detected, auscultate for a full $1\,\text{minute}$ .
Abnormal Finding - Bruits: * Definition: A bruit is an extra "whooshing" or turbulent sound caused by blood flow through a narrowed or obstructed vessel. * Potential Causes: Clots, murmurs, or arterial stenosis. * Clinical Action: If a bruit is heard via auscultation, the clinician should not proceed with palpation, as this could potentially dislodge extra movement in the blood. The findings must be reported to a doctor immediately.

Vessel Identification: The jugular vein is the peripheral neck vessel located upper in the neck area, usually parallel to the neck tendons.
Patient Positioning: * The patient must be in a supine position with the head on a pillow. * The head of the bed must be elevated to an angle between $35^{\circ}$ and $45^{\circ}$ . * Rationale for Positioning: If the patient is too flat, clinicians cannot accurately see the vein based on the effects of gravity; elevation is required to visualize potential distension.
Normal Findings: The normal finding is the absence of a noticeable jugular vein upon inspection (no bulging).
Abnormal Findings - Distension: * Description: A visible bulge or vein distension extending down the neck. * Clinical Significance: Jugular vein distension is a primary sign of heart failure. * Mechanism: Inadequate heart pumping leads to higher systemic blood pressure, which pushes the vessels to enlarge and become visible because the heart is working excessively.

General Inspection: Before palpation or auscultation, inspect the thoracic cavity and the pericardium for bumps, lesions, or bulging.
The Apical Impulse: * Anatomical Location: The apical impulse is located at the apex of the heart, which is anatomically the bottom point of the heart. * Specific Landmark: The $5\text{th intercostal space}$ at the midclavicular line ( $MCL$ ). * Anatomical Cheat Sheet: For female patients, this roughly aligns with the bra line or just under the nipple line.
Step-by-Step Landmarking Procedure: 1. Locate the Clavicle. 2. Place one finger directly underneath the clavicle to feel the first rib (this may feel uncomfortable/painful when pushed). 3. The space below the first rib is the first intercostal space. 4. Place two fingers under the clavicle to quickly find the $2\text{nd intercostal space}$ . This is the starting point for cardiac auscultation. 5. Continue palpating downward to locate the $3\text{rd}$ , $4\text{th}$ , and finally the $5\text{th intercostal space}$ .
Clinical Sensitivity: When assessing patients with large amounts of adipose tissue or large breasts, the clinician must move the tissue to landmark correctly. This must be done with consent and through the lens of trauma-informed care and privacy.

Technique: Palpate across the precordium using the palm of the hand. The assessment is usually done bilaterally to compare sides.
Normal Findings: Absence of lumps, bumps, extra pulsations, thrills, or heaves.
Thrills: * Analogy: Described as the "purring of a cat." * Detection: Usually felt with the upper part of the palm. * Description: These are finer, higher-frequency vibrations caused by turbulent blood flow or vessel vibrations. * Location: Can be felt throughout the precordium.
Heaves (Lifts): * Detection: Felt as deeper, stronger vibrations or pulsations, typically with the base/bottom of the palm. * Frequency: A lower frequency tone compared to thrills. * Clinical Significance: Heaves are usually a sign of Left Ventricular Hypertrophy ( $LVH$ ). * Mechanism: Chronic heart failure causes the muscle ( $\text{trophy}$ ) to enlarge ( $\text{hyper}$ ), leading to struggling pulsations or quivering. * Primary Location: Predominantly felt at the apical impulse.

Auscultation Sequence: The clinician follows a "Z-pattern" starting from the upper right, moving across to the upper left, down the left sternal border, and laterally to the apex.
Valve Landmark Specifics: 1. Aortic Valve: Located at the $2\text{nd intercostal space}$ , right sternal border. 2. Pulmonic Valve: Located at the $2\text{nd intercostal space}$ , left sternal border. 3. Erb’s Point: Located at the $3\text{rd intercostal space}$ , left sternal border. This is a primary location for hearing $S2$ clearly. 4. Tricuspid Valve: Located at the $4\text{th}$ (or $5\text{th}$ ) intercostal space, left sternal border. 5. Mitral Valve: Located at the $5\text{th intercostal space}$ , midclavicular line (the apical impulse area).
Heart Sounds: * $S1$ and $S2$ : The standard "lub-dub" sounds that should be clear and loud, especially at Erb's point and the apical impulse. * $S3$ and $S4$ : Extra beats that are considered abnormal (murmurs). These indicate where structural issues may exist (e.g., if louder at the aortic landmark, it suggests aortic valve stenosis).

Stethoscope Components: * Diaphragm (Large Side): Used for high-pitched sounds like $S1$ , $S2$ , and extra beats ( $S3$ , $S4$ ). * Bell (Small Side): Used for low-pitched sounds, such as bruits and murmurs.
Equipment Check: Ensure the stethoscope is "clicked" into the correct position (open) before use. Test by tapping the diaphragm while the earpieces are in.
Left Lateral Decubitus Position: * If heart sounds are quiet or abnormal noises are suspected, ask the patient to turn onto their left side. * Rationale: This position creates extra pressure and turbulent flow, making quiet noises more audible by displacing the heart closer to the chest wall. * Auscultation in Position: Listen at the apical impulse for a full minute with the bell to detect bruits or extra wishing sounds.

Question: What happens if my patient has large breasts or adipose tissue?
Response: You must move the tissue to reach the landmark. You must obtain consent and practice trauma-informed care while maintaining privacy.
Question: When do we hear the bruits?
Response: We listen for bruits in the neck vessels using the bell of the stethoscope to hear extra whooshing sounds of turbulent blood flow.
Student Inquiry: A student asked about the specific landmarks on a chart.
Response: The instructor referred students to the weekly slides/powerpoint for a visual screenshot of the valve locations and clarified the count of the intercostal spaces ( $1\text{st}$ through $5\text{th}$ ).
