Abnormal Lung Sounds Quiz

Adventitious Breath Sounds

• Abnormal lung sounds occur from air movement through moisture, mucus, or narrowed airways.
• Sudden opening of collapsed alveoli can also produce these sounds.
• Bronchial breath sounds: High-pitched, harsh sounds heard over the larynx and trachea; longer on expiration than inspiration.
• Bronchovesicular breath sounds: Moderate blowing sounds over the mainstem bronchus; inspiration equals expiration.

Signs of Oxygenation Issues

• Cyanosis: Bluish or grayish discoloration of skin due to inadequate oxygenation; assessed differently for light and dark skin tones.
• Diaphoresis: Excessive sweating with moist skin surface.
• Ecchymosis: Subcutaneous blood collection causing purplish discoloration.

Edema

• Defined as excess fluid in tissues, leading to swelling with taut, shiny skin.
• Pitting edema: Indentation remains after palpation; graded based on severity.
• Causes of edema include overhydration, heart failure, kidney failure, trauma, or peripheral vascular disease.

Jaundice

• Yellow skin due to elevated bilirubin levels; indicates liver or gallbladder disease.
• Typically begins in the sclera of the eyes before affecting the skin.
• Harder to detect in darker skin; examine sclera, oral mucous membranes, palms, and soles for yellowish discoloration.

Pallor and Petechiae

• Pallor: Skin paleness from decreased blood or hemoglobin; visible in lips, nail beds, and mucous membranes.
• Petechiae: Small hemorrhagic spots indicating capillary bleeding; assess location, color, and size.

Types of Health Assessments

• Comprehensive health assessment: Broad, includes full health history and physical assessment; provides baseline data.
• Emergency health assessment: Rapid, focused assessment during critical situations; prioritizes airway, breathing, circulation.
• Follow-up assessment: Conducted regularly to monitor health changes and effectiveness of interventions.
• Focused assessment: Specific to particular health concerns, often involving one or two body systems.

Physical Assessment Techniques

• Auscultation: Listening to body sounds with a stethoscope; characteristics include pitch, loudness, quality, and duration.
• Inspection: Deliberate observation for size, color, shape, movement, and symmetry; requires good lighting.
• Palpation: Using touch to assess temperature, turgor, consistency, and vibrations; different parts of the hand are suited for specific assessments.
• Percussion: Striking body to create sound for assessing tissue characteristics; suggests alterations or masses.

Body Measurements

• Body mass index (BMI): Weight-to-height ratio used to assess nutritional status and obesity risk; important for chronic disease risk.
• Waist circumference: Measurement at the umbilicus indicating abdominal fat and disease risk.

Skin Lesions

• Normal lesions remain consistent in color, with a diameter less than 6mm, regular borders, and symmetry.
• Conditions include melasma (chloasma), xerosis (dry skin), and impetigo (contagious infection).

Skin Cancers

• Melanoma: Skin cancer originating in melanocytes; evaluated using the ABCDEs (Asymmetry, Border, Color, Diameter, Evolving).
• Basal cell carcinoma: Common, typically appears as a transparent bump; occurs from UV exposure.
• Kaposi sarcoma: Lesions affecting those with weakened immune systems; linked to HHV-8.

Miscellaneous Skin Conditions

• Hyperemia: Redness from increased blood flow; fades when pressure is applied.
• Tinea capitis: Ringworm, a fungal infection causing ring-like rash.
• Acne: Inflammation due to clogged pores; can lead to cyst formation.

Testicular Self-Examination

• Recommended after warm baths/showers; normal testicles are smooth and uniform.
• Report any lumps or abnormalities.

Human Spine

• Comprised of 33 vertebrae in five regions: cervical, thoracic, lumbar, sacral, and coccygeal.

Lifespan Considerations in Assessment

• Comprehensive assessment includes evaluation of cognitive, psychosocial, and emotional development throughout different life stages.### Cultural Considerations and Patient Sensitivity
• Integrating cultural assessment into health assessments involves gathering cultural data from patients, families, and caregivers to improve care.
• Being sensitive to physiological and psychological patient needs, such as pain and anxiety, is vital during health assessments.

Patient Environment

• Privacy and respect are crucial during assessments; separate examination rooms enhance comfort in outpatient settings.

Nursing Role in Diagnostics

• Nurses play a critical role in diagnostic procedures, helping with patient preparation, obtaining consent, scheduling, and providing post-procedure education.
• Nurses are responsible for ensuring accurate and effective communication regarding tests, which contribute significantly to the overall health assessment.

Components of Health History

• Health history collections include various critical components that create a patient profile:
  • Biographical Data: Information like age, gender, occupation, and preferences is essential for understanding patients.
  • Reason for Seeking Care: Documenting the patient's own words enhances assessment focus.
  • Present Health Concerns: Exploring the onset, symptoms, and impacts of current health issues is necessary for accurate diagnosis.
  • Past Health History: Chronic illnesses and past treatments guide current care and risk identification.
  • Family Health History: Understanding genetic risks and exposure to family diseases assists in preventative care.
  • Functional Health: Evaluating a patient’s ability to perform daily activities indicates their quality of life and areas needing support.

Physical Assessment Techniques

• Systematic physical assessments collect objective data, often conducted in head-to-toe or body system sequences tailored to patient needs.
• Preparation is essential for patient comfort and includes appropriate communication and accessible, clean equipment.

Measurement Tools

• Thermometers and Blood Pressure Devices: Measure temperature and blood pressure; electronic devices are preferred for accuracy.
• Scales: Used for measuring weight and height; specialized scales accommodate various patient needs.
• Lighting and Tools: Proper lighting is essential; tools include otoscopes, stethoscopes, and rulers for assessments.
• Vision Testing: Snellen charts assess visual acuity; handheld tools can evaluate near vision.

Patient Positions During Assessment

• Various positions are utilized to assess different areas effectively, e.g., supine for vital signs and sitting for lung assessment.
• The choice of position depends on the patient’s condition and comfort level.

Four Techniques of Physical Assessment

• Inspection: Involves systematic visual observation and noting any audible or olfactory cues.
• Palpation: Utilizes touch to evaluate temperature, texture, and tenderness; technique varies by body area.
• Percussion: Taps on the body to determine the characteristics of underlying tissues; typically an advanced skill.
• Auscultation: Listens for internal sounds using a stethoscope; it requires a quiet environment for accurate assessment.

Assessment Overview

• General Survey: Initially assesses overall appearance, behavior, and critical health metrics like vital signs, waist circumference, and BMI.
• Vital Signs: Serve as vital indicators of health, including temperature, pulse, respiration, and blood pressure; pain is increasingly viewed as the fifth vital sign.
• Skin Assessment: Requires inspection for color, temperature, and lesions, along with the evaluation of potential systemic conditions.

Skin Color Changes

• Erythema: Redness indicates increased blood flow, associated with trauma or infection.
• Cyanosis: Bluish tinge suggests inadequate oxygenation, notably in extremities and mucous membranes.
• Jaundice: Yellowing may indicate liver dysfunction; first evident in sclera and mucous membranes.
• Pallor: Lack of color often points to anemia or shock; assess in mucous membranes and conjunctivae.
• Vitiligo: Identifies localized skin depigmentation linked to autoimmune disorders, manifesting as white patches.

Practical Considerations for Effective Assessment

• Ensure all assessment techniques are performed systematically and are adapted to the patient’s comfort and needs.
• Engaging with the patient using therapeutic communication throughout the assessment fosters trust and facilitates more accurate data collection.### Skin Assessment
• Pallor in dark-skinned individuals may appear as an ashen gray or yellow hue.
• Inspect skin for vascularity, bleeding, or bruising; signs may indicate cardiovascular, hematologic, or liver issues.
• Ecchymosis is subcutaneous bleeding causing a purplish discoloration, while petechiae are small hemorrhagic spots from capillary bleeding.
• Assess lesions for size, shape, depth, location, and drainage; lesions include bruises, cuts, and insect bites.
• Normal skin is warm and dry; increased temperature and moisture may indicate fever.
• Skin texture varies from smooth and soft to rough and dry; dehydration results in dry, loose skin.
• Turgor indicates skin elasticity; normal skin folds return to shape upon release, while dehydrated skin returns slowly.
• Edema is fluid accumulation causing swelling; pitting edema leaves an indentation upon pressure release.
• Nail assessment includes observing shape, angle, texture, and color; normal nails have a convex shape and an angle of about 160 degrees.
• Abnormal nail findings may include infections, separation, brittleness, and clubbing related to reduced oxygen levels.

Hair and Scalp Assessment

• Hair should be resilient, evenly distributed, and not excessively dry or oily.
• Abnormal findings include alopecia (baldness) and hirsutism (excessive hair growth); both can result from various health issues.
• Inspection of the scalp should note color, dryness, lumps, lesions, or lice.

Age-Related Skin Variations

• Infant/Child Variations:
  • Newborns can display jaundice and milia.
  • Lanugo (fine downy hair) may be present for the first two weeks.
  • Skin is typically smooth and thin.
  • Pubic hair develops at puberty.
• Older Adult Variations:
  • Common signs include wrinkles, dryness, senile keratosis, age spots, and cherry angiomas.
  • Hair may become fine, brittle, or gray, and hair loss occurs.
  • Women may experience coarse facial hair; men may notice decreased body hair.

Head and Neck Assessment

• Evaluation involves examining the skull, face, eyes, ears, nose, mouth, throat, trachea, thyroid, and lymph nodes.
• Document any reported headaches or dizziness; incorporate smoking cessation into the care plan if applicable.
• Inspection assesses facial symmetry, color, and hair distribution; abnormalities include facial edema or involuntary movements.

Eye Assessment

• Inspection of the external structures and testing visual acuity is crucial; use a penlight and eye chart.
• Pupillary reaction should involve constriction to direct light (direct response) and consensual constriction of the opposite eye.
• Accommodation test: Pupils constrict when looking at near objects and dilate for distant objects.
• Convergence assessment checks eye alignment as the finger approaches the nose.

Ear and Nose Assessment

• External ear examination includes inspection and palpation; assess hearing and sound conduction as well.
• For the nose, examine patency, occluding one nostril at a time to evaluate inhalation/exhalation.
• Inspect nasal mucosa for color and lesions; it should be moist and darker red than oral mucosa.

General Observations

• Careful assessment and documentation are critical in identifying abnormal signs during skin, hair, nails, eyes, ears, and nose examinations.
