Health Assessment

LPN Fundamentals: Comprehensive Health Assessment Unit Overview

  • Definition: Health assessment is defined as a systematic evaluation of a patient's physical condition and health history. It is the core foundation upon which nursing care is built.
  • Importance of Assessment:
    • Provides the basis for accurate nursing diagnoses.
    • Serves as a guide for developing comprehensive treatment plans.
    • Facilitates the measurement of patient progress over time.
  • Core Components:
    • Health History: Subjective data regarding the patient's past and present status.
    • Physical Examination: Objective data collected through direct observation and inspection.
    • Review of Diagnostic Data: Analysis of laboratory results and other clinical tests.
  • Unit Objectives:
    • Define terminology related to the Review of Systems (ROS).
    • Investigate specific nursing considerations for ROS.
    • Examine appropriate nursing diagnoses and interventions for ROS.
    • Describe fundamental nursing practice principles, systems, and techniques.
    • Discuss therapeutic care regarding safety and medication administration precautions.
    • Integrate critical thinking and leadership skills to improve the quality of client care delivery.
    • Differentiate considerations for specific populations: gerontological (elderly), pediatric (children), and various cultural groups.

Ethnic, Cultural, and Spiritual Aspects of Care

  • Cultural Competence:
    • Nurses must recognize diverse beliefs and practices.
    • Care approaches should be adapted to respect varying cultural values and backgrounds.
  • Cultural Sensitivity:
    • Understanding how culture influences a patient's health perceptions.
    • Symptoms and concerns voiced by the patient must be interpreted within their specific cultural context.
  • Spiritual Considerations:
    • Nurses should acknowledge the vital role faith plays in the healing process.
    • Spiritual beliefs must be incorporated into the care plan, as they significantly impact treatment acceptance and patient compliance.

Systematic Physical Assessment: Head-to-Toe Approach

  • Head and Neck:
    • Examine the scalp for integrity and the face for symmetry.
    • Evaluate neck mobility.
    • Check lymph nodes, the thyroid gland, and palpate carotid pulses.
  • Chest and Back:
    • Assess respiratory rate and effort.
    • Auscultate heart sounds.
    • Inspect spinal alignment and look for abnormal findings in the lungs or heart regions.
  • Abdomen:
    • The assessment sequence is: Observe (Inspect), Auscultate (listen), Percuss (tap), and Palpate (feel).
    • Assess for tenderness, the presence of masses, or organ enlargement.
  • Extremities:
    • Evaluate range of motion (ROM) and arterial pulses.
    • Assess skin condition and integrity.
    • Observe the patient's gait and balance during movement.

Health History Data Collection

  • Subjective Data:
    • Information reported directly by the patient.
    • Includes symptoms (e.g., pain), feelings, and personal experiences regarding their illness.
  • Objective Data:
    • Observable and measurable clinical findings.
    • Includes vital signs, physical examination findings, and laboratory/diagnostic test results.
  • Key History Components:
    • Chief Complaint: The primary reason the patient is seeking care.
    • History of Present Illness (HPI): Detailed exploration of current symptoms including onset, duration, and severity.
    • Past Medical History (PMH): Previous illnesses, surgeries, hospitalizations, childhood diseases, and immunizations.
    • Family Health Patterns: Identification of familial diseases (diabetes, heart disease, cancer). A three-generation genogram is recommended.
    • Social History: Lifestyle factors (diet, exercise, substance use), occupation, and the home environment.

Vital Signs and Baseline Data

  • Baseline Physical Data:
    • Height and Weight: Measured using calibrated equipment. Used to calculate Body Mass Index (BMI) to assess nutritional status and health risks.
    • Skin Integrity: Assessment of color, texture, turgor, and moisture. All lesions, wounds, or pressure areas must be documented.
  • The Six Vital Signs:
    1. Temperature: Normal range is 97.8∘F−99.1∘F97.8^\circ\text{F}-99.1^\circ\text{F} (36.5∘C−37.3∘C36.5^\circ\text{C}-37.3^\circ\text{C}). Routes include oral, rectal, axillary, or tympanic.
    2. Pulse: Normal adult range is 60−10060-100 beats per minute. Assessment includes rate, rhythm, and strength.
    3. Respiration: Normal adult range is 12−2012-20 breaths per minute. Nurses should note depth, pattern, and effort.
    4. Blood Pressure: Normal adult range is <120/80 mmHg<120/80\,\text{mmHg}. Factors affecting BP include age, activity, and health status.
    5. Pain: Considered the "subjective fifth vital sign." Assessed using a standardized scale of 0−100-10.
    6. Oxygen Saturation (SpO2SpO_2): Normal range is 95−100%95-100\%. Measured via pulse oximeter on the finger or earlobe.

Blood Pressure Assessment Details

  • Hypotension: Defined as blood pressure below 90/60 mmHg90/60\,\text{mmHg}. Potential causes include shock, dehydration, or medication side effects. Common symptoms include dizziness and fainting.
  • Hypertension: Defined as blood pressure above 130/80 mmHg130/80\,\text{mmHg}. Risk factors include obesity, smoking, and family history. Chronic hypertension can lead to heart disease.
  • Clinical Best Practices:
    • Verify abnormal readings with repeat measurements.
    • Ensure the patient's arm is supported at heart level during the measurement.

Assessment Tools and Techniques

  • Stethoscope:
    • Diaphragm: Position firmly against the skin for high-pitched sounds.
    • Bell: Used for low-pitched sounds, such as heart murmurs.
    • Device must be cleaned between every patient.
  • Sphygmomanometer:
    • Select the appropriate cuff size for the patient.
    • Position at heart level.
    • Inflate the cuff to 30 mmHg30\,\text{mmHg} above the expected systolic pressure.
  • Digital Tools: Ensure proper calibration and strictly follow manufacturer instructions for accuracy.

Neurological Examination and Orientation

  • Insertion Procedure:
    1. Select site (start distal and move proximal).
    2. Clean site with antiseptic and allow to dry.
    3. Stabilize vein; insert catheter at a 10−30∘10-30^\circ angle.
    4. Observe for blood flashback, advance the catheter, and secure with a transparent dressing.
  • Maintenance:
    • Assess every 4 hours or according to facility policy.
    • Flush with saline before and after medication administration.
    • Manage dressings to ensure they are clean, dry, and intact.
    • Monitor for complications like phlebitis, infiltration, and infection.
  • Removal:
    • Indicated when therapy is complete, complications arise, or 72−9672-96 hours have elapsed.
