Comprehensive Nursing Assessment and Clinical Critical Thinking Notes

Resources and Learning Strategies for Nursing Assessment

  • Textbook and Syllabus Requirements:     * The fundamental textbook was not listed on the syllabus to purchase, and students are not strictly required to have one for this specific section.     * Instructors emphasize that all necessary information will be covered in the lectures.     * Students should possess a "Med-Surg" (Medical-Surgical) book, even though it may not contain sections specifically dedicated to physical assessment.

  • Note Pages and PowerPoint Slides:     * Curriculum maps usually dictate specific page numbers to review, but these may be removed in favor of instructor-provided note pages.     * Instructors provide a "Physical Assessment Word Bank" within the note pages.     * Students are advised to print PowerPoint slides with the note pages visible (often found at the bottom of the screen in the software).

  • Audio Recording and Active Listening:     * Students are strongly encouraged to audio record lectures, as instructors may not provide transcripts or identical notes in every session.     * Recording allows students to stop, start, and transcribe notes at their own pace later.     * Permission Requirement: Students must obtain explicit permission from the instructor before recording any lecture.     * Some PowerPoint slides include a talking icon that provides extra reinforcement and specific audio for that slide's content.     * The instructor suggests that students learn more by "sitting back and listening" during the actual lecture rather than frantically writing, as they might miss critical exam details while focusing on transcribing words.

Fundamental Concepts of Assessment and Critical Thinking

  • Baseline Data and Trending:     * The primary purpose of a baseline assessment is to establish a starting point for "trends."     * Assessments help determine if a patient's condition is "trending up" or "trending down."     * Baseline data allows the nurse to know if a patient's status is improving or worsening.     * Nurses can supplement baseline data by asking patients for their "normal" values (e.g., "What is your normal temperature?" or "Do you know your normal blood pressure?").

  • Nursing Problems vs. Medical Problems:     * Current curriculum focuses on "Nursing Problems" rather than traditional "Nursing Diagnoses."     * While similar to medical problems, nursing problems describe the patient's human response to health conditions.

  • Health Screening as Secondary Prevention:     * Screening for health problems is always categorized as Secondary Prevention (e.g., the physical assessment required to enter a nursing program).

  • Critical Thinking for the Registered Nurse (RN):     * Higher-level critical thinking is a primary differentiator between an LPN and an RN.     * The Process: Suspect $\rightarrow$ Collect Data $\rightarrow$ Analyze Data $\rightarrow$ Plan.     * Example Scenario: A patient is shaky and diaphoretic (sweating).         * Suspect: Does this represent hypoglycemia (low blood sugar)?         * Broaden Thinking: Could it be an infection? Cancer? A drug reaction? Drug withdrawal? Side effects from a specific medication?         * Collect Data: Obtain vital signs or a BMP (Basic Metabolic Panel). Perform an immediate blood sugar check.         * History: Ask the patient if they have experienced these symptoms before (e.g., a patient might have taken too much thyroid medication in the past).         * Analyze: Use lab results to confirm or rule out the initial suspicion (e.g., "It wasn't low sugar after all, they have a fever").

  • Proactive vs. Reactive Care:     * Proactive: Identifying signs and symptoms ahead of the game to prevent a patient from "crashing."     * Reactive: Taking care of a problem after it has already manifested or caused harm (e.g., failing to catch sepsis until organ failure occurs).     * Failure to Rescue: This term refers to the failure to identify and prevent complications early enough. Nurses must stay on top of patient status to avoid this outcome.

Types of Physical Assessment

  • Comprehensive Head-to-Toe Assessment:     * An in-depth, complete review of every system working from top to bottom.     * The instructor uses the "Keith RN system" as an example.

  • Focused Assessment:     * Targeting one specific area based on the patient's complaint.     * Example: If a patient enters the ER with right-sided abdominal pain, the nurse focuses on the abdomen rather than eyes, ears, nose, or throat.

  • Ongoing Assessment:     * The constant reassessment of a known problem.     * Example: Regularly checking chronic pain levels or performing neurological checks (vitals and pupils every 30 minutes\text{vitals and pupils every } 30 \text{ minutes}) for head injuries.

Procedural Steps and Initial Actions

  • Preliminary Actions:     1. Introduce yourself.     2. Identify the patient using at least two identifiers (2−32-3 are preferred), such as Name and Date of Birth. Match these to the wristband.     3. Explain the procedure.     4. Gather supplies.     5. Wash hands.     6. Provide for privacy.

  • Preparing the Environment:     * Ensure the patient has used the bathroom (a full bladder may make abdominal palpation uncomfortable).     * Mute televisions and reduce loud noises to hear heart/lung sounds clearly.     * Adjust lighting; assessments cannot be done accurately in the dark.     * Arrange for an interpreter if cultural or language needs are identified.

  • Lifespan Considerations (Elderly):     * The target duration for a complete head-to-toe assessment is approximately 10 minutes10 \text{ minutes}.     * Assessments longer than 30 minutes30 \text{ minutes} can exhaust elderly patients.     * Avoid asking "Is it okay?" as patients may say no. Instead, use phrases like: "Mrs. Smith, I’ll be back in five minutes to do your assessment; it should take about 10−15 minutes10-15 \text{ minutes}."     * If a patient is too tired, allow them to rest and gather historical data through conversation before returning to the physical exam.

Data Collection and Classification

  • Objective vs. Subjective Data:     * Objective: Observable and measurable findings (e.g., blood pressure, rashes).     * Subjective: Information stated by the patient (e.g., pain, feelings of dizziness).

  • Primary vs. Secondary Data:     * Primary Objective: Observed and documented only by the Registered Nurse.     * Secondary Objective: Information from someone other than the RN (e.g., a lab technician or another provider).     * Primary Subjective: Statements made by the patient directly.     * Secondary Subjective: Statements made by family members or others about the patient.

  • Constant vs. Variable Data:     * Constant: Items that do not change (e.g., Blood Type, Race, Date of Birth).     * Variable: Items that change frequently (e.g., Vital signs, pain level, weight, height).

  • Risk Factors:     * Modifiable: Factors the patient can change (e.g., Diet, exercise, smoking habits).     * Non-modifiable: Factors that cannot be changed (e.g., Genetics, age, ethnicity).

Physical Assessment Techniques

  • Four Primary Techniques:     1. Inspection (Observation): Visual data gathered through sight.     2. Auscultation: Listening with or without a stethoscope.         * Direct Auscultation: Listening without a stethoscope (e.g., hearing labored breathing, a loud cough, or stomach gurgling).         * Indirect Auscultation: Listening with the aid of a stethoscope.     3. Percussion: Tapping on body parts to produce sounds that identify the density of underlying tissue.         * Direct Percussion: Tapping directly on the body (e.g., tapping the sinuses to check for tenderness).         * Indirect Percussion: Placing a finger (the third middle finger) on the body and tapping it with the other hand's third finger.         * Percussion Sounds:             * Dull: Heard over solid organs or bony areas.             * Tympanic (Timpany): Heard over air-filled structures (e.g., a puffed cheek or air bubble in the abdomen).             * Flat: Heard over extremely dense areas like bone.             * Method: To identify a full bladder without an ultrasound, percussion starts at the pubic symphysis and moves up until the sound changes.     4. Palpation: Using the hands to feel for texture, temperature, and masses.

  • Historical Context (Taste):     * The instructor noted that physicians in the early 20th20\text{th} century (like her father) sometimes tasted urine to detect sweetness as the only way to diagnose diabetes. This is no longer practiced.

Lifespan and Developmental Variations

  • Infants:     * Prioritize thermal regulation; ensure the infant is not placed on a cold surface that could "suck the heat out."     * Infants should be weighed "in their birthday suit" (naked) without a diaper to get an accurate weight.

  • Toddlers:     * Perform the least invasive procedures first and the most invasive last (e.g., checking ears/throat last).     * Praise the child and allow them to make small choices.

  • Preschoolers:     * Use "doll play" or objects. Perform the assessment on a doll first (e.g., taking a doll's temperature) to show it doesn't hurt.     * Involve the child in palpation by having them place their hand over yours to reduce ticklishness.

  • School-Age:     * Focus on building trust and allowing independence. Explain what you are doing with their bodies.

  • Adolescents:     * Privacy is paramount. When asking about sexual activity, recreational drug use, or suicidal ideation, separate the adolescent from the parent.     * Strategy: Take height and weight, then send the mom to the room ahead while you ask the sensitive questions privately.

  • Older Adults:     * SPICES Tool: Sleep disorders, Problems with eating/feeding, Incontinence, Confusion, Evidence of falls, Skin breakdown.     * Evaluate ADLs (Activities of Daily Living) such as the ability to feed themselves or walk to the bathroom. Check for sensory aids like glasses, hearing aids, and dentures.

Cultural and Safety Considerations

  • Cultural Evaluation:     * Check the chart for cultural needs before entering the room (e.g., preference for a same-sex provider or presence of family members).     * Recognize personal biases. If you cannot handle a situation objectively, seek assistance from another provider.     * Example Scenario: A Jehovah's Witness (referred to as "child’s witness" in transcript) may refuse blood products. The instructor mentions a case where a resident struggled to understand a family's refusal of life-saving blood for a teenager due to their religious beliefs.

  • Family Dynamics:     * Be aware of who makes decisions in the household (the "head of household").

  • Barriers to Care:     * Identify financial barriers (e.g., can the patient afford insulin?), lack of access, or mistrust of the healthcare system.

The 60-Second Situational Assessment

  • This is the first visual and sensory sweep when walking into a room.
  • Patient Safety:     * Check IV lines (ensure fluids like Heparin are running at the correct rate, follow the line from bag to patient).     * Check Oxygen (verify the flow rate on the wall matches the order, e.g., 2 Liters per nasal cannula2 \text{ Liters per nasal cannula}).     * Ensure the call bell is within reach and the patient has non-skid socks on.
  • Environmental Safety:     * Identify trash, needles, or spills on the floor.     * Check bed height and side rails.     * Watch for "cobwebs" or floor hazards that could cause a trip/fall.
  • Olfactory (Senses):     * Smell can identify specific issues: Pseudomonas has a distinct odor, and abscesses or urinary incontinence are often detectable by scent upon entry.

General Survey components

  • Appearance & Behavior: Assess if the patient looks their "age appropriate" years. Leathery skin from sun exposure can make someone look older. Note facial expressions and mood (e.g., "flat affect" means no expression).
  • Body Type & Posture: Note if the patient is sitting straight or slumped. Identify stature (large vs. small).
  • Speech: Assess if it is appropriate for age or indicates a developmental delay. Note speed, volume, and clarity.
  • Gait: Observe the patient's walk for steadiness or loss of balance.
  • Mental Status:     * Level of Consciousness: Oriented ×3\times 3 or ×4\times 4.     * Oriented ×3\times 3: Person, Place, Time.     * Oriented ×4\times 4: Person, Place, Time, and Situation (some use this to mean they know the doctor or current events).     * Glasgow Coma Scale: Used for standardized neurological assessment.
  • Body Mass Index (BMI):     * Nurses do not need to calculate the formula manually, but must know the thresholds:         * Overweight/Moderate Obesity (Level 1): BMI between 30 and 35BMI \text{ between } 30 \text{ and } 35         * Severe Obesity: 35 to 4035 \text{ to } 40         * Morbid/Severe Obesity: >40> 40
  • Measurements for Children:     * Use height/weight charts to plot percentiles.     * Head Circumference: Required for children less than 2 years old2 \text{ years old}. Measured above the ears.     * Length: For children under 2, lay them flat on a table, mark the head and the stretched-out foot on the paper, then measure the distance between marks.
  • Vision Check:     * Use alphabet charts, directional E charts, or kindergarten charts (pictures).     * When testing, use a paper cup to cover the eye rather than a hand to prevent the patient from pressing on the globe and blurring their vision for the next eye.     * Ishihara Test: Used for colorblindness.

Clinical Findings and Documentation

  • Objective Documentation: Phrases like "clean-shaven," "oxygen in place," and "IV line present" are used.
  • Safety Warning (Fistula): Never ignore patient warnings regarding specific limbs. The instructor shared an example of a student who performed a blood pressure/draw on an arm with a fistula despite patient warnings, resulting in a lawsuit and dismissal from the program.
  • Medical Terminology (Eyes):     * Anicteric: Normal; without yellowing of the sclera (white of the eye).     * Icteric: Abnormal; yellowing of the sclera (indicative of jaundice).

Questions & Discussion

  • Question (Audience): How many identifiers should be used?
  • Response (Instructor): Two is sufficient (usually name and date of birth), but three is even better. Always match them to the wristband.
  • Question (Audience): What if a patient refuses an assessment?
  • Response (Instructor): Students should explain the rationale. Explain that a head-to-toe assessment is a baseline to detect changes over an 8 or 12-hour shift. Many patients will change their minds once they understand the purpose.
  • Question (Audience): (On percussion sounds over bone).
  • Response (Instructor): Tapping bone produces a "flat" or "dull" sound, whereas the cheek produces "tympany."
  • Question (Audience): Is there help for Mac users with software?
  • Response (Instructor): IT is available during the day to help with ExamSoft or Kaplan downloads, though they are not present at night.
  • Clarification: The instructor emphasizes knowing why signs and symptoms are occurring (the pathophysiology) rather than just memorizing labels.
