LPN ATI Exam Study Guide

LPN ATI Exam Study Guide Notes

Patient Safety Fundamentals

  • Core Principles: Focus on preventing injury to:
    • The patient
    • The nurse
    • Other healthcare staff
Safety Strategies
  • In Hospitals and Home:
    • Keep bed in lowest position
    • Lock wheels on beds and wheelchairs
    • Ensure call light is within reach
    • Remove clutter and hazards
    • Use non-skid footwear
Proper Body Mechanics
  • Techniques:
    • Bend at knees, not waist
    • Keep back straight
    • Keep patient close to your body
    • Avoid twisting
    • Use assistive devices when needed
If a Patient Falls
  • Do Not try to catch them.
  • Instead:
    1. Stay with patient
    2. Ease them gently to the floor
    3. Protect the head
    4. Call for help
    5. Assess injuries
    6. Document and report
  • ATI Tip: Trying to catch them can cause nurse injury.

Assistive Devices and Mobility

Types of Gaits

  1. Two-point gait: Sequence of movements as follows:

    • Right Crutches (RC)
    • Right Leg (RL)
    • Repeat the sequence with Left Crutches (LC) and Left Leg (LL).

  2. Three-point gait: Sequence includes:

    • Move crutches (RC)
    • Move weak leg (RL)
    • Move strong leg (RL)

  3. Four-point gait: Follow a similar routine but using each extremity in a staggered sequence.

Gait Belts
  • Purpose:
    • Prevent falls
    • Provide a safe grip
  • Placement:
    • Around waist, snug but not tight
    • Never use under arms.
Walkers
  • Use for:
    • Maximum stability
  • Key ATI fact: Cannot be used on stairs.
Walker Gait Sequence
  1. Move walker forward
  2. Move weak leg forward
  3. Move strong leg forward
Canes
  • Rule: Cane goes on the STRONG side.
  • Sequence:
    1. Cane forward
    2. Weak leg forward
    3. Strong leg forward
Crutches — Swing-Through Method
  • Used when: Patient can bear weight on arms.
  • Sequence:
    1. Crutches forward
    2. Both legs swing past crutches.

Pressure Ulcers

  • Extremely Important ATI Topic
Stages of Pressure Ulcers

  1. Stage 1:

    • Skin intact
    • Redness
    • Does NOT blanch
    • Painful
    • ATI clue: Skin is still intact.

  2. Stage 2:

    • Partial thickness loss
    • Blister or shallow open wound.

  3. Stage 3:

    • Full thickness skin loss
    • Fat visible
    • Deep crater
    • No muscle or bone visible.
    • ATI exam favorite

  4. Stage 4:

    • Muscle, tendon, or bone visible
    • Severe damage.
Prevention Strategies
  • Recommended Actions:
    • Turn patient every 2 hours.
    • Use pillows, foam pads, and air mattresses.
    • Keep skin clean and dry.
    • Nutrition: Focus on protein and fluids.
Treatment
  • Actions:
    • Clean wound
    • Dress wound properly
    • Relieve pressure
    • Monitor for infection.

Vital Signs Assessment

  • Components to Know Normal Ranges:
    • Temperature: 97.8–99°F
    • Pulse: 60–100 bpm
    • Respirations: 12–20
    • Blood Pressure: approximately 120/80 mmHg
    • Oxygen Saturation: 95–100%.
Temperature Timing Rule
  • Wait 15–30 minutes after:
    • Eating
    • Drinking
    • Smoking
  • Otherwise the reading may be inaccurate.
Troubleshooting Abnormal Vitals
  • Example ATI Question: If O2 saturation = 88%, actions to take:
    • Sit patient upright
    • Provide oxygen
    • Notify RN/provider.

Respiratory Assessment

Normal Lung Sounds
  • Clear and unobstructed.
Abnormal Lung Sounds (ATI FAVORITE)

  1. Crackles:

    • Sound: Popping
    • Cause: Fluid in lungs
    • Seen in conditions such as heart failure or pneumonia.

  2. Wheezing:

    • Sound: High-pitched
    • Cause: Airway narrowing
    • Seen in asthma or COPD.

  3. Rhonchi:

    • Sound: Coarse, snoring
    • Cause: Secretions.
Respiratory Distress Signs (ATI Exam Critical)
  • Signs include:
    • Rapid breathing
    • Use of accessory muscles
    • Nasal flaring
    • Cyanosis
    • Low O2 saturation.
Priority Interventions
  • FIRST ACTION: Sit patient upright to improve lung expansion.

Oxygen Delivery Devices

  • Know the following:
    • Nasal Cannula: Most common, delivers low oxygen.
    • Face Mask: Higher oxygen delivery than nasal cannula.
    • Non-Rebreather Mask: Delivers highest oxygen level without intubation, for emergency use.
    • Incentive Spirometer: Purpose to prevent pneumonia; patient instructions:
    • Inhale slowly
    • Hold breath
    • Repeat 10 times/hour.
    • K-Box Device: Used for oxygen delivery or respiratory therapy—follow facility protocol.

COPD Care

ATI Priorities
  • Positioning: Sit upright; best positions include:
    • High Fowler's
    • Tripod position.
  • Oxygen Use: COPD patients need controlled oxygen as too much can suppress breathing.
Breathing Techniques
  • Pursed-lip breathing: Improves oxygen exchange.

Nutrition and Diet

Types of Diets
  1. Clear Liquid Diet: Includes water, broth, tea, and gelatin (not milk).
  2. Full Liquid Diet: Includes milk, soup, ice cream, and pudding.
  3. Regular Diet: Normal food.
Feeding Tubes (PEG / G-Tube)

Medication Administration Rules (ATI Exam Critical)

  • Flush Protocol:
    • Before medication
    • Between medications
    • After medication
  • Flush amount: 15-30 mL water.
Multiple Medications
  • Administration Guidelines:
    • Give ONE medication at a time.
    • Never mix medications together.
Prevent Aspiration
  • Keep patient upright: 30–45 degrees.

Medication Administration Safety Principles

  • Follow the 6 Rights:
    1. Right patient
    2. Right medication
    3. Right dose
    4. Right route
    5. Right time
    6. Right documentation.

Dosage Calculations (10 Questions on ATI Exam)

  • Formula for Calculating Dosage:
    Desired/Have×Quantity\text{Desired} / \text{Have} \times \text{Quantity}
  • Example Calculation:
    • Order: 500 mg; Have: 250 mg tablets
    • Calculation: (500/250)=2(500 / 250) = 2 tablets.
  • Example Liquid Calculation:
    • Order: 10 mg; Have: 5 mg per mL
    • Calculation: (10/5)=2(10 / 5) = 2 mL.

ATI PRIORITY INTERVENTIONS (Critical Thinking)

  • ATI questions often ask: "What is the FIRST action?" Always choose:
    1. Airway
    2. Breathing
    3. Circulation
    4. Safety
  • Example: Patient short of breath → Sit upright FIRST.

MOST IMPORTANT ATI EXAM TOPICS (High Probability)

  • Memorize these completely:
    • Pressure ulcer stages
    • Lung sounds
    • Respiratory distress interventions
    • Vital signs normal ranges
    • Feeding tube medication flushing
    • Assistive devices usage
    • Patient fall safety
    • Oxygen delivery devices
    • COPD positioning
    • Dosage calculations.

Practice ATI-Style Questions

  • Example Questions and Answers:
    1. Patient has wheezing. What does this indicate?
    • Answer: Airway obstruction.
    1. Patient begins to fall. What should nurse do?
    • Answer: Ease patient to floor.

    • Answer: Redness, skin intact.
    1. First action for breathing difficulty?
    • Answer: Sit patient upright.
    1. PEG tube medication administration?
    • Answer: Flush before and after each medication.

Final ATI Exam Strategy

  • Before exam:
    • Memorize:
    • Pressure ulcer stages
    • Lung sounds
    • Vital sign ranges
    • Feeding tube flushing
    • Safety interventions.
    • Practice:
    • Dosage calculations
    • ATI questions.
    • Think: Safety first, Airway first, Positioning first.
