Accurately measuring and recording a resident’s height is a fundamental CNA skill that ensures proper medical documentation, correct medication dosing, and effective care planning. While height typically does not change after adulthood, correct measurement is essential upon admission and during periodic health assessments.
Why Measuring Height Matters
- Provides baseline data for medical records
- Supports nutritional and medication calculations
- Helps track growth, weight changes, or posture-related conditions
- Ensures accurate BMI calculation
Supplies Needed
- Upright scale with height rod (stadiometer)
- Non-slip footwear for resident
- Privacy curtain or room for confidentiality
- Recording sheet or electronic health record access
Pre-Procedure Steps
- Knock on the resident’s door and introduce yourself
- Perform hand hygiene
- Explain the procedure clearly to the resident
- Ensure privacy by closing curtains or doors
- Confirm the resident can stand safely or determine if alternative measurement is needed
Tip: Residents who cannot stand should have their height measured while lying in bed using a tape measure, following facility guidelines.
Procedure for Measuring Height on an Upright Scale
Step 1: Prepare the Scale
- Ensure the scale is on a level surface
- Verify the height rod is set at zero
- Make sure the platform is clear
Step 2: Position the Resident
- Ask the resident to remove shoes and bulky clothing
- Have them stand upright with heels together, back straight, and eyes forward
- Feet should be flat on the scale platform
- Arms should hang naturally at the sides
Step 3: Align the Headpiece
- Lower the stadiometer headpiece until it rests firmly on the top of the head
- Ensure the resident’s heels, buttocks, and shoulders maintain contact with the backboard if available
Step 4: Read and Record Measurement
- Read the height in inches or centimeters according to facility policy
- Record the measurement accurately in the medical record
Alternative Measurement for Non-Ambulatory Residents
- Use a tape measure to measure from head to heels while the resident lies flat in bed
- Ensure body is aligned and flat on the bed
- Document the measurement clearly in inches or centimeters
Post-Procedure Steps
- Assist the resident to sit or move safely off the scale
- Return the scale to a safe, clean position
- Perform hand hygiene
- Document the height in the medical record, noting the measurement method
Pro Tip: Accurate height documentation supports proper medication dosing, nutritional planning, and monitoring of health trends over time.
CNA Tips for Accurate Height Measurement
- Always explain the procedure to reduce resident anxiety
- Maintain correct body alignment for the resident
- Ensure eyes, heels, and back are positioned correctly
- Repeat the measurement if resident shifts or posture is off
