A nurse aide is measuring a resident's height using a standing scale with a height rod. To ensure an accurate measurement, the nurse aide should instruct the resident to:
- AStand straight with their heels together and look straight ahead.
- BLean slightly forward to reach the measurement rod.
- CStand with their back to the rod, arms folded.
- DLook down at their feet.
Show answer & explanationAnswer & explanation
Correct answer: A. Stand straight with their heels together and look straight ahead.
For an accurate standing height measurement, the resident should stand tall, heels together, back straight, and look straight ahead. This ensures they are in a neutral, fully extended position, preventing underestimation or overestimation of height.
Why the other options are wrong
- B. Leaning forward will result in an inaccurate, shorter measurement.
- C. While standing with their back to the rod is correct, folded arms do not guarantee proper posture for height.
- D. Looking down will cause the head to tilt, resulting in an inaccurate, shorter measurement.
Accurate Standing Height Measurement
The proper technique for measuring a person's height using a standing scale with a height rod to ensure precision.
- Resident stands straight, heels together
- Back against the rod (if applicable)
- Head in neutral position, looking straight ahead
- Shoes off
- Lower height rod to rest gently on top of head
Memory trick: Stand Tall, Look Straight, Feet Together, Get it Right!
