Frequently Asked Questions

What should be reported to the nurse regarding body mechanics?
For body mechanics: Fall risk factors: history of falls, medications (sedatives, diuretics), mobility impairment, cognitive decline. I and O (intake and output): measure and record all fluids consumed and excreted in mL. Weight changes: report gain/loss of 2+ lbs in a day or 5+ lbs in a week.
How should a CNA communicate about body mechanics?
For body mechanics: Active listening: face the resident, maintain eye contact, nod, paraphrase. Therapeutic silence: allow time for the resident to process and respond. For cognitively impaired: use simple sentences, one instruction at a time, consistent routine.
What body mechanics should be used when performing body mechanics?
For body mechanics: Use mechanical lifts for residents who cannot bear weight. Bend at the knees and hips, not at the waist. Tighten core muscles before lifting.
