What is the first precaution before performing modified PROM for the knee and ankle?

• A. Warn about possible pain
• B. Gloves on
• C. Supports under knee + ankle = 3x along bed
• D. Supports under ankle + foot = 3x dorsiflex

Answer: (A)

Before doing modified PROM for the knee and ankle, tell the resident what to expect and warn about possible pain. This helps the person understand what will happen, gives them a chance to voice discomfort, and allows you to proceed safely or stop if needed. It also reduces surprise or resistance and supports their consent and comfort. After this heads-up, you would carry out the usual precautions like using gloves for hygiene and properly supporting the limb to protect the joints during movement. The positioning (supporting under the knee and ankle, or under the ankle and foot for dorsiflex) is important for safety, but the first step is communicating about pain so the resident can participate safely and report any distress.
