A goniometer is used: A At the scene of a crime to collect evidence B B To measure a patient's cholesterol C To measure a patient's range of motion D To check a patient's blood pressure

## Step 1<br />A goniometer is a device used in physical therapy and orthopedic medicine to measure the range of motion around a joint. It is not used for collecting evidence at crime scenes, measuring cholesterol, or checking blood pressure.<br /><br />## Step 2<br />Option A suggests that a goniometer is used at the scene of a crime to collect evidence. This is incorrect. Crime scene investigators use various tools to collect evidence, but a goniometer is not one of them.<br /><br />## Step 3<br />Option B suggests that a goniometer is used to measure a patient's cholesterol. This is also incorrect. Cholesterol levels are measured using blood tests, not a goniometer.<br /><br />## Step 4<br />Option C suggests that a goniometer is used to measure a patient's range of motion. This is correct. A goniometer is used to measure the range of motion around a joint, which is crucial in diagnosing joint problems and planning rehabilitation exercises.<br /><br />## Step 5<br />Option D suggests that a goniometer is used to check a patient's blood pressure. This is incorrect. Blood pressure is measured using a sphygmomanometer, not a goniometer.
