Palpate each of the following soft tissue landmarks you described in step 2 of the Pre-Lab Review. After successfully palpating each, individually identify the landmark on the patient using its corresponding letter with either an adhesive sticker or surgical skin marker. If specified by your instructor, take a photograph of each labeled region for grading. Record your progress in the chart in the Results section of this activity. HINT If you are using adhesive stickers, write the letters prior to placing them on your partner. This will save time, result in easier-to-read letters, and potentially avoid injuring your partner by exerting excess pressure. 5. After completing each palpation and marking them on your partner, switch roles and repeat, taking photographs if required. Be sure to document your progress in the Results section. 6. Depending on the directions provided by your instructor, submit photographic evidence of your results or be prepared to complete an in-person demonstration of your palpation skills. 7. If you used a surgical marking pen, use the gentle soap or baby wipes to clean up the marks. Results As you successfully palpate each landmark, check it off in the chart to keep track of your progress. Landmark Identification Landmark Clinician 1 Clinician 2 A. Temporalis muscle □ □ B.
