The participant will undergo the standard clinic exam in standardized order. The participants will complete the Hospital Anxiety and Depression Survey (HADS) at baseline. The HADS is reliable instrument for detecting states of depression and anxiety in the setting of a hospital medical outpatient clinic; it is available in English and Spanish versions. This will be used to establish their baseline anxiety levels. Participants will then be asked to rate their level of anxiety and pain immediately before beginning the exam, immediately after catheter placement, and 15 min after termination of the study using a 10 point visual analogue scale and the Wong-Baker pain scale.
