On the following page of our game guide to Wasteland 3, you can find a detailed description of the Top Doc side mission. This walkthrough will allow you to complete the task without any impediments.
Note: Although the task is classified as side quest, its completion is required to complete the Full House main mission.
- Find the supplies and deliver them to Doc Parker.
The mission can be activated at the Arapaho Iron Thunder Garage in the Downtown of Colorado Springs. Doc Parker is there - talk to him and he'll ask you to find some medical supplies. List of desired items includes Medic Pack, Suture Kit and Injury Kit.
You can find Medic Pack in any medical crate. In the case of Suture Kits and Injury Kits, it's also quite easy to get those items. You will find them in one of the crates that is opposite the exit from the garage.
Once you've collected the items you need, go back to the doctor and talk to him. He will ask you to use the collected items to treat patients. To complete the task, you must use the following medical supplies on the wounded people:
-  Suture Kit
-  Medic Pack
-  Injury Kit
Finally, talk to Doc Parker. When he finds out that you have helped the patients, you will be able to hire him at the Ranger HQ. He will move the most seriously injured patient to the Ranger HQ and become a Doctor of that base.
