During climb out departing at approximately 4;500 feet; the number two engine oil quantity decreased to zero. Shortly after; the oil pressure also plunged to zero. The associated Low Oil Pressure light illuminated; and we proceeded to the QRH; referencing the Low Oil Pressure Procedure; and then the Engine Shutdown Procedure. We notified ATC of the problem; and requested vectors for a return to [departure airport]; as well as requested Fire Rescue to be notified. Fuel and souls onboard were given to ATC. The Flight Attendant (FA) were notified and briefed. The Passengers were briefed on the reason for the return.Ground Ops was notified; and asked to relay a message to Dispatch of the circumstances. The flight plan was amended at (time) for the return to the departure airport. All QRH procedures were followed to completion; to the best of our ability. The [flight computer] was used to run flaps 15; single engine; landing dry runway. Landing weight was approximately 124;000 pounds; maximum landing gross weight for our aircraft was 128;000 pounds. Thus overweight conditions were not a factor. Only one item was omitted by accident. Due to the high task loading; there was the failure to [notify] ATC. I simply got busy and forgot.I do believe ATC was under the assumption that we were an aircraft [in distress]; as they provided expedited service in every manner. After landing we proceeded to the large ramp just off of the Runway; and had Airport Fire Rescue inspect the number two engine for abnormal signs of debris or high heat signatures. None were found; so we proceeded to the gate. The entire Crew did a professional job of taking care of this situation. The Passengers seemed to be of normal conditions as they exited the aircraft.

A B737-700 lost oil quantity and pressure shortly after takeoff. The crew followed the QRH; shut the engine down and returned to the departure airport for an uneventful single engine landing.
