The 21-year-old opened the scoring for Malky Thomson’s side in the first-half before Sam Kerr, Chantelle Swaby and Lizzie Arnot added goals in the second-half.
Speaking to RangersTV after the match, she said: “It wasn't a pretty game but they were good defensively and we got the three points so we are happy about that.
“We showed patience and the subs made a really good impact when they came on and scored two goals and then we got one from Chantelle so we were patient and that was what we wanted.
“I am really happy to score my first goal this year and I hope I will score more but at the end of the day the most important thing is the win and now we are focussed on Sunday against Motherwell.”
With seven changes heading into this evening’s match, Bourma said the whole squad had a part to play.
She continued: “It was really important because in the first-half we played similar to them and it wasn't great so at half-time we spoke and said we need to play our own game and that is what we did in the second-half and we managed to score three more goals.
“It was a whole squad effort, it was great goals from Sam and Lizzie and we know we all have to have an impact, starters and the substitutes because we still need to reach a higher level.”
