I believe nasagot na ni Mikeru22,brrr and soaring eagle ang karamihan sa questions mo.

Available ang Udan sa National Bookstore. 400+ ata ang book if I am not mistaken. Sayang talaga na I just discovered Udan noong nagrereview na ako. It would have been a big help sana during my college days.
Regarding the IMCI book, no need to buy na kung meron ka naman. Yung sa maternal book, ok naman siya because outline form and I can use the book if ever I decide to take the Midwifery exam.
RCAP is a compilation of old board exam questionnaires. I bought it online and sobrang kapal nung book, hehe. Sa sobrang kapal, di ko nasagutan lahat!

In fairness, may lumabas na 3 questions galing dun. Not the exact question but similar in nature.
For psychiatric nursing, I just used my psych book and handouts. Then I also downloaded some psych notes on the internet. Nagfocus lang ako sa mga basic psych concepts. I did the same with Community Nursing= own book + download community notes formula
Tama si Mikeru. Buy what you need lang kasi kung madami kang bibilhin, sayang lang kung hindi mo magagamit.
