Trina has posted lots of good stuff on this blog for Nursing 7, including the link to an explanation of the RAAS on Wikipedia. It was so helpful to me, I thought I should repost it, closer to the top... Check it out at this link... Renin-Angiotensin-Aldosterone System. (Thanks, Trina!)
Note: the author's starting point on the diagram is a decrease in renal perfusion, but -- in his/her notes -- points out there are other ways RAAS can be activated -- "...by a low NaCl concentration in the macula densa or by sympathetic activation."
Be sure to scroll down for all the Nursing 7-related information. There are lots of other good posts by Trina and others, like Bonnie's links to information on hemodynamic basics or links to videos to refresh your clinical skills, next to the Starbucks IV bag below. Drink it up, y'all!
Nursing 7 is the perfect time to reacquaint yoursef with (or introduce) the information available on Bonnie Boss' "original" student blog she created for fellow SJDC nursing students. In addition to her excellent test bank, bringing us tons of NCLEX practice, she includes many links to supplementary information on a variety of relevant topics under "practice tests and quizzes" and "helpful links." Get to know what's out there. Bonnie's already done a lot of the legwork for us.
(Muchas gracias, Bonnie!)
FYI, Bonnie's now a full-time RN working in ICU at Lodi Memorial.
