-What % IBW is LK?

Quizplus · Accepted Answer

To calculate LK's % IBW, we need to first calculate her IBW. Using the formula for IBW for females, which is 100 lb for the first 5 feet of height plus 5 lb for each additional inch, we get:

100 lb + (4 x 5 lb) = 120 lb

Then we can calculate her % IBW using her actual weight:

(IBW / actual weight) x 100 = (% IBW)
(120 / 170) x 100 = 70.6%

Therefore, LK's % IBW is 70.6%, which is closest to answer choice C, 133%.

As for the best choice(s) for addressing LK's persistent diarrhea, we do not have enough information to make a recommendation. It could be related to her recent surgery or to her diet, and further assessment would be needed to determine the cause and appropriate intervention.
