00:00 We know that urine specific gravity, the more dehydrated a patient is, the higher the specific gravity number will be. 00:08 So were you able to remember that normal is this value? Did you recognize when we say, a higher specific gravity number, it would be moving towards 0.30 or past it. 00:20 Okay, those are really important concepts. 00:22 So dehydration, - look, wait a minute, 1.025 is still within normal range. 00:29 Yeah, it is. 00:30 But you're definitely moving towards with pretty severe dehydration. 00:34 So when you see this number, remember that it's a spectrum. 00:38 It's not like 1.29 is fine. 00:41 1.31 is, Whoo! danger Will Robinson. 00:44 You have to know that this is a spectrum. 00:46 Certain patients are going to be impacted by dehydration more than others. 00:51 So know that, as my patient is becoming dehydrated, that number gets higher. 00:57 Yes, it's still within normal range, but that means they should respond fairly quickly to volume replacement. 01:04 Now severe dehydration is past that number of 1.030. 01:10 Now the quick quiz, if I'm severely dehydrated, if I have a urine specific gravity of 1.35, is my blood pressure high or low? Right, low. 01:18 Is my heart rate high or low? Right, high. 01:22 Make sure you have that concept solid, so you can recognize it in a clinical setting.
The lecture High Urine Specific Gravity: Dehydration (Nursing) by Rhonda Lawes, PhD, RN is from the course Urine Specific Gravity – Urinalysis (Nursing).
A client has a heart rate of 142 bpm and blood pressure of 84/56. What urine specific gravity result would correspond with this data?
