00:01
And here's more
of the fun part.
00:03
We get to apply it
to patient care.
00:05
I love that when we give you
some information,
and then let you apply it
to what you'll see
in the clinical setting.
00:10
So Ms. Hydrashun's,
urine specific gravity result
is 1.035.
00:17
Anytime you see a value,
what do you ask yourself?
Is it high? Is it low?
Is it normal?
Well, this, yeah.
That's high.
00:25
Now what does that mean, right?
What does a urine specific gravity
that is high mean?
Could this indicate dehydration?
Yeah, you know that it does.
00:37
The more dehydrated a patient is
you're going to see that
urine specific gravity number
get bigger,
it's going to move towards 1.030
and higher.
00:49
Ms. Dehydration is definitely higher
than 1.030.
00:54
Now the next couple questions
are a review.
00:56
So you should know these answers,
if you don't, no problem.
00:59
You just don't know them yet.
01:02
But let me see
if you can answer these.
01:04
What would you expect
her blood pressure to be
compared to her
normal blood pressure?
Talking about Ms. Hydrashun,
the only other piece of
information you have
is a urine specific gravity
of 1.035.
01:19
Right, she is dehydrated.
01:21
That means she has less volume
in her intravascular space.
01:24
We would expect her blood pressure
to be lower than normal for her.
01:29
Next question,
what would you expect her heart rate
to be compared to her normal?
Right.
01:37
High.
01:37
Because when blood pressure drops,
the body compensates
by raising the heart rate
as long as it can sustain
that heart rate
over a period of time.
01:46
All right, good deal.
01:47
Now these are the
types of questions
you want to make sure
are clear in your mind
to make sure you understand
the concepts
and you're likely to see
this kind of content on an exam.
01:58
Now, what does urine look like
when a patient is dehydrated?
We have four -- count them,
four beautiful bladders
for you up there.
02:05
Now which one do you think
is going to look like
urine specific gravity
that's pretty high?
Yes.
02:12
Are you going to be on the
lighter end or the darker end?
Yes, you're going to be
moving toward
like more concentrated
darker urine
for a patient that's dehydrated.
02:22
Now their urine specific gravity
will be higher,
but you can visually
look at your patient's urine
and get a good idea
if they're dehydrated.
02:30
You can even look at your own urine
and see if you're dehydrated.
02:35
Now it's better to look at
a sample in a cup
rather than what you deposit
in a toilet bowl,
but the concept is the same.
02:41
The darker it is usually the more
dehydrated it is.
02:45
We've got transparent to pale straw
on one end,
all the way up to severe dehydration
on the other end.
02:52
Remember, it's a spectrum.
02:54
You can't just look at the
color of a urine
and determine the
urine specific gravity number
but you can get a good idea
if the patient is well hydrated
or is
extremely dehydrated.
