Hi, I'm Meris. And in this video, we're going to be talking about bladder scanners and different
types of urinary catheters and important considerations for them. I'm going to be
following along using our Fundamentals of Nursing flashcards. These are available on our website,
leveluprn.com. But if you already have your own, I'd invite you to follow along with me. I'm
starting on card number 120. Let's get started. So before we start, I wanted to tell you that if you
stay until the end, I'm going to tell you a really important piece of advice that my fundamental
skills professor taught me when I was in nursing school that I want to pass along to you.
So let's go ahead and talk about bladder scanners. As you can see here on this card, we do have a
step-by-step list of how to use a bladder scanner. I'll let you look at that in your own time. But
the most important thing that I want to get across to you is, why do we use a bladder scanner? So the
bladder scanner uses ultrasonography to assess how much fluid, how much urine, is in a patient's
bladder. So this can help us diagnose things like urinary retention or if they're having a
large post-void residual. The big, bold, red stuff here on this card is telling you about
the placement of the transducer. You want to make sure that it is above the pubic symphysis
because we're not trying to scan bone, so about one inch above that and point it down towards the
bladder. Another thing I want to point out is to make sure that you use the button on the machine
to select whether or not your patient has a uterus because this changes how the machine calculates or
what it looks for. So be sure to think about that when you're using a bladder scanner.
All right. So now, let's talk about different types of urinary catheters.
Here on card 121 we talk about the difference between an indwelling catheter and a straight or
intermittent catheter. So indwelling is what the name suggests. It stays in. That's where it dwells
for a while. So you might hear this called a Foley catheter sometimes, but Foley is actually
a brand name. So indwelling catheters is what you should be calling it in nursing school. So this is
really helpful for patients who have things like the need for really strict intake and output,
things like cardiac problems, heart failure, a patient who's comatose, all of those different
indications. But what's your biggest concern when you think about a patient with an indwelling
catheter? What's your biggest concern? Pause the video and think about it. I hope you paused it.
If you did, it should be a catheter-associated UTI. The longer an external device is inside
your patient, the more likely they are to get an infection. You're creating a bridge from the
outside to the inside, so this puts your patient at risk for a CAUTI, catheter-associated UTI.
Now, a straight or intermittent catheter, again, what it sounds like. It goes straight in and back
out, so it doesn't stay in there. This is much skinnier, much shorter duration of use. And
usually, this is used to get a sterile specimen or to treat a patient's urinary retention with
the hopes that they're going to be able to void after the urgent acute retention is relieved. Now,
if you look on card 122, we talk about two other types of catheters. I'm not going to go super
in-depth into these. I'll let you look into them in your own time, but this is suprapubic,
so meaning above the pubic bone. Supra is above and external, meaning not inside your patient.
So suprapubic catheters are going to be placed surgically. They go through the skin, so a big,
big risk for infection. External catheter's really great at decreasing the risk of infection. But
now if I have my skin possibly sitting in moisture for a prolonged period of time, what am I at risk
for? Pause the video and think about it. I'm at risk for skin breakdown especially with what we
call a condom catheter. There are also external devices such as wicking devices for a patient
who does not have a penis. So these actually are connected to suction, and they actively
remove the urine as it is expelled from the body. All right. This card 123 is one that I would say
really, really focus and spend your time on. This has to do with the care of an indwelling
urinary catheter. So a lot of important stuff to know, such as when we put it in, we use sterile
technique, not clean technique, sterile. The bag should always hang below the level of the bladder,
and we want it to be on the bed frame. We want to check for any kinks in the tubing. And we always
want to make sure that we don't have any dependent loops. Dependent means affected by gravity,
so any loops where we can't get the urine to go into the bag. Because basically, if I have a loop,
the urine from the patient is going to have to have enough force to go around the loop to get
into the bag. We don't want that because now we're at risk for urine backflowing into our patient
and, again, infection. Other things to know is that we need to remove these catheters as
soon as appropriate. So as the nurse, your job is to be your patient's best advocate.
You need to advocate to remove an indwelling catheter as soon as it is appropriate to decrease
your patient's risk for infection. Be sure to look over the other important points on that card,
but those are definitely the highlights. All right. So that is it for our review of bladder
scanners and urinary catheters. I hope it was helpful. If it was, please, go ahead and like the
video. And I would love to hear any advice or tips or ways to remember things that you might have.

You want to be the first to know when our new videos come out. Next up, we're going
to be talking about constipation, diarrhea, and ostomies. Thanks so much, and see you next time.
Okay. So when I was in fundamental skills, my professor told me
that you don't have to empty the Foley drainage bag before removing it. You can remove the Foley
first and then empty the drainage bag. But she told me that it's her experience and her best
advice that you should always drain the bag first before removing the catheter. Because one time,
she removed the catheter then went to empty the bag, and the catheter flopped down and hit her
in the face. So immediately, that was seared into my memory for the rest of my life. I will never
remove a Foley without emptying the bag first, so that way, you empty it. You can measure it. And
then you remove the Foley and put it immediately in the disposal. You don't want to be touching
that anymore. You don't want it resting on the bed. So maybe that helps you. But if you have
any other really good advice, I want to hear it. I invite you to subscribe to our channel and share
