21- RENAL NCLEX Questions You MUST Know Before Exam Day! 💯

[00:00:00]Which assessment finding is the most accurate indicator of fluid retention in a patient with renal failure?

[00:00:07]We need to keep two things in mind here.

[00:00:09]Our patient has renal failure and they are experiencing fluid retention, but the question asks for the most accurate indicator. This means when fluid retention occurs in a renal failure patient, what's the most common indicator that tells us the patient is retaining fluid? First is blood pressure.

[00:00:31]Blood pressure might change if there's fluid retention, but this isn't the most reliable indicator. So, this option is incorrect. Second is pulse rate.

[00:00:43]Pulse rate changes, but it's not the most reliable.

[00:00:47]A pulse rate change could be due to other reasons. For example, if a patient has hypovolemia, tachycardia will occur.

[00:00:55]Or if the patient is stressed, tachycardia occurs. Or if they're in pain, tachycardia also occurs. This means the change in pulse rate could be due to a different reason entirely. So, this isn't the most reliable indicator, either. The question asks for the most accurate, meaning most reliable. So, we can't trust this, either, as it could be due to other factors.

[00:01:18]This means this is also wrong.

[00:01:21]Next is the daily weight option, which is the most important, reliable indicator when there's fluid retention.

[00:01:29]Because in kidney patients, the kidneys' main job is to remove metabolic waste products like urea and creatinine.

[00:01:36]Besides that, it maintains fluid balance.

[00:01:39]When urine is excreted, it means fluid is being filtered and removed from the body. But when kidney failure occurs, this function becomes impaired. This means the kidney can't remove the fluid, so it gets retained inside the body. But how will we know? The most reliable indicator is daily weight. You make it a point to weigh the patient every single day, making sure to do this at the same time each morning to keep our measurements as accurate and consistent as possible. In clinical practice, it is generally believed that if a patient's weight increases by about 1 kg within a 24-hour period, we can reasonably assume that the patient is retaining approximately 1 L of water in their body. This is because 1 L of water weighs roughly 1 kg, so a sudden increase in weight is often due to fluid retention rather than other causes.

[00:02:25]Among all the available ways to check for fluid retention in patients, monitoring daily weight changes is considered the most reliable and trustworthy indicator, as it provides clear and objective evidence that can help guide patient care. It happens. So, that's why the patient's weight must be monitored daily. We should use the same scale for weighing and at the same time, and along with that, the patient's daily weight. This means the correct answer here will be daily weight.
