Let's get started with the show. I'm just going to go through a couple of the lab values and how to remember them in this quick mnemonic. So the first thing is that we're going to go over this L that's in the periodic table. I took out beryllium so hydrogen lithium sodium potassium magnesium and calcium and then these guys are plus one and this is plus two that becomes really important later but knowing that these guys are all in the same column hydrogen lithium sodium potassium that will do well.

Alright so you probably never looked at it this way but hydrogen is the well it's the negative log of the hydronium concentration that's what you actually get with the pH but basically it's how acidic or basic it is your body is a little bit higher than seven which is neutral so 7.35 to 7.45 for the pH but if you look down at sodium if you make that seven into a one kind of straighten it up it turns into a 135 to 145 just like you got 7.35 to 7.45.

And then you can take that 35 from sodium and make the 3.5 from potassium to 0.5 or 2 5 ml equivalents per liter so just a quick way to kind of put the hydrogen the sodium and the potassium together but when we think about these lab values uh really it just comes down to some of the things I've heard in mnemonics I've come across so again hydrogen 7.5 to 7.45 looks a lot like the 135 to 145 mil equivalents per liter in sodium.

I've also seen that you underline the OD and sodium to make odd numbers so the first three odd numbers are one three and five and you just add 10. potassium 3.5 to 5 I've heard three to five bananas in a bunch and they're half off so the 3.525 lithium and serum creatinine you probably never put together before but 0.6 to 1.2 mil equivalents per liter would be lithium.

And if you want you can take that it its atomic number is three multiply by two to get the six and 0.6 and multiply that 0.6 again to get 1.2 uh serum creatinine though is 0.6 to 1.2 milligrams per deciliter magnesium you could have taken the one three from sodium but 1.3 to 2.1 and then calcium and chloride you probably never put together but the nine point zero to ten point five very similar to the ninety-five to one hundred five.

Though I've seen ninety-six to one hundred six for chloride as well but nine-one-one that's the calcium mnemonic so nine to ten point five if you round up and then I've heard ninety-five to one hundred five is a hot tub temperature but be careful the maximum is actually one hundred four.

Uh so Casino cratonin we talked about how that's next to lithium or similar to lithium at zero point six to one point two, the bun though if you put it right under it retains that six gets rid of the decimal and you double the twelve to get twenty-four.

So generally, I see six to twenty-four milligrams per deciliter but I've also seen the mnemonic where you've got bunions on your five toes and you got twenty digits total with your hands and your feet so five to twenty milligrams per deciliter for bun I've seen them both creatinine clearance so the sevens and eights.

So creatinine clearance ninety-seven to one hundred thirty-seven milliliters per minute is the sevens forty is the difference and for women creatinine clearance eighty-eight to one hundred twenty-eight uh milliliters per minute these are the eights they end in eight uh forty is the difference again.

So again, a quick review of some of the lab values that you really do need to know I just thought those mnemonics were really cool as always informations for informational purposes if you've got medical condition consult a medical professional thanks for listening to the memorizing pharmacology podcast.
