How do dextrose 50-50 decrease the potassium level in renal failure?
i am caring for a patient with an increased creatinine level of 2000 and a potassium level of 7.83, the pt is a candidate for a stat dialysis, for the meantime the dr ordered for a calcium gluconate via iv bolus then several doses of d50-50 to lessen the potassium, how does it happen?what is the role of calcium...

Answered by Tyree Brodnicki 2 years ago.
Elevated potassium causes the cardiac muscle cells to be unstable electrically and can cause life threatening arrythmias. The immediate goal pending removal of potassium (via dialysis) is to try to lower the level of serum potassium and stabilize the cardiac muscles cells. The role of IV calcium gluconate is to attempt to stabilize the cardiac muscle cells. It does nothing to the potassium levels in the blood. There are a couple ways to lower the life-threatening level of potassium in the blood. One way is to give dextrose (which is broken down to glucose), and it is often given with insulin. Insulin drives glucose into the cells of the body along with potassium using the sodium-potassium-ATPase enzyme. Thus the extracellular potassium becomes intracellular (pushed inside cells), and lessens the effect on cardiac muscle electrical activity. Ultimately this does not remove potassium from the body either, but lowers the amount of potassium in the blood until other means are used to eliminate it. Answered by Berenice Mccain 2 years ago.

If I start with a mixture of 50% dextrose in 50 ml, how do I dilute this to make a 10% dextrose solution?
Asked by Annamae Drexel 2 years ago.
Pour your 50 mL into a graduated cylinder and dilute to 250 mL. This will decrease the concentration by a factor of 5, just as 10% is 5 times less concentrated than 50%. Answered by Carmine Grett 2 years ago.
For most instances in chemistry, percent concentration is not used, as Molarity is a favored method of expressing the ratios of multiple elements in a solution. I will however use your format for the express purpose of answering your question. With a fifty percent concentration, you are looking at a ratio of 1:1, where for every 1 unit of concentration of dextrose, there is 1 equally sized unit of some other substance(s). A 10% concentration would have a 1:9 ratio of concentration, where for every 1 unit of your dextrose, there are nine equal portions of some other substance(s). If a 50mL mixture is at 50% concentration, You must then have a unit (25mL, unless other factors change this amount such as miscibility, fluid volume per mol, solubility, etc.) of your measured substance, and an equally sized unit of that something else (25mL). To obtain the desired concentration of 10%, you must add 8 units of the other substance. There should then be 200mL added to your mixture, and the total volume would then be 250mL.

How to determine which IV fluid patient needs? isotonic, colloid, NS, dextrose (5%, 10%, 50%)?
I know little, except DKA (DM I) or hyperosmolar (DM II) may indicate fluids. For e.g., severe hypoglycemia, give dextrose 10% or 50% until BS>100. Seen surgical clients on Ringers lactose/ NS. Any info on indication for ALL IV fluids?
Asked by Melania Osorio 2 years ago.
You're not going to give a diabetic in DKA or hyperosmolar coma dextrose. in any form. These patients need NS or in certains cases 1/2 NS. Ringer's lactate is mostly used in surgery as replacement for blood loss. Colloids are used as fluid replacement during/after surgery in cases of low oncotic pressure, people who refuse blood/blood products, or as an adjunct during massive fluid replacements (or cardiac surgery). As you stated, in cases of hypoglycemia, dextrose is appropriate. Answered by Katie Cray 2 years ago.
First a rail against a wrongheaded modern trend: I never want to be your client, which implies you're selling drugs. Eventually I may be your patient, and you could care for me. Isotonic solutions are the choice for rapid fluid expansion. That's why it's standard for surgery, so if the patient springs a leak the red stuff can be replaced with clear stuff quickly, though there are limits to how far/how well this will work, for obvious reasons. Normal saline is fine, but the difference is small enough that it really matters very little. Ringer's lactate (or for the truly picky, Ringer's pyruvate) essentially duplicates the fluids & electrolytes lost in the diarrhea of cholera. This is more for historical than aesthetic interest. For daily maintenance, isotonic solutions have considerably more salt load than is needed. If the patient is a particularly delicate one, or if you're a bit in the direction of OCD, you can calculate the component requirements individually, but for generic use, 5% dextrose will give enough sugar to keep the brain happy (the CNS gets annoyed without glucose, where other organs will more easily burn alternative calorie sources), and half or quarter normal saline, plus a bit of potassium, will supply reasonably adequate requirements, with the kidneys taking up the slack for any minor adjustments from the ideal. That pretty well covers what you'll see day-to-day. Now, TPN is a lot more complicated, but you should probably put that off for another day. Answered by Eddie Ewen 2 years ago.

Dextrose 25% 1000ml is ordered. you have 70% dextrose on hand. how much of the dextrose 70% sol. and?
how much sterile water will you use to complete this order? a. 250ml of dex. and 750 ml of water b. 357ml of dex. and 643ml of water c.424 ml of dex. and 576 ml of water d. none of the above plz show me how u solve it. thanks
Asked by Lynda Phippard 2 years ago.
You have dextrose at 70%. 50%-50% of dextrose & water will give 35% 50% dextrose *0.7 * 100 = 35% x% dextrose * 0.7 * 100 = 25 % x * 0.7 = 0.25 x=0.25 / 0.7 x=0.357 or 35.7% of 1000 ml b) 357 ml of dextrose solution at 70% topped with 643 ml of water (in the first approximation) will yield 1000 ml of solution of 25% dextrose.
