Metabolic by Electrolytes
Posted by Laura on December 10, 2009
You can tell if a person has Metabolic Acidosis by using the Anion Gap.
The Anion Gap is a difference between the cations and anions. The anion gap indicator # you look at is > 20 mEq for Metabolic Acidosis. Cations are the positive ions in the serum. Anions will are the negatives. Na and K (sodium, potassium) are positive (cations). Cl and HCO3 (chloride and bicarbonate) are negatives (anions).
So here’s the math:
Now the Question is –
Is metabolic acidosis present (anion gap > 20 mEq/L) ?
Answer – Yes, metabolic acidosis is present with an anion gap of 24.

Affecting Fluids and Electrolytes
Posted by Laura on December 8, 2009
Fluid and Electrolytes
Hormones regulating water retention and loss
ADH (anti-diuretic hormone) * regulates WATER excretion from the kidneys. As serum osmolality rises (>300), it stimulates osmoreceptors that stimulate thirst to ↑ H2O intake & stimulate ADH release to allow more water reabsorption in the kidney causing dilution of body fluids.
- water only, urine will be dark, scant, amber-colored,
- alcohol consumption turns ADH off and you are dehydrated the next day
- ADH & Aldosterone activate in ↓ BP
ADH keeps water from being loss through urination.
Aldosterone * Renin-Angiotensin System * regulates electrolyte balance from the kidneys by promoting Na+ & water retention and K+ loss
- with low blood volume such as internal bleeding or cut arm, kidneys kick in to reabsorb water
- this system works with salt to counteract effects of low blood volume & low BP to try to increase BP (water & salt reabsorbed)
Aldosterone, Renin-Angiotensin System keeps water and sodium from being loss through urination, though Potasium is loss.
ANP (atrial natriuretic peptide) * cardiac hormone found in atria & released when atria are stretched by increasing blood volume or BP (CHF) works to lower BP/volume through vasodilation & suppression of RAS (rennin-angiotensin system)
ANP is a marker found through testing, signifying CHF. ANP tries to lower BP/Volume that ADH and ARAS creates.

Respiratory or Metabolic Acidosis or Alkalosis?
Posted by Laura on December 8, 2009
This is the way I see it.
pH norm = 7.4 +/- 0.05
PaCO2 norm = 40 +/- 5
HCO3 norm = 24 +/- 2
- If your pH is low and your PaCO2 is high (inverse) you have RESPIRATORYacidosis.
- If your pH is high and your PaCO2 is low (inverse) you have RESPIRATORY alkalosis
- If your pH is low and your HCO3 is low, (and your PaCO2 is normal or low) you have Metabolic acidosis
- If your pH is high and your HCO3 is high, (and your PaCO2 is normal or high) you have Metabolic alkalosis

Daily 5 – Say What?
Posted by Laura on December 6, 2009
Starting Monday I will do a Daily 5, well… maybe starting today. My study schedule is pretty much in the order of the modules we have 1-14 (minus the last 4 tested on), so the questions will come from these areas. If you find this helpful, you must add questions of your own. Please put them in the comments so everyone can try them!

PPN mixture:
10% dextrose 500 mL added to 8.25% Aminosyn 500 mL running at 45 mL per hour
TPN mixture:
50% dextrose 500 mL added to 8.25% Aminosyn 500 mL running at 85 mL per hour, plus 500 mL of Lipsyn 20% to be run over 20 hours each day
not sure on this last one – verifying with Harmon 🙂
Harmon says correct. Hmmmm.

What is MAO, and how come it keeps coming up in my reading of drugs?
Posted by Laura on November 9, 2009
Since there is great risk for patients on MAO inhibitors, I know I need to understand this area better. Here is what I found out:
MAO stands for monoamine oxidase. Monoamine oxidases are enzymes that catalyze the oxidation of monoamines. In other words, these enzymes oxidize or use oxygen to remove an amine group from a molecule.
Starting off we have a monamine molecule. The one above is a base (R) with 2 hydrogen and one ammonia component, plus water and oxygen. We then used MAO (the oxidase) to pull the amino group from the molecule resulting in the amino, 1 hydrogen and 1 oxygen plus the ammonia and water molecules.
Okay, so we know what MAO is. Now a MAO inhibitor would keep this from happening, right? To know why we want it to be inhibited, we need to understand why it normally happens. From what I have read, the normal MAO which happens in our body functions to monitor how many neurotransmitters get to function. If MAOs are increased, then they will be lowering the neurotransmitters activity such as serotonin, norepinephrine, epinephrine and dopamine. Depending if MAO is overworking, or under-working a patient could have depression, schizophrenia, substance abuse, ADD, and migraines.
So now I understand why having our MAOs working correctly is important. If a person is on MAO therapy, then any other drug that may also depress these neurotransmitters – or increase them, will obviously counter act with the MAO drugs and create problems.
Not only other drugs but food also. This example is given in the Tabers (p. 1485) An MAO inhibitor (MAOI) is used to treat depression and Parkinson’s disease. A tyramine-containing food such as cheese can upset this balance.
If you have a MAO excess, then you will have an increased breakdown of catecholamines in your bloodstream. Catecholamines are serotonin, dopamine, metanephrine, norepinephrine, and epinephrine. They are derived from the amino acid tyrosine.
In the Taber’s example, taking an MAO inhibitor will help to not form the tyrosine base by itself. But if you eat certain cheeses (and are using certain MAOI) you just re-establish the high load of tyrosine in your body canceling out the effect of the MAOI.
