1. Antidiuretic Hormone (ADH):
-Regulates blood osmolarity (most important function)
-Causes kidneys to reabsorb water into the blood, < which decreases blood osmolarity
-Regulates blood pressure (minor function)
-Increases blood volume, which increases blood pressure
-Causes vasoconstriction, which increases blood pressure
2. Kidneys compensate acid base imbalance bythw following ways :-
-Fixed acid excretion
-Normal regulation of bicarbonate concentration in the blood
Kidney Regulation of Acid-Base Balance
Renal Regulation :-
-Regulation of Fixed Acids in Blood
AKA: nonvolatile acids
Produced via normal body metabolism
Cannot be converted into gases and excreted via the lungs; must go through kidneys to leave the body
Conditions that cause an abnormal increase in fixed acid production (e.g., DKA, hypoxia) leads to accelerated acid excretion to maintain homeostasis
Excretion of Fixed Acids
Since the normal amount of fixed acids is relatively small, the kidneys are able to maintain homeostasis with no problems
If the amount of organic acids is large (e.g., DKA), even healthy kidneys can't keep up over the short term
This leads to a buildup of hydrogen ion in the blood, leading to a drop in pH
#. Bicarbonate Buffer System
Step 1:
-Sodium ions are reabsorbed from the filtrate in exchange for H+ by an antiport mechanism in the apical membranes of cells lining the renal tubule
Step 2:
-The cells produce bicarbonate ions that can be shunted to peritubular capillaries
Step 3:
-When CO2 is available, the reaction is driven to the formation of carbonic acid, which dissociates to form a bicarbonate ion and a hydrogen ion
H2O + CO2 ↔ H2CO3 ↔ HCO3- + H+
Step 4:
-Bicarbonate ion passes into the peritubular capillaries and returns to the blood
-Hydrogen ion is secreted into the filtrate, where it becomes part of new water molecules and be reabsorbed as such, or removed in the urine.
3. Nurses role is very critical in infusion therapy because she is the one who calculates the dose for infusion prescribed ,does the dilution , set the flow rate etc . Any up or down will have severe effects to the patient. For example if a patient is getting TPN infusion ,and the nurse have increased the flow rate without checking glucose levels of the patient ,then the patient might go in hyperglycemia . Second example , consider a patient is getting insulin infusion , and the nurse have have increased the flow rate based on previous glucose measurements can lead to hypoglycemia .
