Acid Base Imbalances
Which of the following are part of the renal system regulation? SATA*
secretion of free hydrogen ions
combining H+ with ammonia (NH3)
conserving bicarbonate
Feedback
The kidneys reabsorb bicarbonate and hydrogen ions from the urine back into the bloodstream or can excrete them in the
urine in response to the blood levels of hydrogen. Kidneys can also produce more bicarbonate as needed.
Which of the following ABG would you expect to see on a healthy individual? *
pH: 7.45 CO2: 35 HCO3: 26 PaO2: 50
pH: 7.48 CO2: 35 HCO3: 28 PaO2: 88
pH: 7.32 CO2: 55 HCO3: 26 PaO2: 58
pH: 7.38 CO2: 40 HCO3: 26 PaO2: 80
Feedback
You need to know normal values - be sure to look them up; maybe put them on your note sheet for the exams.
Which of the following are compensatory responses to a pH of 7.50? SATA*
decreased respiratory rate and depth
movement of H into cells and pulling K out
increased excretion of HCO3
muscle spasms
Feedback
In alkalotic states the kidneys try to get rid of bicarb and the lungs try to hold on to CO2 by decreasing rate and depth, but the
brain will not let us stop breathing so compensation will be limited.
Which of the following are interventions/treatment for a a pH of 7.50? SATA*
decrease rate/volume
give acetazolamide
give benzos
fix underlying issue
Feedback
We also start with trying to fix the cause of any imbalance. If metabolic alkalosis we could try acetazolamide to encourage
the kidneys to excrete bicarb. It is is a respiratory alkalosis, we could decrease rate/volume if on mechanical ventilation or
give a benzo if it is due to anxiety.
Which of the following are compensatory responses to a pH of 7.30? SATA*
Increased rate and depth of respirations
Increase H excretion
Moving K into and H out of the cells
HCO3 retention
Feedback
In an acidosis, the lungs will respond with increasing rate and depth of respiration - Kussmaul respirations. The kidneys will
hold on to bicarb and excrete hydrogen ions. Hydrogen will also move into the cells resulting in K moving into the blood
stream resulting in hyperkalemia.
What is the mnemonic to assist with identifying the cause of an acid/base imbalance?*
