NCLEX: MARK KLIMEK - LECTURE 1
(ACID/BASE BALANCE) EXAM
QUESTIONS WITH CORRECT ANSWERS
What are the normal pH values? - Answer- 7.35-7.45
What are the normal CO2 values? - Answer- 35-45
What are the normal HCO3 values? - Answer- 22-26
If pH is <7.35, the acid-base imbalance is... - Answer- Acidic
If pH is >7.35, the acid-base imbalance is... - Answer- Alkalotic
If the pH and Bicarb move in the SAME direction, then the acid-base imbalance is... -
Answer- Metabolic
If the pH and Bicarb move in the OPPOSITE direction, then the acid-base imbalance
is... - Answer- Respiratory
(Example #1) Metabolic or respiratory? pH=7.3, HCO3=20 - Answer- Metabolic
acidosis
(Example #2) Metabolic or respiratory? pH=7.58, HCO3=32 - Answer- Metabolic
alkalosis
(Example #3) Metabolic or respiratory? pH=7.22, HCO3=35 - Answer- Respiratory
acidosis
"As the pH goes... - Answer- ... so goes my patient, except for potassium."
If pH goes over 7.45, s/s include... - Answer- pH is up, so my patient goes up... except
for potassium.
Tachycardia, tachypnea, HTN, seizures, irritability, spastic, diarrhea, borborygmic
(increased bowel sounds), hyperreflexia (3+, 4+)..... HYPOkalemia!
What is the nursing intervention for s/s of ALKALOSIS? - Answer- Patient needs
suctioning because of seizures.
If pH goes below 7.35, s/s include... - Answer- pH is down, so my patient goes down...
except for potassium.
