Mark Klimek NCLEX Review EXAM ALL 300
RANDOMIZED PRACTICE QUESTIONS WITH
ANSWERS & RATIONALES LATEST VERSION THIS
YEAR
1. What are the normal pH values?


A) 7.25–7.35


B) 7.35–7.45


C) 7.45–7.55


D) 7.30–7.40


Answer: B


Normal pH values are 7.35–7.45. Values below 7.35 indicate acidosis; values above 7.45 indicate alkalosis.




2. What are the normal CO₂ values?

, Page 2 of 192




A) 22–26


B) 30–40


C) 35–45


D) 45–55


Answer: C


Normal CO₂ (PaCO₂) values are 35–45. CO₂ is the respiratory component of acid-base balance.




3. What are the normal HCO₃ values?


A) 15–20


B) 20–25


C) 22–26


D) 25–30


Answer: C


Normal bicarbonate (HCO₃) values are 22–26. HCO₃ is the metabolic component of acid-base balance.

4. If pH is < 7.35, the acid-base imbalance is classified as:


A) Alkalotic


B) Acidic


C) Normal


D) Compensated


Answer: B


If pH is < 7.35, the imbalance is acidic (acidosis). If pH is > 7.45, it is alkalotic (alkalosis).




5. If the pH and Bicarb move in the SAME direction, the acid-base imbalance is:


A) Respiratory


B) Metabolic


C) Mixed


D) Compensated

, Page 4 of 192




Answer: B


If pH and HCO₃ move in the same direction, the imbalance is metabolic. If they move in opposite


directions, it is respiratory.




6. If the pH and Bicarb move in the OPPOSITE direction, the acid-base imbalance is:


A) Metabolic


B) Respiratory


C) Mixed


D) Compensated


Answer: B


If pH and HCO₃ move in opposite directions, the imbalance is respiratory.




7. pH = 7.3, HCO₃ = 20. What is the acid-base imbalance?
