NCLEX Style Study Question
An adult woman is admitted with metabolic acidosis. Which set of arterial blood gases should the nurse expect to find in a client with metabolic acidosis
- pH 7.28; PCO2 55; HCO3 26
- pH 7.50; PCO2 40; HCO3 31
- pH 7.48; PCO2 30; HCO3 22
- pH 7.30; PCO2 36; HCO3 18

Hey Tanya -
I just came across your site. It’s wonderful! I just spent the last hour going over the NCLEX questions and really appreciate the time you’ve put into this.
I’m planning on an August test date so I have to get cracking.
Thanks again,
Em.

Oh yeah: 4, right? Because metabolic means you kidneys are funky so it’s the bicard that will be low and 1 would be compensated metabolic acidosis.

Answer 4 cause: pco2 is Normal, Hco3 is dow and PH is Low like in a Metabolic Acidosis

#4 the bicarbonate level falls below normal in metabolic acidosis.

The answer to this question is number 4.

Correct answer is #4 based on the following reasons
NML ranges for AbG’s are as follows:
pH 7.35-7.45, PCO2 35-45, HCO3 22-26
1. pH 7.28; PCO2 55; HCO3 26

#4 is the answer- R O M E
pH is low - acidosis and Hco3 is low, trying to compensate and correct he problem, kidneys are hard at work

Correct answer: 4
The pH is below the normal range of 7.35-7.45. The PCO2 is within the normal range of 35-45 and the HCO3 is below the normal limits of 21-28. These values indicate a metabolic problem because the PCO2 is within normal limits. And the problem is acisosis becasue the pH is below normal.
Option 1 is respiratory acidosis becase the pH is below normal (acidosis) an dthe pCO2 is above normal, indicating the CO2 (acid) is trapped in the respiratory tract.
Option 2 is metablic alkalosis becase the pH is above normal (alkalosis), the CO2 is within normal limits, and the HCO3 (base) is above normal, indicating a base excess.
Option 3 is respiratory alkalosis becase the pH is above normal (alkalosis) and the pCO2 is below normal, indicating a deficit of CO2 in the respiratory tract.
