Thank you for work done so far. god bless you.
I’ll like you to review this question No:20 under ABGs NCLEX Quiz 2. The correct answer you gave contradicts with the rationale -” For these ABG values, pH is NORMAL but slightly acidic and lines up with PACO2 which is METABOLIC. Therefore, this group of ABG values is considered METABOLIC ALKALOSIS.” Thank you.. pls see below.
20. Question
Match the acid-base status of the following blood samples to the disorders in the given choices. (PaCO2 values are in mm Hg and bicarbonate values in mmol/l).
pH 7.39, PaCO2 59, HCO3- 35
A. Respiratory Acidosis, Uncompensated
B. Metabolic Alkalosis, Uncompensated
C. Respiratory Acidosis, Fully Compensated
D. Metabolic Alkalosis, Partially Compensated
Correct
Correct Answer: C. Respiratory Acidosis, Fully Compensated
Based on the given ABG values, pH is 7.39. For pH, the normal range is 7.35 to 7.45. So it is NORMAL.
PaCO2 is 59. The normal range for PaCO2 is from 35 to 45. If PaCO2 is above 45, it is acidosis. Based on the given ABG values, PaCO2 is above 45, so it is considered ACIDOSIS.
HCO3- is 35. The normal range for HCO3 is from 22 to 26. If HCO3 is above 26, it is alkalosis. Based on the given ABG values, HCO3 is above 26, so it is considered ALKALOSIS.
For these ABG values, pH is NORMAL but slightly acidic and lines up with PACO2 which is METABOLIC. Therefore, this group of ABG values is considered METABOLIC ALKALOSIS.
Lastly, it is FULLY COMPENSATED because pH is normal. It is considered fully compensated if pH is normal.
Agreed, the symptoms also line up with patient being alkalosis as well: irritability and diarrhea. Assuming SaO2 levels are normal, increased respirations would point to alkalosis as well.
I beg to disagree with your analysis.
The answer is correct Respiratory Acidosis with Fully compensated. The pH is within normal limits, the PCO2 is high meaning respiratory aspect is getting acidotic and because the respiratory is getting acidotic the kidney which the HCO3 is compensating well by increasing.
A 73year man has been admitted to the unit with a diagnosis of chronic obstructive pulmonary disease .he states that he has difficulty breathing when walking short distance .he also states that his heart feels like it is racing at the same time .he states that he is tired all the time and while talking to you he is continually wringing his hands and looking out the windows.1.Identify the 4 health problem of the patient.2.formulate the nursing diagnosis
Thompson,
The PaCo2 is high and the pH is normal but slightly acidic because it is on the lower end. Using the ROME method, this would make it respiratory acidosis, fully compensated. I recommend using the ROME method (respiratory opposite metabolic equal).
In the Arterial Blood Gas Interpretation Practice Quiz (Part 1: 20 Items), I think the correct answer to Q3. should have been : Respiratory Alkalosis, Partially Compensated. Please revisit and let me know. Thanks for the resources.
This ABG’s study with the practice quiz was great and help me understand the difference in acidosis and alkalosis, respiratory versus metabolic and also compensated as well as uncompensated to fully compensated. Thanks for the resources.
The blood Ph is more towards Acidic. the PaCo2 is elevated, which is always an indicator for respiratory acidosis.
the HCO3 is also elevated, but an elevated HCO3 is is also always an indicator for Metabolic Alkalosis.
Since the Ph of the blood is is towards acidity, and the PaCO2 is elevated, the patient is in respiratory acidosis, the HCO3 is also elevated because homeostasis have set in an the body needs to form more alkaines to compensate for the increased acidity. since the Ph of the blood, though towards acidity but still within normal, that means the RESPIRATORY ACIDOSIS IS FULLY COMPENSATED.

B. Metabolic Acidosis, Partially Compensated
REASON: NORMAL
pH (ACID 0 10 ALK)
CO2 (ACID 100 0 ALK.)
HCO3 (ACID 0 50 ALK)
Thanks for this topic of ABGs here on NCLEX
I have understood this topic than I did ever in my academic career
Thanks for the lesson I can answer the question correctly

The answer is quite in order. Pls disregard comment. Thanks

The blood Ph is more towards Acidic. the PaCo2 is elevated, which is always an indicator for respiratory acidosis.
the HCO3 is also elevated, but an elevated HCO3 is is also always an indicator for Metabolic Alkalosis.
Since the Ph of the blood is is towards acidity, and the PaCO2 is elevated, the patient is in respiratory acidosis, the HCO3 is also elevated because homeostasis have set in an the body needs to form more alkaines to compensate for the increased acidity. since the Ph of the blood, though towards acidity but still within normal, that means the RESPIRATORY ACIDOSIS IS FULLY COMPENSATED.
