A nurse is reviewing the arterial blood gas (ABG) values of a client who has chronic kidney disease. Which of the following sets of values should the nurse expect?
pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg
pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg
The Correct Answer is A
Choice A reason:
This set of values indicates metabolic acidosis, which is common in chronic kidney disease due to the accumulation of acids in the body as the kidneys fail to eliminate them effectively³.
Choice B reason:
A pH of 7.50 is considered alkalotic, and while HCO3- and PaCO2 are within normal ranges, this set of values does not typically represent chronic kidney disease.
Choice C reason:
A pH of 7.55 is also alkalotic, and an HCO3- of 30 mEq/L indicates metabolic alkalosis, which is not characteristic of chronic kidney disease.
Choice D reason:
While a pH of 7.30 is on the lower end of the normal range, an HCO3- of 26 mEq/L is within the normal range, and a PaCO2 of 50 mm Hg indicates respiratory acidosis, not typically seen in chronic kidney disease without concurrent respiratory issues.

Correct Answer is ["A","B","C","D","E","F"]
Explanation
Choice A reason:Profuse vomiting with a fecal odor can occur in large bowel obstructions due to the backward flow of bowel contents.
Choice B reason:Epigastric abdominal distention is a common finding in bowel obstructions due to the accumulation of gas and fluids.
Choice C reason:Intermittent abdominal cramping results from the bowel's attempt to push contents through the obstructed area.
Choice D reason:Ribbon-like stools or diarrhea may occur if there is a partial obstruction allowing some contents to pass.
Choice E reason:Metabolic acidosis can develop due to the accumulation of lactic acid from tissue hypoxia and decreased perfusion.
Choice F reason:Severe fluid and electrolyte imbalance can result from vomiting and the inability to absorb fluids and nutrients properly.
Correct Answer is C
Explanation
Choice A reason:Shaking the bag is not recommended as it may not adequately mix the solution and could cause emulsion instability.
Choice B reason:Administering the bag as is could be harmful due to the risk of fat embolism or other complications from an unstable emulsion.
Choice C reason:Returning the bag to the pharmacy is the appropriate action to ensure the client receives a properly mixed and safe emulsion.
Choice D reason:Turning the bag upside down one time is not sufficient to mix the emulsion and does not address the potential instability of the solution.
