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
Explanation
Choice A reason:Increased serum amylase is a common finding in acute pancreatitis as it is released from the inflamed pancreas[^10^].
Choice B reason:A decreased WBC count is not typically associated with acute pancreatitis; an increased count may indicate infection or inflammation.
Choice C reason:Serum calcium is often decreased in acute pancreatitis due to fat saponification and hypoalbuminemia.
Choice D reason:Decreased serum lipase would not be expected; increased levels are indicative of acute pancreatitis, similar to amylase[^10^].
Correct Answer is C
Explanation
Title: Choice A reason: Liver enzymes Liver enzymes are proteins that speed up chemical reactions in your body. They include alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP). High levels of liver enzymes in the blood can indicate liver disease. However, rheumatic endocarditis is a heart condition, not a liver condition. Therefore, while liver enzymes are important for diagnosing liver conditions, they would not assist in confirming a diagnosis of rheumatic endocarditis.
Title: Choice B reason: Serum albumin Serum albumin is a type of protein that your liver and kidneys produce to help your body maintain fluid balance and function. Low or high albumin levels can indicate liver disease, kidney disease, or nutritional deficiency. However, rheumatic endocarditis is a heart condition, not a liver or kidney condition. Therefore, while serum albumin is important for diagnosing liver and kidney conditions, it would not assist in confirming a diagnosis of rheumatic endocarditis.
Title: Choice C reason: Throat culture A throat culture is a lab test used to find and identify germs in the back of your mouth that are making you sick. It can diagnose infections like strep throat, gonorrhea, thrush, diphtheria, and pertussis. Rheumatic endocarditis is often caused by a streptococcal infection, which can be identified through a throat culture. Therefore, a throat culture would assist in confirming a diagnosis of rheumatic endocarditis.
Title: Choice D reason: Arterial blood gases An arterial blood gas (ABG) test measures the levels of oxygen and carbon dioxide in your blood as well as the pH balance in your blood. It helps diagnose and monitor conditions that affect your respiratory, circulatory, and metabolic systems. However, rheumatic endocarditis is a heart condition that is often caused by a bacterial infection. Therefore, while an ABG test is important for diagnosing conditions that affect your respiratory, circulatory, and metabolic systems, it would not assist in confirming a diagnosis of rheumatic endocarditis.
