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 D
Explanation
Choice A: Fever and chills Fever and chills are not typically associated with the abrupt cessation of TPN. These symptoms are more commonly related to infections or inflammatory processes in the body. While infections can be a complication of TPN due to the invasive nature of the therapy, they are not a direct result of the discontinuation of the infusion. Total Parenteral Nutrition (TPN) is a method of feeding that bypasses the gastrointestinal tract. Fluids are given into a vein to provide most of the nutrients the body needs. The sudden stop in the infusion of TPN can lead to a rapid drop in blood sugar levels, known as hypoglycemia, because the body has become accustomed to the continuous influx of glucose from the TPN solution.
Choice B: Hypertension and crackles Hypertension (high blood pressure) and crackles (sounds heard on lung auscultation indicative of fluid in the air spaces) are not expected clinical manifestations due to the stopping of TPN. These symptoms are more commonly associated with cardiovascular and pulmonary conditions, respectively.
Choice C: Excessive thirst and urination Excessive thirst and urination could be symptoms of hyperglycemia (high blood sugar), which might occur if TPN is infused too quickly or if the patient has an increased insulin requirement. However, these are not the immediate concerns when TPN is abruptly stopped.
Choice D: Shakiness and diaphoresis Shakiness and diaphoresis (sweating) are common signs of hypoglycemia, which can occur if TPN is stopped suddenly. The body may have been receiving a steady supply of glucose from the TPN, and a sudden halt can cause blood sugar levels to drop quickly. This can lead to symptoms such as weakness, shakiness, sweating, and even confusion or loss of consciousness if not addressed promptly. When TPN is abruptly discontinued, the nurse should monitor the client for signs of hypoglycemia, including shakiness and diaphoresis. It is important to restart the TPN infusion as soon as possible or provide an alternative source of glucose to prevent hypoglycemia and its potential complications.
Correct Answer is B
Explanation
Choice A reason: Weight gain is not typically a direct cause of chronic pancreatitis. While obesity can be a risk factor for developing pancreatitis, it is not considered a primary cause.
Choice B reason: The use of alcohol is the most common cause of chronic pancreatitis. Long-term alcohol misuse can lead to the development of chronic pancreatitis, accounting for about 70% of cases³.
Choice C reason: Abdominal pain that is relieved with food or antacids is more indicative of conditions like peptic ulcers rather than chronic pancreatitis.
Choice D reason:Exposure to occupational chemicals has not been established as a primary cause of chronic pancreatitis. While certain toxins can affect the pancreas, they are not a common cause of chronic pancreatitis.
