A client has the following arterial blood gas (ABG) results: pH 7.51, PaCO2 39 mm Hg, HCO3 32 mEq/L. How would the nurse interpret these results?
Normal values: pH: 7.35-7.45, PaCO2: 35-45 mm Hg, HCO3: 22-26 mEq/L
Uncompensated metabolic alkalosis
Uncompensated respiratory acidosis
Uncompensated metabolic acidosis
Uncompensated respiratory alkalosis
The Correct Answer is A
Choice A reason: The ABG results show an elevated pH and HCO3, which are indicative of metabolic alkalosis. The PaCO2 is within the normal range, suggesting that it is uncompensated.
Choice B reason: Respiratory acidosis would be indicated by an elevated PaCO2 and a decreased pH, which is not the case here.
Choice C reason: Metabolic acidosis would be indicated by a decreased pH and HCO3, which is not consistent with the given results.
Choice D reason: Respiratory alkalosis would be indicated by a decreased PaCO2 and an increased pH, which is not consistent with the given results.

Correct Answer is B
Explanation
Choice A reason: A high-fat diet is not recommended for clients with chronic pancreatitis as it can exacerbate symptoms and lead to malabsorption issues.
Choice B reason: Checking blood glucose is important because chronic pancreatitis can affect the endocrine function of the pancreas, potentially leading to diabetes.
Choice C reason: While a semi-Fowler's position may be comfortable for some patients, it is not specifically an intervention for chronic pancreatitis.
Choice D reason: Assessing for hypotension is a general nursing intervention but not specific to the management of chronic pancreatitis.
Correct Answer is C
Explanation
Choice A reason: The ABG values provided are within normal limits and do not indicate a complication of sepsis.
Choice B reason: A temperature of 100.8°F suggests an infection but is not specific enough to indicate a complication of sepsis.
Choice C reason: A platelet count of 99,000/mm3 is below the normal range and can indicate a complication of sepsis known as disseminated intravascular coagulation (DIC), which is a serious condition that can lead to severe bleeding or blood clots.
Choice D reason: A urine culture positive for gram-negative bacteria indicates an infection, which could be the source of sepsis, but it does not specifically indicate a complication of sepsis.
