A nurse is reviewing the client's medical record in the presurgical holding area. Which of the following places the client at risk for a surgical site infection?

A. Diabetic ketoacidosis (DKA) in a person with emphysema:

In DKA, there is typically metabolic acidosis due to the accumulation of ketones in the blood, leading to a decrease in pH. However, the respiratory compensation mechanism in DKA usually results in a decreased PaCO2 (respiratory alkalosis) rather than an elevated PaCO2 as seen in the blood gas values provided. Additionally, emphysema is associated with chronic respiratory acidosis, not respiratory alkalosis as indicated by the elevated PaCO2.

B. Diarrhea for 36 hours in an older, frail woman:

Prolonged diarrhea can lead to metabolic acidosis due to the loss of bicarbonate through the gastrointestinal tract. The pH of 7.12 and the decreased HCO3- (22 mEq/L) suggest metabolic acidosis. However, the elevated PaCO2 (respiratory acidosis) is not consistent with pure metabolic acidosis caused by diarrhea. Respiratory acidosis typically occurs due to hypoventilation or respiratory dysfunction.

C. Anxiety-induced hyperventilation in an adolescent:

Anxiety-induced hyperventilation can lead to respiratory alkalosis due to excessive blowing off of CO2, resulting in a decrease in PaCO2. The pH of 7.12 is consistent with acidosis, but the elevated PaCO2 contradicts respiratory alkalosis. Anxiety-induced hyperventilation would typically result in a higher pH and lower PaCO2.

D. Bronchial obstruction related to aspiration of a hot dog:

A bronchial obstruction causing inadequate ventilation can lead to respiratory acidosis due to CO2 retention. The pH of 7.12 and the elevated PaCO2 (65 mm Hg) indicate respiratory acidosis. This situation is consistent with the blood gas values provided.

A. "Bake or grill the meat rather than frying it."

This statement is more related to reducing fat intake rather than managing sodium levels. While reducing fried foods can be beneficial for overall health, it doesn't directly address the issue of sodium intake, which is crucial in managing hypernatremia.

B. “Check your radial pulse twice a day.”

Checking the radial pulse is a method used to monitor heart rate and rhythm. It is not directly related to managing sodium levels or hypernatremia. Although monitoring vital signs is important in general health care, it is not specific to addressing mild hypernatremia.

C. "Read food labels to determine sodium content."

This statement is the correct choice. Managing sodium intake is a key component in managing hypernatremia. Reading food labels helps patients identify high-sodium foods and make choices that are lower in sodium content, which can be crucial in preventing or managing mild hypernatremia.

D. “Weigh yourself every morning and every night."

While regular weight monitoring can be important for certain health conditions, it is not directly related to managing mild hypernatremia. Weight changes may occur with fluid retention or loss, but monitoring sodium intake and hydration status is more directly relevant to managing hypernatremia.
