A nurse teaches a patient who is at risk for mild hypernatremia. Which statement does the nurse include in this patient's teaching?

A. Diarrhea and vomiting for 36 hours:

Diarrhea and vomiting can lead to metabolic acidosis due to loss of bicarbonate and increased hydrogen ion concentration in the blood. However, the ABG values provided indicate respiratory alkalosis (high pH and low PaCO2), which is not consistent with metabolic acidosis caused by diarrhea and vomiting. Therefore, this choice does not correlate with the ABG values.

B. Chronic obstructive pulmonary disease (COPD):

COPD is a respiratory condition characterized by airflow limitation and increased airway resistance. It can lead to respiratory acidosis due to retention of carbon dioxide (PaCO2 levels would be elevated). The ABG values in the scenario show respiratory alkalosis (low PaCO2), which is the opposite of what would be expected in COPD. Therefore, this choice does not correlate with the ABG values provided.

C. Anxiety-induced hyperventilation:

Anxiety-induced hyperventilation is a common cause of respiratory alkalosis. During hyperventilation, there is excessive elimination of carbon dioxide (PaCO2 levels decrease), leading to an increase in pH (alkalosis). The ABG values in the scenario show a high pH (7.48) and low PaCO2 (28 mm Hg), consistent with respiratory alkalosis seen in hyperventilation due to anxiety.

D. Diabetic ketoacidosis and chronic obstructive pulmonary disease (COPD):

Diabetic ketoacidosis (DKA) is a metabolic condition characterized by hyperglycemia, ketosis, and metabolic acidosis (low pH and low bicarbonate levels). COPD, as mentioned earlier, can lead to respiratory acidosis due to retained carbon dioxide. Neither of these conditions correlates with the ABG values provided, which show respiratory alkalosis (high pH and low PaCO2). Therefore, this choice does not correlate with the ABG values.

A. There is no redness, warmth, or drainage at the insertion site.

This assessment is crucial for evaluating the status of the abdominal drain site. The absence of redness, warmth, or drainage suggests that the insertion site is healing well without signs of infection or inflammation. It indicates that the drain is functioning properly and that there are no immediate complications related to the drain insertion. This assessment directly addresses the goals related to monitoring the drain site for signs of infection or dysfunction.

B. Drainage from the surgical site is 30 mL less than yesterday.

Monitoring the drainage output from the surgical site is important to assess for changes in drainage patterns. A decrease in drainage volume may indicate reduced fluid accumulation at the surgical site, potentially reflecting improved healing and decreased need for drainage. However, while this assessment is valuable, it is not as directly related to assessing the status of the drain itself or evaluating complications at the insertion site as option A.

C. The patient reports adequate pain control with medications.

Pain control is an essential aspect of postoperative care, but it is not specifically related to assessing the functionality or complications of the abdominal drain. While pain management is important for patient comfort and recovery, it does not directly address the goals related to monitoring the drain site for signs of infection, leakage, or other complications.

D. Urine is clear yellow, and urine output is greater than 40 mL/hr.

While monitoring urine output and characteristics is important for assessing renal function and hydration status, it is not directly related to assessing the abdominal drain or its complications. Clear yellow urine and adequate urine output are generally positive indicators but do not provide specific information about the functionality or status of the drain.
