A nurse working in the perioperative area is reviewing the Quality and Safety Education in Nursing (QSEN) competencies. Which of the foIIowing competencies should the nurse identify as the priority when caring for a client during the perioperative period?

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. “Call your surgeon if you have any questions at home.”

This instruction is important as it encourages the patient to seek help and clarification if they have any concerns or questions about their postoperative care at home. However, while communication with the surgeon is essential, it is not as immediately critical as ensuring proper hand hygiene when dealing with wound care and drain management.

B. ”Eat a diet high in protein, iron, zinc, and vitamin C.”

Nutritional advice is crucial for postoperative recovery, as a balanced diet high in protein, iron, zinc, and vitamin C can promote wound healing and overall recovery. However, while important for long-term recovery and healing, dietary recommendations do not directly address the immediate risk of infection or complications associated with wound care and drain management.

C. “Wash your hands before touching the drain or dressing."

This instruction is the most important in this context because proper hand hygiene is crucial for preventing infections during wound care and drain management. Clean hands significantly reduce the risk of introducing harmful bacteria or contaminants to the surgical site, which can lead to infections and other complications. Ensuring that the patient washes their hands before touching the drain or dressing is a fundamental measure for promoting wound healing and preventing postoperative complications.

D. “Be sure you keep all your postoperative appointments.”

Keeping postoperative appointments is important for ongoing assessment, monitoring, and follow-up care. However, while essential for overall recovery and management of postoperative issues, it is not as immediate or directly related to the patient's ability to manage their dressing and drain at home.
