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. Arrange for the patient to receive gamma globulin.

Gamma globulin is a blood product that contains antibodies and is sometimes used for post-exposure prophylaxis in certain situations, such as for individuals who are immunocompromised or pregnant and have been exposed to varicella (chickenpox) or measles. However, for a frail, older adult who had chickenpox as a child and has been exposed to varicella again, arranging for gamma globulin may not be necessary if the patient is already immune to chickenpox.

B. Assess frequently for herpes zoster.

Herpes zoster (shingles) is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. While exposure to varicella can increase the risk of developing shingles in individuals who are susceptible, frequent assessment for herpes zoster is not necessary in this case if the patient is known to have had chickenpox in the past.

C. Be aware of the patient's immunity to chickenpox.

This option is the correct choice. Since the patient had chickenpox as a child, they likely have immunity to chickenpox. Being aware of this immunity helps the nurse understand that the patient may not develop chickenpox again even after exposure to varicella.

D. Encourage the patient to have a pneumonia vaccine.

Encouraging the patient to have a pneumonia vaccine is unrelated to the immediate concern of exposure to varicella. While pneumonia vaccines are important for older adults, especially those who are frail, the priority in this scenario is to determine the patient's immunity to chickenpox due to prior infection.

A. Metabolic acidosis:

Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (<22 mEq/L) due to an excess of acids in the body or a loss of bicarbonate. However, in the given ABG values, the pH is low (7.22), but the bicarbonate level is elevated (28 mEq/L), which does not align with metabolic acidosis. Therefore, metabolic acidosis is not the correct interpretation in this case.

B. Respiratory acidosis:

Respiratory acidosis occurs when there is inadequate removal of carbon dioxide (CO2) by the lungs, leading to an accumulation of CO2 in the blood and a decrease in pH. In the ABG values provided, the pH is low (7.22), and the PaCO2 is elevated (68 mm Hg), indicating respiratory acidosis as the primary disturbance. This interpretation is supported by the elevated PaCO2 and the low pH, making it the correct choice based on the given data.

C. Respiratory alkalosis:

Respiratory alkalosis results from hyperventilation, leading to excessive elimination of CO2 and a decrease in PaCO2 levels. However, in the ABG values presented, the PaCO2 is elevated (68 mm Hg), which contradicts the expected decrease seen in respiratory alkalosis. Therefore, respiratory alkalosis is not the correct interpretation of the ABG values in this case.

D. Metabolic alkalosis:

Metabolic alkalosis is characterized by a high pH (>7.45) and a high bicarbonate level (>26 mEq/L) due to excessive loss of acids or an increase in bicarbonate levels. However, in the ABG values provided, the pH is low (7.22), and the bicarbonate level is elevated (28 mEq/L), which is not consistent with metabolic alkalosis. Therefore, metabolic alkalosis is not the correct interpretation based on the given data.
