A nurse is reviewing the following ABG results for a postoperative client: pH 7.27, PaCO2 49 mm Hg, PaO2 65 mm Hg, HCO 22 mEq/L. The nurse should interpret the findings as which of the following imbalances?
Respiratory acidosis
Metabolic acidosis
Respiratory alkalosis
Metabolic alkalosis
The Correct Answer is A
The ABG results show a low pH (acidosis), a high PaCO2 (respiratory component), and a normal HCO3 (metabolic component). This indicates respiratory acidosis, which is caused by hypoventilation and retention of carbon dioxide.

Correct Answer is C
Explanation
An ileostomy is a surgical opening in the abdomen that connects the end of the small intestine (ileum) to a pouch or bag on the outside of the body. The ileostomy bypasses the large intestine (colon) and rectum, which normally absorb water and form solid stools. Therefore, the client should expect their stools to be loose and watery. The client should empty their bag several times a day, not when it is full, to prevent leakage and skin irritation. The client should avoid laxatives, which can cause dehydration and electrolyte imbalance. The client should also avoid high-fiber foods, which can cause blockage or irritation of the ileostomy.
Correct Answer is A
Explanation
A high WBC count (leukocytosis) indicates an inflammatory response to an infection, such as pneumonia. The nurse should expect to see this value in a client who has pneumonia and monitor the client for signs and symptoms of sepsis or systemic inflammatory response syndrome (SIRS). The other values are within normal or expected ranges for a client who has pneumonia.
