A nurse is caring for a client who has acute kidney injury. The client's ABGS are:

PH:7.26

PaCO2: 30 mm Hg

HCO3: 14 mEq/L

Which of the following acid-imbalances should the nurse identify the client is experiencing?

A. Small for gestational age:

While being small for gestational age can contribute to respiratory difficulties in newborns, it is not directly associated with respiratory distress syndrome or respiratory acidosis. Other factors, such as prematurity or intrauterine growth restriction, may play a more significant role.

B. Cesarean birth:

Cesarean birth can predispose newborns to respiratory difficulties, including respiratory distress syndrome. During vaginal birth, the compression of the chest during passage through the birth canal helps expel lung fluid, whereas babies born via cesarean section may have more retained lung fluid, leading to respiratory distress.

C. Ventricular septal defect:

Ventricular septal defect is a congenital heart defect and is not directly associated with respiratory distress syndrome or respiratory acidosis. However, congenital heart defects can affect the cardiovascular system, leading to respiratory compromise in some cases.

D. Maternal history of asthma:

While maternal asthma can increase the risk of respiratory problems in newborns, it is not directly related to respiratory distress syndrome or respiratory acidosis. Maternal asthma may increase the likelihood of the newborn developing asthma or other respiratory conditions later in life.

(A) Respiratory acidosis: Respiratory acidosis is characterized by a low pH (<7.35) and a high PaCO2 (>45 mm Hg). In this case, the client’s pH is high and PaCO2 is normal, which rules out respiratory acidosis.

(B) Respiratory alkalosis: Respiratory alkalosis is characterized by a high pH (>7.45) and a low PaCO2 (<35 mm Hg). Although the client’s pH is high, the PaCO2 is normal, which rules out respiratory alkalosis.

(C) Metabolic acidosis: Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (<22 mEq/L). The client’s pH and bicarbonate levels are both high, which rules out metabolic acidosis.

(D) Metabolic alkalosis: Metabolic alkalosis is characterized by a high pH (>7.45) and a high bicarbonate level (>26 mEq/L). The client’s pH is 7.6 and bicarbonate level is 32 mEq/L, both of which are higher than normal. This indicates metabolic alkalosis. Therefore, the nurse should identify that the client is experiencing metabolic alkalosis.
