The nurse is caring for a diabetic patient in renal failure who is in metabolic acidosis. Which laboratory findings are consistent with metabolic acidosis?
pH 7.35, PaCO2 40 mm Hg, HCO3-25 mEq/L
pH 7.32, PaCO2 47 mm Hg. HCO3-23 mEq/L
pH 7.3, PaCO2 36 mm Hg. HCO3- 19 mEq/L
pH 7.5, PaCO2 35 mm Hg, HCO3- 35 mEq/L
The Correct Answer is C
A. pH 7.35, PaCO2 40 mm Hg, HCO3-25 mEq/L: This is within normal ranges and does not indicate acidosis.
B. pH 7.32, PaCO2 47 mm Hg. HCO3-23 mEq/L: This indicates respiratory acidosis, not metabolic.
C. pH 7.3, PaCO2 36 mm Hg. HCO3- 19 mEq/L: This indicates metabolic acidosis. The pH is low (acidic), and the HCO3- (bicarbonate) is decreased. The PaCO2 is within normal limits, indicating the respiratory system is compensating for the metabolic acidosis.
D. pH 7.5, PaCO2 35 mm Hg, HCO3- 35 mEq/L: This indicates alkalosis, not acidosis.

Correct Answer is B
Explanation
A. Deep breathing exercises should be performed regularly, regardless of the level of pain. The exercises are crucial for preventing lung complications, and pain management should be addressed so that the client can perform these exercises effectively.
B. This statement reflects a proper understanding of the importance of regular deep breathing exercises. Performing these exercises every hour while awake helps to keep the alveoli open and reduces the risk of atelectasis and pneumonia. Consistent practice is essential for maximizing lung expansion and preventing complications.
C. Coughing exercises should be performed regularly, not just when experiencing shortness of breath. Coughing helps to clear secretions from the airways and prevent their accumulation, which can lead to respiratory infections and other complications.
D. Avoiding deep breathing exercises is not advisable. While there may be some discomfort, deep breathing is essential for lung health post-operatively. The exercises help prevent complications such as atelectasis.
Correct Answer is B
Explanation
A. Abdominal pain is not a direct manifestation of respiratory acidosis. However, it may be associated with other conditions or complications but is not a primary indicator of respiratory acidosis.
B. Lethargy or drowsiness is a common symptom of respiratory acidosis. The increased CO₂ levels lead to an acidic environment that can affect brain function, resulting in decreased alertness, confusion, or drowsiness.
C. Numbness or tingling of the fingers is more commonly associated with respiratory alkalosis, which is characterized by a decreased level of CO₂ and increased blood pH. This condition can cause peripheral numbness and tingling due to altered blood pH affecting nerve function.
D. Dry skin is not a direct manifestation of respiratory acidosis. While it might be a sign of dehydration or other systemic issues, it is not specifically linked to respiratory acidosis.
