A client is admitted to the emergency room with a respiratory rate of 7/min. Arterial blood gases (ABG) reveal the following values. Which of the following is an appropriate analysis of the ABGs?
Correct Answer: B
Rationale: A low respiratory rate leads to hypoventilation, causing respiratory acidosis with a low pH and high PaCO2 due to carbon dioxide accumulation.
Question 2 of 5
A patient prescribed spironolactone is demonstrating ECG changes and complaining of muscle weakness. The nurse realizes this patient is exhibiting signs of which electrolyte imbalance?
