A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50 (7.35 to 7.45), PaCO₂ 29 mm Hg (35 to 45 mm Hg), and HCO₃ 25 mEq/L (21 to 28 mEq/L). The nurse should identify that the client has which of the following acid-base imbalances?
Respiratory acidosis
Respiratory alkalosis
Metabolic acidosis
Metabolic alkalosis
The Correct Answer is B
Choice A Reason:
Respiratory acidosis is characterized by a low pH (below 7.35) and an elevated PaCO₂ (above 45 mm Hg). This condition occurs when there is an accumulation of carbon dioxide in the blood due to hypoventilation or impaired lung function. In this case, the client’s pH is elevated, and PaCO₂ is low, which does not align with respiratory acidosis.
Choice B Reason:
Respiratory alkalosis is indicated by a high pH (above 7.45) and a low PaCO₂ (below 35 mm Hg). This condition results from hyperventilation, which causes excessive exhalation of carbon dioxide. The client’s ABG results show a pH of 7.50 and a PaCO₂ of 29 mm Hg, consistent with respiratory alkalosis.
Choice C Reason:
Metabolic acidosis is characterized by a low pH (below 7.35) and a low HCO₃ (below 21 mEq/L). This condition occurs due to an accumulation of acids or a loss of bicarbonate in the body. The client’s pH is elevated, and HCO₃ is within the normal range, which does not indicate metabolic acidosis.
Choice D Reason:
Metabolic alkalosis is indicated by a high pH (above 7.45) and a high HCO₃ (above 28 mEq/L). This condition results from an excess of bicarbonate or a loss of acids. The client’s pH is elevated, but HCO₃ is within the normal range, which does not support a diagnosis of metabolic alkalosis.

Correct Answer is B
Explanation
Choice A Reason
4g sodium diet. While reducing sodium intake is important for managing chronic kidney disease (CKD), a specific 4g sodium diet is not typically prescribed. Instead, patients are generally advised to limit sodium intake to less than 2,300 milligrams per day to help control blood pressure and reduce fluid retention.
Choice B Reason
Potassium-restricted diet. This is the correct intervention. Patients with CKD often have difficulty excreting potassium, leading to hyperkalemia, which can be dangerous. Therefore, a potassium-restricted diet is commonly recommended to maintain normal serum potassium levels.
Choice C Reason
High-phosphorus diet. This statement is incorrect. Patients with CKD are usually advised to limit phosphorus intake because their kidneys cannot effectively excrete phosphorus, leading to hyperphosphatemia. High phosphorus levels can cause bone and cardiovascular problems.
Choice D Reason
High-protein diet. This statement is incorrect. While protein is essential, excessive protein intake can increase the workload on the kidneys. Patients with CKD are often advised to follow a moderate protein diet to reduce the production of waste products that the kidneys need to filter.
Correct Answer is C
Explanation
Choice A Reason
The client reports relief from pain when lying in the prone position. This statement is incorrect. Clients with a herniated lumbar disc typically find relief from pain when lying on their back with their knees bent or in a fetal position. Lying prone can sometimes exacerbate the pain.
Choice B Reason
The client reports that their low-back pain radiates upward toward one scapula. This statement is incorrect. Pain from a herniated lumbar disc usually radiates downward into the buttocks, legs, and sometimes the feet, not upward toward the scapula.
Choice C Reason
The client reports tingling and a burning sensation in one foot. This is the correct finding. A herniated lumbar disc can compress spinal nerves, leading to symptoms such as tingling, numbness, and a burning sensation in the legs and feet.
Choice D Reason
The client reports decreased pain when the affected leg is raised. This statement is incorrect. Raising the affected leg often increases pain due to the stretching of the sciatic nerve, which can be compressed by the herniated disc.
