A client is admited 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?

Choice A: Metabolic acidosis is incorrect because it is characterized by a low pH and a low HCO3, not a high PaCO2. Metabolic acidosis occurs when there is an excess of metabolic acids in the body, such as lactic acid, ketoacids, or salicylates.

Choice B: Respiratory alkalosis is incorrect because it is characterized by a high pH and a low PaCO2, not a low pH and a high PaCO2. Respiratory alkalosis occurs when there is excessive loss of carbon dioxide through hyperventilation, such as in anxiety, fever, or aspirin overdose.

Choice C: Respiratory acidosis is correct because it is characterized by a low pH and a high PaCO2. Respiratory acidosis occurs when there is impaired gas exchange or hypoventilation, resulting in accumulation of carbon dioxide in the blood. This can be caused by conditions such as chronic obstructive pulmonary disease (COPD), pneumonia, asthma, or chest trauma.

Choice D: Metabolic alkalosis is incorrect because it is characterized by a high pH and a high HCO3, not a low pH and a high PaCO2. Metabolic alkalosis occurs when there is a loss of metabolic acids or an excess of bicarbonate in the body, such as from vomiting, gastric suctioning, or diuretic therapy.

Choice A Reason: This is correct because phosphorus is a mineral that is essential for bone health, energy metabolism, and acid-base balance. Hypophosphatemia is a low level of phosphorus in the blood, which can cause muscle weakness, bone pain, and confusion. The nurse should request a dietitian consult for selecting foods high in phosphorus, such as dairy products, meat, fish, eggs, nuts, and beans.

Choice B Reason: This is incorrect because poultry, peanuts, and seeds are foods that are high in phosphorus, not low. The nurse should not instruct the patient to avoid these foods, as they can help increase the serum phosphorus level and prevent further complications of hypophosphatemia.

Choice C Reason: This is incorrect because aluminum hydroxide antacids are medications that can lower the serum phosphorus level by binding to phosphorus in the gastrointestinal tract and preventing its absorption. The nurse should not provide aluminum hydroxide antacids as prescribed, as they can worsen the patient's condition and cause aluminum toxicity. The nurse should consult with the provider about alternative medications for treating stomach ulcers that do not affect phosphorus levels.

Choice D Reason: This is incorrect because sodium phosphate is a medication that can raise the serum phosphorus level by providing supplemental phosphorus. The nurse should not instruct the patient to avoid the intake of sodium phosphate, as it can help correct hypophosphatemia and restore normal phosphorus balance. The nurse should administer sodium phosphate as ordered and monitor the patient's serum phosphorus level and renal function.
