The nurse is caring for a patient who is lethargic and dehydrated. Arterial blood gas (ABG) results show pH 7.50, PaO2 85 mmHg, PaCO2 45 mmHg, HCO3 35 mEq/L. What acid-base imbalance will the nurse recognize the patient is at risk for?

Respiratory alkalosis, uncompensated

Respiratory acidosis, partially compensated

Metabolic acidosis, uncompensated

Metabolic alkalosis, partially compensated

Answer and Explanation

The Correct Answer is D

Choice A reason: Respiratory alkalosis with uncompensated imbalance would show a low PaCO2, not a normal value.

Choice B reason: Respiratory acidosis with partially compensated imbalance would show a low pH and high PaCO2 with an elevated bicarbonate level.

Choice C reason: Metabolic acidosis with uncompensated imbalance would show a low pH and low bicarbonate level.

Choice D reason: Metabolic alkalosis with partially compensated imbalance is indicated by the elevated pH and bicarbonate level, while

Correct Answer is C

Explanation

Choice A reason: Avoiding foods that are high in sodium such as canned soups and processed meats is correct. High sodium intake can worsen fluid retention and hypertension, which are concerns in chronic kidney disease.

Choice B reason: Limiting intake of high-potassium foods like bananas and tomatoes is correct. High potassium levels can lead to dangerous cardiac arrhythmias in patients with chronic kidney disease.

Choice C reason: Eating a high-protein diet with lots of dark green, leafy vegetables is incorrect. While protein is important, excessive protein intake can increase the workload on the kidneys. Patients with chronic kidney disease often need to limit protein intake to prevent further kidney damage. Additionally, dark green, leafy vegetables are high in potassium, which should be limited.

Choice D reason: Monitoring fluid intake to prevent fluid overload is correct. Fluid overload can lead to hypertension, edema, and heart failure in patients with chronic kidney disease.

A. Administer platelet transfusion immediately. B. Monitor the patient for signs of bleeding and educate about bleeding precautions. C. Administer aspirin to reduce the risk of clot formation. D. Encourage the patient to engage in regular physical exercise to improve circulation.

Correct Answer is B

Explanation

Choice A reason: Administering a platelet transfusion immediately is not indicated for a platelet count of 45,000/mm³. While this is below the normal range, it is not critically low. Platelet transfusions are typically reserved for patients with life-threatening bleeding or extremely low platelet counts.

Choice B reason: Monitoring the patient for signs of bleeding and educating about bleeding precautions is the appropriate intervention. Patients with thrombocytopenia are at an increased risk of bleeding, and it is essential to educate them on how to minimize this risk, such as avoiding activities that can cause injury, using a soft toothbrush, and avoiding over-the-counter medications that can affect platelet function.

Choice C reason: Administering aspirin to reduce the risk of clot formation is incorrect. Aspirin is an antiplatelet agent that can increase the risk of bleeding in patients with thrombocytopenia. It should be avoided unless specifically prescribed for another condition with close monitoring.

Choice D reason: Encouraging the patient to engage in regular physical exercise to improve circulation is not appropriate in this context. While physical activity is generally beneficial, it should be done with caution in patients with thrombocytopenia to avoid injury and bleeding. The focus should be on safety and bleeding precautions.
