The nurse is caring for a patient with end-stage kidney disease (ESKD). Which arterial blood gas results (ABG) will the nurse correlate with the patient's condition?
pH 7.21, PaCO2 36, HCO3 14
pH 7.50, PaCO2 29, HCO3 22
pH 7.47, PaCO2 45, HCO3 33
pH 7.31, PaCO2 48, HCO3 24
The Correct Answer is A
Choice A reason: The ABG results of pH 7.21, PaCO2 36, HCO3 14 indicate metabolic acidosis, which is common in patients with end-stage kidney disease (ESKD). In ESKD, the kidneys lose their ability to excrete acid and maintain bicarbonate levels, leading to an accumulation of acid in the blood. This condition results in a low pH (acidic), normal PaCO2 (as the respiratory system attempts to compensate), and low HCO3 (bicarbonate).
Choice B reason: The ABG results of pH 7.50, PaCO2 29, HCO3 22 indicate respiratory alkalosis, which is not typically associated with ESKD. Respiratory alkalosis occurs when there is excessive exhalation of carbon dioxide, leading to a higher pH (alkaline). This condition is more likely to be seen in situations such as hyperventilation, anxiety, or certain lung diseases.
Choice C reason: The ABG results of pH 7.47, PaCO2 45, HCO3 33 indicate metabolic alkalosis, which is not typically associated with ESKD. Metabolic alkalosis occurs when there is an excess of bicarbonate or a loss of acid. This condition can result from factors such as vomiting, diuretic use, or excessive antacid consumption. It is not a common finding in patients with ESKD.
Choice D reason: The ABG results of pH 7.31, PaCO2 48, HCO3 24 indicate respiratory acidosis, which is not typically associated with ESKD. Respiratory acidosis occurs when there is an accumulation of carbon dioxide due to impaired respiratory function. This condition is more likely to be seen in chronic obstructive pulmonary disease (COPD) or other respiratory disorders. It is not a common finding in patients with ESKD.

Correct Answer is C
Explanation
Choice A reason: Platelet transfusions are typically reserved for patients with severe bleeding or extremely low platelet counts. They are not a standard treatment for managing ITP unless there is significant bleeding.
Choice B reason: Plasma albumin is not a treatment for ITP. It is used for other conditions such as hypovolemia and hypoalbuminemia but does not address the underlying immune-mediated destruction of platelets in ITP.
Choice C reason: Intravenous immunoglobulin (IVIG) is a treatment for ITP that helps increase platelet counts by modulating the immune system. It is often used in acute settings to manage severe thrombocytopenia and bleeding.
Choice D reason: Factor D is not related to the treatment of ITP. It is involved in the complement system, which is part of the immune response but does not directly address the platelet destruction seen in ITP.
