A nurse is caring for a client who has acute kidney injury (AKI). Which of the following arterial blood gas values would the nurse expect this client to have?

pH 7.49, HCO3 24, PaCO2 30

pH 7.26, HCO3 24, PaCO2 46

pH 7.26, HCO3 14, PaCO2 30

pH 7.49, HCO3 30, PaCO2 40

Answer and Explanation

The Correct Answer is C

Choice A Reason: This choice is incorrect because it indicates respiratory alkalosis, not AKI. Respiratory alkalosis is a condition in which the lungs eliminate too much carbon dioxide (CO2) from the blood, resulting in a low level of CO2 (PaCO2) and a high level of pH. A normal PaCO2 range is 35 to 45 mm Hg, and a normal pH range is 7.35 to 7.45, so a value of 30 mm Hg and 7.49 indicate respiratory alkalosis.

Choice B Reason: This choice is incorrect because it indicates respiratory acidosis, not AKI. Respiratory acidosis is a condition in which the lungs cannot eliminate enough CO2 from the blood, resulting in a high level of CO2 (PaCO2) and a low level of pH. A value of 46 mm Hg and 7.26 indicate respiratory acidosis.

Choice C Reason: This choice is correct because it indicates metabolic acidosis, which is a common complication of AKI. Metabolic acidosis is a condition in which the body produces too much acid or loses too much base, resulting in a low level of bicarbonate (HCO3) and a low level of pH. A normal HCO3 range is 22 to 26 mEq/L, so a value of 14 mEq/L indicates metabolic acidosis. The low PaCO2 value (30 mm Hg) is due to the respiratory compensation mechanism that tries to restore the acid-base balance by increasing the ventilation and eliminating more CO2.

Choice D Reason: This choice is incorrect because it indicates metabolic alkalosis, not AKI. Metabolic alkalosis is a condition in which the body loses too much acid or gains too much base, resulting in a high level of bicarbonate (HCO3) and a high level of pH. A value of 30 mEq/L and 7.49 indicate metabolic alkalosis.

Correct Answer is B

Explanation

Choice A Reason: This is incorrect because the laboratory values are not within the expected reference range in a client who has DIC. DIC is a condition that causes abnormal activation of the clotting cascade, leading to widespread microthrombi formation and consumption of clotting factors and platelets. This results in bleeding complications and organ dysfunction.

Choice B Reason: This is correct because the laboratory values are prolonged in a client who has DIC. PT, aPTT, and INR are tests that measure the time it takes for blood to clot. PT measures the extrinsic pathway, aPTT measures the intrinsic pathway, and INR is a standardized ratio of PT. In DIC, these tests are prolonged because of the depletion of clotting factors and platelets.

Choice C Reason: This is incorrect because the laboratory values are not the same as the previous test values in a client who has DIC. DIC is an acute and dynamic condition that can change rapidly depending on the underlying cause and treatment. The laboratory values may ﬂuctuate between normal, prolonged, or shortened depending on the balance between clotting and bleeding.

Choice D Reason: This is incorrect because the laboratory values are not decreased in a client who has DIC. Decreased laboratory values would indicate a shortened clotting time, which can occur in some cases of DIC when there is excessive clotting and thrombosis. However, this is not the typical finding in DIC, as most clients present with bleeding manifestations and prolonged clotting time.

A. Administer a nitrate antihypertensive. B. Obtain the client's heart rate. C. Assess the client for bladder distention. D. Place the client in a high-Fowler's position.

Correct Answer is D

Explanation

Choice A Reason: This is incorrect because administering a nitrate antihypertensive is not the first action, as it may cause a rapid drop in blood pressure and worsen the client's condition.

Choice B Reason: This is incorrect because obtaining the client's heart rate is not the first action, as it does not address the cause of autonomic dysreﬂexia or relieve the symptoms.

Choice C Reason: This is incorrect because assessing the client for bladder distention is not the first action, as it may take time and delay the treatment of autonomic dysreﬂexia.

Choice D Reason: This is correct because placing the client in a high-Fowler's position is the first action, as it lowers the blood pressure by promoting venous return and reducing cardiac preload.
