A client with acute renal failure is experiencing metabolic acidosis. Which intervention should the nurse anticipate to help correct the acid-base imbalance?

Administering bicarbonate intravenously to raise pH levels.

Encouraging the client to consume more acidic foods.

Increasing fluid intake to dilute acid concentrations.

Promoting shallow breathing to retain carbon dioxide.

Answer and Explanation

The Correct Answer is A

A. Correct. In acute renal failure, when the kidneys are unable to excrete acids properly, metabolic acidosis can occur. Administering bicarbonate intravenously helps raise the pH levels and correct the acid-base imbalance.

B. Incorrect. Encouraging the client to consume more acidic foods would worsen metabolic acidosis and is not a suitable intervention.

C. Incorrect. Increasing fluid intake is not a specific intervention for correcting metabolic acidosis. The focus should be on addressing the underlying acid-base imbalance.

D. Incorrect. Promoting shallow breathing to retain carbon dioxide is not a recommended intervention for correcting metabolic acidosis. Respiratory acidosis and metabolic acidosis are different types of acid-base imbalances with distinct causes and treatments.

Correct Answer is B

Explanation

A. Incorrect. Withholding food and drink for 24 hours is not necessary for a CT scan with contrast dye.

B. Correct. Before a CT scan with contrast dye, it is essential to assess the client for allergies, especially to iodine and shellfish. Contrast dyes used in CT scans contain iodine, and clients with allergies to iodine or shellfish may have an allergic reaction to the contrast dye.

C. Incorrect. While administering intravenous fluids may be beneficial in certain situations, it is not a specific precaution for a CT scan with contrast dye.

D. Incorrect. Removing jewelry and metallic objects is a standard precaution for all imaging procedures, but it is not specific to a CT scan with contrast dye.

A. To decrease urine output and prevent dehydration. B. To increase blood pressure and improve kidney perfusion. C. To promote sodium and water reabsorption in the kidneys. D. To enhance urine output and reduce fluid overload.

Correct Answer is D

Explanation

A. Incorrect. Loop diuretics are used to increase urine output, not decrease it. They help reduce fluid overload and prevent dehydration.

B. Incorrect. Loop diuretics typically lead to a decrease in blood pressure, not an increase. They are often prescribed to address hypertension in acute renal failure.

C. Incorrect. Loop diuretics promote the excretion of sodium and water from the kidneys, not their reabsorption.

D. Correct. Loop diuretics are prescribed in acute renal failure to increase urine output and promote fluid excretion. This helps reduce fluid overload and decrease edema.
