A nurse is assessing a client with chronic renal failure for fluid overload. Which finding should the nurse prioritize as an early indication of fluid retention?
Increased blood pressure readings.
Shortness of breath and crackles in the lungs.
Decreased serum potassium levels.
Rapid weight loss over a few days.
The Correct Answer is A
A. Correct. An increase in blood pressure readings can be an early indication of fluid retention in a client with chronic renal failure. Fluid overload can lead to hypertension as the kidneys struggle to excrete excess fluids.
B. Incorrect. Shortness of breath and crackles in the lungs are signs of fluid overload but are considered more advanced symptoms. These indicate that fluid has accumulated in the lungs, leading to pulmonary edema.
C. Incorrect. Decreased serum potassium levels (hypokalemiA. are not typically associated with fluid overload. Instead, chronic renal failure often leads to hyperkalemia due to impaired potassium excretion.
D. Incorrect. Rapid weight loss over a few days is not indicative of fluid retention; rather, it may suggest dehydration or inadequate caloric intake.

Correct Answer is B
Explanation
A. Incorrect. Phosphate binders are not used to reduce calcium absorption. They are specifically prescribed to control phosphate levels in the blood.
B. Correct. Phosphate binders are medications that bind to dietary phosphorus in the digestive tract, preventing its absorption and reducing phosphate levels in the blood. This helps manage hyperphosphatemia, a common complication in chronic renal failure.
C. Incorrect. Phosphate binders do not improve iron absorption or manage anemia. They are not related to iron metabolism.
D. Incorrect. Phosphate binders do not affect potassium excretion. They are specific to phosphate control in the body and do not impact potassium levels.
Correct Answer is A
Explanation
A. Correct. ACE inhibitors are commonly prescribed to manage hypertension and fluid overload in clients with chronic renal failure. These medications help relax blood vessels, reduce fluid retention, and lower blood pressure.
B. Incorrect. Phosphate binders are prescribed to control phosphate levels, but they do not directly address fluid overload and hypertension.
C. Incorrect. Erythropoietin-stimulating agents (ESA. are used to manage anemia in chronic renal failure and do not specifically address hypertension or fluid overload.
D. Incorrect. Potassium-sparing diuretics may not be the first for managing fluid overload and hypertension in chronic renal failure, especially if the client has elevated potassium levels. ACE inhibitors are a more suitable option in this scenario.
