Correct Answer is D

Explanation

A. Incorrect. Hyperkalemia, or high potassium levels, can cause muscle weakness and potentially cardiac arrhythmias, but it is not typically associated with difficulty concentrating or irritability.

B. Incorrect. Hyponatremia, or low sodium levels, can cause neurological symptoms such as confusion and headache, but it is not typically associated with muscle cramps.

C. Incorrect. Hypocalcemia, or low calcium levels, can cause muscle cramps and neurological symptoms, but it is not specifically associated with difficulty concentrating and irritability.

D. Correct. Hyperphosphatemia, or high phosphorus levels, is common in chronic renal failure due to impaired kidney function. Elevated phosphorus levels can lead to the binding of calcium, resulting in decreased ionized calcium in the blood. This can cause neuromuscular irritability, difficulty concentrating, and muscle cramps.

A. Increased blood pressure readings. B. Shortness of breath and crackles in the lungs. C. Decreased serum potassium levels. D. Rapid weight loss over a few days.

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.
