Question 25

Edema is a common complication associated with chronic renal failure.

Chronic renal failure often leads to fluid retention in the body, resulting in edema. This occurs because the kidneys lose their ability to filter excess fluid and waste from the blood effectively.

A) Malignant hyperthermia

Malignant hyperthermia is a rare genetic condition triggered by certain anesthetics, not a complication associated with chronic renal failure. It primarily affects muscle metabolism during anesthesia and does not relate to kidney function or fluid balance.

B) Lymphoma

Lymphoma is a type of cancer that originates in the lymphatic system and is not a complication of chronic renal failure. While patients with chronic kidney issues may have an increased risk of some cancers, lymphoma is not directly linked to renal failure.

C) Ulcerative colitis

Ulcerative colitis is an inflammatory bowel disease affecting the colon and is not associated with chronic renal failure. It does not stem from kidney dysfunction and is unrelated to the renal complications that arise from chronic kidney conditions.

D) Edema

Edema is a significant complication of chronic renal failure, resulting from the kidneys' inability to eliminate excess sodium and water. This fluid retention can lead to swelling in various parts of the body, making it a direct consequence of impaired renal function.

Conclusion

Edema is definitively the correct answer as it is a well-documented complication resulting from chronic renal failure due to fluid overload. Other options, such as malignant hyperthermia, lymphoma, and ulcerative colitis, do not have a causal relationship with renal function. Thus, they fail to represent complications arising from chronic renal failure.
