Which patient is most likely to develop chronic kidney disease (CKD) and should be taught preventive measures by the nurse?

Among the given laboratory test results for a client with recently diagnosed hypertension, the most important result to communicate to the health care provider is option (A), "Serum creatinine of 2.8 mg/dL."

Serum creatinine is a measure of kidney function, and a value of 2.8 mg/dL indicates elevated creatinine levels. Elevated serum creatinine is a concerning finding, as it suggests decreased kidney function or kidney impairment. Hypertension can have a significant impact on the kidneys, and kidney damage is a common complication of uncontrolled high blood pressure.

The kidneys play a crucial role in regulating blood pressure by excreting waste products and excess fluids from the body. When kidney function is compromised due to hypertension, it can further worsen the blood pressure control, leading to a vicious cycle of kidney damage and worsening hypertension.

Option (B), "Serum hemoglobin of 14.7 g/dL," is within the normal range and does not indicate an immediate concern related to the client's hypertension.

Option (C), "Blood glucose level of 96 mg/dL," is also within the normal range for blood glucose and may not be directly related to the client's hypertension.

Option (D), "Serum potassium of 4.5 mEq/L," is within the normal range. While potassium levels are essential to monitor, they are not the most critical concern compared to kidney function in this context.

The elevated serum creatinine level suggests a potential complication of hypertension, namely kidney damage or decreased kidney function. Therefore, it is essential to communicate this finding promptly to the health care provider for further evaluation and appropriate management to address the client's kidney health and optimize blood pressure control.

Hemodialysis is a treatment used to remove waste products and excess fluids from the blood in individuals with kidney failure or chronic kidney disease. The primary purpose of hemodialysis is to filter and clear the blood of waste products that the kidneys can no longer remove adequately. As a result, one of the key indicators that hemodialysis is having the desired effect is a decrease in serum creatinine levels. Creatinine is a waste product that builds up in the blood when the kidneys are not functioning properly. A decrease in serum creatinine indicates that the dialysis treatment is effectively removing waste products from the blood.

Weight loss is also a positive sign after hemodialysis since it indicates that excess fluid is being removed from the body. In individuals with kidney failure, the kidneys cannot adequately remove extra fluid, leading to fluid retention and weight gain. Hemodialysis helps to eliminate this excess fluid, leading to weight loss and reducing the risk of fluid overload-related complications.

The other options listed (decreased hematocrit and diuresis, increased potassium level and improved appetite, and decreased white blood cell count and diaphoresis) are not direct indicators of the effectiveness of hemodialysis in removing waste products and excess fluid from the blood.
