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.

A 3 lb weight gain in a short period, especially overnight, is indicative of fluid overload in a client with end-stage kidney disease receiving hemodialysis. Hemodialysis is performed to remove excess fluid and waste products from the body. If the client is experiencing fluid overload, it means that their body is retaining more fluid than it should, and this can lead to complications such as pulmonary edema, heart failure, and other cardiovascular problems. The nurse should identify this finding as an indication of potential fluid overload and report it to the healthcare provider for further evaluation and intervention.
