Answer to Question 1

D
By weighing the dressing before it is applied and after it is removed, the nurse can accurately determine the amount of drainage. Weighing the patient daily would evaluate his overall fluid balance but is not sensitive to fluid loss through the wound. Marking a circle around the wound is useful for determining the extent of drainage seeping out of a wound but it does not provide information on how much fluid is draining.

Answer to Question 2

A
Excess intake of hypotonic solutions (e.g., several large bottles of water) will result in hyponatremia, the symptoms described by this patient. Sports drinks contain electrolytes lost through perspiration, so this would not explain the patient's symptoms, indicating hyponatremia. Steroid administration can result in hypokalemia, but the patient's symptoms do not match the symptoms of hypokalemia, so this is not a good explanation. The statement about diabetes does not provide information relevant to the patient's symptoms or to the situation.
