A nurse is caring for a client who was admitted with type 2 diabetes mellitus. Which of the following findings indicates hyperglycemia?

Choice A Reason:
 Absence of Chvostek's sign is a wrong indication. Chvostek's sign is a twitching of facial muscles in response to tapping the facial nerve and is typically associated with low blood calcium levels (hypocalcemia). It's not directly related to hyperglycemia or high blood sugar levels. Hyperglycemia refers to high blood sugar levels, commonly associated with diabetes mellitus. 
Choice B Reason:
 Presence of Kussmaul respirations is a right indication. Kussmaul respirations are deep, rapid, and labored breathing patterns often seen in individuals with diabetic ketoacidosis (DKA), a severe complication of diabetes characterized by significantly high blood sugar levels and the presence of ketones in the blood and urine. This type of breathing pattern is the body's attempt to compensate for the acidic state caused by high blood sugar and the buildup of ketones.
Choice C Reason:
 Presence of diaphoresis is a wrong indication. Diaphoresis refers to excessive sweating, which can occur due to various reasons such as physical activity, heat, stress, or certain medical conditions. While hyperglycemia can cause symptoms like increased thirst and frequent urination, diaphoresis alone is not a specific indicator of high blood sugar levels.
Choice D Reason:
Absence of urinary ketones is a wrong indication. The presence of urinary ketones indicates the body is breaking down fat for energy, which commonly occurs during periods of insufficient insulin (such as in hyperglycemia or diabetic ketoacidosis). However, the absence of urinary ketones doesn't necessarily rule out hyperglycemia. It's possible for hyperglycemia to be present without ketones in the urine, especially in the early stages or when the body is still managing blood sugar levels without significant ketone production.
