A nurse in an emergency department is assessing a client who has a basilar skull fracture and serosanguineous nasal discharge following a motor vehicle crash. Which of the following findings should the nurse identify as reliable for determining that the discharge is cerebrospinal fluid?

Choice A rationale:

Hemoptysis, which is the coughing up of blood, is not typically associated with a urinary tract infection (UTI). It is more commonly related to respiratory or pulmonary issues.

Choice B rationale:

Hematuria, the presence of blood in the urine, is a common finding in a UTI. Inflammation and infection in the urinary tract can lead to the presence of blood cells in the urine.

Choice C rationale:

Hyperglycemia, an elevated blood glucose level, is not directly related to a UTI. It may be seen in individuals with diabetes, but it is not a typical finding in a UTI.

Choice D rationale:

Hypocalcemia, a low level of calcium in the blood, is not a characteristic finding in a UTI. UTIs primarily affect the urinary system and do not directly involve calcium metabolism.

Choice A rationale:
Poor skin turgor is a sign of dehydration and is not specifically related to hypoglycemia. It is assessed by pinching the skin on the back of the hand and observing how quickly it returns to its normal position.
Choice B rationale:
Fruity breath odor is associated with diabetic ketoacidosis (DKA), a complication of uncontrolled diabetes, not hypoglycemia. It is caused by the presence of ketones in the breath due to the breakdown of fats for energy in the absence of adequate insulin.
Choice C rationale:
Kussmaul respirations are deep, rapid, and labored breathing patterns seen in diabetic ketoacidosis (DKA), not in hypoglycemia. They are the body's attempt to blow off excess carbon dioxide and acid from the blood.
Choice D rationale:
Irritability is a common manifestation of hypoglycemia. Low blood glucose levels can affect brain function, leading to mood changes, irritability, and nervousness.
