Question

A client is admitted with a head injury. The nurse identifies that the client's urinary catheter is draining large amounts of clear, colorless urine. Which cause is suspected by the nurse?

a. Increased serum glucose
b. Deficient renal perfusion
c. Inadequate antidiuretic hormone ADH secretion
d. Excess amounts of intravenous IV fluid

Answer 1

The nurse suspects inadequate secretion of antidiuretic hormone (ADH), leading to diabetes insipidus, as the cause for the client's large amounts of clear, colorless urine following a head injury. so, option C is the correct answer.

Step-by-step explanation:

When a client is admitted with a head injury and the nurse observes that their urinary catheter is draining large amounts of clear, colorless urine, this could be a symptom of inadequate antidiuretic hormone (ADH) secretion, commonly associated with a condition known as diabetes insipidus. This condition results in the kidneys not reabsorbing enough water, leading to the excretion of large volumes of dilute urine, known as polyuria. Causes of polyuria include diabetes mellitus, diseases of the central nervous system, and diabetes insipidus, where there is a deficiency of ADH.

Diabetes insipidus is characterized by chronic underproduction of ADH, which reduces the number of water channels in the kidney's collecting ducts, thereby reducing water absorption and resulting in polyuria. Excessive urine production could also be a result of other factors such as excess caffeine or alcohol intake, certain drugs such as diuretics, kidney disease, or excessive water intake.
