A nurse is caring for a client with a urine specific gravity of less than 1.005, polyuria, and nocturia. The nurse recognizes that which of the following physiologic findings is the likely cause?
Increased insulin production
Increased adrenocorticotropic hormone (ACTH)
Low levels of T3, T4
Insufficient antidiuretic hormone (ADH)
The Correct Answer is D
A. Increased insulin production would not cause polyuria and low specific gravity urine; rather, hyperglycemia from lack of insulin can cause high specific gravity due to glucose in urine.
B. Increased ACTH affects cortisol production but is not directly related to urine concentration or polyuria.
C. Low T3 and T4 levels are associated with hypothyroidism, which typically does not cause polyuria or decreased specific gravity.
D. Insufficient ADH, as seen in diabetes insipidus, leads to the inability to concentrate urine, resulting in a low specific gravity, polyuria, and nocturia due to excessive water loss.

Correct Answer is D
Explanation
A. Keeping the room brightly lit can be overstimulating and may increase ICP; therefore, a calm, dimly lit environment is preferable.
B. Encouraging coughing and deep breathing exercises could increase ICP and should be avoided unless specifically indicated.
C. Placing the client in a supine position is not recommended for clients with increased ICP; they should typically be positioned with the head elevated to promote venous drainage.
D. Implementing seizure precautions is critical as head injuries can lead to seizures, and ensuring the client's safety is a priority.
Correct Answer is C
Explanation
A. Diplopia is a concerning symptom but does not indicate immediate deterioration in neurological status like a change in GCS does.
B. Ataxia is also significant but is less acute than a drop in GCS score.
C. A change in the Glasgow Coma Scale score from 13 to 11 indicates a worsening level of consciousness and necessitates immediate reporting, as it may suggest increased intracranial pressure or other complications.
D. A decrease in heart rate from 76 to 69 bpm is not significant enough in the context of TBI to warrant immediate reporting, as it remains within a normal range.
