Correct answer is option C – normal to low urine specific gravity.

Urine specific gravity is a parameter use to compare the density of urine to the density of water. It is use to determine how well the kidneys dilute urine.

High specific urine gravity means that the client is highly dehydrated and a low to normal urine specific gravity shows that a client has had excessive fluid intake as seen in the client in the question above.

Urine osmolality is used to measure the number of dissolved particles per unit of water in urine. Large values indicate concentrated urine and low values indicate diluted urine.

Urine PH simply analyses the acidity or alkalinity of urine sample.

Normal to low urine specific gravity

Water diuresis causes low urine specific gravity. low urine osmolarity. and a normal to elevated serum sodium level.Option A: High specific gravity indicates dehydration. Hypernatremia signals acidosis and shock.Option D: Elevated urine pH can result from potassium deficiency. a high-protein diet. or uncontrolled diabetes.
