In overhydration, what would be the levels of ADH (high, normal, or low) and what would be the osmolarity of the urine?

ADH - high; 600 mOsm (urine)

ADH - high; 100 mOsm (urine)

ADH - low; 600 mOsm (urine)

ADH - low; 100 mOsm (urine)

ADH - low; 100 mOsm (urine)

In overhydration, ADH would be very low and the cells of the collecting duct would be relatively impermeable to water and urea. Thus, the final urine would be dilute, having an osmolarity of about 100 mOsm.
