Final answer:
The bladder is often hypotonic due to trauma during the dehydration stage and/or the administration of hypertonic solutions that may decrease sensations.
Step-by-step explanation:
The bladder is often hypotonic due to trauma during the dehydration stage and/or the administration of hypertonic solutions that may decrease sensations. Dehydration can lead to hypotonicity in the bladder because it results in a loss of body water, causing fluids in the body to become more concentrated. The administration of hypertonic solutions increases the osmotic pressure in the blood, leading to fluid shifting from the tissues into the blood and subsequently causing a net loss of body water, including in the bladder.
