Final answer:
Increased urination is normal after delivery due to physiological changes such as increased bladder pressure and the processing of additional fluids. The body is adjusting and eliminating excess fluid, which should normalize as the uterus returns to its pre-pregnancy size.
Step-by-step explanation:
The nurse's best response to a client who states "I have been urinating so much" 24 hours after delivery is: Increased urination is normal after delivery. After childbirth, frequent urination can occur due to several physiological changes during pregnancy, including the increased pressure on the bladder from the uterus and additional blood and fluid volume that needs to be processed by the kidneys after birth. It's also part of the body's way of eliminating excess fluid accumulated during pregnancy. As the uterus shrinks back to its pre-pregnancy size, a process known as involution, this pressure decreases, and urination patterns should begin to normalize. However, if there are accompanying symptoms such as burning or urgency, these could indicate a urinary tract infection and would require further medical attention.
