Question

Which renal system adaptation is an anticipated anatomic change of pregnancy?

a. Increased urinary output makes pregnant women less susceptible to urinary infections.
b. Increased bladder sensitivity and then compression of the bladder by the enlarging uterus result in the urge to urinate even when the bladder is almost empty.
c. Renal (kidney) function is more efficient when the woman assumes a supine position.
d. Using diuretic agents during pregnancy can help keep kidney function regular.

Answer 1

The anticipated renal system adaptation in pregnancy is the increased bladder sensitivity and compression by the enlarging uterus, which leads to increased frequency of urination. Increased urine production due to processing maternal and fetal wastes is also a characteristic change. These adaptations meet the demands of pregnancy and fetal waste management.

Step-by-step explanation:

Renal System Adaptation in Pregnancy

The anticipated anatomic change of pregnancy in the renal system is increased bladder sensitivity and then compression of the bladder by the enlarging uterus, which results in the frequent urge to urinate, even when the bladder is almost empty. During pregnancy, there is also an increase in urine production, as the maternal urinary system needs to process both maternal and fetal wastes. This leads to a higher total volume of urine. It's important to note that assuming a supine position does not make renal function more efficient, and using diuretic agents is not recommended to maintain kidney function during pregnancy.

Infection susceptibility during pregnancy is actually increased due to the changes in urinary flow and potential stasis, not decreased. In the context of increased blood volume and changes in circulatory and respiratory systems, these adaptations are critical for managing the increased demands placed on the woman’s body to support fetal development and waste removal.
