A nurse is caring for a pregnant woman who has gestational diabetes.
The nurse knows that the woman’s placenta produces hormones that have which of the following effects on her cells?
The placental hormones do not increase the uptake of glucose by the cells, but rather decrease it by interfering with insulin action
The placental hormones do not decrease the production of glucose by the cells, but rather increase it by stimulating gluconeogenesis and glycogenolysis in the liver
The placenta produces hormones such as human placental lactogen, growth hormone, prolactin, corticotropin-releasing hormone, and progesterone that can have a blocking effect on insulin. This is called insulin resistance and it causes glucose to build up in the blood instead of being absorbed by the cells.
The placental hormones do not decrease the breakdown of glucose by the cells, but rather increase it by stimulating lipolysis and ketogenesis in adipose tissue.
The correct answer is choice C. They increase the resistance to insulin by the cells. This is because the placenta produces hormones such as human placental lactogen, growth hormone, prolactin, corticotropin-releasing hormone, and progesterone that can have a blocking effect on insulin. This is called insulin resistance and it causes glucose to build up in the blood instead of being absorbed by the cells.
Choice A is wrong because the placental hormones do not increase the uptake of glucose by the cells, but rather decrease it by interfering with insulin action.
Choice B is wrong because the placental hormones do not decrease the production of glucose by the cells, but rather increase it by stimulating gluconeogenesis and glycogenolysis in the liver.
Choice D is wrong because the placental hormones do not decrease the breakdown of glucose by the cells, but rather increase it by stimulating lipolysis and ketogenesis in adipose tissue.
