Cardiovascular Changes in pregnancy
Cardiovascular Changes in pregnancy ( 4 Questions)
A nurse is educating a pregnant client about the musculoskeletal changes during pregnancy.
Which hormone is primarily responsible for increasing joint laxity?
Relaxin is primarily responsible for increasing joint laxity during pregnancy. Relaxin is a hormone that is produced by the corpus luteum and the placenta, and it helps to soften and widen the cervix and the pubic symphysis for childbirth. Relaxin also affects other joints and ligaments throughout the body, making them more flexible and prone to injury.
Progesterone is not directly involved in joint laxity, although it does have other effects on the musculoskeletal system, such as increasing bone resorption and decreasing muscle strength.
Estrogen is not directly involved in joint laxity, although it does have other effects on the musculoskeletal system, such as increasing bone formation and modulating pain perception.
Human chorionic gonadotropin (hCG) is not directly involved in joint laxity, although it does have other effects on the musculoskeletal system, such as stimulating thyroid function and increasing fluid retention.

Choice B is wrong because progesterone is not directly involved in joint laxity, although it does have other effects on the musculoskeletal system, such as increasing bone resorption and decreasing muscle strength.
Choice C is wrong because estrogen is not directly involved in joint laxity, although it does have other effects on the musculoskeletal system, such as increasing bone formation and modulating pain perception.
Choice D is wrong because human chorionic gonadotropin (hCG) is not directly involved in joint laxity, although it does have other effects on the musculoskeletal system, such as stimulating thyroid function and increasing fluid retention.
Normal ranges for these hormones vary depending on the stage of pregnancy, but generally they increase throughout gestation and peak near term.
