A nurse is providing education to a pregnant client about the hormonal changes during pregnancy.
Which hormone is responsible for maintaining the corpus luteum and stimulating fetal growth ?
Progesterone
Estrogen
Thyroid hormones.
Prolactin
The Correct Answer is A
Progesterone is responsible for maintaining the corpus luteum and stimulating fetal growth.
Progesterone also prevents miscarriage by relaxing the uterus and maintaining the endometrium.
Choice B is wrong because estrogen is not responsible for maintaining the corpus luteum or stimulating fetal growth.
Estrogen helps develop the female sexual traits and supports the growth of the uterus and placenta.
Choice C is wrong because thyroid hormones are not responsible for maintaining the corpus luteum or stimulating fetal growth.
Thyroid hormones regulate the metabolism and energy levels of the mother and the fetus.
Choice D is wrong because prolactin is not responsible for maintaining the corpus luteum or stimulating fetal growth.
Prolactin stimulates milk production in the breasts after delivery.

Correct Answer is A
Explanation
This is because cramping and vaginal bleeding 24 hours after amniocentesis are signs of possible complications, such as injury to the baby or mother, leaking of amniotic fluid, infection, Rh sensitization, preterm labor, or miscarriage.
These complications are rare, but they can be serious and require immediate medical attention.
Choice B is wrong because administering pain medication to the patient does not address the underlying cause of the cramping and bleeding, and may delay seeking help.
Choice C is wrong because encouraging the patient to rest and elevate her legs may not prevent further complications, and may also delay seeking help.
Choice D is wrong because offering emotional support and reassurance to the patient is not enough to ensure the safety of the baby and the mother, and may give a false sense of security.
Normal ranges for amniocentesis are:
No chromosomal defects detected in the fetus and no abnormal proteins present in amniotic fluid
No signs of infection or other illness in the baby
Fetal lungs mature enough for birth if delivery is planned sooner than 39 weeks
Correct Answer is B
Explanation
This change alters the center of gravity and posture of the body because the uterus expands and shifts higher as the fetus grows during pregnancy.
This causes an increased strain on the muscles and ligaments supporting the vertebral column and leads to lower back pain.
Choice A is wrong because increased joint laxity does not alter the center of gravity and posture of the body.
It is caused by hormonal changes that loosen the ligaments throughout the body, resulting in decreased stability of the joints.
Choice C is wrong because increased muscle strain does not alter the center of gravity and posture of the body.
It is a consequence of the shift in the center of gravity and the weight gain during pregnancy, which put more pressure on the back muscles.
Choice D is wrong because decreased muscle strength does not alter the center of gravity and posture of the body.
It is not a common musculoskeletal change during pregnancy, although some women may experience fatigue or weakness due to hormonal changes or anemia.
