Correct Answer is A
Explanation
The nurse should first assess the fundus of the uterus. If the uterus is not firm (boggy), it may not be contracting well enough to compress the blood vessels and stop the bleeding. The nurse should massage the fundus until it is firm.
Correct Answer is D
Explanation
Choice A rationale
Excessive uterine enlargement is a common finding in a client with a hydatidiform mole. This is due to the overgrowth of trophoblastic tissue, which forms the placenta.
Choice B rationale
Profuse, clear vaginal discharge is not typically associated with a hydatidiform mole. The most common symptom is vaginal bleeding, which can be dark brown or bright red, and sometimes is described as looking like prune juice.
Choice C rationale
An irregular fetal heart rate is not a typical finding in a client with a hydatidiform mole, as this condition often results in a nonviable pregnancy.
Choice D rationale
A rapid decline in human chorionic gonadotropin (hCG) levels is not expected in a client with a hydatidiform mole. In fact, hCG levels are usually abnormally high in these cases.
