Correct Answer: D

Rationale: Severe shoulder pain is a common finding in clients with a ruptured ectopic pregnancy due to referred pain from diaphragmatic irritation caused by blood in the abdominal cavity. This pain is known as Kehr's sign and is often experienced in the shoulder due to irritation of the phrenic nerve. Choices A, B, and C are incorrect. A ruptured ectopic pregnancy typically presents with symptoms such as abdominal pain, vaginal bleeding, and signs of shock, rather than no alteration in menses, a fetus in the uterus, or elevated blood progesterone levels.

Correct Answer: C

Rationale: In this scenario, the symptoms of continued nausea, vomiting, scant prune-colored discharge, and a fundal height larger than expected at 4 months of gestation suggest a possible hydatidiform mole. Hyperemesis gravidarum (choice A) typically presents with severe nausea, vomiting, weight loss, and electrolyte imbalances. Threatened abortion (choice B) is characterized by vaginal bleeding with or without cramping but does not typically present with prune-colored discharge. Preterm labor (choice D) manifests with regular uterine contractions leading to cervical changes and can occur later in pregnancy.

Correct Answer: B

Rationale: Ectopic pregnancy should be suspected in clients with abrupt, sharp, right-sided lower quadrant abdominal pain and bright red vaginal bleeding, especially if they have an intrauterine device (IUD). In this case, the client's symptoms are classic for ectopic pregnancy, where the fertilized egg implants outside the uterus, commonly in the fallopian tube. Missed abortion (choice A) refers to a nonviable embryo or fetus in the uterus, which is not consistent with the client's presentation. Severe preeclampsia (choice C) is characterized by hypertension and proteinuria, not the symptoms described. Hydatidiform mole (choice D) presents with vaginal bleeding but typically lacks abdominal pain and is not related to the presence of an IUD.

Correct Answer: C

Rationale: Maternal hypotension during pregnancy is often caused by the weight of the uterus pressing on the vena cava when the client is lying on her back, which reduces blood flow to the heart. This compression can lead to a decrease in blood pressure and subsequent symptoms of hypotension. Choice A is incorrect because an increase in blood volume typically leads to increased blood pressure rather than hypotension. Choice B is incorrect as pressure from the uterus on the diaphragm is not a common cause of maternal hypotension. Choice D is incorrect because increased cardiac output would not directly cause maternal hypotension.

Correct Answer: B

Rationale: During the first few months of pregnancy, it is common for individuals to experience mixed feelings due to hormonal changes and the significant life adjustments that come with pregnancy. The nurse's response should acknowledge the client's feelings as normal and provide reassurance rather than dismissive or directive statements. By acknowledging the normalcy of these emotions, the nurse validates the client's experience and offers support during this critical time. Choices A, C, and D are less appropriate. Choice A focuses on informing the provider without addressing the client's emotions directly. Choice C disregards the client's current feelings and imposes a specific emotional response. Choice D jumps to scheduling a counseling appointment without first acknowledging the client's emotions or providing immediate support and validation.
