Correct Answer: D

Rationale: The correct answer is D, postpartum eclampsia. In amniotic fluid embolism, convulsions are often mistaken for postpartum eclampsia due to similar symptoms such as seizures and altered mental status. Postpartum eclampsia occurs after delivery, usually within 48 hours, while antepartum eclampsia occurs before delivery. Presence of stroke and pre-existing epilepsy are not directly related to convulsions in amniotic fluid embolism. Thus, D is the correct choice as it closely resembles the presentation of convulsions in amniotic fluid embolism.

Correct Answer: D

Rationale: The correct answer is D: His symptoms occur in 5 to 10% of people after ulcer surgery. This is the correct answer because the patient's symptoms of decreased capacity for intake and nausea after eating are common post-operative complications following ulcer surgery. By stating this fact to the patient, the AGACNP is providing reassurance that these symptoms are not unusual. Explanation for why the other choices are incorrect: A: Endoscopy is not necessary at this point since the symptoms described by the patient are known post-operative complications and do not indicate an urgent need for endoscopy. B: While gastroparesis can be a complication of ulcer surgery, there is no information in the case to suggest that the patient has chronic gastroparesis. C: Jumping to the conclusion that medication is unlikely to help and another surgery may be needed is premature and not supported by the information provided in the case.

Correct Answer: B

Rationale: The correct answer is B: Hyperbaric oxygen. Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized room, which can help reduce gas cysts in the gastrointestinal tract by increasing oxygen delivery to tissues. This promotes healing and reduces symptoms associated with pneumatosis. A: Several days of oxygen by face mask is not as effective as hyperbaric oxygen therapy in treating pneumatosis, as it does not provide the same level of pressurized oxygen delivery to tissues. C: Surgical resection may be considered in severe cases of pneumatosis where conservative treatments have failed, but it is not the first-line treatment option. D: Treatment of underlying disease is important in managing pneumatosis, but it may not directly address the gas cysts themselves. Hyperbaric oxygen therapy specifically targets the gas cysts to alleviate symptoms.

Correct Answer: C

Rationale: The correct answer is C because neglected obstructed labor and high parity are well-established predisposing factors to uterine rupture. Neglected obstructed labor can cause prolonged pressure on the uterus, leading to weakening and potential rupture. High parity (having given birth multiple times) can also increase the risk of uterine rupture due to repeated stretching and strain on the uterine muscles. A, B, and D are incorrect because nulliparity (never given birth), breech presentation, multiple pregnancy, and obstetric maneuvers are not as strongly associated with uterine rupture as neglected obstructed labor and high parity. These factors may increase the risk of other complications during childbirth but are not primary predisposing factors for uterine rupture.

Correct Answer: B

Rationale: The correct answer is B: Placental bed. Malaria parasites hide in the placental bed during pregnancy to avoid detection by the immune system. This location provides a safe haven for the parasites to survive and replicate without being cleared by the mother's immune response. The placental bed offers a rich blood supply and a favorable environment for the parasites to thrive. Incorrect choices: A: Bone marrow - Malaria parasites do not typically hide in the bone marrow during pregnancy. C: Fetal circulation - Malaria parasites do not hide in the fetal circulation; they primarily reside in the placental bed. D: Uterine muscle - Malaria parasites do not hide in the uterine muscle; the placental bed is the main site of sequestration during pregnancy.
