Placental parasitation is associated with

Correct Answer: D

Rationale: Placental parasitation is associated with Malaria prenatally because the Plasmodium parasite can infect the placenta through the bloodstream, leading to severe complications for both the mother and the fetus. This infection can result in low birth weight, preterm birth, and even stillbirth. Candidiasis, Tuberculosis, and Multiple gestation are not directly associated with placental parasitation. Candidiasis is a fungal infection, Tuberculosis is a bacterial infection, and Multiple gestation refers to carrying more than one fetus during pregnancy. Therefore, the correct answer is D, Malaria prenatally, due to the direct impact of Plasmodium parasite on the placenta and its implications on pregnancy outcomes.

Correct Answer: D

Rationale: The correct answer is D because the placenta performs multiple crucial roles in pregnancy. Firstly, it produces hormones essential for maintaining the pregnancy. Secondly, it provides nutrients and oxygen to the fetus for growth and development. Lastly, it removes waste products from the fetus to ensure a healthy environment. Choices A, B, and C individually do not cover all the functions of the placenta, making them incorrect. Selecting option D acknowledges the comprehensive functions of the placenta during pregnancy.

Correct Answer: A

Rationale: The correct answer is A: Hypogastrinemia and acid hyposecretion. Gastrinoma is a tumor that secretes excessive gastrin, leading to hypergastrinemia and increased acid secretion. However, due to a negative feedback mechanism, chronic exposure to high gastrin levels can cause downregulation of gastrin receptors on parietal cells, leading to decreased acid secretion. Therefore, in gastrinoma, despite high gastrin levels, acid secretion may be reduced due to this negative feedback loop. Choices B, C, and D are incorrect because they do not align with the expected relationship between gastrin levels and acid secretion in gastrinoma.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): 1. The patient's symptoms of decreased capacity for intake and nausea after eating suggest gastroparesis, a common complication post-ulcer surgery. 2. Given the history of complicated peptic ulcer disease and prior surgery, medication may be ineffective, necessitating potential reoperation. 3. The AGACNP advises that another surgery may be needed, indicating that medication alone may not suffice to address the issue. Summary of Incorrect Choices: A: Endoscopy is not necessary at this point as the symptoms are likely indicative of a functional issue rather than a structural problem. B: While gastroparesis can occur post-ulcer surgery, the patient's symptoms are more suggestive of gastroparesis rather than chronic gastroparesis as a known complication. D: The frequency of occurrence of symptoms after ulcer surgery is not relevant to the current management of the patient's symptoms.

Correct Answer: D

Rationale: The correct answer is D, "All of the above." Fetal macrosomia, malpresentation, and pelvic abnormalities are all known causes of obstructed labor. Fetal macrosomia refers to a large baby, which can lead to difficulty in passing through the birth canal. Malpresentation occurs when the baby is not positioned optimally for delivery, such as breech or transverse positions. Pelvic abnormalities, such as a contracted pelvis, can impede the baby's passage during labor. Therefore, selecting option D is appropriate as it encompasses all the major causes of obstructed labor. Choices A, B, and C are not individually comprehensive enough to cover all potential causes of obstructed labor.

Correct Answer: B

Rationale: Step 1: TB can be transmitted from an infected mother to her child during labor. Step 2: The TB bacteria can be present in the mother's respiratory secretions. Step 3: During labor, the baby can inhale these bacteria and contract TB. Step 4: Therefore, the statement that mother-to-child transmission of TB organisms never occurs during labor is FALSE. Summary: Option B is correct because it accurately reflects the possibility of mother-to-child transmission of TB during labor. Option A is incorrect as it contradicts the factual information. Options C and D are not applicable as they provide no information.

Correct Answer: C

Rationale: The correct answer is C: Hyperemesis gravidarum. This condition is characterized by severe nausea, vomiting, weight loss, dehydration in pregnancy. It is more severe than typical morning sickness (choice A) and is not specific to multiple gestation (choice B). Hypertensive disorders (choice D) typically present with high blood pressure, proteinuria, and edema, not just nausea and vomiting. Hyperemesis gravidarum requires medical intervention due to potential complications from dehydration and malnutrition.

Correct Answer: A

Rationale: Rationale: Breech presentation increases risks during childbirth. Prolonged labor is common due to the position of the baby. Umbilical cord prolapse occurs when the cord slips through the cervix before the baby, leading to oxygen deprivation. Shoulder dystocia happens when the baby's shoulders get stuck during delivery. Choice A is correct as it directly relates to complications of breech presentation. Choices B, C, and D are incorrect as they do not specifically address the complications associated with breech presentation. Cesarean delivery is often recommended for breech presentation to avoid complications. Uterine rupture is a rare but severe complication that is not directly caused by breech presentation. Preeclampsia, gestational diabetes, and low birth weight are not commonly associated with breech presentation. Therefore, choice A is the correct answer.

Correct Answer: D

Rationale: The correct answer is D because hypoplastic left heart syndrome involves underdevelopment of the left ventricle, aortic valve, and aortic arch. The left ventricle is typically small and unable to adequately pump blood to the body. The aortic valve is often malformed, leading to difficulties in blood flow from the heart to the body. Additionally, the aortic arch may be narrow or underdeveloped, further impacting blood circulation. Choice A is incorrect as it includes the pulmonary veins, which are not typically affected in hypoplastic left heart syndrome. Choice B is incorrect as it focuses on the left atrium and pulmonary vessels, which are not the primary structures affected in this condition. Choice C is incorrect as it mentions the aorta arch, venacava, and right atrium, which are not primarily associated with hypoplastic left heart syndrome.
