Midwifery Exam Questions

Correct Answer: C

Rationale: The correct answer is C because radiation and substances of abuse are known teratogenic causes of congenital abnormalities. Radiation exposure can lead to genetic mutations and developmental issues in the fetus. Substances of abuse like alcohol, tobacco, and illicit drugs can also negatively impact fetal development. A: Medical conditions and pesticides may have negative effects on pregnancy outcomes, but they are not typically classified as teratogenic causes of congenital abnormalities. B: Prescription drugs can be teratogenic in some cases, but not all prescription drugs have harmful effects on fetal development. Chromosomes are not typically considered teratogenic causes. D: Disordered genes can lead to congenital abnormalities, but they are not classified as teratogenic causes. Medical conditions are not universally teratogenic.

Correct Answer: C

Rationale: The correct answer is C: Extraplacental haemorrhage. Incidental antepartum haemorrhage refers to bleeding from a source other than the placenta, such as the cervix or vagina, before delivery. Intraplacental haemorrhage (choice A) refers to bleeding within the placenta itself, not outside it. Intrapartum haemorrhage (choice B) occurs during labor and delivery, not before. Preterm haemorrhage (choice D) is not a specific term used to describe antepartum bleeding. Therefore, the correct term for antepartum bleeding from a non-placental source is extraplacental haemorrhage.

Correct Answer: B

Rationale: The correct answer is B: Acute pancreatitis. The clinical presentation of sudden, severe upper abdominal pain not related to food intake, along with the patient's position (lying on right side with hips and knees flexed), and presence of involuntary guarding suggest acute pancreatitis. The elevated white blood cell count indicates an inflammatory process. Dissecting aortic aneurysm (A) typically presents with abrupt, severe chest or back pain radiating to the abdomen, with signs of shock. Perforated peptic ulcer (C) presents with sudden, severe abdominal pain often related to food intake, with signs of peritonitis. Mallory-Weiss tear (D) presents with hematemesis after forceful or prolonged vomiting.

Correct Answer: A

Rationale: The correct answer is A: Wernicke's encephalopathy. Hyperemesis gravidarum is severe nausea and vomiting during pregnancy. Wernicke's encephalopathy is a neurological complication due to thiamine deficiency, which can occur in severe cases of vomiting, leading to impaired brain function. Sheehan's syndrome is a complication of postpartum pituitary necrosis. Maurice encephalitis is a fictional term not related to this context. Antepartum bleeding is not a typical complication of hyperemesis gravidarum. Therefore, the correct answer is A due to the potential neurological impact of severe vomiting on thiamine levels.

Correct Answer: D

Rationale: The correct answer is D: Elective lymph node dissection. This is because elective lymph node dissection helps to remove potentially cancerous lymph nodes, aiding in staging and ensuring complete tumor removal, thus improving the chances of curative surgery. En bloc resection (A) is important but may not always be feasible in fixed tumors. Adjuvant therapies (B) are used after surgery, not as the primary approach. Neoadjuvant therapies (C) are given before surgery to shrink tumors, not specifically for fixed tumors.
