Midwifery Exam Questions

Correct Answer: A

Rationale: The engaging diameter in a face presentation is the sub-mento vertical diameter. This is the correct answer because it represents the distance from the tip of the chin (mentum) to the highest point on the skull (vertex), which is the most critical diameter for the face to descend through the pelvis during childbirth. Choice B (Sub-mento bregmatic diameter) is incorrect because it represents the distance from the tip of the chin to the anterior fontanelle, not the highest point on the skull. Choice C (Mento vertical diameter) is incorrect because it refers to the distance from the chin to the base of the skull, not the highest point on the skull. Choice D (Sub-occipito bregmatic diameter) is incorrect because it represents the distance from the base of the skull to the anterior fontanelle, not involving the chin.

Correct Answer: A

Rationale: The correct answer is A: Acyclovir. The rationale is that sudden sensorineural hearing loss (SSHL) can sometimes be associated with viral infections, such as herpes simplex virus. Acyclovir is an antiviral medication that can potentially help treat the underlying viral infection causing SSHL. It is important to address the potential viral etiology before considering other treatments. Summary of other choices: B: Furosemide is a diuretic used to treat conditions like high blood pressure and edema, not SSHL. C: Warfarin is an anticoagulant used to prevent blood clots, not indicated for SSHL. D: Hyperbaric oxygen therapy is sometimes used for SSHL, but addressing any potential viral infection with Acyclovir would be a more appropriate initial step.

Correct Answer: D

Rationale: The correct answer is D: Prepare for reoperation. Given the patient's elevated AST and ALT levels after hepatic resection, along with abnormal prothrombin time and low albumin, there is concern for liver dysfunction. This indicates a potential complication post-surgery, such as hepatic insufficiency or failure, necessitating reoperation for further evaluation and management. Cancelling the transfer (A) would delay necessary intervention. Infusing albumin and fresh frozen plasma (B) would address only the symptoms but not the underlying cause. Repeating labs the next day (C) would not address the urgency of the situation.

Correct Answer: B

Rationale: The correct answer is B because pressure applied on the cervix by the presenting part in obstructed labor leads to edema of the vulva. This pressure causes obstruction of blood and lymphatic flow in the area, resulting in swelling and edema. Prolonged effort by the mother (choice A) would not directly cause vulvar edema. An ill-fitting presenting part (choice C) may contribute to obstruction but does not explain the mechanism of edema. Large presenting diameters (choice D) stretching the vulva would not directly cause edema without pressure on the cervix.

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.
