Midwifery Exam Questions

Correct Answer: A

Rationale: The correct answer is A: TRUE. This is because BCG vaccination for newborns is recommended even if the mother is smear-negative for tuberculosis, as it helps protect the newborn from severe forms of TB. Smear status of the mother does not impact the need for BCG vaccination in the neonate. Choice B is incorrect as it falsely implies that BCG should not be given in this scenario. Choices C and D are not applicable as they do not provide any information.

Correct Answer: B

Rationale: The correct answer is B: Trial of scar. This term specifically refers to the process of attempting a vaginal birth after a previous caesarean section. It involves monitoring the previous cesarean scar for any signs of complications during labor. A: Spontaneous vaginal delivery refers to giving birth vaginally without any previous cesarean section. C: Spontaneous vertex delivery simply describes the position of the baby's head during birth. D: Trial of birth is not a commonly used term in obstetrics and does not specifically relate to VBAC.

Correct Answer: A

Rationale: The correct answer is A: Prevent alveoli of the lungs from collapsing. Surfactant reduces surface tension in the alveoli, preventing them from collapsing during exhalation and maintaining lung compliance. B, C, and D are incorrect because surfactant primarily affects lung mechanics, not the initiation of breathing, maturity of the respiratory center, or immediate regulation of breathing upon birth.

Correct Answer: B

Rationale: The correct answer is B: CT scan without contrast. A CT scan is the most useful imaging study in assessing for findings consistent with a history of abuse in this patient. CT scan is preferred for acute trauma to the head as it provides detailed images of the brain, skull, and facial bones. It can detect acute hemorrhages, fractures, or other signs of trauma. In this case, the patient's presentation with periorbital ecchymosis and facial swelling raises suspicion for traumatic injury, which can be assessed effectively with a CT scan. Radiographs (choice A) are not as sensitive as CT scans in detecting subtle fractures or soft tissue injuries in the head and face. MRI (choice C) is not typically used in acute trauma assessment and may not provide timely information needed in this case. PET scan (choice D) is not indicated for evaluating traumatic head injuries and is more commonly used for assessing metabolic and functional activity in the body.

Correct Answer: C

Rationale: The correct answer is C, Couvelaire uterus. This condition is characterized by a bruised and edematous appearance of the uterus due to severe placental abruption. The rationale is that a Couvelaire uterus specifically refers to this presentation, while the other choices do not. A: Wernicke's encephalopathy is a neurological disorder caused by thiamine deficiency. B: Uterine prolapse is the descent or herniation of the uterus into or beyond the vagina. D: Asherman's syndrome involves intrauterine adhesions leading to menstrual irregularities.
