Midwifery Exam Practice Questions

Correct Answer: C

Rationale: The correct answer is C: Premature rupture of membranes. Oligohydramnios is a condition characterized by low levels of amniotic fluid which can be caused by the premature rupture of membranes, leading to the leakage of amniotic fluid. This condition can result in various complications such as fetal growth restriction and compression of the umbilical cord. Maternal hypertension (choice A) is not a direct cause of oligohydramnios. Multiple gestations (choice B) may lead to polyhydramnios (excessive amniotic fluid) rather than oligohydramnios. Fetal macrosomia (choice D) is associated with increased amniotic fluid levels rather than decreased levels seen in oligohydramnios.

Correct Answer: D

Rationale: The correct answer is D. TB in pregnancy can lead to premature labor due to the fever experienced. Fever increases the risk of premature labor by triggering uterine contractions. Poor maternal appetite (A) and severe anemia (B) may impact the mother's health but are not directly linked to premature labor. Adverse reactions of anti-TB drugs (C) could potentially affect the mother's health but are not a direct cause of premature labor.

Correct Answer: A

Rationale: Placenta praevia is classified into four types based on the degree of coverage of the cervix by the placenta. Complete placenta praevia, where the internal os is completely covered by the placenta, is referred to as Type 4. This is the correct answer as it accurately describes the specific condition. Choices B, C, and D are incorrect as they do not correspond to the classification system for placenta praevia.

Correct Answer: B

Rationale: The correct answer is B: Rotational injury. Flexion-distraction injuries of the thoracolumbar spine are often caused by rotational forces that occur during accidents such as motor vehicle collisions or falls. These forces lead to the spine being twisted, causing separation of the vertebrae. Blunt trauma (A) can cause various spinal injuries but is not specific to flexion-distraction injuries. Seat belts (C) are designed to prevent spinal injuries by restraining the body during a collision. Gunshot wounds (D) can cause spinal cord injuries but are not commonly associated with flexion-distraction injuries of the thoracolumbar spine.

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.
