The correct statement about shoulder dystocia is

Correct Answer: A

Rationale: The correct statement about shoulder dystocia is A: It’s an impaction of the anterior shoulder after delivery of the head. This is accurate as shoulder dystocia occurs when the anterior shoulder becomes impacted behind the maternal pubic symphysis. This can lead to difficulty delivering the shoulders after the head is delivered. B is incorrect as shoulder dystocia involves the anterior shoulder, not the posterior. C is incorrect as shoulder dystocia is not related to compound presentation. D is incorrect as shoulder dystocia is an obstetric emergency that requires prompt intervention to prevent complications for both the mother and the baby.

Correct Answer: B

Rationale: The correct answer is B: Sweeping of membranes and amniotomy. 1. Sweeping of membranes involves manually separating the amniotic sac from the lower part of the uterus, stimulating the release of prostaglandins to induce labor. 2. Amniotomy is the artificial rupture of membranes, which can accelerate labor by releasing amniotic fluid and initiating contractions. 3. These methods are commonly used for surgical induction of labor due to their effectiveness and minimal invasiveness compared to other options. Incorrect choices: A: Cytotec is a medication used for labor induction, but mechanical cervical dilatation is not a standard surgical method. C: Buscopan is used for relaxation of smooth muscle and not commonly used for labor induction. D: Syntocinon is a synthetic form of oxytocin used to induce or augment labor, but it is not typically used in surgical induction methods.

Correct Answer: A

Rationale: The correct answer is A: Erb’s palsy. Excessive traction and twisting of the neck during shoulder delivery can stretch or tear the brachial plexus nerves, leading to Erb’s palsy. This results in weakness or paralysis of the arm. Radial palsy (B) involves injury to the radial nerve, not typically caused by shoulder delivery. Torticollis (C) is a condition characterized by neck muscle contracture, not caused by excessive traction during delivery. Ecchymosis (D) refers to bruising and is not directly related to neck traction during delivery. In summary, Erb’s palsy is the correct choice due to the specific nerve injury pattern associated with excessive neck traction during shoulder delivery.

Correct Answer: C

Rationale: The correct answer is C because neglected obstructed labor and high parity are well-established predisposing factors to uterine rupture. Neglected obstructed labor can cause prolonged pressure on the uterus, leading to weakening and potential rupture. High parity (having given birth multiple times) can also increase the risk of uterine rupture due to repeated stretching and strain on the uterine muscles. A, B, and D are incorrect because nulliparity (never given birth), breech presentation, multiple pregnancy, and obstetric maneuvers are not as strongly associated with uterine rupture as neglected obstructed labor and high parity. These factors may increase the risk of other complications during childbirth but are not primary predisposing factors for uterine rupture.

Correct Answer: C

Rationale: The correct answer is C because secondary post-partum hemorrhage can occur up to 6 weeks (46 days) after delivery, typically due to delayed complications like retained placental fragments or infection. Choice A is incorrect because most secondary post-partum hemorrhage occurs after the first week. Choice B is incorrect as it describes primary post-partum hemorrhage, which occurs within 24 hours of delivery. Choice D is incorrect since lochia serosa is a normal discharge present in the early post-partum period and is not specific to diagnosing secondary post-partum hemorrhage.

Correct Answer: B

Rationale: The correct answer is B, Gestational diabetes mellitus. This condition is diagnosed when a pregnant woman exhibits symptoms of diabetes and has elevated fasting blood sugar and abnormal oral glucose tolerance test results. This specific combination of symptoms and test results during pregnancy points towards gestational diabetes mellitus. A: Potential diabetes mellitus - Incorrect. The symptoms combined with abnormal test results suggest an active condition, not potential. C: Clinical diabetes mellitus - Incorrect. While the symptoms and test results indicate diabetes, the context of pregnancy suggests gestational diabetes. D: Chemical diabetes mellitus - Incorrect. This term is not commonly used in medical practice and does not specifically address the condition in the given scenario.

Correct Answer: C

Rationale: The correct answer is C: Seat belts. Flexion-distraction injuries of the thoracolumbar spine are commonly caused by seat belts due to the mechanism of injury during a motor vehicle accident. When a sudden deceleration occurs, the body is restrained by the seat belt while the spine continues to move forward, leading to hyperflexion of the spine. This results in distraction forces at the thoracolumbar junction, causing injury. Blunt trauma (choice A) can cause various types of spinal injuries but is not specifically associated with flexion-distraction injuries. Rotational injury (choice B) typically leads to injuries such as fractures or dislocations, not flexion-distraction injuries. Gunshot wounds (choice D) can cause direct spinal damage, but they do not typically result in flexion-distraction injuries.

Correct Answer: A

Rationale: The correct answer is A: Increases risk of gestational diabetes. Maternal obesity can lead to insulin resistance, increasing the likelihood of developing gestational diabetes during pregnancy. This condition can have negative effects on both the mother and the baby. B: Miscarriage is not directly linked to maternal obesity but can be influenced by other factors. C: Maternal obesity is not a direct cause of anemia during pregnancy. Anemia is usually related to iron deficiency or other factors. D: Maternal obesity is actually associated with an increased risk of preterm labor, not a reduced chance. This is due to various complications such as hypertension and preeclampsia.

Correct Answer: B

Rationale: The correct answer is B: Irritability, hypoxia, and paralysis. Intracranial injury can lead to neurological symptoms such as irritability due to brain inflammation, hypoxia from impaired oxygen delivery, and paralysis from damage to the brain or spinal cord. Limpness, bruises, and hypothermia (Option A) are not specific to intracranial injury. Hypothermia, limpness, and irritability (Option C) do not encompass the key neurological symptoms associated with intracranial injury. Hypocalcemia, paralysis, and hypoxia (Option D) include incorrect factors not typically seen in intracranial injury.
