Correct Answer: D

Rationale: The correct answer is D: Hyperbaric oxygen. SSHL is a medical emergency that requires prompt intervention. Hyperbaric oxygen therapy increases oxygen delivery to the inner ear, potentially reversing the hearing loss. Acyclovir (A) is used for viral infections, not SSHL. Furosemide (B) is a diuretic used for treating fluid retention, not SSHL. Warfarin (C) is an anticoagulant and is not indicated for SSHL. In summary, hyperbaric oxygen is the appropriate choice for managing SSHL due to its potential to improve oxygen delivery to the inner ear.

Correct Answer: A

Rationale: The correct answer is A: Increased MCV. Following splenectomy, there is a compensatory increase in red blood cell production, leading to an increase in Mean Corpuscular Volume (MCV) due to the release of larger, younger red blood cells into circulation. This is known as stress erythropoiesis. Summary: B: Increased Hgb - Hgb levels may not necessarily increase post-splenectomy as it depends on factors such as bleeding or hydration status. C: Increased platelets - Platelet count is not expected to increase immediately post-splenectomy. D: Increased albumin - Albumin levels are not directly influenced by splenectomy for idiopathic thrombocytopenia purpura.

Correct Answer: B

Rationale: The correct answer is B: Placental insufficiency. Prolonged pregnancy can lead to decreased placental function, resulting in inadequate oxygen and nutrients for the fetus. This can lead to complications such as intra-uterine growth restriction and fetal distress. Option A (Intra-uterine oligohydramnios) is a consequence of decreased amniotic fluid levels but not directly associated with prolonged pregnancy. Option C (Fetal post-maturity syndrome) refers to the complications seen in a post-term newborn, not maternal risks. Option D (Large for gestational age baby) is a consequence of prolonged pregnancy but does not directly impact maternal health.

Correct Answer: C

Rationale: The correct answer is C: Wrinkled, peeling skin. Post-maturity syndrome occurs when a pregnancy extends beyond 42 weeks, causing the baby to lose the protective layer of vernix caseosa, leading to dry, peeling skin. Closed eyes and being unusually alert (A) are not specific to post-maturity syndrome. Long, frail fingernails (B) are not a typical characteristic of post-maturity. Excess vernix caseosa (D) is actually a characteristic of a premature baby, not a post-mature one.

Correct Answer: C

Rationale: The correct answer is C: Not more than two previous caesarean section scars. This is because a trial of scar refers to a trial of labor in a woman who has had previous cesarean sections. The guideline typically recommends that a trial of scar should be considered in women with no more than two previous cesarean section scars to reduce the risk of uterine rupture. Choices A, B, and D are incorrect because the estimated fetal weight, availability of a level one hospital, and pelvis size are not specific criteria used to determine eligibility for a trial of scar.
