Question 1
A 32-year-old primigravida at 36 weeks gestation presents with sudden onset severe epigastric pain, headache, and blurred vision. Her blood pressure is 180/110 mmHg. Laboratory investigations reveal proteinuria (3+), elevated liver enzymes (AST 150 U/L, ALT 120 U/L), and thrombocytopenia (platelet count 80,000/Β΅L). Which of the following statements is/are CORRECT regarding her condition and immediate management?
A. Intravenous magnesium sulfate is indicated for seizure prophylaxis.
B. The most appropriate definitive management is immediate induction of labor or Caesarean section.
C. Fluid restriction to 80 ml/hour should be initiated to prevent pulmonary edema.
D. Oral nifedipine is the first-line antihypertensive agent of choice in this acute setting.
Textbook Explanation Highlight:
This patient presents with severe preeclampsia complicated by HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelet count). Statement 1 is correct: Intravenous magnesium sulfate is the cornerstone for seizure prophylaxis in severe preeclamp...
Question 2
A 28-year-old G2P1 at 10 weeks gestation, with a history of gestational diabetes in her previous pregnancy, is undergoing her first antenatal visit. She expresses concern about preventing recurrence. Which of the following statements regarding her current antenatal care and management is INCORRECT?
A. She should be screened for pre-existing diabetes with an HbA1c at this initial visit.
B. Early dietary and lifestyle modifications are crucial from the first trimester.
C. A 75-gram oral glucose tolerance test (OGTT) should be performed between 24 and 28 weeks of gestation.
D. Routine first-trimester screening for chromosomal anomalies should be deferred due to her high-risk status for gestational diabetes.
Textbook Explanation Highlight:
Statement 1 is correct: Women with a history of GDM are at high risk for type 2 diabetes and should be screened for overt diabetes (e.g., HbA1c or fasting glucose) at the initial antenatal visit. Statement 2 is correct: Early intervention with diet a...
Question 3
A 30-year-old primigravida at 18 weeks gestation presents with severe nausea, vomiting, and dehydration requiring hospitalization. Ultrasonography reveals a 'snowstorm' appearance with a markedly enlarged uterus for gestational age and no fetal pole. Her beta-human chorionic gonadotropin (Ξ²-hCG) level is significantly elevated (>100,000 mIU/mL). Which of the following interventions is CONTRAINDICATED as initial management?
A. Intravenous fluid resuscitation with electrolyte correction.
B. Administration of antiemetics.
C. Immediate suction evacuation and curettage.
D. Administration of oxytocin to hasten uterine evacuation prior to cervical dilation.
Textbook Explanation Highlight:
This patient presents with symptoms and ultrasound findings highly suggestive of a hydatidiform mole (gestational trophoblastic disease). Statements 1, 2, and 3 are appropriate initial management steps. Fluid resuscitation and antiemetics address her...
Question 4
Regarding the physiological changes in pregnancy, which of the following statements is/are CORRECT?
A. Plasma volume increases by approximately 50%, while red blood cell mass increases by 20-30%, leading to physiological anemia of pregnancy.
B. The cardiac output increases by 30-50% mainly due to an increase in heart rate, with a negligible contribution from stroke volume.
C. Glomerular filtration rate (GFR) increases by 50% during pregnancy, resulting in decreased serum creatinine and BUN levels.
D. Progesterone causes relaxation of smooth muscle throughout the gastrointestinal and urinary tracts, predisposing to constipation and vesicoureteral reflux.
Textbook Explanation Highlight:
Statement 1 is correct. Plasma volume increases significantly (40-50%), while red blood cell mass increases to a lesser extent (20-30%), causing a dilutional effect, known as physiological anemia of pregnancy. Statement 2 is incorrect. Cardiac output...
Question 5
A 35-year-old G3P2 woman presents at 38 weeks gestation for a routine antenatal check-up. Her blood pressure is 120/70 mmHg, and she denies any symptoms. Fundal height measures 34 cm. On abdominal palpation, the fetal head is Ballotable and high above the pelvic brim. An ultrasound reveals an estimated fetal weight of 3.2 kg, amniotic fluid index of 12 cm, and a fundal placenta. The obstetrician is concerned about potential fetal malposition or cephalopelvic disproportion. Which of the following named signs, if present, would strongly suggest fetal head engagement?
A. Leopold's maneuvers.
B. Chadwick's sign.
C. NΓ€gele's rule.
D. Pawlik's grip.
Textbook Explanation Highlight:
The question asks for a named sign that suggests fetal head engagement. Leopold's maneuvers (option 1) are a set of four distinct palpation techniques used to determine fetal lie, presentation, attitude, and position, but they don't refer to a single...
