The lie is defined as unstable when it keeps varying after

Correct Answer: A

Rationale: The correct answer is A (36 weeks gestation) because at this point in pregnancy, the fetus has reached a stable lie position. Before 36 weeks, fetal lie can vary due to the ample space in the uterus. After 36 weeks, the fetus tends to settle into a consistent head-down or breech position, making the lie stable. Choices B, C, and D are incorrect as they are past the point where the lie typically stabilizes, leading to less variability in fetal positioning.

Correct Answer: B

Rationale: The correct answer is B: CT urogram. This is the appropriate next step in the workup for Melanie's microscopic hematuria. A CT urogram can provide detailed imaging of the urinary tract to identify any structural abnormalities or causes of hematuria. A urology consultation (choice A) may be necessary after the imaging results. Upper urinary imaging (choice C) is not specific enough and may not provide a comprehensive evaluation. Cystoscopy (choice D) is invasive and typically reserved for cases where lower urinary tract issues are suspected, which is not indicated in Melanie's case without further evaluation.

Correct Answer: C

Rationale: The correct answer is C: Virilizing tumors in women are most often localized to the adrenal cortex. This is because virilizing tumors typically involve excessive production of androgens, which are male sex hormones, and are commonly associated with adrenal cortex disorders. A is incorrect because feminizing adrenal tumors can be either benign or malignant, not always carcinomas. B is incorrect because feminizing adrenal tumors are rare compared to virilizing tumors. D is incorrect because virilizing adrenal tumors are more likely to be benign rather than malignant in children. In summary, the correct answer highlights the common association of virilizing tumors with the adrenal cortex in women, while the other choices present incorrect information regarding the types and malignancy of adrenal tumors.

Correct Answer: C

Rationale: The correct answer is C: Choanal atresia. The congenital abnormality of the respiratory tract with abnormal apical position is typically associated with choanal atresia, which is a blockage or narrowing of the back of the nasal passage. This condition can lead to respiratory distress in newborns due to difficulty breathing through the nose. Explanation: 1. Laryngeal stridor (Choice A) is a high-pitched noise during breathing and is not typically associated with abnormal apical position. 2. Diaphragmatic hernia (Choice B) is a defect in the diaphragm that allows abdominal organs to move into the chest cavity, but it is not related to abnormal apical position. 3. Tracheo-bronchi fistula (Choice D) is an abnormal connection between the trachea and bronchi, which is not associated with abnormal apical position. In summary, choanal atresia is the correct answer because it fits the description of

Correct Answer: D

Rationale: The correct answer is D. A ruptured uterus can lead to fetal distress and necessitate a cesarean section. Failure of the cervix to dilate is indicative of a potential uterine rupture, as the uterus may not be able to contract effectively due to the rupture. Maternal dehydration (A), pyrexia (B), and oliguria (C) are not specific signs of a ruptured uterus and may be present in various other conditions. Therefore, failure of the cervix to dilate is the most relevant early sign in this scenario.

Correct Answer: D

Rationale: The correct answer is D, complete rupture of the uterus. This is an obstetric emergency due to the risk of severe bleeding and potential harm to both the mother and the fetus. A ruptured uterus can lead to life-threatening complications such as hemorrhage and shock. In contrast, options A, B, and C are not considered obstetric emergencies. Aftercoming head in breech, complete cephalic presentation, and complete breech presentation are normal variations in labor that do not typically require immediate intervention like a ruptured uterus does.

Correct Answer: C

Rationale: The Mauriceau-Smellie-Veit maneuver is the correct answer for delivering the head in a breech presentation. This maneuver involves applying pressure to the fetal head with the fingers in the mouth to flex the head, guiding it through the pelvis. This technique helps prevent hyperextension of the head and facilitates a safe delivery. The Lovset maneuver involves rotating the fetus to disengage the impacted shoulder, not for delivering the head. The Burns Marshall Method is used for delivering the aftercoming head in a breech presentation. The Reverse woodscrew maneuver is a technique to disimpact a shoulder dystocia, not for delivering the head in a breech presentation.

Correct Answer: A

Rationale: Step 1: Sulfadoxine Pyrimethamine is recommended for pregnant women in malaria endemic areas due to its safety and efficacy in preventing malaria during pregnancy. Step 2: Pregnant women are at higher risk of severe complications from malaria, making prophylaxis crucial. Step 3: The World Health Organization recommends intermittent preventive treatment with Sulfadoxine Pyrimethamine for pregnant women in malaria-endemic areas. Step 4: Option A aligns with these guidelines, making it the correct choice. Summary: Option B is incorrect because pregnant women are considered at risk regardless of testing. Option C is incorrect as the timing of administration is not based on quickening. Option D is incorrect as the recommended number of doses may vary based on guidelines.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C is correct: 1. Hyperthermia neonatorum refers to elevated body temperature in newborns. 2. The ed rosy appearance on the face is a common symptom of hyperthermia due to increased blood flow to the skin. 3. Greatly reduced eliminations can be a sign of dehydration associated with hyperthermia. 4. The other choices (hypothermia, hypoglycemia, hypocalcemia) do not align with the symptoms described.
