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: B

Rationale: The correct answer is B: Inadequate surfactant levels. Surfactant is a substance that reduces surface tension in the alveoli, preventing their collapse. In respiratory distress syndrome, premature infants have insufficient surfactant production, leading to collapsed alveoli and difficulty breathing. Choice A is incorrect because it focuses on quality rather than quantity of surfactant. Choice C is incorrect as rib cage underdevelopment is associated with congenital conditions like thoracic dystrophy, not RDS. Choice D is incorrect as gradual alveolar rupture is not a known cause of RDS.

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.

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: D

Rationale: The use of bed cradle in leg thrombosis management is to promote venous drainage. Elevating the legs on a bed cradle helps improve blood flow back to the heart, reducing swelling and preventing blood clots. Keeping the legs straight (A) is not the main purpose. Preventing embolism (B) is important but not the direct purpose of a bed cradle. Controlling body temperature (C) is unrelated to the use of a bed cradle for leg thrombosis.
