The most common cause of immediate postpartum haemorrhage is uterine atony, not trauma to the genital tract.

Correct Answer: A

Rationale: The correct answer is A: TRUE. Uterine atony is the most common cause of immediate postpartum hemorrhage due to inadequate uterine contraction to control bleeding. This is supported by research and clinical evidence. Trauma to the genital tract is a less common cause and usually leads to delayed hemorrhage. Choice B is incorrect as uterine atony is a well-documented primary cause. Choice C is incorrect as uterine atony is consistently the leading cause. Choice D is incorrect as the cause of immediate postpartum hemorrhage is clear, with uterine atony being the most common culprit.

Correct Answer: D

Rationale: The correct answer is D: Aspiration and culture of fluid. Given Jasmine's history of injection drug use, neck pain, inability to turn her neck, elevated temperature, and foul breath, there is a high suspicion of a deep neck space infection. Aspiration and culture of fluid from the affected area will help identify the causative organism and guide appropriate antibiotic therapy. This procedure is essential for definitive diagnosis and management of deep neck infections. A: Anteroposterior neck radiography is not the most appropriate initial diagnostic test for evaluating deep neck space infections as it may not provide detailed information on the extent or nature of the infection. B: CT scan of the neck may provide valuable information regarding the extent of the infection, but aspiration and culture of fluid are crucial for identifying the causative organism. C: White blood cell (WBC) differential may show signs of inflammation, but it does not provide specific information on the causative organism of the infection.

Correct Answer: A

Rationale: The correct answer is A (36 weeks gestation) because at this stage, the fetal lie should stabilize into a consistent position, typically longitudinal. Before 36 weeks, fetal movement and position can vary frequently. Choices B, C, and D are incorrect as they are past the point where fetal lie should have stabilized. At 42 weeks gestation (Choice B), the baby is considered post-term, and fetal lie should have already been established. Similarly, Choices C (38 weeks) and D (40 weeks) fall within the expected range for fetal lie stabilization.

Correct Answer: D

Rationale: The correct answer is D, as all three choices are key indicators for cesarean section during labor. Fetal distress indicates the baby is not tolerating labor well. Failure to progress may lead to complications for the mother or baby. Breech presentation increases the risk of complications during vaginal delivery. Therefore, all three indicators warrant consideration for a cesarean section to ensure the safety of both the mother and the baby.

Correct Answer: A

Rationale: The correct answer is A because high-volume liver resection is typically performed in individuals with significantly compromised hepatic function to ensure adequate liver remnant. Removing 50 to 75% of the liver in a patient with metastatic colon cancer may be necessary for tumor clearance but carries risks due to potential impairment of liver function postoperatively. Choices B and C provide inaccurate information regarding the timeline and extent of liver regeneration following resection. Choice D is incorrect as removing up to 95% of the liver would lead to severe consequences, such as liver failure. Hence, option A is the most appropriate advice given the patient's situation.

Correct Answer: A

Rationale: The correct answer is A: HELLP syndrome. This must be evaluated as a cause of abdominal pain in a pregnant patient because it is a serious condition characterized by hemolysis, elevated liver enzymes, and low platelet count. These abnormalities can lead to abdominal pain, especially in the right upper quadrant. Placental abruption (B) presents with vaginal bleeding and uterine tenderness, not specific abdominal pain. Spontaneous hepatic rupture (C) is rare and usually presents with sudden severe abdominal pain. Preterm labor (D) typically presents with regular uterine contractions and lower abdominal discomfort, not specific upper quadrant pain like in HELLP syndrome.

Correct Answer: A

Rationale: The correct answer is A: Temperature > 102°F. A high fever in the context of right lower quadrant colicky pain raises concern for ureteral colic, which is often caused by kidney stones. Fever may indicate infection or obstruction, requiring urgent medical attention. Choices B, C, and D are incorrect because they are common findings in cases of ureteral colic but are not as specific to raise the index of suspicion. White blood cell count elevation and hematuria are common with kidney stones, while vomiting is a common symptom due to severe pain. However, fever is a more concerning sign that necessitates prompt evaluation.

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: B

Rationale: The correct answer is B: Lipoma. A lipoma is a common benign tumor made of fat cells. In this case, the patient's presentation of a painless, soft, round, flesh-colored lump with smooth borders is consistent with a lipoma. The absence of symptoms like pain, erythema, or tenderness further supports this diagnosis. Lipomas are usually non-tender to palpation and can grow to a significant size. The other choices (A, C, D) are not the correct answers because they do not align with the characteristics described in the patient's presentation. Neurolemma is associated with nerve sheath tumors, hemangioma with blood vessel tumors, and lymphangioma with lymphatic vessel tumors, none of which match the clinical findings in this case.
