Correct Answer: D

Rationale: The correct answer is D: Splenectomy. In this case, the patient presents with signs of immune thrombocytopenic purpura (ITP) with low platelet count and bleeding time prolongation. Splenectomy is the definitive treatment for ITP as the spleen is the site of platelet destruction. Avoiding elective surgery and medications (choice A) may be necessary to prevent bleeding complications but do not address the underlying issue. Prednisone (choice B) is used for acute treatment but not for long-term management. Monoclonal antibody therapy (choice C) is an option for refractory cases but not first-line therapy.

Correct Answer: B

Rationale: The correct answer is B because reduced facial movement is a key clinical feature of facial palsy. This can lead to difficulty in making facial expressions, closing the eye on the affected side, and drooping of the mouth. Irritability may also occur due to discomfort or difficulty in communication. Choice A is incorrect because inability to feed and excessive cry are not typical features of facial palsy. Choice C is incorrect as excessively dry eyeball and feeding difficulties are not commonly associated with facial palsy. Choice D is incorrect as eyes being permanently open and no facial movement are not characteristic of facial palsy.

Correct Answer: D

Rationale: The correct answer is D: Breast cancer. The patient's breast cancer is the reason she is ineligible to donate organs. Breast cancer is a contraindication for organ donation due to the risk of cancer transmission to the recipient. Traumatic brain injury (choice B) and renal failure (choice A) are not absolute contraindications to organ donation. Gram-negative infection (choice C) may temporarily disqualify the patient but can be treated, unlike breast cancer. In summary, breast cancer poses the highest risk of organ recipient harm compared to the other medical conditions listed.

Correct Answer: B

Rationale: The correct answer is B: Emergency cesarean section. Emergency cesarean sections can increase the risk of puerperal sepsis due to the urgency of the procedure, which may lead to inadequate sterilization or contamination. Other choices are less directly associated with puerperal sepsis: A may increase the risk of infection, but not specifically puerperal sepsis. C relates to general hygiene practices and D focuses on delays in seeking care, which may affect treatment outcomes but are not direct predisposing factors to puerperal sepsis.

Correct Answer: A

Rationale: The correct answer is A: Respiratory insufficiency. Chronic traumatic diaphragmatic hernias can lead to gradual compromise of respiratory function due to herniation of abdominal contents into the chest cavity, causing compression of the lungs and reduced lung capacity. This results in symptoms such as dyspnea, cough, and chest pain. Sepsis (B) is more commonly associated with acute traumatic diaphragmatic hernias. Bowel obstruction (C) is a possible complication but typically presents with acute symptoms like abdominal pain and distension. Anemia (D) is not a common presentation of diaphragmatic hernias.
