Correct Answer: B

Rationale: The correct answer is B: Ectopic pregnancy. In this scenario, the combination of missed periods, positive pregnancy test, and empty uterus on ultrasound with fluid in the cul-de-sac is highly suggestive of an ectopic pregnancy. Ectopic pregnancy occurs when the fertilized egg implants outside the uterus, commonly in the fallopian tube. The presence of fluid in the cul-de-sac indicates possible blood from a ruptured ectopic pregnancy, causing the severe lower abdominal pain. Ovarian cyst rupture (A) typically presents with less severe pain. Septic abortion (C) would present with signs of infection and products of conception in the uterus. Ovarian torsion (D) would present with acute onset of unilateral lower abdominal pain and a palpable adnexal mass, not fluid in the cul-de-sac.

Correct Answer: C

Rationale: The correct answer is C because an open forum to solicit questions related to the topic under discussion is a common practice after a lecture presentation. This allows for clarification and deeper understanding. Choice A is incorrect as evaluation usually comes after the lecture. Choice B is incorrect because the Q&A portion typically focuses on the lecture content only. Choice D is incorrect as cracking humorous anecdotes is not a standard practice after a lecture.

Correct Answer: A

Rationale: The correct answer is A: Loss of self-tolerance. This is because autoimmune diseases result from a breakdown in the immune system's ability to distinguish between self and non-self antigens, leading to the production of antibodies against self-antigens. When self-tolerance is lost, immune cells mistakenly target the body's own tissues, causing tissue damage and inflammation. Choice B (Failure of innate immunity) is incorrect because autoimmune diseases are primarily driven by adaptive immunity rather than innate immunity. Choice C (Defective T cell activation) is incorrect as T cells play a critical role in the immune response to self-antigens in autoimmune diseases. Choice D (Impaired phagocytosis) is incorrect as phagocytosis is a mechanism primarily involved in the removal of pathogens, not in the development of autoimmune diseases.

Correct Answer: C

Rationale: The correct answer is C: Cells die. In Alzheimer's disease, there is a progressive degeneration of brain cells, leading to cell death. This results in a loss of important brain functions such as memory, cognition, and eventually, bodily functions. The atrophy of the brain stem (choice A) is not a characteristic feature of Alzheimer's. Fluid buildup (choice B) is not a primary mechanism of the disease. Tissue swelling (choice D) is not typically associated with the progression of Alzheimer's; rather, there is a gradual loss of brain tissue due to cell death.

Correct Answer: C

Rationale: The correct answer is C because encouraging the patient to ask questions and express concerns promotes patient empowerment and active participation in self-care. This approach fosters communication, understanding, and collaboration between the nurse and patient, leading to better medication adherence. Choice A is incorrect as it lacks patient involvement. Choice B is helpful but does not necessarily empower the patient. Choice D is directive and does not encourage active participation or empowerment.
