Correct Answer: C

Rationale: The correct answer is C: Human, T-cell lymphotrophic virus, as it is the causative agent for HIV/AIDS. This virus specifically targets and infects the body's T-cells, weakening the immune system. Trichomonas vaginalis, Treponema pallidum, and Chlamydia trachomatis are all different pathogens that do not cause HIV/AIDS. Trichomonas vaginalis is a protozoan parasite that causes trichomoniasis, Treponema pallidum causes syphilis, and Chlamydia trachomatis causes chlamydia. Therefore, the correct answer is C based on the specific viral agent responsible for HIV/AIDS.

Correct Answer: D

Rationale: The correct answer is D: Aphasia. Aphasia is a language disorder that affects a person's ability to communicate and understand speech. In this case, Mr. Dela Isla's difficulty in comprehending what the nurse was saying indicates a problem with language processing, which aligns with the symptoms of aphasia. Insomnia (A) is a sleep disorder, not related to language comprehension. Agnosia (B) is a perception disorder where someone cannot recognize objects or people, not related to language. Apraxia (C) is a motor disorder affecting the ability to perform purposeful movements, not related to language comprehension.

Correct Answer: A

Rationale: The correct answer is A because signs and symptoms listed are indicative of disseminated intravascular coagulation (DIC), which is a serious condition where blood clotting and bleeding occur simultaneously. Change in level of consciousness can indicate hypoperfusion from clotting in blood vessels. Tachypnea and tachycardia can result from tissue hypoxia. Petechiae are small red or purple spots on the skin due to bleeding under the skin. Choices B, C, and D are incorrect because they do not align with the typical signs and symptoms of DIC. Choice B suggests a possible myocardial infarction or acute coronary syndrome. Choice C indicates a possible thrombotic thrombocytopenic purpura (TTP) or acute limb ischemia. Choice D suggests a mix of symptoms that do not typically present together in DIC.

Correct Answer: C

Rationale: The correct initial treatment for stage IV ovarian cancer is major surgery (Choice C). This is because at this advanced stage, surgery is typically performed to debulk the tumor and remove as much cancerous tissue as possible, followed by chemotherapy to target any remaining cancer cells. Radiation therapy (Choice A) is not typically the initial treatment for ovarian cancer. Chemotherapy (Choice B) is often used in combination with surgery, but surgery is usually the first line of treatment for stage IV disease. Choosing no treatment (Choice D) would be detrimental as the cancer is advanced and requires immediate intervention.

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. Levothyroxine is a synthetic form of thyroid hormone used to treat hypothyroidism. If the dose is too high, it can lead to symptoms of hyperthyroidism, including tachycardia (rapid heartbeat). This is because an excess of thyroid hormone can increase the heart rate. Dysuria (choice A) is not a common adverse effect of levothyroxine. Leg cramps (choice C) are more commonly associated with electrolyte imbalances. Blurred vision (choice D) is not a typical adverse effect of levothyroxine.
