__________ is a sexually-transmitted infection that includes symptoms such as itching swollen testesor vaginal bleeding.

Correct Answer: D

Rationale: The correct answer is D: Trichomoniasis. This STI is caused by a parasite called Trichomonas vaginalis, not a bacteria like gonorrhea (A) or chlamydia (C). Symptoms include itching and swollen genitals, not vaginal bleeding like in cases of vaginitis (B). Trichomoniasis is commonly associated with these specific symptoms, making it the most appropriate choice.

Correct Answer: B

Rationale: The correct answer is B: Bursae. Bursae are small sacs filled with synovial fluid near joints that help reduce friction between bones, tendons, and muscles. Tendonitis (A) is inflammation of a tendon, not fluid-filled sacs. Sepsis (C) is a severe infection in the bloodstream, unrelated to joint structures. Phlebitis (D) is inflammation of a vein, not associated with joint fluid sacs. Therefore, Bursae is the only choice that accurately describes the tiny sacs of fluid near joints.

Correct Answer: C

Rationale: The correct answer is C: Hemianopsia. Hemianopsia refers to the loss of vision in half of the visual field, typically caused by damage to the brain's visual pathways. Hyperopia (A) and Myopia (B) are refractive errors affecting visual acuity, not visual field loss. Macular degeneration (D) is a condition affecting central vision, not half of the visual field. Hemianopsia specifically describes the loss of vision in one-half of the visual field due to neurological issues or brain damage.

Correct Answer: C

Rationale: The correct answer is C: Nonspecific. At birth, infants possess nonspecific immunity, also known as innate immunity. This type of immunity provides immediate defense against a wide range of pathogens without prior exposure. It includes physical barriers like skin, chemical barriers like stomach acid, and cellular defenses like macrophages. This innate immunity is essential for protecting newborns from infections until their adaptive immune system develops. Explanation of other choices: A: Active immunity is acquired through exposure to antigens and the subsequent production of antibodies by the individual's own immune system. It is not present at birth. B: Passive immunity is acquired through the transfer of pre-formed antibodies from another individual, such as through breast milk or placental transfer. It is not present at birth. D: Specific immunity, also known as adaptive immunity, is developed over time through exposure to specific antigens and the production of memory cells. It is not present at birth.

Correct Answer: C

Rationale: The correct answer is C: Sepsis. Sepsis is a serious illness caused by the body's response to an infection, often bacterial. It can lead to tissue damage, organ failure, and death if not treated promptly. Gingivitis is a gum disease, Phlebitis is inflammation of a vein, and Diverticulosis is the presence of small pouches in the colon. These conditions are not directly related to bacterial infections causing a serious illness like sepsis.
