Correct Answer: B

Rationale: The correct answer is B: Compatible blood and tissue types. This is crucial to minimize the risk of rejection and ensure a successful transplant. Matching blood and tissue types help prevent the recipient's immune system from attacking the new organ. Blood relationship (A) is not as important as compatibility. Sex and size (C) are important considerations for certain transplants but not the most crucial factor. Need (D) is relevant but does not outweigh the importance of compatibility to ensure a successful transplant.

Correct Answer: C

Rationale: The correct answer is C: Bleeding gums and dark tarry stools. Thrombocytes are platelets responsible for blood clotting. Medications that depress thrombocytes can lead to decreased clotting ability, resulting in bleeding tendencies. Bleeding gums and dark tarry stools are common signs of bleeding due to decreased platelet function. A: Sore throat and swollen glands are more indicative of a possible infection or inflammation, not related to thrombocyte depression. B: Pernicious anemia with weakness is associated with vitamin B12 deficiency, not directly related to thrombocyte depression. D: Thickening of blood and bruising are not typical signs of decreased platelet function, but rather may be indicative of other conditions like clotting disorders.

Correct Answer: C

Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons or target cells. It is coated with a myelin sheath, which helps speed up the transmission of impulses. Dendrites (A) receive signals from other neurons, the neurolemma (B) is the outermost layer of the myelin sheath, and the synapse (D) is the junction between two neurons where neurotransmitters are released. Therefore, the axon is the only part of the neuron specifically responsible for transmitting impulses away from the cell body.

Correct Answer: B

Rationale: The correct answer is B: ELISA and Western Blot. The rationale is as follows: ELISA (enzyme-linked immunosorbent assay) and Western Blot are specific tests used to confirm HIV infection by detecting antibodies or antigens related to the virus. ELISA is the initial screening test, while Western Blot is the confirmatory test. These tests are highly sensitive and specific for HIV detection. Choice A is incorrect because CD4+ cell count and thymus function are not tests used to confirm HIV infection. They are used to monitor disease progression and immune function in HIV-positive individuals. Choice C is incorrect because B-cell and T-cell count are also not tests used to confirm HIV infection. They are indicators of immune system health but not specific for HIV diagnosis. Choice D is incorrect because while CD4+ and viral load tests are used in monitoring HIV progression, ELISA is the main confirmatory test for HIV diagnosis, and viral load is not typically used for initial

Correct Answer: B

Rationale: The correct answer is B: Nausea and vomiting. Chemotherapeutic drugs commonly cause nausea and vomiting due to their effect on the gastrointestinal system. This is because these drugs can irritate the stomach lining and trigger the vomiting center in the brain. Nausea and vomiting are well-documented side effects of chemotherapy and are often managed with antiemetic medications. A: Painful mouth sores are a common side effect of some chemotherapeutic drugs, but they are not the most common adverse effect. C: Frequent diarrhea can occur as a side effect of chemotherapy, but it is less common than nausea and vomiting. D: Constipation is not a common adverse effect of chemotherapeutic drugs; in fact, diarrhea is more commonly seen.
