What is the membrane that covers and protects the lungs?

Correct Answer: D

Rationale: The correct answer is D: Pleur. The pleura is the double-layered membrane that covers and protects the lungs. The visceral pleura is in direct contact with the lung tissue, while the parietal pleura lines the chest cavity. This protective membrane helps reduce friction during breathing. Plaque (A), Pancreas (B), and Lymph (C) are incorrect choices. Plaque is a buildup of fatty deposits in arteries, not related to the lungs. The pancreas is an organ involved in digestion and hormone regulation, not part of the lung structure. Lymph refers to the fluid and the system that helps the body fight infections, not a membrane covering the lungs.

Correct Answer: D

Rationale: Immunotherapy is the correct answer because it uses antibodies or vaccines to boost the body's immune system to target and destroy cancer cells. It specifically targets malignant tumors without harming normal cells. Radiation therapy (A) uses high-energy rays to kill cancer cells, hormone therapy (B) blocks hormones that cancer cells need to grow, and chemotherapy (C) uses drugs to kill rapidly dividing cells, including cancer cells. However, only immunotherapy directly harnesses the immune system to fight cancer cells.

Correct Answer: D

Rationale: The correct answer is D (6). Performing range of motion exercises at least 6 times for each joint helps maintain joint flexibility and prevent stiffness. This number strikes a balance between providing sufficient stimulation for improvement and avoiding overexertion. Choice A (9) may be excessive and could lead to fatigue or strain. Choices B (5) and C (3) may not provide enough repetitions to effectively improve joint mobility. Therefore, option D is the most appropriate for promoting optimal joint health.

Correct Answer: C

Rationale: The correct answer is C, Terminal illness. Terminal illness refers to a condition that will ultimately lead to death. This term is specifically used to describe an illness with no possibility of a cure or recovery. Marginal illness (A) refers to a minor or insignificant health issue. Palliative illness (B) refers to a condition in which the goal is to provide relief from symptoms but not necessarily cure it. Complicated illness (D) refers to a condition that is complex in nature but does not imply a fatal outcome. Therefore, Terminal illness is the most appropriate term to describe an illness that will inevitably result in death.

Correct Answer: B

Rationale: Ablative surgery involves removal of diseased tissue, such as amputating a gangrenous foot, to eliminate the pathology.
