Question

question 10 (2 points) saved which statement is true regarding rheumatoid arthritis and osteoarthritis? rheumatoid arthritis is an autoimmune disease. osteoarthritis is mainly treated with methotrexate. osteoarthritis is less common than rheumatoid arthritis. rheumatoid arthritis affects mainly the proximal interphalangeal and distal interphalangeal joints. question 11 (2 points) saved why does the registered nurse instruct the parents of a young girl to reduce the use of sunblock and cover - ups with their child? overuse of sunblock and cover - ups will inhibit the production of estrogen. absorption of calcium by the gastrointestinal tract is inhibited by the overuse of sunblock and cover - ups. the production of osteoblast cells is inhibited by the excessive use of sunblock and cover - ups. the level of parathyroid hormone decreases with the excessive use of sunblock and cover - ups. question 12 (2 points) saved which type of melanoma is characterized by deep, penetrative growth and early metastasis? superficial spreading melanoma lentigo maligna melanoma acral lentiginous melanoma nodular melanoma

Explanation:

1. Question 10: Rheumatoid arthritis is an autoimmune disease where the immune system attacks the joints. Methotrexate is mainly used for rheumatoid arthritis, not osteoarthritis. Osteoarthritis is more common than rheumatoid arthritis. Rheumatoid arthritis often affects multiple joints symmetrically, not just proximal and distal interphalangeal joints.
2. Question 11: Sunlight exposure is needed for the skin to synthesize vitamin D, which helps in calcium absorption in the gastrointestinal tract. Over - use of sunblock and cover - ups reduces sunlight exposure and thus inhibits calcium absorption.
3. Question 12: Nodular melanoma is characterized by deep, penetrative growth and early metastasis. Superficial spreading melanoma is the most common type and grows horizontally first. Lentigo maligna melanoma is slow - growing on sun - damaged skin. Acral lentiginous melanoma occurs on palms, soles, etc.

Answer:

Question 10: Rheumatoid arthritis is an autoimmune disease.
Question 11: Absorption of calcium by the gastrointestinal tract is inhibited by the overuse of sunblock and cover - ups.
Question 12: Nodular melanoma
