The advantage of a dental bridge is

Correct Answer: B

Rationale: The correct answer is B: It replaces missing teeth. A dental bridge is a prosthetic device used to fill the gap created by one or more missing teeth. By bridging the gap, it helps restore proper chewing and speaking functions, prevents shifting of surrounding teeth, and improves the overall appearance of the smile. The other choices are incorrect because: A is incorrect as gloves are still necessary for handling dental bridges due to hygiene reasons; C is incorrect as dental bridges can crack over time depending on the material used and maintenance; and D is incorrect as dental bridges can and should be cleaned regularly to maintain oral health.

Correct Answer: B

Rationale: The correct answer is B: Difficulty chewing and swallowing. As people age, the muscles in the mouth and throat may weaken, leading to challenges with chewing and swallowing. This can result in slower eating and increased risk of choking. Incorrect options: A: Increase in the ability to taste - This is not a normal age-related change. Taste buds may decrease with age, leading to a reduced ability to taste. C: Increase of saliva production - Saliva production typically decreases with age, not increases. D: More rapid movement of body waste through the intestines - Aging usually slows down the movement of waste through the intestines, leading to constipation rather than rapid movement.

Correct Answer: D

Rationale: The correct answer is D: Endometrial cancer. The endometrium is the inner lining of the uterus, so cancer that originates there is termed endometrial cancer. Cervical cancer (A) starts in the cervix, not the uterus. Ovarian cancer (B) originates in the ovaries, not the uterus. Testicular cancer (C) affects the testicles, not the uterus. Thus, the correct answer is D as it aligns with the site of origin for uterine cancer.

Correct Answer: B

Rationale: The correct answer is B: Increasing iron intake. Iron is essential for the production of red blood cells, which carry oxygen in the blood. Anemia is often caused by a lack of iron, leading to a decrease in red blood cell production. Increasing iron intake through diet or supplements can help replenish iron stores and improve red blood cell count. Choice A is incorrect because reducing vitamin intake would not address the underlying cause of anemia. Choice C is incorrect as vitamin K is not typically used to treat anemia. Choice D is incorrect as fiber does not directly impact iron absorption or red blood cell production. Overall, increasing iron intake is the most effective treatment for anemia.

Correct Answer: B

Rationale: The correct answer is B because padding the edge of the cast helps reduce sharp edges, preventing skin irritation and potential injury. It ensures the patient's comfort and safety. Choice A is incorrect as scratching inside the cast can cause skin damage and infection. Choice C is incorrect as keeping the cast damp or wet can lead to skin breakdown and infection. Choice D is incorrect as keeping the extremity low close to the ground can increase swelling and discomfort.
