The advantage of a dental bridge is

Correct Answer: B

Rationale: The correct answer is B because a dental bridge is specifically designed to replace missing teeth, restoring functionality and aesthetics. It helps maintain proper alignment, chewing ability, and speech. Choice A is incorrect as gloves are still necessary for infection control. Choice C is incorrect because dental bridges can crack under certain circumstances. Choice D is incorrect as dental bridges can and should be cleaned regularly for oral hygiene.

Correct Answer: B

Rationale: The correct answer is B: Difficulty chewing and swallowing. As people age, muscle strength and coordination in the mouth and throat may decline, leading to challenges in chewing and swallowing. This can result in issues such as choking and aspiration. This change is a normal part of aging due to weakening muscles. Choices A, C, and D are incorrect as they do not directly relate to age-related changes in the gastrointestinal system. Taste sensitivity may decrease with age, saliva production can decrease, and the movement of waste through the intestines may slow down rather than speed up.

Correct Answer: D

Rationale: The correct answer is D: Endometrial cancer. This form of cancer starts in the lining of the uterus, called the endometrium. Cervical cancer (A) originates in the cervix, ovarian cancer (B) in the ovaries, and testicular cancer (C) in the testicles. By process of elimination, endometrial cancer is the only choice that correctly matches the description of cancer beginning in the uterus.

Correct Answer: B

Rationale: The correct answer is B: Increasing iron intake. Iron is essential for the production of hemoglobin, which carries oxygen in red blood cells. Anemia is often due to an iron deficiency, so increasing iron intake helps replenish iron stores and improve red blood cell production. Reducing vitamin intake (A) is not recommended as vitamins play a crucial role in overall health. Injections of vitamin K (C) are not typically used to treat anemia. Decreasing fiber in the diet (D) is unrelated to anemia and can even worsen the condition by limiting nutrient absorption.

Rationale: The correct answer is B: Pad the edge of the cast to reduce sharp edges. This is important to prevent skin irritation and injury from the rough edges of the cast. By padding the edges, it helps to distribute pressure evenly and decrease the risk of abrasions. Choice A is incorrect because using a sharp scratcher inside the cast can lead to skin damage and infections. Choice C is incorrect as keeping the cast damp or wet can cause skin maceration and increase the risk of infection. Choice D is incorrect as keeping the extremity low close to the ground can lead to swelling and discomfort.
