A systemic infection

Correct Answer: A

Rationale: The correct answer is A because a systemic infection affects the whole body, leading to signs and symptoms like fever and chills as the body's immune response is activated. Choice B is incorrect because the symptoms are not confined to the site of infection but are spread throughout the body. Choice C is incorrect as systemic infections involve multiple areas in the body, not just one. Choice D is incorrect as systemic infections can be treated and are not always fatal.

Correct Answer: C

Rationale: The correct answer is C: Incontinent. Incontinence refers to the inability to control bladder or bowel movements. It is a common medical condition that can affect individuals of all ages. It is important to differentiate incontinence from other terms such as indwelling, infectious, and infiltration. Indwelling refers to a catheter or a device that is inserted and remains inside the body. Infectious relates to something caused by or capable of being transmitted by infection. Infiltration refers to the process of seeping or penetrating into a substance or tissue. Therefore, the correct term for being unable to control the bladder or bowels is incontinent.

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: 50%. Staff must report if a resident consumes less than 50% of their meal as it may indicate poor appetite, health issues, or dietary concerns. Reporting at this threshold allows for timely intervention and monitoring. Choice A (75%) is too high and may miss early signs of issues. Choice C (35%) is too low and may not trigger necessary action promptly. Choice D (80%) is above the threshold for reporting, potentially overlooking important concerns.

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.
