A systemic infection

Correct Answer: A

Rationale: The correct answer is A because a systemic infection affects the entire body, leading to signs and symptoms like fever and chills. This is due to the spread of the infection through the bloodstream, causing a systemic immune response. Choices B and C are incorrect as they suggest localized infections, not systemic. Choice D is incorrect as not all systemic infections are fatal; the outcome depends on various factors such as the type of pathogen and the individual's immune response.

Correct Answer: C

Rationale: The correct answer is C: Incontinent. Incontinence refers to the inability to control bladder or bowel movements. It is a medical condition that can occur due to various factors such as muscle weakness, nerve damage, or medical conditions. The term "indwelling" refers to a catheter or medical device that remains inside the body. "Infectious" relates to the spread of diseases caused by pathogens. "Infiltration" typically refers to the diffusion of substances into tissues. In this context, incontinence is the most appropriate term to describe the inability to control bladder or bowel functions.

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 (50%). Staff must report if a resident consumes less than 50% of his meal as this indicates a significant decrease in food intake which could impact the resident's health. Reporting at 75% (Choice A) may be too lenient and miss early signs of decreased appetite. Reporting at 35% (Choice C) may be too strict and result in unnecessary reporting for minor fluctuations. Reporting at 80% (Choice D) may not capture instances where the resident is not consuming enough food for proper nutrition. Therefore, 50% is the most appropriate threshold for reporting.

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.
