Which of the following is a reason that people are at greater risk for infection as they get older?

Correct Answer: B

Rationale: Step 1: As people age, their immune systems weaken, making them more susceptible to infections. Step 2: A stronger immune system helps fight off pathogens and infections effectively. Step 3: Elderly people being hospitalized more often is a consequence of weakened immunity, not a reason. Step 4: Older people recovering quickly from illness does not relate to the risk of infection.

Correct Answer: A

Rationale: Certainly! The correct answer is A because during a suspected heart attack, it's crucial to keep the resident NPO (nothing by mouth) to avoid exacerbating the situation. Providing food or fluids can potentially worsen the condition by increasing the workload on the heart. Choices B and C are incorrect as covering with a heavy blanket or promoting standing can lead to overheating and increased strain on the heart. Choice D is also incorrect as leaving the resident unattended to call family delays necessary medical intervention.

Correct Answer: D

Rationale: The correct answer is D: Increased irritability. Lack of sleep disrupts mood regulation and can lead to increased irritability due to heightened emotional reactivity and decreased tolerance for stressors. This is supported by research showing that sleep deprivation negatively impacts emotional regulation. The other choices are incorrect because lack of sleep actually causes decreased mental function, slower reaction time, and weakened immune system function.

Correct Answer: C

Rationale: The correct answer is C because being ambulatory means the ability to walk. Thus, a resident who is ambulatory can get out of bed and walk. This is a basic functional ability associated with ambulation. Choices A, B, and D are incorrect as they do not directly relate to the concept of ambulatory status. Feeding oneself, remembering who and where one is, and speaking clearly are important skills but not specifically tied to ambulation.

Correct Answer: A

Rationale: The correct answer is A: Muscle aches. Fever often causes muscle aches due to the body's inflammatory response to infection. This is a common symptom as elevated body temperature can lead to muscle discomfort. Sleepiness (B) is a possible symptom but not as specific to fever. Slow movements (C) are not directly caused by fever. Nausea (D) can be a symptom of fever, but muscle aches are more commonly associated with it.
