Nonsterile dressings are applied to

Correct Answer: C

Rationale: The correct answer is C because nonsterile dressings are suitable for dry wounds with low infection risk, as they do not introduce additional bacteria. Open wounds (A) and draining wounds (B) require sterile dressings to prevent infection. New wounds (D) may benefit from sterile dressings to minimize the risk of introducing bacteria during the initial healing phase.

Correct Answer: C

Rationale: The correct answer is C: Preventing falls. This is because individuals with multiple sclerosis often experience mobility issues and are at a higher risk of falling. By implementing fall prevention strategies, such as removing trip hazards and providing assistive devices, caregivers can help ensure the safety of the resident. Rushing residents through tasks (A) is not recommended as it can increase stress and anxiety, which may exacerbate symptoms of multiple sclerosis. Administering medications (B) is important but not specific to caring for someone with multiple sclerosis. Encouraging the resident to speak faster (D) is not relevant to the care of individuals with multiple sclerosis and may even be detrimental to effective communication.

Correct Answer: D

Rationale: The correct answer is D: Maintains blood sugar levels. The endocrine system produces hormones that regulate blood sugar levels. Insulin and glucagon help control glucose levels in the blood. A: Regulating body temperature is primarily controlled by the nervous system and thermoregulatory mechanisms. B: Giving the body shape and structure is mostly the role of the skeletal system. C: Sensing and interpreting messages from the environment is mainly the function of the nervous system.

Correct Answer: C

Rationale: The correct answer is C: To provide stability when a person is unsteady or has some weakness. A cane is used to support individuals who have difficulty with balance or weakness in their legs. It helps distribute weight and provide stability while walking. Choice A is incorrect because while a cane can help with balance, it is not its primary purpose. Choice B is incorrect as it refers to a different assistive device like a walker. Choice D is incorrect because a cane is used for walking assistance, not for getting out of bed.

Correct Answer: A

Rationale: Step 1: Low blood pressure is a common sign of approaching death due to the body's decreased ability to maintain normal blood flow. Step 2: As organs fail, blood pressure drops, leading to decreased perfusion and oxygen delivery. Step 3: This can result in cold, clammy skin, confusion, and decreased consciousness as the body shuts down. Step 4: Sharper vision (B), being warm (C), and having dry skin (D) are not specific signs of approaching death and do not directly relate to the body's physiological changes in the same way low blood pressure does. Summary: Low blood pressure is a significant indicator of approaching death due to its direct impact on organ perfusion and oxygen delivery, unlike the other choices which lack this direct physiological connection.
