Which of the following is a sign of approaching death?

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.

Correct Answer: A

Rationale: The correct answer is A because assault is the threat of bodily harm to another person. In this scenario, the nursing assistant is threatening the resident with harm if they disclose information, which constitutes assault. Choice B is incorrect as it describes a resident reporting abuse, which is not an example of assault. Choice C is incorrect as it describes coercion for money, which is more aligned with extortion or theft, not assault. Choice D is incorrect as it describes unprofessional behavior but does not involve a threat of bodily harm, which is necessary for an act to be considered assault.

Correct Answer: A

Rationale: The correct answer is A because mores refer to the accepted traditional customs and norms within a particular group. Mores dictate what is considered morally right or wrong. Choice B is incorrect because emotional well-being levels are not related to mores. Choice C is incorrect as census data does not define mores. Choice D is incorrect because stereotypes are not the same as the customs and traditions that make up mores.

Correct Answer: C

Rationale: The correct answer is C because encouraging the resident to wear his hearing aid is the most appropriate and effective way to help improve his ability to hear. By wearing the hearing aid, the resident can better participate in conversations and activities. Option A is incorrect as it limits the resident's social interactions. Option B is incorrect as raising the pitch of the voice may not necessarily improve the resident's ability to hear. Option D is incorrect as shouting can be perceived as aggressive and is not a respectful way to communicate with someone who has hearing loss.

Correct Answer: D

Rationale: The correct answer is D: Blue-tinged skin and mucous membranes due to a decrease of oxygen in the system. Cyanosis is the bluish discoloration of the skin and mucous membranes caused by inadequate oxygen levels in the blood. This occurs because when blood lacks oxygen, it appears bluer when seen through the skin. The other choices are incorrect because cyanosis is not related to an increase in oxygen (choice A), poisoning (choice B), or bacterial increase in the respiratory system (choice C). The key to understanding the correct answer lies in knowing the physiological basis of cyanosis and its association with oxygen levels in the blood.
