The identification of a disease by its signs and symptoms, as well as testing, is called

Correct Answer: D

Rationale: The correct answer is D: Diagnosis. Diagnosis involves identifying a disease through signs, symptoms, and testing. Signs and symptoms help narrow down potential conditions, while testing confirms the diagnosis. Choice A, Differential, refers to the process of distinguishing between two or more conditions with similar symptoms. Choice B, Didactic, relates to teaching methods. Choice C, Disability, pertains to a state of impairment rather than disease identification.

Correct Answer: D

Rationale: The correct answer is D: By listening. Nursing assistants can help residents' families by providing emotional support and understanding their concerns through active listening. By listening attentively, the nursing assistant can offer comfort, gather important information, and establish trust. Talking (choice A) may not always be helpful if it does not involve active listening. Diagnosing (choice B) and treating (choice C) are beyond the scope of a nursing assistant's responsibilities and should be left to healthcare professionals. Listening, on the other hand, is a crucial skill that allows the nursing assistant to provide personalized care and support to the resident's family members.

Correct Answer: A

Rationale: The correct answer is A because actively listening to the resident can help identify the root cause of their anger, allowing for appropriate support and resolution. This approach shows empathy and respect for the resident's feelings. Choice B is incorrect as sharing personal problems with the resident may not be professional and could potentially escalate the situation. Choice C is inappropriate as joking may trivialize the resident's emotions and not address the underlying issue. Choice D is not suitable as the nursing assistant should not encourage the resident to leave the facility without addressing their concerns.

Correct Answer: B

Rationale: The correct answer is B because moving from a dirty area towards a clean area when cleaning surfaces helps prevent cross-contamination. This practice ensures that germs are not spread from contaminated surfaces to clean ones. Choice A is incorrect as holding soiled linens close to the uniform can lead to spreading contaminants. Choice C is incorrect as equipment dropped on the floor should be properly cleaned and disinfected before reuse. Choice D is incorrect as coughing or sneezing into hands can spread germs, and using a tissue or elbow is the recommended practice to prevent infection transmission.

Correct Answer: B

Rationale: The correct answer is B: The victim is breathing. If a person is conscious during a medical emergency, it indicates that they are breathing as consciousness requires oxygen supply to the brain. Lack of pulse (A) would indicate a more serious condition like cardiac arrest. Irregular heartbeat (C) may or may not lead to consciousness. Loss of ability to speak (D) can be due to various reasons unrelated to consciousness. In summary, the ability to breathe is essential for consciousness during a medical emergency.
