Which of the following is an example of objective information?

Correct Answer: A

Rationale: The correct answer is A because "A resident's face is drooping on one side" is a factual observation that can be objectively verified. This statement describes a physical appearance that can be seen and assessed without interpretation or bias. In contrast, choices B, C, and D involve subjective opinions, emotions, or preferences that cannot be independently verified. Choice B reflects a resident's personal feeling, choice C reflects a subjective experience, and choice D reflects a personal decision. Therefore, they are not considered objective information.

Correct Answer: B

Rationale: The correct answer is B because a mask must completely cover the nursing assistant's nose and mouth to effectively protect against the transmission of infectious agents. This ensures that respiratory droplets are filtered out. Choice A is incorrect because the mask should be removed after gloves and gown to prevent contamination. Choice C is incorrect as changing the mask every 30 minutes is not necessary unless it becomes visibly soiled or damaged. Choice D is incorrect as masks should not be reused due to the risk of contamination.

Correct Answer: D

Rationale: The correct answer is D: Epistaxis. "Epistaxis" is the medical term for nosebleed. "Epi-" means above or upon, and "staxis" refers to dripping or oozing. Therefore, "epistaxis" specifically refers to bleeding from the nose. A: Epidermis refers to the outermost layer of skin, not related to nosebleeds. B: Epiglottis is the flap of tissue that covers the trachea during swallowing, not related to nosebleeds. C: Emesis refers to vomiting, not related to nosebleeds. In summary, the correct answer is D because it is the term specifically used to describe bleeding from the nose, while the other choices are unrelated terms in the context of nosebleeds.

Correct Answer: C

Rationale: The correct answer is C: At least every two hours. Repositioning residents in wheelchairs every two hours helps prevent pressure ulcers and discomfort. Repositioning every 15 minutes (A) may not be necessary unless prescribed by a healthcare provider for specific cases. Every hour (B) may be too frequent for some residents, leading to unnecessary disruptions. Repositioning every five minutes (D) is too frequent and can be impractical and disruptive. Regular repositioning promotes circulation and prevents skin breakdown without causing unnecessary discomfort.

Correct Answer: A

Rationale: The correct answer is A: On the arm inside the elbow. The brachial pulse is found on the arm, specifically inside the elbow, where the brachial artery runs close to the surface. This location allows for easy palpation and accurate assessment of the pulse rate. Choices B, C, and D are incorrect because the brachial pulse is not located on the wrist (B), left side of the chest (C), or right side of the chest (D). Palpating the brachial pulse in the elbow area is crucial for assessing blood flow and circulation in the upper extremities.
