Which of the following conditions may cause a resident to become confused?

Correct Answer: B

Rationale: The correct answer is B because taking the wrong medication can lead to confusion due to side effects or interactions. Step 1: Wrong medication can alter brain function. Step 2: Confusion is a common side effect of medication errors. Step 3: Proper oxygenation (A) is unrelated to confusion. Eating dinner (C) and exercising (D) are routine activities that do not directly cause confusion.

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.

Correct Answer: D

Rationale: The correct answer is D: Soy. Soy products are lactose-free and can be used as a substitute for dairy products in individuals who are lactose intolerant. Soy milk, tofu, and soy-based cheeses are good alternatives. Fiber (choice A) and protein (choice C) are not direct substitutes for dairy products. Salt (choice B) is not a suitable substitute for lactose intolerance. Soy is the best choice due to its lactose-free nature and ability to provide similar nutrients as dairy products.
