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 potential side effects or drug interactions. This can affect cognitive function. A resident receiving proper oxygen (A) is necessary for overall health but unlikely to directly cause confusion. Eating dinner (C) and exercising (D) are healthy activities that are less likely to cause confusion compared to medication errors.

Correct Answer: D

Rationale: Certainly! The correct answer is D: Epistaxis. "Epi-" means "upon" or "above," and "staxis" means "dripping." Epistaxis specifically refers to bleeding from the nose. A: Epidermis is the outer layer of the skin. B: Epiglottis is a flap of cartilage that covers the windpipe during swallowing. C: Emesis refers to vomiting. Therefore, D is the correct answer as it directly relates to the medical term for nosebleed.

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 promotes circulation. Repositioning every 15 minutes (A) or every five minutes (D) is too frequent and can disrupt residents' comfort and activities. Repositioning every hour (B) may not provide adequate relief from prolonged pressure. Hence, repositioning every two hours strikes a balance between prevention and resident wellbeing.

Correct Answer: A

Rationale: The correct answer is A because the brachial pulse is located on the arm inside the elbow, specifically the inner aspect of the upper arm. This pulse is commonly used for blood pressure measurements and is one of the major pulse points in the body. Choices B, C, and D are incorrect as the brachial pulse is not located inside the wrist, on the left side of the chest, or on the right side of the chest. It's important to know the precise location of the brachial pulse for accurate assessment and monitoring of cardiovascular health.

Correct Answer: D

Rationale: The correct answer is D: Soy. Soy can be used as a substitute for dairy products in individuals who are lactose intolerant. Soy milk, tofu, and other soy-based products are good sources of protein and can be easily digested by those with lactose intolerance. Soy is a suitable alternative as it does not contain lactose, unlike dairy products. A: Fiber is not a suitable substitute for dairy products for someone who is lactose intolerant as it does not provide the necessary nutrients found in dairy. B: Salt is not a substitute for dairy products and does not provide the essential nutrients needed in the diet. C: Protein is a good nutrient to include in the diet, but solely relying on protein as a substitute for dairy may not be adequate for individuals who are lactose intolerant.
