Shearing is rubbing or friction that can be prevented by

Correct Answer: D

Rationale: Sure! The correct answer is D: A draw sheet. A draw sheet is a thin, protective sheet placed under a patient to reduce friction and shearing forces when moving them in bed. It prevents skin damage and discomfort. A rubber sheet (A) is not specifically designed for reducing shearing forces. A bottom sheet (B) and a top sheet (C) are regular bed linens and do not provide the same level of protection against shearing as a draw sheet. The draw sheet is the most appropriate choice for preventing shearing in this context.

Correct Answer: B

Rationale: The correct answer is B: Chyme. Chyme is a semi-fluid substance formed from the breakdown of food in the stomach. It consists of partially digested food mixed with gastric juices. Calculi are stones formed in the body, not a product of food breakdown. Cartilage is a type of connective tissue, not a stomach product. Emesis refers to vomiting, which is the expulsion of stomach contents, not a product of food breakdown. Thus, chyme is the only choice that accurately describes a substance resulting from the breakdown of food in the stomach.

Correct Answer: A

Rationale: The correct answer is A: Caffeinated beverages. Caffeine is a diuretic that increases urine production by promoting the excretion of water from the body. When consumed, caffeine inhibits the reabsorption of water in the kidneys, leading to increased urine output. Choices B, C, and D do not have diuretic properties like caffeine and therefore do not directly increase urine production. Warm milk, yogurt, and high-sodium fluids may affect hydration status but do not have the same direct impact on urine production as caffeine.

Correct Answer: A

Rationale: The correct answer is A: Cold compress. A cold compress is a type of dry application that involves applying a cold, damp cloth to a specific area of the body to reduce swelling and inflammation. This method constricts blood vessels, numbs the area, and provides pain relief. Why the other choices are incorrect: B: Aquamatic K-pad - This choice is incorrect because it involves a moist heat application using a heating pad, not a dry application. C: Sponge bath - This choice is incorrect as it involves using water to cleanse the body, which is a wet application, not dry. D: Warm soak - This choice is incorrect because it involves immersing the body or body part in warm water, which is a wet application, not dry.

Correct Answer: D

Rationale: The correct answer is D: Nasal cannula. A resident using an oxygen concentrator needs a nasal cannula to deliver the oxygen from the concentrator to their lungs effectively. The nasal cannula is a lightweight, flexible tube that is placed in the nostrils to provide a continuous flow of oxygen. It ensures proper oxygen delivery and improves the resident's breathing. A portable oxygen tank (Choice A) is not necessary when using an oxygen concentrator, as the concentrator generates oxygen continuously. An irrigation catheter (Choice B) and a specimen container (Choice C) are not relevant to oxygen therapy and are not needed for a resident using an oxygen concentrator.
