Correct Answer: D

Rationale: The correct answer is 'Upper arm circumference.' Upper arm circumference is a better indicator of total muscle mass in adolescents compared to height, weight, or triceps skinfold thickness. Triceps skinfold thickness primarily reflects subcutaneous fat, while weight and height are not specific to muscle mass. Upper arm circumference directly measures the muscle mass in the upper arm and can provide a more accurate assessment in this context. Therefore, choices A, B, and C are incorrect because they do not directly reflect total muscle mass in adolescents.

Correct Answer: B

Rationale: The correct answer is to ensure the client is sitting upright while eating. This position helps prevent aspiration and facilitates swallowing. Offering tart or sour foods (Choice A) may not be suitable for someone with dysphagia as they can be difficult to swallow and may increase the risk of aspiration. Providing soft and easily swallowable foods (Choice C) is crucial for individuals with swallowing difficulties. While giving thickened liquids (Choice D) is a common intervention for dysphagia, the priority during mealtime should be ensuring the client's proper positioning to support safe swallowing and prevent aspiration.

Correct Answer: B

Rationale: The correct answer is B. The documentation should be clear and precise, providing details about the context of the fall. Choice A is vague and does not specify the cause of the client being on the floor. Choice C is less specific and does not directly state that the client fell from the bed. Choice D is wordy and less direct compared to option B, which clearly states that the client fell out of bed and was found on the floor.

Correct Answer: A

Rationale: The correct answer is to flush the tube before and after each medication administration. This helps prevent clogging and ensures the medication is delivered properly. Mixing medications with enteral feeding (choice B) is incorrect as medications should be administered separately. Pushing tablets through the tube (choice C) is not recommended as they should be properly dissolved before administration. Mixing all crushed medications before dissolving them in water (choice D) is incorrect; medications should be dissolved individually to avoid interactions or inconsistencies in dosages.

Correct Answer: B

Rationale: The correct answer is B. Petroleum jelly is flammable and should not be used with oxygen therapy due to the risk of fire. The client should avoid using petroleum-based products around oxygen equipment. Choices A, C, and D are all appropriate statements for a client with COPD receiving home oxygen therapy. Keeping the oxygen tank upright ensures proper oxygen flow, avoiding smoking or exposure to smoke helps prevent respiratory aggravation, and knowing to seek medical help promptly for breathing difficulties is essential for managing COPD effectively.
