A stethoscope may be used to hear

Correct Answer: A

Rationale: The correct answer is A: Air in the lungs. A stethoscope is used to listen to sounds produced by the body, such as heartbeats and lung sounds. By placing the stethoscope on the chest, one can hear the air moving in and out of the lungs during breathing. This is important for assessing respiratory health. Choices B, C, and D are incorrect because a stethoscope is not used to listen to urine flow, body temperature, or blood pressure.

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.

Correct Answer: A

Rationale: The correct answer is A: Expressive. Expressive aphasia, also known as Broca's aphasia, is characterized by difficulty in producing speech or writing. This is due to damage in the brain's language centers affecting the ability to communicate verbally. Choice B, Cognitive, is incorrect as it pertains to general mental processes rather than specifically communication difficulties. Choice C, Validating, is unrelated to aphasia and refers to confirming or verifying something. Choice D, Receptive, is also incorrect as it refers to difficulty understanding spoken or written language, not difficulty expressing oneself verbally or in writing.
