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, including breath sounds. Lung sounds can provide important information about a person's 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. Urine flow is assessed through other methods like urinalysis, body temperature is measured using a thermometer, and blood pressure is measured using a sphygmomanometer.

Correct Answer: A

Rationale: The correct answer is A: Caffeinated beverages. Caffeine is a diuretic that increases urine production by inhibiting the reabsorption of water in the kidneys. This leads to more urine being produced. Warm milk (B) and yogurt (C) do not have diuretic properties. High-sodium fluids (D) may actually decrease urine production as the body retains more water to balance the sodium levels.

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, moist cloth or pack to a specific area of the body to reduce swelling and inflammation. This method constricts blood vessels, numbs the area, and slows down nerve conduction, providing pain relief and promoting healing. Summary of why other choices are incorrect: B: Aquamatic K-pad - This is not a dry application as it involves the use of water. C: Sponge bath - This is a form of moist application as it involves using a sponge soaked in water. D: Warm soak - This is also a moist application as it involves soaking a body part in warm water.

Correct Answer: D

Rationale: The correct answer is D: Nasal cannula. A resident using an oxygen concentrator needs a nasal cannula to deliver the concentrated oxygen directly to their nostrils for breathing. The nasal cannula is essential for effective oxygen therapy and ensures the resident receives the prescribed amount of oxygen. A: Portable oxygen tank is not necessary when using an oxygen concentrator as it generates oxygen continuously. B: Irrigation catheter is not relevant to oxygen therapy and serves a different medical purpose. C: Specimen container is used for collecting samples and has no connection to oxygen therapy. In summary, the nasal cannula is crucial for delivering oxygen, while the other choices are not related to oxygen therapy.

Correct Answer: A

Rationale: The correct answer is A: Expressive. Expressive aphasia, also known as Broca's aphasia, is characterized by difficulty in speech production and writing. This is due to damage in the brain's language centers affecting the ability to convey thoughts and ideas. Choice B, Cognitive, is incorrect as it refers to general mental processes, not specifically communication. Choice C, Validating, is unrelated to aphasia and communication difficulties. Choice D, Receptive, is also incorrect as it refers to difficulty in understanding language rather than expressing it.
