Shearing is rubbing or friction that can be prevented by

Correct Answer: D

Rationale: The correct answer is D: A draw sheet. A draw sheet is a protective layer placed between the patient and the bedsheet to reduce friction and shearing forces during movement. It allows for easier repositioning of the patient without causing skin damage. A: A rubber sheet is not typically used for reducing friction or shearing forces in healthcare settings. B: A bottom sheet is the regular bedsheet and does not provide the necessary protection against shearing. C: A top sheet is also a regular bedsheet and does not offer the same benefits as a draw sheet in preventing shearing. In summary, the draw sheet is the most suitable choice as it specifically addresses the issue of shearing and helps protect the patient's skin during movement.

Correct Answer: B

Rationale: The correct answer is B: Chyme. Chyme is a semi-fluid substance produced in the stomach through the breakdown of food by gastric juices. It is then passed into the small intestine for further digestion and absorption. Calculi are solid concretions formed in the body, not related to stomach digestion. Cartilage is a type of connective tissue, and emesis refers to the act of vomiting, not a substance produced in the stomach. Therefore, based on the process of food digestion in the stomach, Chyme is the most appropriate answer.

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.
