3 Rounds are

Correct Answer: C

Rationale: The correct answer is C because "3 Rounds" refer to a method of reporting where staff members make scheduled visits to each resident's room to assess their needs, monitor their condition, and provide care. This helps ensure that residents receive timely and individualized care. The other choices are incorrect because A refers to the concept of resident assignment, B is about task lists, and D pertains to care plan meetings, which are not specifically related to the term "3 Rounds."

Correct Answer: C

Rationale: Standard Precautions are designed to prevent the transmission of infectious agents in healthcare settings. Choice C is correct as it states that a nursing assistant should use Standard Precautions with every resident in their care, regardless of their known or suspected infectious status. This approach ensures consistent infection control practices and minimizes the risk of spreading infections. Choices A, B, and D are incorrect because Standard Precautions should not be based on self-reporting by residents or their requests; they should be applied universally to all residents to maintain a safe and healthy environment.

Correct Answer: D

Rationale: The correct answer is D: Bend at the knees to lift something. This is the correct way to use proper body mechanics because bending at the knees helps distribute the weight evenly and reduces strain on the lower back. By bending at the knees, you engage the stronger muscles in your legs to lift the object, rather than relying on the weaker muscles in your back. This technique also helps maintain a straight back posture, which is crucial for preventing back injuries. Standing back from an object (A) may lead to overreaching and strain. Keeping feet close together (B) doesn't provide a stable base for lifting heavy objects. Using the muscles of the lower back (C) puts excessive pressure on the back and increases the risk of injury.

Correct Answer: A

Rationale: The correct answer is A because diabetic ketoacidosis occurs when there is an absolute or relative deficiency of insulin in the body. Without enough insulin, the body cannot use glucose for energy, leading to the breakdown of fats and the production of ketones, causing ketoacidosis. Choices B, C, and D are incorrect because having too little insulin (B) leads to diabetic ketoacidosis, not too much insulin. Eating too little food (C) may result in low blood sugar but not diabetic ketoacidosis. Too much exercise (D) can lower blood sugar levels but is not a direct cause of diabetic ketoacidosis.

Correct Answer: C

Rationale: The correct answer is C: Placement of meals. An overbed table is specifically designed to provide a convenient surface for patients to eat their meals while in bed. It helps to ensure a comfortable and accessible dining experience for patients who are unable to sit at a traditional table. Choices A, B, and D are incorrect because an overbed table is not intended for placement of dirty linens, bedpans, or urinals. These items should be placed elsewhere for hygiene and sanitation purposes.
