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 check on their well-being, address any needs, and ensure proper care. This proactive approach allows for regular monitoring and early intervention if issues arise. A is incorrect as it refers to the assignment of residents to nursing assistants, not the concept of 3 rounds. B is incorrect as it describes a list of tasks to be completed, not the process of making rounds. D is incorrect as it pertains to meetings for care planning, not the routine practice of conducting rounds.

Correct Answer: C

Rationale: The correct answer is C because Standard Precautions should be used with every resident in the nursing assistant's care to prevent the spread of infections, regardless of their perceived health status. This approach ensures consistent protection for both the residents and the nursing assistant. Choices A and B are incorrect as they are based on the residents' statements or suspicions, which may not always be accurate indicators of infectious diseases. Choice D is incorrect because Standard Precautions should be applied universally and not based on individual requests.

Correct Answer: D

Rationale: The correct answer is D because bending at the knees helps maintain a straight back and reduces strain on the lower back. By bending at the knees, the leg muscles are utilized to lift the object instead of relying solely on the lower back. This technique distributes the weight more evenly and decreases the risk of injury. A: Standing back from an object while lifting it may reduce the leverage and make it harder to lift. B: Keeping feet close together when lifting may lead to instability and increase the risk of losing balance. C: Using the muscles of the lower back to lift is incorrect as it can strain the back and cause injury.

Correct Answer: A

Without sufficient insulin, the body breaks down fats for energy, leading to ketone production. 4. Excess insulin can result in hypoglycemia, prompting the body to release stress hormones causing ketoacidosis. Incorrect Choices: B: Having too little insulin in the body - This is the opposite of the correct answer. C: Eating too little food - Insufficient food intake typically leads to hypoglycemia, not ketoacidosis. D: Too much exercise - Intense exercise can increase ketone levels, but alone is not a primary cause of ketoacidosis.

Placement of dirty linens (Choice A) is incorrect as an overbed table is not meant for storing or handling soiled linens. 2. Placement of bedpans (Choice B) is incorrect as overbed tables are not designed for medical waste disposal. 3. Placement of urinals (Choice D) is incorrect as the primary purpose of an overbed table is not for toileting activities.
