One way to use proper body mechanics on the job is to

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: 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.

Correct Answer: A

Rationale: The correct answer is A: Partial bath. For an elderly person with very dry skin, a partial bath is appropriate as it helps to prevent further drying of the skin by focusing on areas that need cleaning, while minimizing exposure to water which can exacerbate dryness. Other choices such as a shower or tub bath involve prolonged exposure to water and may strip the skin of its natural oils, worsening dryness. A complete bed bath is not necessary for someone with dry skin and can be physically taxing for the elderly individual.

Correct Answer: C

Rationale: The correct answer is C: Axilla. The axilla is the anatomical term for the armpit region. The axilla contains lymph nodes, blood vessels, and nerves that supply the upper limb. The other choices are incorrect: A tympanum refers to the eardrum, B rectum is part of the digestive system, and D temporal pertains to the side of the head.

Correct Answer: A

Rationale: Step-by-step rationale: 1. MyPlate recommends choosing low-fat or fat-free dairy for better health. 2. 1% fat dairy is lower in saturated fat compared to 2%, 3%, or 4% fat options. 3. Lower fat content aligns with dietary guidelines for reducing saturated fat intake. 4. Choosing 1% fat dairy helps in maintaining a healthy weight and heart health. Summary: A is correct as it aligns with MyPlate's recommendation for low-fat dairy. B, C, and D are incorrect as they contain higher fat content, which may contribute to higher saturated fat intake and potential health risks.
