A nurse is preparing to lift a box of supplies in the supply room. Which of the following body mechanics should the nurse plan to use?
Standing with his feet close together when lifting
Keeping the box close to his body as he lifts it
Bending at the waist to pick up the box
Twisting to place the box to his side
The Correct Answer is B
A. Standing with feet close together reduces the base of support, making the nurse less stable and increasing the risk of losing balance or straining muscles. It is not recommended for lifting because it compromises stability and balance.
B. Keeping the box close to the body reduces the leverage and strain on the back muscles. This technique utilizes the strength of the legs and core muscles more effectively and helps to maintain balance and stability while lifting.
C. Bending at the waist puts excessive strain on the lower back muscles and can lead to back injury, especially when lifting heavy objects. The correct technique is to bend at the knees and hips while keeping the back straight to maintain proper alignment and reduce strain on the spine.
D. Twisting while lifting or carrying heavy objects can strain the muscles and ligaments of the spine, leading to injury, particularly to the intervertebral discs. The nurse should avoid twisting and instead pivot the entire body with the feet to change direction.

Correct Answer is ["100"]
Explanation
For this scenario, the volume to be infused is 100 mL, the drop factor is 60 gtt/mL, and the time is 60 minutes.
Plugging in the numbers: (100 mL × 60 gtt/mL) / 60 min = 6000 gtt / 60 min = 100 gtt/min.
Therefore, the nurse should set the IV flow rate to deliver 100 drops per minute.
Correct Answer is C
Explanation
A. Apples are a good source of fiber, with about 4.4 grams of fiber in a medium-sized apple with the skin. Apples contain soluble and insoluble fiber, which can aid in digestion and help prevent constipation. This is a suitable choice for a high-fiber snack.
B. Almonds are nutritious and provide fiber, but they are not as high in fiber compared to other options like fruits, vegetables, and whole grains. One ounce of almonds contains about 3.5 grams of fiber. While almonds are beneficial, they are not typically the primary choice for increasing fiber intake to alleviate constipation.
C. Bran cereals are often recommended for their high fiber content. Half a cup of bran cereal can provide around 10 grams of fiber or more, depending on the brand and type. Bran cereals are particularly rich in insoluble fiber, which adds bulk to stool and helps promote regular bowel movements. This is an excellent choice for increasing fiber intake to manage constipation.
D. Sweet potatoes are nutritious and contain dietary fiber, with about 3.8 grams of fiber in half a cup of cooked sweet potatoes. While they contribute to fiber intake, they generally do not provide as much fiber compared to options like whole grains or bran cereals.
