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

Answer and Explanation

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 C

Explanation

A. The toe could also be affected by the edema leading to inaccurate reading.
B. Placing the pulse oximeter probe on a skin fold is not recommended. Skin folds can obscure proper positioning of the probe and interfere with accurate readings. Additionally, skin folds may not adequately represent blood flow and oxygenation levels compared to other sites.
C. This location is recommended because it is usually free of the issues that can affect the extremities, such as poor circulation or changes in peripheral perfusion, and can provide a more reliable saturation reading.
D. The finger is the most common site for applying a pulse oximeter probe due to its accessibility and reliability. However, in cases where the fingers are not suitable, such as when there is significant edema or thickened toenails, alternative sites like the toe may be preferred.

A. Celery B. Pears with skin C. Canned pineapple D. Mashed potatoes

Correct Answer is B

Explanation

A. Celery is a low-calorie vegetable that contains some fiber (about 1.6 grams per 100 grams). While it provides some fiber, there are other options with higher fiber content.

B. Pears with their skin are an excellent source of dietary fiber. A medium-sized pear with skin provides about 5.5 grams of fiber. The skin of the pear is particularly rich in insoluble fiber, which aids in digestion and helps prevent constipation.
C. Canned pineapple generally has lower fiber content compared to fresh fruits. Most of the fiber in pineapple comes from the fruit itself, and processing can reduce the fiber content. Therefore, canned pineapple is not as high in fiber compared to other options.
D. Mashed potatoes, especially if they are peeled, are relatively low in fiber. They are primarily a starchy vegetable and do not provide significant amounts of dietary fiber unless consumed with the skin.
