A nurse is assisting with the development of an education program for a group of older adults. Which of the following actions should the nurse take first?

a.This is not recommended. The central tip of the finger is more sensitive and has more nerve endings, which can cause more pain. The recommended site for blood glucose testing is the side of the fingertip, as it is less sensitive and provides an adequate blood sample.

b. While it is not necessary to wear sterile gloves for routine capillary blood glucose monitoring, it is important to ensure that the nurse's hands are clean. Wearing clean gloves helps maintain infection control practices.

c. After puncturing the selected site, the nurse should gently squeeze the finger to create a small drop of blood. The first drop of blood should be wiped away, and subsequent drops should be used for the glucose test. This ensures that the sample is fresh and not contaminated with tissue fluid.

d.Keeping the finger in a dependent position (hanging down) helps improve blood flow to the fingertip, making it easier to obtain a sufficient blood sample. This can help ensure an accurate glucose reading.

Dry, itchy skin is a common concern in older adults, especially during the winter months or in dry environments. Increasing the humidity in the client's environment can help alleviate dryness and itching. Placing a humidifier in the client's room will add moisture to the air and help prevent excessive drying of the skin. It is important to ensure that the humidifier is clean and well-maintained to avoid the growth of bacteria or mould.

Encouraging the client to bathe frequently may further dry out the skin, so it is not recommended. Similarly, applying powder to the skin may exacerbate dryness and should be avoided. Adding moisturizing oil to the bath water may provide temporary relief, but a humidifier will have a more consistent and long-lasting effect on the client's environment.
