A nurse is teaching a client who requires maximal support about how to use a two-wheeled walker. Which of the following actions by the client indicates an understanding of teaching?

The nurse should ask a second nurse to record her signature when wasting any unused portion of the controlled substance. This is a standard procedure for the safe handling and documentation of controlled substances.

a. The nurse should report any discrepancy in the count total of the controlled substance before administration, not after.

b. The wasted portion of the controlled substance should be disposed of according to facility policy, which may not involve placing it in a sharps container.

c. The count total of the controlled substance should be verified before removing the amount needed, not after.

The development of erythema (redness) along the path of the vein indicates phlebitis at the IV site. Phlebitis refers to inflammation of the vein, often caused by irritation or infection. When phlebitis occurs, the vein becomes inflamed and can appear red, warm, and tender to touch. Erythema is a characteristic sign of phlebitis and suggests that the client's IV site has become irritated or infected.

Let's now discuss why the other

Options are not the correct answers:

1. Coolness of the client's left forearm: Coolness of the forearm is not typically associated with phlebitis. Instead, it may suggest compromised blood flow to the area, such as arterial insufficiency, rather than inflammation of the vein.
2. Pallor of the client's left forearm: Pallor, or paleness, of the forearm is not a typical finding in phlebitis. It usually indicates reduced blood flow or decreased oxygenation to the area, which can be caused by factors other than inflammation of the vein.
3. Pitting edema at the insertion site: Pitting edema refers to the indentation that remains when pressure is applied to an area of swelling and then release. While edema can occur at the insertion site of an IV, it is not a specific indicator of phlebitis. Edema can result from multiple causes, such as fluid overload or localized inflammation, and its presence does not necessarily confirm the presence of phlebitis.

In summary, the presence of erythema along the path of the vein is the finding that indicates the development of phlebitis at the IV site. This redness suggests inflammation of the vein, which can be caused by various factors including irritation or infection. The other

Options, such as coolness of the forearm, pallor of the forearm, or pitting edema at the insertion site, are not specific indicators of phlebitis and may be associated with different underlying conditions or factors.
