A 78-year-old client with arthritis in the left knee is utilizing a cane. The nurse has determined that the client is using the cane properly when

The client adjusts the cane to keep the arm at 90 degrees.

The client adjusts the cane 3 inches below the axilla.

The client steps forward with their left leg with the cane on the left side of their body.

The client steps forward with their left leg while using the cane on the right side of the body.

Answer and Explanation

The Correct Answer is D

A. The client adjusts the cane to keep the arm at 90 degrees: A 90° elbow angle is too flexed for proper cane height; the handle should allow about 20–30° of elbow flexion (wrist crease level) for good posture and leverage.

B. The client adjusts the cane 3 inches below the axilla: Positioning the cane relative to the axilla is not correct-cane height should be set to the wrist crease with the client standing; a placement 3 inches below the axilla suggests incorrect measurement and may cause poor gait mechanics.

C. The client steps forward with their left leg with the cane on the left side of their body: When the cane is held on the same side as the affected (weaker) leg, it provides less effective support; the cane is most beneficial when placed on the side opposite the affected leg.

D. The client steps forward with their left leg while using the cane on the right side of the body: Holding the cane on the stronger (right) side and advancing the cane together with the weaker (left) leg increases stability and offloads the affected limb, which reflects appropriate cane technique.

Correct Answer is ["B","D","E"]

Explanation

A. Recap the needle after giving an injection: Avoid recapping needles because it increases the risk of accidental needlestick injuries; safe practice is to dispose of the needle/syringe immediately without recapping.

B. Use needleless devices whenever possible: Utilizing needleless systems and safety-engineered devices reduces the number of opportunities for percutaneous injury and is a recommended prevention strategy.

C. Remove needle and dispose in sharps box: After completing the procedure, the entire needle/syringe assembly should be placed directly into a puncture-resistant, clearly marked sharps container without recapping or removing the needle from the syringe.

D. Never force needles into the sharps disposal: Do not force items into the sharps container -forcing can lead to accidental puncture or spills; use an appropriate-sized container that is accessible and not overfilled.

E. Use clearly marked sharps disposal containers: Clearly labeled, puncture-resistant sharps containers placed at point of use are essential for safe, timely disposal and to minimize handling.

A. "First draw up the NPH insulin; then draw up the regular insulin in the same syringe." B. "First draw up and administer the regular insulin, then draw up and administer the NPH insulin." C. "First draw up and administer the NPH insulin. Wait at least 15 minutes; then draw up and administer the regular insulin." D. "First draw up the regular insulin; then draw up the NPH insulin in the same syringe."

Correct Answer is D

Explanation

A. "First draw up the NPH insulin; then draw up the regular insulin in the same syringe.": Drawing the cloudy NPH first then the clear regular risks contaminating the regular insulin vial with NPH; this order increases the chance of altering the short-acting vial.

B. "First draw up and administer the regular insulin, then draw up and administer the NPH insulin.": Giving two separate injections (regular first, then NPH) would avoid mixing errors, but it increases number of injections; when mixing in one syringe, the usual safe procedure is still to draw the clear (regular) before the cloudy (NPH).

C. "First draw up and administer the NPH insulin. Wait at least 15 minutes; then draw up and administer the regular insulin.": Separating administration with a wait is unnecessary and may delay glucose control; also drawing NPH first still risks contaminating the regular vial if mixing is later attempted.

D. "First draw up the regular insulin; then draw up the NPH insulin in the same syringe.": When mixing regular (clear) and NPH (cloudy) in one syringe the standard technique is clear before cloudy -draw the regular insulin first, then the NPH -to avoid contaminating the short-acting vial and ensure accurate dosing.
