The home health care nurse discards outdated and leftover medications from previous prescriptions at the home of an elderly client. which quality and safety education for nurses (qsen) competency does this intervention involve?

There are 6 definitions that are recognized in the QSEN  project and each of them are very important for the proper care and protection of the patients.

In your question the correct answer is SAFETY.

Explanation:

In the SAFETY aspect of QSEN the nurse need to minimize or better said eliminate the potential hazards while caring for the patient. Here the nurse is affected by accountability because is his/her responsibility to make sure that nothing pose a threat to the patient. Many times the relatives are not aware of the danger that a medicine that has expired will have on his beloved one but a nurse should always be aware of such a thing and never let a patient take medicine that has expired.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
