Final answer:
OPTION C.
The client's understanding of discharge teaching after cataract extraction is shown by their statement about bending at the knees instead of the waist to pick things up, which minimizes pressure on the eye.
Step-by-step explanation:
The correct statement by the client that indicates an understanding of the discharge teaching following a cataract extraction is "I will bend at my knees when picking an object up off the floor." This shows they are aware they should avoid activities that increase intraocular pressure, such as bending over, which could put stress on the eye while it is healing. Resuming daily aspirin therapy could increase the risk of bleeding post-operatively, so it's advisable to consult a doctor before continuing any blood-thinning medication. Itching is a common side effect after surgery and does not always require contacting a provider, but sudden changes like increased redness or vision changes would be concerning. Lifting heavy objects, including a grandchild who weighs 20 pounds, could also increase intraocular pressure and should be avoided.
