NCLEX-PN Nursing — All Questions

An LPN/VN is reinforcing education with a client starting warfarin. Which statement indicates correct understanding?

• a.I will stop eating all green vegetables from now on
• b.I will double the dose if I forget one on a given day
• c.I will keep my intake of green vegetables about the same✓
• d.I will take an aspirin daily for my aching knee joints

Consistency of vitamin K intake, rather than avoidance, keeps the anticoagulant effect stable. Eliminating greens, doubling a missed dose, and adding daily aspirin all destabilize the therapy or increase bleeding.

An LPN/VN is giving a client eye drops in the right eye. Where should the drop be placed?

• a.In the lower conjunctival sac of the eye✓
• b.At the inner corner near the tear duct
• c.Under the upper lid with the eye closed
• d.Directly onto the center of the cornea

The lower conjunctival sac holds the drop and spreads it across the eye without touching sensitive tissue. Dropping on the cornea causes pain and blinking, the inner corner drains the drop away, and the upper lid is not accessible for instillation.
