A client has a new prescription for Timolol eye drops. How should the client prevent systemic absorption of the medication according to the nurse's instructions?

  • A. Bony orbit
  • B. Nasolacrimal duct
  • C. Conjunctival sac
  • D. Outer canthus
Correct Answer: B

Rationale: When the client presses on the nasolacrimal duct while instilling eye drops, it temporarily blocks the lacrimal punctum. This obstruction helps prevent the systemic absorption of the medication by minimizing drainage into the nasolacrimal duct and subsequent systemic circulation. By following this technique, the client can enhance the localized effect of the eye drops and reduce the risk of systemic side effects.
