A nurse is preparing to administer an ophthalmic medication to a client. Which of the following actions should the nurse plan take?

A) Apply pressure to the client's nasolacrimal duct after instillation:
Applying gentle pressure to the nasolacrimal duct (located at the inner corner of the eye) after administering ophthalmic medication helps to reduce systemic absorption and increase the medication’s efficacy. This technique helps to prevent the medication from draining into the nasolacrimal duct and into the systemic circulation.

B) Clean the client's eye from the outer canthus to the inner canthus before instillation:
The eye should be cleaned from the inner canthus to the outer canthus to avoid transferring debris or infection from the outer parts of the eye to the inner areas. Cleaning from outer to inner canthus may cause contamination.

C) Ask the client to tightly squeeze their eyes shut after the instillation:
Asking the client to tightly squeeze their eyes shut is not recommended as it can cause the medication to be expelled or lead to increased systemic absorption. Instead, the client should gently close their eyes to allow for proper absorption.

D) Instill the ophthalmic medication directly on the client's cornea:
The medication should be administered into the conjunctival sac rather than directly on the cornea. Direct application to the cornea can cause irritation or damage.

A) Muscle pain:
Verapamil is a calcium channel blocker used to treat cardiac dysrhythmias and hypertension. Muscle pain is not a common adverse effect associated with verapamil. Instead, side effects related to cardiovascular function are more pertinent.

B) Ototoxicity:
Ototoxicity, which refers to hearing damage or tinnitus, is not a known side effect of verapamil. This is more commonly associated with certain antibiotics or chemotherapy agents, not calcium channel blockers like verapamil.

C) Hypotension:
Hypotension is a significant concern with verapamil, as it can lower blood pressure due to its vasodilatory effects. Monitoring blood pressure is crucial when administering verapamil, especially during an IV bolus, to ensure it does not drop too low and lead to symptoms of dizziness or fainting.

D) Hyperthermia:
Hyperthermia, or elevated body temperature, is not typically associated with verapamil use. Verapamil's side effects are more focused on cardiovascular and gastrointestinal systems, rather than temperature regulation.
