A nurse is preparing to administer timolol eye drops for a client who has glaucoma. When instilling the medication, which of the following actions should the nurse take?

Instruct the client to blink several times after instillation of the medication.

Ask the client to look straight ahead during instillation of the medication.

Apply pressure to the bridge of the nose after instillation of the medication.

Place each drop of the medication directly on to the client's cornea.

Answer and Explanation

The Correct Answer is C

Choice A reason: This is an incorrect action, because instructing the client to blink several times after instillation of the medication can cause the medication to drain out of the eye and reduce its effectiveness.

Choice B reason: This is a correct action, but not the best one. Asking the client to look straight ahead during instillation of the medication can help the nurse to aim the drop accurately and avoid touching the eye with the dropper.

Choice C reason: This is the best action, because applying pressure to the bridge of the nose after instillation of the medication can prevent the medication from entering the systemic circulation and causing adverse effects, such as bradycardia, hypotension, or bronchospasm.

Choice D reason: This is an incorrect action, because placing each drop of the medication directly on to the client's cornea can cause irritation, injury, or infection to the eye. The medication should be placed in the lower conjunctival sac of the eye.

Correct Answer is D

Explanation

Choice A reason: This is an incorrect action, because emptying the drainage container every 4 hr is not necessary and can interfere with the accurate measurement of the drainage volume. The drainage container should be emptied only when it is full or at the end of the shift.

Choice B reason: This is an incorrect action, because changing the client's insertion-site dressing each shift can increase the risk of infection and dislodgment of the chest tube. The insertion-site dressing should be changed only when it is soiled or loose.

Choice C reason: This is an incorrect action, because clamping the chest tube when the client is ambulating can cause a tension pneumothorax, which is a life-threatening complication of chest tube insertion. The chest tube should be clamped only when ordered by the provider or when changing the drainage system.

Choice D reason: This is the correct action, because placing the drainage unit below the client's chest level can facilitate the drainage of air and fluid from the pleural space by gravity. The drainage unit should be kept below the client's chest level at all times.

A. Weigh the client before and after each dialysis treatment. B. Apply clean gloves when handling the bags of dialysate fluid. C. Refrigerate the bags of dialysate fluid until ready for instillation. D. Check peripheral circulation of the client's arms prior to treatment.

Correct Answer is A

Explanation

Choice A reason: This is the correct action, because weighing the client before and after each dialysis treatment can help monitor the fluid balance and the effectiveness of the dialysis.

Choice B reason: This is an incorrect action, because the nurse should apply sterile gloves when handling the bags of dialysate fluid to prevent infection.

Choice C reason: This is an incorrect action, because the bags of dialysate fluid should be warmed to body temperature before instillation to prevent hypothermia and abdominal cramps.

Choice D reason: This is an irrelevant action, because checking peripheral circulation of the client's arms has no relation to peritoneal dialysis, which involves the insertion of a catheter into the abdominal cavity.
