A nurse is teaching a client who has glaucoma and a new prescription for timolol eyedrops. Which of the following statements by the client indicates an understanding of the teaching?
"I should expect my tears to turn a red color after using the eye drops."
"I will put pressure on the corner of my eye after using the eye drops."
"The drops should be placed in the center of my eye."
"These drops will improve my cloudy vision."
The Correct Answer is B
A. "I should expect my tears to turn a red color after using the eye drops.": Timolol does not cause red discoloration of tears. Redness of the eye may indicate irritation, allergy, or another adverse effect, so the client should report persistent redness rather than expect it as normal.
B. "I will put pressure on the corner of my eye after using the eye drops.": Applying gentle pressure to the nasolacrimal duct (inner corner of the eye) after instilling timolol reduces systemic absorption and potential systemic side effects, such as bradycardia or hypotension. This technique demonstrates proper administration and understanding of safety precautions.
C. "The drops should be placed in the center of my eye.": Eye drops should be instilled into the lower conjunctival sac, not directly onto the center of the cornea, to reduce irritation and maximize absorption. Placing drops on the cornea can cause discomfort and reduce effectiveness.
D. "These drops will improve my cloudy vision.": Timolol lowers intraocular pressure but does not restore vision or improve cloudiness caused by glaucoma. The goal of therapy is to prevent progression of vision loss, not to reverse existing damage.

Explanation
Calculation:
- Identify the ordered dose and available concentration
Ordered Dose: 50 mcg
Available Concentration: 100 mcg/2 mL
- Calculate the volume to administer
Volume to administer = (Ordered Dose ÷ Concentration) × Volume of Concentration
Volume to administer = (50 ÷ 100) × 2
Volume to administer = 0.5 × 2
Volume to administer = 1 mL
Correct Answer is ["A","B","D"]
Explanation
A. Wear a lead apron when providing care: Lead aprons help protect the nurse from radiation exposure when providing close care to a client with a sealed radiation implant. This is a standard safety precaution in managing patients receiving internal radiation therapy.
B. Close the door to the client's room: Keeping the door closed limits unnecessary exposure to radiation for other clients and staff in the unit. It also helps maintain a controlled environment for infection and radiation safety.
C. Place the client in a semi-private room: Clients with sealed radiation implants should be placed in a private room to minimize radiation exposure to other patients and staff. Semi-private rooms increase the risk of unnecessary exposure and are not recommended.
D.This is an application of Time. The risk of radiation damage is cumulative. By restricting visits to 30 minutes per 24-hour period, the facility ensures that guests stay well below the threshold for accidental radiation injury.
E.This is incorrect for two reasons. First, pregnant women and children under the age of 18 are generally prohibited from visiting a client with a radiation implant due to the high sensitivity of developing fetal and juvenile tissues. Second, even for authorized visitors, the safe distance is at least 6 feet (2 meters), not 3 feet.
