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.

Correct Answer is A
Explanation
A. Instruct the client to flex their head in a chin-down position: Flexing the head forward helps close the airway and direct food toward the esophagus, reducing the risk of aspiration. This maneuver is a standard safety technique for clients with dysphagia during swallowing.
B. Place the food on the weaker side of the client's mouth: Food should be placed on the stronger side of the mouth to facilitate effective chewing and swallowing. Placing food on the weaker side increases the risk of aspiration and choking.
C. Thin the food to a liquid consistency prior to feeding: Thinner liquids are more difficult for clients with dysphagia to control and swallow safely. Thickened liquids are recommended to slow flow and improve swallow safety.
D. Place the client in a semi-Fowler's position while eating: While upright positioning is important, semi-Fowler’s (30–45 degrees) may not be sufficient. A full upright position (90 degrees) is preferred to optimize swallowing and reduce aspiration risk.
Correct Answer is ["1.5"]
Explanation
Calculation:
- Identify the ordered dose and available concentration
Ordered Dose: 30 mg
Available Concentration: 100 mg/5 mL
- Calculate the volume to administer
Volume to administer = (Ordered Dose ÷ Concentration) × Volume of Concentration
Volume to administer = (30 ÷ 100) × 5
Volume to administer = 0.3 × 5
Volume to administer = 1.5 mL
