A 70-year-old patient is diagnosed with cataracts and is discussing treatment options with their healthcare provider. Which of the following is the most appropriate treatment for cataracts?
Prescription glasses to improve vision
Laser therapy to dissolve cataracts
Use of anti-inflammatory eye drops
Cataract surgery to replace the clouded lens with an artificial lens
The Correct Answer is D
Choice A Reason:
Prescription glasses can help improve vision in the early stages of cataracts by compensating for changes in the lens. However, they do not treat the underlying condition. As cataracts progress, glasses become less effective, and surgery becomes necessary to restore clear vision.
Choice B Reason:
Laser therapy is not used to dissolve cataracts. Instead, it is sometimes used after cataract surgery to treat a condition called posterior capsule opacification, which can occur months or years after the initial surgery. This procedure, known as YAG laser capsulotomy, helps to clear the vision but does not address the primary cataract.
Choice C Reason:
Anti-inflammatory eye drops can be used to manage inflammation and discomfort associated with cataracts or cataract surgery. However, they do not treat or remove the cataract itself. These drops are often part of the post-operative care following cataract surgery.
Choice D Reason:
Cataract surgery is the most effective treatment for cataracts. During the procedure, the clouded natural lens is removed and replaced with a clear artificial lens called an intraocular lens (IOL). This surgery significantly improves vision and is considered the definitive treatment for cataracts.

Correct Answer is A
Explanation
Choice A Reason:
Allowing the client to keep her hearing aids in is crucial for effective communication between the nurse and the client. Hearing aids help the client understand instructions and respond appropriately, which is essential for ensuring the client’s safety and comfort before surgery. According to preoperative guidelines, patients with hearing impairments should be allowed to use their hearing aids until they are taken to the operating room. This practice helps reduce anxiety and ensures that the client can hear and understand all preoperative instructions and consent information.
Choice B Reason:
Allowing the client to consume clear liquids up to the time of surgery is generally not recommended. Preoperative fasting guidelines typically require patients to stop consuming clear liquids at least two hours before surgery to reduce the risk of aspiration during anesthesia. Therefore, this option is not appropriate for ensuring the client’s safety.
Choice C Reason:
Allowing the client to take her morning vitamins is not advisable without specific instructions from the surgical team. Some vitamins and supplements can interact with anesthesia or increase the risk of bleeding during surgery. It is essential to follow the surgical team’s guidelines regarding medication and supplement intake before surgery.
Choice D Reason:
Allowing the client to keep her tongue stud in is not recommended. All jewelry and body piercings should be removed before surgery to prevent complications such as electrical burns during the use of electrocautery devices or interference with airway management. Removing the tongue stud is necessary to ensure the client’s safety during the procedure.
Correct Answer is A
Explanation
Choice A Reason:
Storing hearing aids in a dry, cool place when not in use is crucial for maintaining their functionality and longevity. Moisture and heat can damage the delicate electronic components of hearing aids. Using a dehumidifier specifically designed for hearing aids can help prevent moisture buildup and extend the life of the devices.
Choice B Reason:
Using cotton swabs to clean the interior components of the hearing aid is not recommended. Cotton swabs can push debris further into the hearing aid and potentially damage the internal components. Instead, specialized cleaning tools such as wax loops, brushes, and earmold tubing blowers should be used to clean hearing aids properly.
Choice C Reason:
It is not okay to wear hearing aids while showering or swimming. Most hearing aids are water-resistant but not waterproof. Exposure to water can damage the hearing aids and affect their performance. It is important to remove hearing aids before any activities involving water.
Choice D Reason:
Replacing the batteries of hearing aids once a month regardless of usage is not necessary. Battery life depends on the type of hearing aid, the battery size, and the amount of usage. It is more practical to replace the batteries when they are low or depleted, as indicated by the hearing aid’s low battery warning.
