A nurse is caring for a client who has a cloudy, opaque area over the lens of one eye.
The nurse should identify that this is a manifestation of which of the following visual impairments?

Choice A is correct because maintaining a regular sleep routine can help regulate your circadian rhythm, which is your body’s natural sleep-wake cycle. This can improve the quality and quantity of your sleep and reduce daytime sleepiness.

Choice B is wrong because eating three large meals a day can cause fluctuations in your blood sugar levels, which can affect your energy levels. It is better to eat smaller, more frequent meals and snacks that contain a balance of protein and carbohydrates to keep your blood sugar stable and provide sustained energy. Choice C is correct because limiting refined sugar, fried foods and processed foods can help prevent fatigue by reducing inflammation and oxidative stress in your body.

These foods can also cause spikes and crashes in your blood sugar levels, which can make you feel tired and hungry. Instead, you should eat more anti-inflammatory foods, such as fruits, vegetables, nuts, seeds and fish.

Choice D is correct because taking daily walks can help prevent fatigue by increasing your blood circulation, oxygen delivery and endorphin production. Exercise can also improve your mood, sleep quality and immune system.

Choice E is wrong because increasing caffeine intake can have the opposite effect of preventing fatigue.

Caffeine is a stimulant that can temporarily boost your energy levels, but it can also disrupt your sleep, cause dehydration, increase anxiety and lead to withdrawal symptoms

This is an example of secondary prevention, which is the action taken to stop the progress of the disease at the initial stage and prevent complications. An echocardiogram can help diagnose the severity and cause of heart failure and guide the treatment plan.

A client who has a family history of breast cancer and is scheduled for a mammogram is an example of secondary prevention. Secondary prevention is early detection of a disease before it progresses. Secondary prevention can include screenings and other forms of diagnostic tests.

This is an example of tertiary prevention, which is the action taken to stop the progress of the disease at the initial stage and prevent complication. An echocardiogram can help diagnose the severity and cause of heart failure and guide the treatment plan.

Choice C is wrong because it is not an example of any level of prevention.

A client who is asymptomatic is not scheduled for a series of tests because there is no indication of any disease or risk factor.

Choice D is wrong because it is an example of primary prevention, which is the action taken to prevent the development of disease.

A client who is scheduled to receive an influenza vaccination is protected from getting infected by the virus and developing flu-related complications.
