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

Splenomegaly and jaundice are signs of hemolytic anemia, a disorder in which red blood cells are destroyed faster than they are made.

Splenomegaly is an enlargement of the spleen, which may trap and destroy healthy red blood cells. Jaundice is a yellowing of the skin and eyes caused by the buildup of bilirubin, a waste product of hemoglobin breakdown. Choice A is wrong because red, sore tongue is a sign of vitamin B12 deficiency anemia, not hemolytic anemia.

Choice B is wrong because pica is a craving for nonfood items, such as ice, dirt, or starch. It is a sign of iron deficiency anemia, not hemolytic anemia. Choice D is wrong because paresthesias are sensations of tingling, numbness, or prickling in the hands or feet. They are a sign of pernicious anemia, a type of vitamin B12 deficiency anemia, not hemolytic anemia.
