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?
Cataracts.
Diabetic retinopathy.
Glaucoma.
Macular degeneration.
The Correct Answer is A
The correct answer is choice A. Cataracts are a cloudy, opaque area over the lens of one eye that can impair vision
Choice B is wrong because diabetic retinopathy is a condition that affects the blood vessels of the retina, not the lens. It can cause blurred vision, floaters, or vision loss
Choice C is wrong because glaucoma is a condition that damages the optic nerve due to high pressure in the eye. It can cause blind spots, halos around lights, or vision loss
Choice D is wrong because macular degeneration is a condition that damages the macula, the central part of the retina. It can cause blurred or no vision in the center of the visual field

Correct Answer is D
Explanation
Replacing wet clothing with dry clothing is an independent nursing intervention that can help prevent further heat loss and gradually warm the patient. Soaking extremities in hot water (choice A) is not recommended because it can cause vasodilation and hypotension. Administering warmed intravenous fluids (choice B) and administering hot whirlpool therapy (choice C) are not independent nursing interventions because they require a physician’s order. They are also not appropriate for mild to moderate hypothermia because they can cause rapid rewarming and cardiac dysrhythmias.
Correct Answer is A
Explanation
This is because hypokalemia (low potassium level in the blood) can cause abnormal heart rhythms (arrhythmia) that can be life-threatening and require urgent medical attention. A cardiac monitor can help detect and treat any arrhythmia that may occur.
Choice B is wrong because administering a laxative can worsen hypokalemia by causing more potassium loss through the digestive tract. Laxative use is one of the possible causes of hypokalemia.
Choice C is wrong because placing the client on seizure precautions is not a priority intervention for hypokalemia. Seizures are not a common symptom of hypokalemia, although muscle weakness and cramps may occur.
Choice D is wrong because restricting high potassium foods is not a priority intervention for hypokalemia. In fact, increasing potassium intake through foods or supplements may be helpful in less serious cases of hypokalemia. However, this should be done according to the doctor’s recommendation and with careful monitoring of blood potassium levels.
Normal blood potassium levels for an adult range from 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life threatening.
