A person is experiencing stress because they are worried about passing their driver's license test tomorrow. This is an example of what type of stress?

Choice A reason: Cataracts are a condition that causes the lens of the eye to become cloudy and opaque. They can cause symptoms such as blurred vision, glare, halos, and reduced color perception. They do not affect the shape of the lines on the Amsler grid or the center of vision.

Choice B reason: Glaucoma is a condition that causes increased pressure in the eye and damage to the optic nerve. It can cause symptoms such as gradual loss of peripheral vision, tunnel vision, and eye pain. It does not affect the shape of the lines on the Amsler grid or the center of vision.

Choice C reason: Macular degeneration is a condition that affects the macula, the central part of the retina. It can cause symptoms such as distorted vision, dark spots, and loss of central vision. It can affect the shape of the lines on the Amsler grid and the center of vision.

Choice D reason: Retinal detachment is a condition that occurs when the retina separates from the back of the eye. It can cause symptoms such as flashes, floaters, and a curtain-like vision loss. It does not affect the shape of the lines on the Amsler grid or the center of vision.

Choice A reason: This is the correct answer because stopping the KCl infusion is the first and most urgent action that the nurse should take. A high level of potassium in the blood, or hyperkalemia, can cause life-threatening cardiac arrhythmias and muscle weakness. The nurse should stop the source of excess potassium, which is the KCl infusion, and monitor the client's vital signs, electrocardiogram, and symptoms.

Choice B reason: This is not the correct answer because administering oral KCl is not the first or appropriate action that the nurse should take. Oral KCl would increase the potassium level in the blood, which is already too high. The nurse should avoid giving any potassium supplements or foods that are high in potassium, such as bananas, oranges, and potatoes.

Choice C reason: This is not the correct answer because encouraging fluids for dilution is not the first or effective action that the nurse should take. Fluids alone would not lower the potassium level in the blood, but rather dilute the concentration of other electrolytes, such as sodium and calcium. The nurse should administer fluids only as prescribed by the physician, and in conjunction with other treatments, such as diuretics, insulin, or sodium bicarbonate.

Choice D reason: This is not the correct answer because calling the pharmacy is not the first or priority action that the nurse should take. Calling the pharmacy may be necessary to obtain the medications that can lower the potassium level in the blood, such as diuretics, insulin, or sodium bicarbonate. However, the nurse should first stop the KCl infusion and notify the physician, who will order the appropriate medications and dosages.
