Phenothiazines are contraindicated in patients with suspected or established subcortical brain damage. Phenothiazines are a class of drugs that have antipsychotic, antiemetic, and sedative effects. They act by blocking dopamine receptors in the brain and can cause extrapyramidal symptoms, hypotension, and anticholinergic effects.

Choice B is wrong because phenothiazines are not contraindicated in patients with ischemic heart disease.

However, they can cause orthostatic hypotension and cardiac arrhythmias, so they should be used with caution and monitored closely in these patients.

Choice C is wrong because phenothiazines are not contraindicated in pediatric patients.

However, they can cause sedation, hypotension, and extrapyramidal symptoms, so they should be used with caution and at lower doses in these patients.

Choice D is wrong because phenothiazines are not contraindicated in patients with type 2 diabetes.

However, they can cause hyperglycemia and weight gain, so they should be used with caution and monitored closely in these patients.

Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. Diabetic retinopathy is caused by damage to the blood vessels of the retina, which is the light-sensitive tissue at the back of the eye. This damage can reduce the oxygen supply to the retina and lead to vision problems.

Choice A is wrong because cells in the eye can reproduce normally, but they may not function properly due to high blood sugar levels or lack of oxygen.

Choice B is wrong because diabetic retinopathy does not affect the production of aqueous humor, which is the fluid that fills the front part of the eye.

However, diabetes can cause another eye condition called glaucoma, which is caused by increased pressure from too much aqueous humor.

Choice C is wrong because diabetic retinopathy does not affect the nerve innervations throughout the eye.

However, diabetes can cause another eye condition called diabetic neuropathy, which is caused by damage to the nerves that control eye movement and pupil dilation.
