The nurse is teaching the client with a new prescription for ibandronate how to take the medication.
Which instruction provided by the nurse is correct?

The nurse should advise the client to avoid aluminum salts because they can increase the risk of aluminum toxicity when taken with sucralfate. Sucralfate forms a protective coating over the ulcer and binds to aluminum in the stomach.

Choice A is wrong because Milk of Magnesia is a magnesium-based antacid that can cause diarrhea, but does not interact with sucralfate.

Choice B is wrong because Calcium carbonate is a calcium-based antacid that can cause constipation, but does not interact with sucralfate.

Choice D is wrong because Proton pump inhibitors are drugs that reduce the production of stomach acid and can help heal ulcers.

They do not interact with sucralfate.

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.
