The nurse administers metoclopramide to the client with what condition?

This is because proton pump inhibitors (PPIs) are drugs that block the enzyme that produces hydrochloric acid in the stomach, thereby reducing the amount of acid secreted into the lumen. PPIs are commonly used to treat peptic ulcer disease and gastroesophageal reflux disease.

Choice B. Histamine-2 antagonist is wrong because histamine-2 antagonists (H blockers) are drugs that block the action of histamine on the parietal cells of the stomach, thereby reducing the amount of acid secreted into the lumen.

However, PPIs are more potent and effective than H blockers in suppressing acid secretion.

Choice C. Prostaglandin is wrong because prostaglandins are substances that protect the stomach lining from the damaging effects of acid and other factors.

Prostaglandins do not directly affect the secretion of acid into the lumen, but they may increase the production of mucus and bicarbonate that buffer the acid.

Choice D. Antipeptic agent is wrong because antipeptic agents are drugs that form a protective barrier over the ulcer crater, preventing further damage from acid and pepsin.

Antipeptic agents do not affect the secretion of acid into the lumen, but they may enhance healing by creating a favorable environment for tissue repair.

Normal ranges for hydrochloric acid secretion in the stomach are 1.5 to 3.5 liters per day, with a pH of 1.5 to 3.53.

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.
