Answer:
The correct order in which light passes through the structures of the eye is cornea → pupil → lens → vitreous humor
Explanation:
Light and images are the stimuli that must be perceived by the eye for the sense of vision to be produced. These stimuli must go through some ocular structures before reaching the retinal photoreceptors, passing to the optic nerve and being conducted to the brain.
The order of ocular structures that light passes through before reaching the retina is
- <em><u>Cornea</u></em><em>, the outermost layer of the eye that covers the iris.</em>
- <em><u>Pupil</u></em><em>, which corresponds to the opening in the iris that regulates the passage of light.</em>
- <em><u>Lens</u></em><em>, which is the transparent structure that is found in the anterior chamber of the eye and allows focusing.</em>
- <em>The </em><em><u>vitreous humor</u></em><em> is a substance with gel consistency that is behind the lens and separates it from the retina.</em>
The correct ocular function, with respect to vision, depends on the integrity of all structures through which light must pass before reaching the retina.

Answer:
c) Whenever heartburn occurs (prn) Q.I.D.
Explanation:
- Antacids are OTC drugs (no prescription needed) used to treat heartburn. They are usually salts (aluminium, calcium or magnesium) that neutralize the excess of acid in the stomach.
- Examples of antacids are: Pepto Bismol (P&G), Maalox (SANOFI) and Tums (GSK)
- There are other types of medications that control heartburn, but they do it through a different mechanism: instead of neutralizing the excess of acid, they inhibit the production of acid in the stomach. These are: PPIs (Proton Pump Inhibitors) and H2 inhibitors/blockers. These medications have important side effects and interactions, which is why they shouldn't be taken instead of an antacid to relief sporadic heartburn symptoms.
- Ranitidine (Zantac, by SANOFI) is an example of an H2 inhibitor, and Pantoprazole (Protonix, by Pfizer) is an example of a PPI.
- People who present heartburn only from time to time and have no underlying reflux disease are not prescribed PPIs or H2 inhibitors. It is advised that they take antacids after meals when heartburn occurs, but not in a routinely manner and not for more than 2 weeks. If symptoms persist or worsen, clients should see a doctor.
- Diet and lifestyle changes are also recommended for people who present heartburn; these include: avoiding foods that trigger it such as fried and spicy food & carbonated beverages, eating smaller meals, maintaining a healthy weight, avoiding smoking, and avoiding lying down after eating.
