Medications for diarrhea that work by absorbing excess fluid in fecal matter in the colon without affecting transport processes across the membrane are known as?
Laxatives
Antimotility agents
Adsorbents
Bulk-forming agents
The Correct Answer is C
A. Laxatives are used to relieve constipation by promoting bowel movements, not for treating diarrhea.
B. Antimotility agents work by slowing down the movement of the intestines, which can reduce diarrhea, but they do not specifically absorb excess fluid in the fecal matter.
C. Adsorbents, such as activated charcoal or kaolin-pectin, work by absorbing excess fluid in the fecal matter in the colon, which helps to reduce diarrhea without affecting transport processes across the intestinal membranes.
D. Bulk-forming agents, like psyllium, absorb water and increase the bulk of stool, which is used for constipation rather than diarrhea.

Correct Answer is B
Explanation
A. While inflammation plays a role in restoring functional cells, it is not the ultimate goal. The primary purpose of inflammation is to prepare the site for healing, which includes clearing out damaged cells and pathogens.
B. Inflammation is a vital process that helps prepare the site for healing by facilitating the removal of dead tissue and pathogens, allowing for tissue repair. It also promotes the formation of new tissue.
C. Platelet aggregation and clotting are part of the inflammatory process, but the ultimate goal of inflammation is not to increase platelets but to prepare the site for repair and healing.
D. Inflammatory mediators typically cause vasodilation to increase blood flow to the affected area, not vasoconstriction. This helps deliver nutrients, oxygen, and immune cells to the site of injury.
Correct Answer is D
Explanation
A. A superficial partial thickness burn affects only the outermost layer of skin (epidermis) and causes redness and pain, but it doesn't usually cause blisters.
B. A full-thickness burn involves the destruction of all layers of the skin, including the epidermis, dermis, and sometimes underlying tissue. This type of burn typically causes a white or charred appearance and may not be painful due to nerve damage.
C. Dermal thickness burn is not a standard classification of burn depth. Burns are typically classified into superficial, partial-thickness, and full-thickness categories.
D. A deep partial-thickness burn involves damage to both the epidermis and dermis, causing redness, swelling, and blistering. This is the most likely classification for a sunburn with redness and blistering.
