While triaging the wounded from a disaster, you note that one of the wounded is not breathing, radial pulse is absent, capillary refill >2 seconds, and does not respond to your commands. What color tag is assigned?
Green
Yellow
Red
Black
The Correct Answer is D
During triage in a disaster situation, a color tagging system is often used to prioritize and categorize the injured based on the severity of their injuries and the urgency of medical attention required. The colors commonly used in triage are:
● Green tag: Minor injuries that are non-urgent and can typically wait for medical treatment.
● Yellow tag: Injuries that are significant but not immediately life-threatening, requiring medical attention within a few hours.
● Red tag: Critical injuries that are life-threatening but still salvageable with prompt medical intervention.
● Black tag: Injuries that are severe and unsurvivable or incompatible with life. This tag is assigned to individuals who are deceased or have injuries that are beyond the resources available for treatment.
In the given scenario, the absence of breathing, absent radial pulse, prolonged capillary refill, and unresponsiveness indicate a critical condition with no signs of life. Therefore, a black tag would be assigned to this individual.

Correct Answer is B
Explanation
Antihistamines primarily work by blocking the H1 receptors, which are the receptors responsible for mediating the actions of histamine in the body. By blocking these receptors, antihistamines prevent or reduce the effects of histamine, such as itching, sneezing, runny nose, and watery eyes. This is the main mechanism by which antihistamines provide their therapeutic effects. "Antihistamines block release of histamine from mast cells and basophils." This statement is incorrect. Antihistamines do not block the release of histamine; instead, they block the histamine receptors to prevent the effects of histamine.
"H1 antagonists can bind to H1 receptors, H2 receptors, and muscarinic receptors." This statement is incorrect. H1 antagonists, or H1 receptor blockers, specifically bind to H1 receptors and do not have significant affinity for H2 receptors or muscarinic receptors. "First-generation antihistamines are more selective than second-generation antihistamines." This statement is incorrect. First-generation antihistamines are generally less selective and can have more sedating and anticholinergic effects compared to second-generation antihistamines, which are designed to be more selective for H1 receptors and have reduced sedative properties.
Correct Answer is C
Explanation
0.9% Sodium chloride is a balanced isotonic solution that closely resembles the electrolyte composition of the extracellular fluid. It is commonly used to treat dehydration because it helps restore fluid volume and electrolyte balance in the body.
5% dextrose in Lactated Ringers: This solution is typically used for fluid and electrolyte replacement in patients who have significant fluid losses or imbalances, but it may not be the best choice for dehydration alone.
0.45% sodium chloride: This solution, also known as half-normal saline, has a lower concentration of sodium chloride and is often used for patients who require hypotonic fluids. It may not provide enough electrolyte replacement for a dehydrated patient. 3% Normal Saline: This solution has a higher concentration of sodium chloride and is typically used for specific indications, such as severe hyponatremia or in critical care settings. It is not the first-line choice for treating dehydration.
