Hypertension
Muscle rigidity of jaw and upper chest
Tachypnea
Skin mottling
High body temperature
Correct Answer : A,C,D,F
Muscle rigidity is a hallmark sign of malignant hyperthermia. It commonly affects the muscles of the jaw and upper chest.
Malignant hyperthermia can lead to rapid and shallow breathing, resulting in tachypnea. Malignant hyperthermia is characterized by a significant increase in body temperature, often exceeding 38.8°C (101.8°F).
Malignant hyperthermia can cause irregular heart rhythms or dysrhythmias, including tachycardia or arrhythmias.
The manifestations of hypertension and skin mottling are not typically associated with malignant hyperthermia. Hypertension (high blood pressure) is more commonly seen in conditions such as hypertensive emergencies or certain cardiovascular disorders. Skin mottling, which refers to irregular or patchy skin coloration, is not a specific manifestation of malignant hyperthermia.

Explanation
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 D
Explanation
Nonsteroidal anti-inflammatory drugs (NSAIDs) are a class of medications commonly used to relieve pain, reduce inflammation, and lower fever. They work by inhibiting the production of prostaglandins, which are substances in the body that play a role in pain and inflammation. Celecoxib specifically belongs to the subclass of NSAIDs known as selective COX-2 inhibitors, which target the enzyme cyclooxygenase-2 (COX-2). By selectively inhibiting COX-2, celecoxib helps to reduce inflammation and pain while potentially minimizing the gastrointestinal side effects associated with traditional non-selective NSAIDs.
