A snake bite quiz came across one of my news feeds. Thought it was interesting so below is a copy paste (I'd give the sight but to access you have to sign up). Answers are at the bottom. Hope you enjoy.
Most snakebites are innocuous and are delivered by nonpoisonous species. North America is home to 25 species of poisonous snakes. Worldwide, only about 15% of the more than 3000 species of snakes are considered dangerous to humans. Although death is rare, local complications from envenomation may occur.
1. Which of the following is accurate regarding the epidemiology of snakebites?
A. Most snakebites are reported in white females
B. Most patients who present with snakebites are aged 12-17 years
C. Most snakebites are reported on the foot or leg
D. Most snakebites are reported from April to October
2. Which of the following is accurate about the presentation of snakebites?
A. Soft pitting edema most commonly develops in the first 10-15 minutes
B. Respiratory distress is more common with coral snake bites
C. Although alarming, early and intense pain is not necessarily a sign of significant envenomation
D. Neuromuscular blockade is more common with rattlesnake bites
3. Which of the following statements is accurate regarding snakebite wounds?
A. The overwhelming majority of viper bites are dry
B. Cobra bites typically result in envenomation
C. Rattlesnakes bites cause limited local effects but significant neurologic compromise
D. Copperhead bites are generally limited to localized tissue destruction
4. Which of the following statements is accurate about the treatment of snakebites?
A. A negative pressure venom extraction device is often helpful
B. Incision across the fang marks is typically recommended
C. Limiting venom spread may be deleterious in pit viper evenomation
D. Tourniquets are routinely indicated
Answers:
D. White males account for most victims. Most snakebites occur in individuals aged 18-28 years, with most bites located on an extremity, especially the hand. The vast majority of reported snakebites occur from April to October.
B. Neuromuscular blockade and respiratory distress are more common with coral snakes. Soft pitting edema generally develops over 6-12 hours but may start within 5 minutes. Early and intense pain implies significant envenomation.
D.If no symptoms occur within 8-12 hours, no evenomation may have occurred. This is called a dry bite. At least 25% of viper bites are dry, but as many as 50% may be venomous. Copperhead bites are generally limited to localized tissue destruction. Rattlesnakes can cause both localized symptoms and systemic toxicity. Cobra bites frequently do not result in envenomation and are so-called dry bites.
C. In some studies no benefit was demonstrated when a negative pressure venom extraction device was evaluated; additional injury can result. Incision across fang marks is not recommended. Mouth suction is contraindicated. Lymphatic constriction bands and pressure immobilization techniques may inhibit the spread of venom, but whether they improve outcome is not clear. Limiting venom spread actually may be deleterious for pit viper envenomation if it increases local necrosis or compartment pressure. Tourniquets are not recommended.

Being told you're delusional does not necessarily mean you're mental.
