Which of the following fingers is the preferred capillary puncture site for a patient older than 1 year?

A. Blood vessel constriction: Epinephrine is a vasoconstrictor, meaning it causes blood vessels to narrow, which increases blood pressure and is often used in emergency situations like anaphylaxis.
B. Calming effect: Epinephrine does not have a calming effect; it stimulates the fight-or-flight response, increasing heart rate, blood pressure, and alertness.
C. Decrease in blood pressure: Epinephrine increases blood pressure by causing vasoconstriction, not a decrease.
D. Pain control: Epinephrine is not used for pain control; it is used to treat severe allergic reactions, asthma attacks, and cardiac arrest.

A. Bluish lips, cough, and difficulty breathing: These symptoms can indicate poisoning, particularly from substances that affect oxygen levels or respiratory function.
B. Itchy eyes, sinus congestion, and drainage: These symptoms are more commonly associated with allergies or upper respiratory infections rather than poisoning.
C. Increase in thirst, urination, and hunger: These symptoms are typically associated with conditions like diabetes rather than poisoning.
D. Heat intolerance, increased energy, and sweating: These symptoms are more indicative of hyperthyroidism or other endocrine disorders rather than poisoning.
