Final answer:
It is true that if an initial dose of epinephrine is at the lower end of the dosage range, subsequent doses can be increased. Epinephrine is essential for treating anaphylactic shock, and additional doses may be needed if symptoms persist.
Step-by-step explanation:
If you administered a dose of epinephrine at the lower end of the dosage range, you can consider increasing subsequent doses is true. Epinephrine is the primary drug used to counteract the effects of anaphylactic shock, which is a severe allergic reaction that can be fatal if not treated promptly. Individuals with known severe allergies are advised to carry an epinephrine autoinjector, such as an EpiPen®, that can be used in the event of exposure to an allergen.
An initial dose of epinephrine will typically alleviate symptoms by raising blood pressure, relaxing bronchial smooth muscle to improve breathing, and modulating the heart rate. In situations where the initial dose is at the lower end and symptoms persist or recur, medical professionals may administer higher subsequent doses to fully control the anaphylactic reaction.
However, it is important to follow the guidance of healthcare providers when administering epinephrine and to always seek emergency medical attention following its use.
