A nurse is preparing to administer epinephrine to a client who is experiencing anaphylaxis after a bee sting. The nurse should administer the medication by which of the following routes?
Intramuscular
Subcutaneous
Intravenous
Oral
The Correct Answer is A
Intramuscular injection is the preferred route for administering epinephrine in anaphylaxis because it provides rapid absorption and onset of action.
B is incorrect because subcutaneous injection has a slower absorption rate than intramuscular injection and may not provide adequate relief in an emergency situation.
C is incorrect because intravenous injection of epinephrine can cause severe adverse effects such as cardiac arrhythmias and hypertension and should be reserved for life-threatening situations when other routes are ineffective.
D is incorrect because oral administration of epinephrine is ineffective due to extensive first-pass metabolism in the liver.
