Question

The deltoid muscle is commonly used for injection of all of the following, except:

A) Tetanus boosters in adults
B) Rabies vaccines after exposure
C) Penicillin
D) Vitamin B12
E) Hepatitis B vaccine

Answer 1

All the injections listed, including tetanus boosters, rabies vaccines, penicillin, vitamin B12, and hepatitis B vaccines, are known to be administered into the deltoid muscle. The question seems to contain an inaccuracy as it implies one of the listed medications is not commonly injected into the deltoid muscle when in fact, they all are.

Step-by-step explanation:

The deltoid muscle, a large, triangular-shaped muscle that covers the shoulder, is a common site for intramuscular injections due to its size and accessibility. Typical injections into the deltoid include tetanus boosters, rabies vaccines, penicillin, vitamin B12, and the hepatitis B vaccine. The question asks about which of these is not commonly injected into the deltoid muscle. All the listed injections—tetanus boosters in adults, rabies vaccines after exposure, penicillin, vitamin B12, and hepatitis B vaccine—can be administered into the deltoid muscle. Therefore, the question seems to contain an inaccuracy as all options given are indeed administered into the deltoid muscle.
