Final answer:
C. 3 mL; 2 mL. The nurse should not administer more than 3 mL of medication per intramuscular injection site, except for the deltoid where the nurse should not administer more than 2 mL.
Step-by-step explanation:
The nurse should not administer more than 3 mL of medication per intramuscular injection site, except for the deltoid where the nurse should not administer more than 2 mL. This is because the maximum volume of medication that can be safely injected into the muscle is limited due to the risk of tissue damage. Injecting more than the recommended volume can lead to pain, inflammation, and other complications.
