Why does the nurse administer lorazepam intramuscularly (IM) to the patient rather than into the subcutaneous tissue?
Correct answer
C
Rationale
Rationale: The nurse administers lorazepam intramuscularly (IM) to the patient because the medication will be absorbed and begin to work more quickly when given IM. IM injections have a faster onset of action compared to subcutaneous injections due to the rich blood supply in the muscle tissue, allowing for quicker absorption and distribution of the medication into the bloodstream. This rapid absorption is particularly beneficial in emergency situations where a prompt therapeutic effect is needed.
Summary of Incorrect Choices:
A: The patient's body fat does not determine the route of administration for lorazepam.
B: Needle size does not dictate the route of administration; it is based on the medication and desired effects.
D: The risk of bleeding is not a factor in choosing between IM and subcutaneous injections for lorazepam.
