Final answer:
Deep tendon reflexes do not need to be checked before administering opioids as opioids primarily affect the central nervous system, not deep tendon reflexes.
Step-by-step explanation:
Checking deep tendon reflexes is not typically required before administering opioids. Deep tendon reflexes, also known as stretch reflexes, are tested to assess the function of the nervous system and to detect any abnormalities. However, opioids primarily affect the central nervous system and do not directly impact deep tendon reflexes. It is important to monitor deep tendon reflexes during opioid therapy to ensure the continued safety and effectiveness of the treatment.
