Answer:
"The contractions do not seem as painful as before."
Step-by-step explanation:
Nalbuphine is a opined analgesic that is commonly used for pain management. Medical professionals will inject this to the patient's vein or muscle to increase the threshold of the recipients' pain perception.
This substance is very common to be used during childbirth to reduce the excruciating amount of pain that the mother felt when the babies come out from her sex organ.
As a procedure , nurses are required to make sure that the substance is taking effect by directly asking the patient how they felt. Responses such as "The contractions do not seem as painful as before" indicates that the patient's pain threshold has been increased and the drug is starting to take effect.
