Final answer:
The nurse should include morphine in the count of controlled substances. Acetaminophen and ibuprofen are not considered controlled substances. Antibiotics are also not typically included in controlled substance counts.
Step-by-step explanation:
The nurse should include morphine in the count of controlled substances. Morphine is a powerful opioid pain medication that is commonly used in healthcare settings for severe pain relief, such as before and after surgical procedures. It is classified as a controlled substance due to its potential for abuse and addiction.
Acetaminophen and ibuprofen, also known as paracetamol and NSAIDs, are not considered controlled substances, as they do not have the same potential for abuse or addiction. These medications are commonly used for pain relief but have different mechanisms of action compared to opioids like morphine.
Antibiotics, on the other hand, are not typically included in controlled substance counts as they are used to treat infections and do not have the same potential for abuse or addiction as opioids.
