Final answer:
Fentanyl's unique property is that it is reversible with naloxone; Versed may risk a paradoxical reaction in the elderly; Ketamine acts as a dissociative analgesic; and Propofol can often cause hypotension.
Step-by-step explanation:
The unique properties of each drug mentioned can be matched as follows:
- Versed (midazolam) – D) risks paradoxical reaction in the elderly.
- Fentanyl – A) reversible with naloxone.
- Ketamine – B) dissociative and analgesic.
- Propofol – C) often causes hypotension.
Naloxone is an opiate antagonist that can quickly reverse the effects of opioids like fentanyl, effectively treating overdose symptoms by restoring breathing in individuals experiencing respiratory depression. Ketamine is known for its dissociative anesthesia properties alongside its function as an analgesic. Propofol is a commonly used injectable anesthetic for the induction of unconsciousness that can lead to hypotension. Lastly, Versed, which is a type of Benzodiazepine, can sometimes result in paradoxical reactions, such as agitation or aggression, especially in elderly patients.
