Answer:
Option D, drowsy
Step-by-step explanation:
Anti-histamine medications, like diphenhydramine, often have sedative properties that leave the patient feeling drowsy following administration of the medication. This is why the patient education includes informing the patient to avoid activities that require high levels of alertness such as driving and operating heavy machinery until the response to the medication is known, as well as educating the patient on the necessity to avoid alcohol and other central nervous system (CNS) depressants.
Medications that make the patient feel more alert are CNS stimulants such as methylphenidate (AKA Ritalin) indicated for patients with attention-deficit hyperactivity disorder (ADHD).
Medications that make the patient feel like they are in a dream state are likely opioid analgesics (e.g. morphine, oxycodone, codeine) that produce a sense of euphoria as a side effect and are indicated for patients in need of pain relief.
Medications that make the patient feel numbed are anesthetics like lidocaine or propofol used to purposefully reduce or inhibit what the patient can feel, locally or generally.
