A patient has been taking phenobarbital for 2 weeks as part of his therapy for epilepsy. He tells the nurse that he feels tense and that the least little thing bothers him now. Which is the correct explanation for this problem?

These are adverse effects that usually subside after a few weeks.

The drug must be stopped immediately because of possible adverse effects.

This drug causes deprivation of REM sleep and may cause the inability to deal with normal stress.

This drug causes the rapid eye movement (REM) sleep period to increase, resulting in nightmares and restlessness.

Answer and Explanation

The Correct Answer is C

A.   These are adverse effects that usually subside after a few weeks: While some adverse effects of phenobarbital may diminish over time, the symptoms described by the patient are more likely related to its impact on REM sleep.
B.   The drug must be stopped immediately because of possible adverse effects: Stopping phenobarbital abruptly can lead to withdrawal symptoms and potential rebound seizures; discontinuation should be done gradually under medical supervision.
C.   This drug causes deprivation of REM sleep and may cause the inability to deal with normal stress: Phenobarbital is known to disrupt REM sleep, leading to emotional lability, irritability, and difficulty coping with stress.
D.   This drug causes the rapid eye movement (REM) sleep period to increase, resulting in nightmares and restlessness: Phenobarbital actually decreases REM sleep, which can lead to disturbances in sleep patterns and mood changes.

Correct Answer is A

Explanation

A. The last dose of medication should be given 4 to 6 hours before bedtime to diminish insomnia: Methylphenidate is a stimulant medication commonly used to treat ADHD.
Administering it at bedtime may interfere with sleep onset and lead to insomnia. It's important to follow the prescribed dosing schedule to optimize symptom control during waking hours while minimizing adverse effects on sleep.
B. The medication should be taken with meals for optimal absorption: While taking

methylphenidate with meals may help reduce gastrointestinal side effects, the timing of administration relative to bedtime is more relevant to address in this scenario.
C. The medication should not be taken until he is at school: Delaying medication until the child is at school may result in inadequate symptom control during the morning when ADHD
symptoms are often most problematic.

D. She is giving him the medication dosage appropriately: Administering methylphenidate at bedtime is not appropriate and may lead to insomnia rather than optimizing symptom control during the day.

D. Levodopa/carbidopa is a medication commonly used in the treatment of Parkinson's disease to manage motor symptoms such as tremor, rigidity, and bradykinesia. The nurse should provide
