The nurse has given medication instructions to a patient receiving phenytoin. Which statement by the patient indicates that the patient has an adequate understanding of the instructions?
"I will need to take extra care of my teeth and gums while on this medication."
"I will be able to stop taking this drug once the seizures stop."
"I can go out for a beer while on this medication."
"I can skip doses if the side effects bother me."
The Correct Answer is A
A. "I will need to take extra care of my teeth and gums while on this medication.": Phenytoin can cause gum overgrowth (gingival hyperplasia), so taking extra care of oral hygiene is important.
B. "I will be able to stop taking this drug once the seizures stop.": Phenytoin is typically used as a long-term therapy for seizure control; stopping abruptly can lead to rebound seizures.
C. "I can go out for a beer while on this medication.": Alcohol consumption may interact with phenytoin and should be avoided or limited.
D. "I can skip doses if the side effects bother me.": Skipping doses of phenytoin can lead to inadequate seizure control and should not be done without consulting a healthcare provider.

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.
Correct Answer is ["0.6"]
Explanation
To find out how many milliliters (mL) of methylnaltrexone should be administered to achieve a dose of 12 mg, we need to set up a proportion based on the available concentration.
Given:
- Methylnaltrexone concentration: 8 mg per 0.4 mL
- Desired dose: 12 mg
We can set up the proportion as follows:
8 /0.4 = 12 / x
Where ( x ) is the unknown amount of methylnaltrexone in milliliters.
To solve for ( x ), we can cross multiply and then divide:
8x = 0.4 12
8x = 4.8
x = 4.8/8
x = 0.6
Therefore, the nurse should administer 0.6 mL of methylnaltrexone.
