A patient is ordered a phenothiazine antiemetic for treatment of nausea and vomiting associated with chemotherapy. The nurse will be evaluating for a positive effect. At what time should the nurse administer the drug?

as requested by the patient.

1 hour after chemotherapy administration.

The night before the treatment, the day of the treatment, and for 24 hours after the treatment.

the day of treatment.

Answer and Explanation

The Correct Answer is C

A. As requested by the patient.

Administering the drug only when requested by the patient may not provide adequate prophylaxis against chemotherapy-induced nausea and vomiting. These medications are often prescribed on a schedule to prevent symptoms rather than treating them reactively.

B. 1 hour after chemotherapy administration.

Waiting until 1 hour after chemotherapy administration may not cover the full period during which nausea and vomiting are likely to occur. The administration schedule for antiemetics is often more extended to provide better coverage.

C. The night before the treatment, the day of the treatment, and for 24 hours after the treatment.

This is the correct choice. Administering phenothiazine antiemetics according to this schedule helps ensure continuous coverage during the critical period when chemotherapy-induced nausea and vomiting are most likely to occur.

D. The day of treatment.

Administering the drug only on the day of treatment may not provide sufficient coverage for the entire duration when chemotherapy-induced nausea and vomiting can occur. Again, the schedule mentioned in option C is more comprehensive for prevention.

Correct Answer is A

Explanation

A. Before breakfast or lunch

Methylphenidate (Ritalin), a stimulant medication commonly used to treat attention deficit hyperactivity disorder (ADHD), is usually administered before breakfast or lunch for maximum effectiveness. This schedule helps align the peak concentration of the medication with the times when increased focus and attention are often needed, such as during school hours.

B. With meals

While it can be administered with meals, the goal is often to have the medication take effect before meals to help with focus and attention during activities like school or work.

C. After dinner

Administering methylphenidate after dinner may interfere with the patient's ability to fall asleep, as the medication can cause insomnia. It is generally recommended to avoid administering it in the late afternoon or evening.

D. At bedtime

Administering methylphenidate at bedtime is not appropriate due to the potential for insomnia. The stimulant effect of the medication is not aligned with the patient's sleep-wake cycle.

A. a learning disorder and muscle paralysis B. nervousness and sleeplessness C. hyperactivity and decreased attention span D. hyperactivity and nervousness

Correct Answer is C

Explanation

A. A learning disorder and muscle paralysis

This description does not align with the typical symptoms of ADHD. ADHD is characterized by core symptoms of inattention, hyperactivity, and impulsivity. Muscle paralysis is not a recognized symptom of ADHD.

B. Nervousness and sleeplessness

While some individuals with ADHD may experience difficulties with sleep, nervousness and sleeplessness are not the primary symptoms of ADHD. ADHD is more characterized by difficulties with attention, hyperactivity, and impulsivity.

C. Hyperactivity and decreased attention span

This is the correct choice. Hyperactivity and a decreased attention span are core symptoms of ADHD. Children with ADHD often display impulsive behaviors, have difficulty sustaining attention, and may be overly active.

D. Hyperactivity and nervousness

While hyperactivity is a common symptom of ADHD, nervousness is not typically described as a core symptom. ADHD is more characterized by impulsivity, hyperactivity, and attention difficulties.
