Chapter 13 : Central Nervous System Stimulants and Related Drugs Questions
Question 1 of 5
A patient has just received an injection of onabotulinumtoxin A. The nurse will monitor for which adverse effects? (Select all that apply.)
Correct Answer: B,E
Rationale: Onabotulinumtoxin A (Botox) carries a Black Box Warning for toxin spread beyond the injection site, which may cause dysphagia and breathing difficulties. Insomnia, weight gain, and GI upset are not commonly associated adverse effects.
Question 2 of 5
The order reads: 'Give atomoxetine 0.5 mg/kg/day once daily in the morning before school.' The child weighs 88 pounds. Identify how many milligrams will be administered per dose.
Correct Answer: 20 mg
Rationale: Convert 88 pounds to kilograms: 88 ?· 2.2 = 40 kg. Calculate dose: 0.5 mg/kg/day ?? 40 kg = 20 mg/day.
Question 3 of 5
A patient is receiving instructions regarding the use of caffeine. The nurse shares that caffeine should be used with caution if which of these conditions is present?
Correct Answer: A
Rationale: Caffeine can exacerbate peptic ulcers by increasing gastric acid secretion, which may worsen the condition. It is not contraindicated in migraine headaches, asthma, or kidney stones, though it may have varying effects on these conditions.
Question 4 of 5
A patient who started taking orlistat 1 month ago calls the clinic to report some 'embarrassing' adverse effects. She tells the nurse that she has had episodes of 'not being able to control my bowel movements.' Which statement is true about this situation?
Correct Answer: D
Rationale: Orlistat's gastrointestinal side effects, such as fecal incontinence, are related to its mechanism of inhibiting fat absorption. Restricting dietary fat to less than 30% of total calories can reduce these effects. They are not expected to diminish entirely without dietary changes, stopping the drug is not necessary, and increasing fat intake would worsen the effects.
Question 5 of 5
A 6-year-old boy has been started on an extended-release form of methylphenidate hydrochloride for the treatment of attention deficit hyperactivity disorder (ADHD). During a follow-up visit, his mother tells the nurse that she has been giving the medication at bedtime so that it will be 'in his system' when he goes to school the next morning. What is the nurse's appropriate evaluation of the mother's actions?
Correct Answer: D
Rationale: Methylphenidate, a CNS stimulant, can cause insomnia if taken close to bedtime. Administering it 4 to 6 hours before bedtime helps minimize sleep disturbances while maintaining therapeutic levels during the day. Bedtime dosing, school-time dosing, or meal-dependent administration are not appropriate for extended-release formulations.
