Chapter 13 : Central Nervous System Stimulants and Related Drugs Questions
Question 1 of 5
A patient has a new prescription for phentermine as part of the treatment for weight loss. Which information will the nurse include when teaching this patient about a stimulant such as phentermine? (Select all that apply.)
Correct Answer: B,C,D,E
Rationale: Phentermine should be taken in the morning to avoid insomnia, alongside supervised exercise and diet for weight loss, and with measures like mouth rinses to manage dry mouth. Avoiding caffeine prevents additive stimulant effects. Taking it after meals is not necessary, as timing is not meal-dependent.
Question 2 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 3 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 4 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 5 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.
