A nurse monitors a client prescribed atomoxetine for attention-deficit/hyperactivity disorder (ADHD). Which adverse effect should the nurse assess for?

Methylphenidate is a stimulantmedication that enhances dopamineand norepinephrineactivity in the prefrontal cortex, improving attention and impulse control. Common adverse effects include insomnia, decreased appetite, headache, abdominal pain, and potential risk of seizures. Cardiovascular effects usually involve mild hypertension or tachycardia, not hypotension.

Rationale for correct answers:

2.Decreased appetite is a frequent side effect due to stimulant-induced suppression ofdopaminergicpathwaysregulating hunger. This can lead to weight loss in children, requiring monitoring of growth and nutritional intake.

4.Insomnia occurs because stimulantsincrease CNS activity. Evening dosing exacerbates sleep disturbance. Nurses should advise morning administration and monitor sleep hygiene to reduce impact on rest.

5.Headache is a common adverse effect linked to stimulant-induced changes inneurotransmitterbalance. It is usually mild but can interfere with adherence, requiring symptomatic management.

6.Seizures are a rare but serious adverse effect. Stimulants lower the seizure threshold, especially in clients with preexisting epilepsy. Monitoring neurological status is essential to detect early warning signs.

Rationale for incorrect answers:

1.Hypotension is not typical of methylphenidate. Stimulants usually cause hypertension or tachycardia due to sympathetic activation. Monitoring blood pressure is important, but hypotension is not expected.

3.Sedation is inconsistent with stimulant pharmacology. Methylphenidate increases alertness and activity, not drowsiness. Sedationwould suggest another drug effector comorbidity, not methylphenidate.

Test-taking strategy

• Identify the main drug: methylphenidate, a stimulant.
• Recall stimulant side effects: insomnia, appetite suppression, headache, abdominal pain, possible seizures.
• Rule out distractors:
  • Hypotension is not expected; stimulants raise blood pressure.
  • Sedation contradicts stimulant pharmacology.
• Focus on adverse effects consistent with CNS stimulationand appetite suppression.
• Use elimination methodology: remove options inconsistent with stimulant effects.
• Correct answers emerge by matching stimulant pharmacodynamics to expected clinical manifestations.

Take home points

• Methylphenidate commonly causes decreased appetite, insomnia, and headache.
• Seizures are rare but serious adverse effects requiring monitoring.
• Hypotension and sedation are not expected with stimulant therapy.
• Nurses must monitor growth, sleep, and neurological status in children on methylphenidate.

Dextroamphetamine is a stimulantthat enhances dopamineand norepinephrineactivity, improving attention and impulse control in ADHD. However, it frequently causes anorexiaand weight loss due to appetite suppression. Administering the drug after meals helps reduce nutritional impact by allowing adequate intake before appetite suppression begins.

Rationale for correct answer:

3.Administering dextroamphetamine after meals minimizesanorexiaby ensuring the child eats before appetite suppression occurs. This intervention directly addresses imbalanced nutrition and supports growth and weight maintenance in pediatric ADHD clients.

Rationale for incorrect answers:

1.Monitoring output and sleep patterns daily is important for stimulant therapy but does not directly addressnutrition. It helps detect insomnia or urinary changes, yet it fails to correct anorexia-related weight loss.

2.Administering medication with food prevents nausea, not anorexia. Stimulants primarily suppress appetite rather than cause gastrointestinal upset. This intervention does not resolve the nutritional deficit associated with dextroamphetamine.

4.Increasing fiber and fluid intake prevents constipation, a possible side effect of stimulants. While beneficial, it does not address anorexia or weight loss, which are the primary nutritional concerns in this scenario.

Test-taking strategy

• Identify the main issue: imbalanced nutrition due to anorexia from stimulant therapy.
• Recall stimulant side effects: appetite suppression, insomnia, headache, abdominal pain.
• Rule out distractors:
  • Monitoring sleep/output = general care, not nutrition.
  • With food = prevents nausea, not anorexia.
  • Fiber/fluid = prevents constipation, not anorexia.
• Focus on the intervention that directly improves nutritional intake.
• Correct answer emerges by matching anorexia management with timing of medication administration.

Take home points

• Stimulants like dextroamphetamine suppress appetite, leading to anorexia and weight loss.
• Administering medication after meals helps preserve nutritional intake.
• Other interventions address side effects but not anorexia.
• Nurses must monitor growth and weight in children on stimulant therapy.
