ADHD diagnosis requires symptoms present in 2 or more settings, which is why collateral information matters as much as the office visit. These questions cover the diagnostic criteria and validated rating scales, differentiating ADHD from anxiety and learning disorders, stimulant versus non-stimulant therapy, the cardiovascular screening done before starting a stimulant, and ongoing monitoring. Every rationale is pitched at Family Nurse Practitioner (FNP-BC / FNP-C) board level.
Question 1
A 12-year-old boy on extended-release mixed amphetamine salts for three years presents for an annual exam. His height velocity has dropped from the 50th to the 25th percentile. His academic performance is stable. What is the most appropriate management strategy?
- A) Discontinue the amphetamine and start immediate-release clonidine.
- B) Order a bone age radiograph to assess development.
- C) Institute structured medication holidays during the summer break.✓
- D) Switch to an equivalent dose of extended-release methylphenidate.
💡 Key Takeaway
Drug holidays during low-demand periods help mitigate long-term growth deceleration from stimulant medications.
Show rationale
Long-term central nervous system stimulant use can cause clinically significant growth velocity deceleration in pediatric patients. Instituting structured medication holidays during periods of lower academic demand, such as the summer break, allows for necessary catch-up growth without compromising the child's academic performance during the school year. Discontinuing the amphetamine and starting immediate-release clonidine is inappropriate because alpha-agonists are generally less effective as monotherapy for core inattentive ADHD symptoms. Ordering a bone age radiograph to assess development is an unnecessary diagnostic expense because mild growth suppression is a known, reversible pharmacological effect of this medication class. Switching to an equivalent dose of extended-release methylphenidate will not resolve the underlying issue, as growth suppression is a well-documented class effect shared by all central nervous system stimulants.
Question 2
A 55-year-old male with stage 3 chronic kidney disease and hypertension needs a colonoscopy. Which bowel preparation instruction is most appropriate for the FNP to provide today?
- A) Take a sodium phosphate preparation as directed.
- B) Take a polyethylene glycol preparation as directed.✓
- C) Take a magnesium citrate preparation as directed.
- D) Take a sodium picosulfate preparation as directed.
💡 Key Takeaway
Polyethylene glycol is the safest bowel preparation for patients with chronic kidney disease due to its osmotic neutrality.
Show rationale
Patients with chronic kidney disease are at high risk for severe fluid shifts and electrolyte abnormalities during bowel preparation. Polyethylene glycol (PEG) is an osmotically balanced, non-absorbable solution that is considered the safest option for these patients, making Option B correct. Option A is incorrect because sodium phosphate preparations carry a black box warning for acute phosphate nephropathy and are strictly contraindicated in CKD. Option C is incorrect because magnesium citrate can lead to dangerous hypermagnesemia in patients with impaired renal clearance. Option D is incorrect because sodium picosulfate with magnesium oxide is an osmotic stimulant laxative that can also cause significant volume depletion and electrolyte derangements, increasing the risk of acute kidney injury in patients who already have compromised baseline renal function.
Question 3
An 8-year-old boy with newly diagnosed ADHD is in the clinic to discuss medication options. His medical history is unremarkable but his father died suddenly at age 32 from an undiagnosed condition. Which action is most appropriate before initiating stimulant therapy?
- A) Initiate a long-acting methylphenidate daily formulation.
- B) Order a baseline electrocardiogram prior to prescribing.✓
- C) Prescribe a non-stimulant medication like oral atomoxetine.
- D) Refer the child for an outpatient sleep evaluation.
💡 Key Takeaway
A family history of sudden cardiac death requires an ECG before starting ADHD stimulant medications.
Show rationale
Stimulants can increase heart rate and blood pressure. While routine ECGs are not required for all children starting stimulants, a baseline electrocardiogram is strongly recommended for patients with a family history of sudden cardiac death or structural heart defects. Option A ignores the cardiac risk. Option C might be considered later but does not address the immediate need to evaluate cardiac risk if a stimulant is the preferred first-line treatment. Option D is unnecessary because there are no sleep complaints mentioned in the scenario.
Question 4
A 65-year-old presents with a bilateral hand tremor when drinking from a cup. The patient also exhibits nodding head movements and notes the shaking improves after a glass of wine. Which diagnosis is most likely?
- A) Idiopathic essential tremor syndrome✓
- B) Parkinson disease resting tremor
- C) Cerebellar intention tremor syndrome
- D) Enhanced physiologic tremor syndrome
💡 Key Takeaway
Essential tremors are bilateral action tremors that often involve the head and improve with alcohol consumption.
Show rationale
Essential tremor is characterized by bilateral kinetic tremors that often involve the head and typically improve with alcohol intake. Parkinson disease presents with an asymmetric, unilateral resting tremor that does not involve isolated head nodding. Cerebellar tremor worsens as the target is reached and involves ataxia. Enhanced physiologic tremor is linked to anxiety or stimulants and does not improve with alcohol.
Question 5
Before prescribing fluoxetine to a 16-year-old presenting with depressive symptoms, what critical assessment must the nurse practitioner complete to prevent adverse psychiatric outcomes?
- A) Evaluate the patient for past manic episodes.✓
- B) Assess the patient for generalized anxiety symptoms.
- C) Screen the patient for attention deficit traits.
- D) Test the patient for illicit substance dependence.
💡 Key Takeaway
Screening for bipolar disorder is mandatory before starting an SSRI to prevent medication-induced manic episodes.
Show rationale
Prescribing an SSRI to a patient with undiagnosed bipolar disorder can precipitate a manic episode. Therefore, it is critical to screen all patients presenting with depression for a history of mania or hypomania before initiating antidepressant therapy. While assessing for anxiety, attention deficit traits, and substance use are important components of a comprehensive psychiatric evaluation, failing to identify bipolar disorder poses the most immediate risk for a severe, medication-induced adverse psychiatric event.
Question 6
A 9-year-old boy is diagnosed with ADHD. Before initiating extended-release dexmethylphenidate, the nurse practitioner reviews his history. He has a BMI in the 10th percentile and a history of picky eating. Which initial plan of care modification is most appropriate?
- A) Prescribe an oral non-stimulant medication to preserve appetite.
- B) Initiate the stimulant concurrently with an appetite stimulant.
- C) Start a conservative stimulant dose and monitor weight.✓
- D) Delay all pharmacological treatment until his BMI normalizes.
💡 Key Takeaway
Children with low baseline BMI require conservative stimulant dosing and close growth monitoring rather than treatment avoidance.
Show rationale
Pediatric patients presenting with a low baseline BMI are at a significantly heightened risk for complications stemming from stimulant-induced anorexia. The safest and most appropriate approach is to start a conservative stimulant dose and closely monitor the patient's weight while proactively optimizing meal timing. Prescribing an oral non-stimulant medication to preserve appetite is incorrect because non-stimulants like atomoxetine also suppress appetite, and alpha-agonists are generally less effective for core symptoms. Initiating the stimulant concurrently with an appetite stimulant introduces unnecessary and potentially harmful polypharmacy before evaluating the child's actual tolerance to the primary drug. Delaying all pharmacological treatment until his BMI normalizes inappropriately denies the child the established first-line, evidence-based treatment for his neurodevelopmental condition based solely on a theoretical risk.
Question 7
A 76-year-old taking tramadol for shoulder pain and citalopram for depression presents with sudden agitation, tremor, and diaphoresis. Which clinical assessment is most urgent?
- A) Assess the patient for acute acetaminophen toxicity
- B) Evaluate the patient for acute gastrointestinal bleeding
- C) Assess the patient for acute serotonin syndrome✓
- D) Evaluate the patient for acute opioid withdrawal
💡 Key Takeaway
Tramadol has SNRI properties and can precipitate life-threatening serotonin syndrome when combined with SSRI antidepressants.
Show rationale
Tramadol is a weak opioid that also inhibits the reuptake of serotonin and norepinephrine. When combined with an SSRI like citalopram, it significantly increases the risk of serotonin syndrome, which presents with autonomic instability, altered mental status, and neuromuscular hyperactivity. Acetaminophen toxicity primarily causes silent hepatic injury initially, not acute tremors. Gastrointestinal bleeding presents with melena or anemia, typically linked to NSAIDs. Opioid withdrawal causes similar autonomic symptoms but occurs upon abrupt cessation, not during active concurrent use of tramadol.
Question 8
A 9-year-old boy is evaluated for inattention. His teacher reports he is disruptive during reading class, refuses to read aloud, and frequently loses focus. His parents report he plays complex board games at home for hours without any distraction. Which action should the Family Nurse Practitioner take?
- A) Initiate a trial of a long-acting stimulant medication.
- B) Diagnose the child with combined type hyperactivity disorder.
- C) Refer the child for comprehensive psychoeducational learning testing.✓
- D) Recommend strict behavioral modification strategies for the classroom.
💡 Key Takeaway
Task-specific inattention and avoidance often indicate a specific learning disability rather than ADHD.
Show rationale
The child demonstrates task-specific inattention isolated to reading, while maintaining excellent focus on complex tasks at home. This discrepancy strongly suggests a specific learning disability, such as dyslexia, rather than pervasive ADHD. When a child struggles to process information, they often become frustrated, avoidant, or disruptive, which can mimic ADHD. Referring for psychoeducational testing is the best step to identify the root cause. Diagnosing ADHD or prescribing stimulants is inappropriate without pervasive symptoms. Behavioral modification alone will not address the underlying learning deficit causing the classroom disruption.
Question 9
A 78-year-old patient on post-operative day two develops hyperactive delirium at night. The room is brightly lit, the television is on, and the patient receives frequent vital sign checks. Which intervention is most appropriate?
- A) Prescribe oral melatonin to promote sleep consolidation.
- B) Consolidate nighttime care and dim room lights.✓
- C) Move the patient closer to nurses' station.
- D) Encourage family members to stay awake overnight.
💡 Key Takeaway
Sleep hygiene and environmental modification are critical non-pharmacologic strategies for preventing and managing delirium.
Show rationale
Sleep disruption is a major environmental trigger for delirium in hospitalized older adults. The best non-pharmacologic approach is to cluster nighttime care and reduce environmental stimuli like light and noise. Option A relies on medication rather than addressing the immediate environmental modification needed. Option C increases noise and stimulation, which can worsen hyperactive symptoms. Option D places an undue burden on the family and does not address the environmental factors causing the disruption.
Question 10
An 81-year-old patient with severe lumbar spinal stenosis is initiating low-dose morphine after failing non-opioid therapies. Which concurrent intervention is most appropriate for this patient?
- A) Prescribe a daily proton pump inhibitor
- B) Order a scheduled daily antiemetic medication
- C) Initiate a scheduled stimulant laxative regimen✓
- D) Recommend a daily oral antidiarrheal agent
💡 Key Takeaway
Prophylactic stimulant laxatives must be co-prescribed when initiating opioids in older adults to prevent severe constipation.
Show rationale
Older adults are highly susceptible to opioid-induced constipation, and unlike sedation or nausea, patients do not develop a tolerance to this side effect over time. A stimulant laxative like senna should be prescribed prophylactically whenever opioids are initiated. A proton pump inhibitor is indicated for NSAID gastrointestinal protection, not opioids. Antiemetics might be needed briefly for initial nausea but are not scheduled long-term due to anticholinergic risks. Antidiarrheals would dangerously worsen the severe constipation caused by morphine.
