Mastering Psychiatry for FNP Boards: Your High-Yield Guide

Hey future FNPs! Feeling a little overwhelmed by the sheer volume of information for your board exams? Psychiatry is often a section that gives students pause, but it doesn't have to. While you won't be expected to manage complex psychiatric cases like a PMHNP, the boards will test your ability to screen, diagnose common conditions, initiate first-line treatments, and recognize when to refer. This high-yield guide will cut through the noise and focus on what you absolutely need to know to confidently tackle psychiatry questions on your AANP and ANCC exams.

Common Psychiatric Disorders: What to Prioritize

When it comes to the boards, focus on the most prevalent mental health conditions you'll encounter in primary care. These include depression, anxiety disorders, bipolar disorder, schizophrenia, and ADHD.

Depression

Depression is a cornerstone of primary care mental health. You must be proficient in screening, diagnosis, and initial management.

Screening: The PHQ-9 is your go-to tool. Remember that a score of 5-9 indicates mild depression, 10-14 moderate, 15-19 moderately severe, and 20-27 severe. The PHQ-2 is often used as an initial screen. The USPSTF recommends screening all adults for depression, including pregnant and postpartum women.
Diagnosis: Based on DSM-5 criteria, including depressed mood or anhedonia for at least two weeks, plus other symptoms like changes in sleep, appetite, energy, concentration, self-worth, or psychomotor activity.
First-line Treatment: SSRIs or SNRIs are typically the first-line pharmacological agents, often combined with cognitive behavioral therapy (CBT).

Anxiety Disorders

Generalized Anxiety Disorder (GAD), Panic Disorder, and PTSD are frequently tested.

GAD: Characterized by excessive, uncontrollable worry about multiple domains for at least 6 months, associated with 3 or more of the following: restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbance.
Screening: The GAD-7 is the recommended screening tool.
First-line Treatment: Similar to depression, SSRIs or SNRIs are first-line, often with CBT. Buspirone is an alternative non-benzodiazepine anxiolytic. Benzodiazepines are effective short-term but are not first-line due to dependence risk.

Bipolar Disorder

Boards test your ability to recognize bipolar disorder and understand the pharmacology of mood stabilizers.

Key Features: Episodes of mania (or hypomania) and depression. A manic episode involves an elevated or irritable mood lasting at least 1 week (or any duration if hospitalization is required), with 3 or more of: grandiosity, decreased need for sleep, pressured speech, racing thoughts, distractibility, increased goal-directed activity, and impulsive behavior. Hypomania is a less severe form lasting at least 4 days without marked impairment.
Screening: The Mood Disorder Questionnaire (MDQ) is a widely used screening tool.
Treatment: Mood stabilizers such as lithium and valproate are mainstays.

Schizophrenia

Focus on recognizing positive and negative symptoms and the general treatment approach.

Symptoms: Characterized by positive symptoms (hallucinations, delusions, disorganized speech and behavior) and negative symptoms (flat affect, alogia, avolition, anhedonia, asociality). The boards often test the distinction because these symptom categories respond differently to treatment.
Treatment: Antipsychotics are the mainstay. First-generation (typical) antipsychotics are effective for positive symptoms but carry a higher risk of extrapyramidal side effects (EPS) and tardive dyskinesia. Atypical antipsychotics are generally preferred.

ADHD

Attention-Deficit/Hyperactivity Disorder is a common neurodevelopmental disorder.

Diagnosis: Requires symptoms of inattention and/or hyperactivity-impulsivity present in multiple settings, causing impairment, and worsening from a baseline. Screening tools like the Vanderbilt scales can be helpful.
Treatment: Often involves a combination of pharmacotherapy (stimulants, non-stimulants) and behavioral interventions.

Essential Pharmacology & Clinical Pearls

Psychopharmacology is a critical component of psychiatric management for many patients.

Clinical Pearl #1: Serotonin Syndrome

Know the triad: altered mental status, autonomic instability (hyperthermia, tachycardia, diaphoresis), and neuromuscular abnormalities (clonus, hyperreflexia, tremor). It's most commonly caused by combining an SSRI with another serotonergic agent (e.g., MAOIs, tramadol, triptans, St. John's Wort). Treatment involves discontinuing the offending agents and supportive care.

Clinical Pearl #2: Extrapyramidal Symptoms (EPS)

These are common side effects of first-generation antipsychotics. Be able to identify acute dystonia, akathisia, parkinsonism, and tardive dyskinesia (TD). Understanding these helps you choose appropriate medications and manage side effects.

Clinical Pearl #3: Lithium Toxicity

Lithium is a narrow therapeutic index drug. Monitor levels closely. Symptoms of toxicity can include nausea, vomiting, diarrhea, tremor, ataxia, slurred speech, and seizures. Ensure patients are well-hydrated and avoid NSAIDs, thiazide diuretics, and ACE inhibitors, which can increase lithium levels.

When to Refer: Recognizing the Limits of Primary Care

FNP boards will test your judgment on when a patient needs a higher level of care.

Active Suicidal Ideation with Plan and Intent: This is an emergency. The correct response is emergency psychiatric evaluation, not outpatient referral.
Psychosis: While you might initiate treatment for schizophrenia, complex or first-episode psychosis often warrants referral to a psychiatrist.
Complex Bipolar Management: While you can initiate mood stabilizers, ongoing management of complex bipolar disorder, especially with frequent mood episodes or psychotic features, often benefits from psychiatric co-management.
Treatment-Resistant Depression/Anxiety: If first-line treatments are ineffective after adequate trials, referral to a specialist is appropriate.
Eating Disorders: These often require a multidisciplinary team approach, including psychiatric, medical, and nutritional support.
Personality Disorders: While you'll encounter these in primary care, their complex and chronic nature often necessitates specialized psychotherapy and psychiatric management.

Non-Pharmacological Interventions

Remember that medication is often just one piece of the puzzle.

Psychotherapy: Cognitive Behavioral Therapy (CBT) and other forms of talk therapy are crucial for many conditions, including depression, anxiety, and ADHD.
Lifestyle Modifications: Exercise, healthy diet, adequate sleep, stress management, and strong social support systems are vital for mental well-being.
Patient Education: Empowering patients with knowledge about their condition and treatment plan improves adherence and outcomes.
