Bipolar Phases: Mania vs Depression — Presentation, Safety Priorities, Medication Differences
Both bipolar phases are dangerous, but for opposite reasons. Picking the wrong safety priority — limiting impulsivity when you should be screening for suicide, or vice versa — costs the NCLEX question and, clinically, could cost a life. The transition between phases is the deadliest window.

Side-by-side2 compared
Dimension
Manic Phase
Depressive Phase
Phase definition
- Elevated/irritable mood ≥ 1 week
- Euphoric, grandiose, labile
- Depressed mood ≥ 2 weeks
- Flat, hopeless, tearful
Signs & symptoms
- ★Pressured speech, flight of ideas
- ↓ sleep, not tired; grandiosity, hyperactive
- Psychomotor retardation; slow soft speech
- Hypersomnia/insomnia, fatigue; withdrawal
Nursing priorities
- Decrease stimulation; firm consistent limits
- Finger foods + monitor I&O (too distracted)
- Structured routine; encourage gradual activity
- Sit at meals; avoid isolation
Treatment & meds
- Lithium (0.6–1.2 mEq/L); valproate acute
- Watch lithium toxicity > 1.5
- Lithium or lamotrigine maintenance
- ★Antidepressant ONLY with mood stabilizer
Patient teaching
- Adhere to mood stabilizer; regular levels
- Lithium: consistent Na & fluid intake
- Take meds even when feeling better
- Antidepressant takes 2–4 wk; report worsening
Safety — escalate
- Injury from impulsivity; exhaustion, dehydration
- ★Suicide risk highest as energy returns
Complications
- Financial/legal/relationship damage
- Suicide; chronic disability

Clinical Pearl
Mania kills through impulsivity — decrease stimulation. Depression kills through suicide — assess when energy returns first.
