Margaret, a 68-year-old widow, is brought to the emergency department by her sister-in-law. Margaret has a history of bipolar disorder and has been maintained on medication for many years. Her sister-in-law reports that Margaret quit taking her medication a few months ago, thinking she did not need it anymore. She is agitated, pacing, demanding, and speaking very loudly. Her sister-in-law reports that Margaret eats very little, is losing weight, and almost never sleeps. “I am afraid she is going to just collapse!” Margaret is admitted to the psychiatric unit. The priority nursing diagnosis for Margaret is:
Imbalanced nutrition: less than body requirements related to not eating
Risk for injury related to hyperactivity
Disturbed sleep pattern related to agitation
Ineffective coping related to denial of depression
The Correct Answer is B
Manic episodes in bipolar I disorder are characterized by elevated mood, hyperactivity, and impaired judgment, often resulting in risk-taking behaviors and physical exhaustion. Clients may exhibit pressured speech, pacing, and agitation, which significantly increase the risk of injury due to falls, collisions, or physical depletion. The priority in acute mania is to ensure safety, as the combination of psychomotor agitation and poor insight can lead to accidental harm or collapse from exhaustion. Nutritional and sleep deficits are important but secondary to immediate physical risk.
Rationale for correct answer
2. Margaret’s extreme hyperactivity and agitation place her at high risk for physical harm. Her inability to rest, combined with poor nutritional intake, increases the likelihood of injury from collapse, falls, or overexertion.
Rationale for incorrect answers
1. While Margaret’s poor intake is concerning, nutrition is not the most immediate threat. The physical consequences of hyperactivity, such as collapse or injury, take precedence in acute care.
3. Sleep disturbance is a hallmark of mania, but agitation and hyperactivity pose more immediate safety risks. Sleep can be addressed once Margaret is stabilized and safe.
4. Denial of illness is common in bipolar disorder, but coping strategies are not the priority during acute manic episodes. Immediate physiological safety concerns override psychosocial considerations.
Take Home Points
- In acute mania, physical safety risks due to hyperactivity and exhaustion are the top nursing priority.
- Nutritional and sleep deficits are important but secondary to injury prevention during manic episodes.
- Bipolar clients often lack insight into their condition, requiring structured interventions to ensure safety.
- Nursing diagnoses must prioritize physiological needs first, especially when behaviors threaten immediate harm.

Correct Answer is A
Explanation
Bipolar I disorder is a chronic psychiatric condition marked by alternating episodes of mania and depression. During manic phases, clients exhibit elevated mood, hyperactivity, grandiosity, and poor impulse control. These episodes often impair judgment and increase risk-taking behaviors, including aggression, self-harm, and harm to others. The manic state may also include psychotic features such as hallucinations or delusions, but the most immediate concern is safety—especially when disinhibition and impulsivity escalate to violent behavior.
Rationale for correct answer
1. During acute mania, impulsivity and poor judgment heighten the risk of aggressive outbursts toward others. The client may misinterpret interactions or act on grandiose beliefs, making violence a priority concern for nursing safety interventions.
Rationale for incorrect answers
2. Although hallucinations may occur in manic episodes, they are not the most immediate threat unless they directly provoke harmful behavior. The priority is safety, not perceptual disturbances.
3. Manic clients are typically hyper-social and intrusive, not withdrawn. Isolation is more characteristic of depressive phases, making this diagnosis less relevant during acute mania.
4. Feelings of guilt and low self-esteem are more prominent in depressive episodes. During mania, clients often display inflated self-worth and lack insight into inappropriate behaviors.
Take Home Points
- In acute mania, safety risks due to impulsivity and aggression take precedence over other psychosocial concerns.
- Bipolar I disorder includes manic episodes that may escalate to psychosis or violence, requiring close monitoring.
- Differentiating manic symptoms from depressive or psychotic features is essential for accurate nursing diagnosis.
- Nursing priorities shift with phase of illness—mania demands safety-focused interventions, while depression may focus on mood and cognition.
Correct Answer is B
Explanation
Aripiprazole is a second-generation antipsychotic used in the management of acute mania in bipolar I disorder. It acts as a partial agonist at dopamine D2 and serotonin 5-HT1A receptors, and antagonist at 5-HT2A receptors. Its pharmacologic profile allows it to stabilize mood and reduce excitability without excessive sedation. When administered intramuscularly in acute settings, it rapidly targets agitation and hyperactivity, making it suitable for de-escalation. Unlike sedatives, its goal is behavioral control rather than sedation, and it does not immediately equalize mood swings.
Rationale for correct answer
2. Aripiprazole’s primary effect in acute mania is reducing excitability and agitation. Its dopaminergic modulation calms hyperactive behavior without causing oversedation, allowing for safer interaction and stabilization.
Rationale for incorrect answers
1. Sedation is not the therapeutic goal of aripiprazole. While some calming may occur, excessive sedation suggests overmedication or use of a different pharmacologic class like benzodiazepines.
3. Although aripiprazole can reduce psychotic symptoms over time, its immediate IM use in acute mania targets agitation and excitability first. Psychotic symptom relief is not the primary indicator of short-term effectiveness.
4. Mood stabilization is a long-term goal in bipolar management. Acute IM administration does not equalize mood swings immediately; it primarily addresses behavioral dysregulation.
Take Home Points
- Aripiprazole IM is used for rapid control of agitation and excitability in acute manic episodes.
- Sedation is not the intended outcome; behavioral calming without oversedation is preferred.
- Psychotic symptom relief and mood stabilization are longer-term therapeutic goals.
- In acute psychiatric emergencies, medication effectiveness is judged by reduction in dangerous or disruptive behaviors.
