A nurse manager is teaching a group of nurses about bacterial meningitis. Which of the following information should the nurse include in the teaching?

A. Severe hypertension: Cushing’s triad is characterized by increased systolic blood pressure with widening pulse pressure as a compensatory response to maintain cerebral perfusion during increased intracranial pressure. Severe hypertension is a hallmark finding.

B. Narrowed pulse pressure: In Cushing’s triad, the pulse pressure is typically widened, not narrowed, due to elevated systolic pressure and relatively lower diastolic pressure. Narrowed pulse pressure does not reflect the classic pattern associated with increased ICP.

C. Diastolic murmur: A diastolic murmur is a cardiac finding unrelated to increased intracranial pressure and is not a component of Cushing’s triad. It does not provide information about cerebral perfusion or ICP.

D. Increased heart rate: Cushing’s triad involves bradycardia rather than tachycardia, as part of the body’s compensatory response to elevated ICP. An increased heart rate is inconsistent with this classic presentation.

Rationale for correct choices

• Mania: The client exhibits classic signs of mania, including elevated mood, excessive energy, decreased need for sleep, impulsive behavior such as excessive spending, and pressured, disorganized speech. These behaviors are consistent with a manic episode rather than delirium, catatonia, major depressive disorder, or panic disorder.

• Euphoric mood: The client demonstrates an overly joyous and elevated sense of self-confidence, which is characteristic of euphoric mood during a manic episode. Euphoric mood contributes to impulsive behaviors, distractibility, and poor judgment. This finding aligns with the manic episode and helps distinguish mania from other psychiatric conditions that primarily involve negative mood states or anxiety.

Rationale for incorrect choices

• Delirium: Although the client is disoriented to place and exhibits poor concentration, delirium typically develops acutely and fluctuates, often secondary to a medical condition or substance use. The client’s sustained elevated mood, impulsive behavior, and pressured speech are not consistent with delirium.

• Panic disorder: Panic disorder involves sudden episodes of intense fear, palpitations, and autonomic hyperactivity, which are not reported in this client. The client’s persistent elevated mood, lack of fear-driven episodes, and impulsive behaviors do not align with panic disorder symptoms.

• Catatonia: Catatonia is characterized by motor immobility, stupor, mutism, or rigidity, which contrasts sharply with the client’s constant movement, hyperactivity, and pressured speech. The client demonstrates goal-directed and excessive activity rather than the motor inhibition seen in catatonia.

• Major depressive disorder: Major depressive disorder involves persistent low mood, anhedonia, and lack of energy, which is the opposite of the client’s elevated, euphoric mood and hyperactivity. The client’s impulsivity and pressured speech indicate a manic state rather than depression. Depressive symptoms are not evident in the current presentation.

• Magical thinking: Although magical thinking can occur in some psychiatric conditions, the client’s primary feature is euphoric mood and goal-directed hyperactivity. There is no evidence of superstitious beliefs or illogical thought processes driving behavior.

• Alogia: Alogia refers to poverty of speech or reduced verbal output, which is inconsistent with the client’s pressured and loud speech. The client demonstrates excessive verbal output, indicating elevated energy rather than speech poverty.

• Anhedonia: Anhedonia, or lack of pleasure, is a symptom of depression, which is absent here. The client’s enjoyment of activities, desire to host parties, and euphoric mood contradict the presence of anhedonia.

• Hypervigilance: Hypervigilance involves excessive alertness and scanning for threats, often seen in anxiety or PTSD. While the client reports seeing hallucinations, these perceptual disturbances are more consistent with psychosis, not hypervigilance. The primary finding supporting mania is euphoric mood rather than anxiety-driven alertness.
