A nurse is educating parents on the signs of suicidal ideation in adolescents. Which sign should the parents be most vigilant about due to its direct association with suicide risk?

A. Predominantly aggressive outbursts without other mood alterations can complicate the diagnosis of bipolar disorder because aggression alone is nonspecific. While irritability or anger can occur in bipolar disorder, isolated aggressive behavior may overlap with other conditions such as oppositional defiant disorder (ODD), conduct disorder, or ADHD, making it difficult to distinguish bipolar disorder based solely on aggression. Accurate diagnosis requires clear evidence of mood episodes (mania, hypomania, or depression) rather than isolated behavioral outbursts.

B. Difficulty with academic focus and performance is common in adolescents with bipolar disorder due to attention difficulties, mood fluctuations, or comorbid ADHD. While it is a symptom, it is nonspecific and would not in itself complicate diagnosis as much as isolated aggression.

C. Fluctuations between feelings of excitement and apathy are consistent with bipolar disorder, reflecting alternating manic/hypomanic and depressive states. This pattern supports the diagnosis rather than complicates it.

D. Consistent behavior of detachment from peers may indicate depression or social anxiety but is less likely to obscure the diagnosis of bipolar disorder if clear mood episodes are present. It is more of a supportive feature than a complicating factor.

A. Hallucinations and delusions are not characteristic of postpartum blues; they are signs of postpartum psychosis, which is a psychiatric emergency requiring immediate intervention.

B. Crying easily and frequently, resolving within two weeks, is the hallmark symptom of postpartum blues. It typically begins within the first few days after delivery and resolves spontaneously without medical intervention. Other common symptoms include mood swings, irritability, and anxiety.

C. A complete lack of interest in the newborn suggests postpartum depression, a more serious condition that requires intervention and does not resolve spontaneously within two weeks.

D. Persistent sadness lasting more than two weeks is indicative of postpartum depression, not postpartum blues. Postpartum blues are self-limiting and short-lived, whereas postpartum depression requires active treatment and support.
