A nurse is caring for a 1-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The guardian asks, "What are the indication that my baby needs an IV?" Which of the following responses should the nurse make?

Rationale for correct choices:

• Mania: The client exhibits classic signs of mania, including decreased need for sleep, excessive energy, impulsive spending, grandiosity, pressured and disorganized speech, and poor self-care. These behaviors reflect a manic episode, often seen in bipolar disorder, which requires careful monitoring and intervention.
• Euphoric mood: The client demonstrates an abnormally elevated and joyous mood, along with inflated self-confidence and excessive sociability. This euphoric mood is a hallmark feature of mania and differentiates it from other psychiatric conditions such as depression or delirium.

Rationale for incorrect choices:

• Major depressive disorder: This disorder presents with persistent low mood, anhedonia, and decreased energy. The client displays the opposite symptoms, including hyperactivity, elevated mood, and impulsivity, making depression an unlikely diagnosis.
• Delirium: Delirium is characterized by an acute change in attention, confusion, and disorientation, often fluctuating throughout the day. While the client is disoriented to place, the presence of sustained elevated mood and hyperactivity supports mania rather than delirium.
• Panic disorder: Panic disorder involves sudden, intense episodes of fear with physical symptoms like palpitations, shortness of breath, and sweating. The client’s presentation is chronic and includes mood elevation and impulsive behaviors, which are inconsistent with panic disorder.
• Catatonia: Catatonia involves motor immobility, mutism, or extreme negativism. The client is highly active, with constant movement and pressured speech, which is the opposite of catatonic presentation.
• Anhedonia: Anhedonia refers to the inability to experience pleasure and is a symptom of depression. The client shows excessive pleasure-seeking behaviors, including socializing and impulsive spending, making anhedonia inconsistent with the current presentation.
• Hypervigilance: Hypervigilance involves heightened alertness and exaggerated startle response, often seen in anxiety or PTSD. The client’s primary features are elevated mood and impulsive behavior rather than persistent vigilance.
• Magical thinking: Magical thinking involves believing that one’s thoughts or actions can influence unrelated events. While the client reports hallucinations, there is no evidence of magical thinking as the hallucinations do not involve causative beliefs.
• Alogia: Alogia is a reduction in speech output, typically seen in schizophrenia or severe depression. The client’s speech is pressured, loud, and disorganized, which is opposite to alogia.

A. Atrial fibrillation: This dysrhythmia is characterized by an irregularly irregular rhythm with absent or unidentifiable P waves, not a prolonged constant P-R interval.

B. Premature atrial complexes: PACs involve early P waves that may have a normal or slightly different P-R interval, but they do not cause a consistently prolonged P-R interval across all beats.

C. First-degree atrioventricular block: A constant P-R interval greater than 0.20 seconds indicates a first-degree AV block. The atrial impulses are delayed at the AV node, but all impulses are conducted to the ventricles, producing a regular rhythm with prolonged P-R intervals.

D. Complete heart block: In complete heart block (third-degree AV block), there is no relationship between P waves and QRS complexes. The P-R interval is variable, unlike the constant prolongation seen in first-degree AV block.
