A 60-year-old man was admitted for cholecystitis that resulted in a cholecystectomy. On his third day of hospitalization, he begins to sweat profusely, tremble, and has a blood pressure of 160/100. Based on these findings, what focused assessment should the nurse complete?

A. Monitor for signs of seizure activity: Seizure activity is not directly related to the condition described.
B. Increase the IV rate and monitor for burn shock: Increasing the IV rate could exacerbate fluid overload; burn shock is more of a concern in the initial hours post-burn.
C. Raise the foot of the bed and apply blankets. This is not relevant to addressing the issue of large urine output.
D. Assess for signs of fluid overload: After the initial fluid resuscitation phase, large urine output may indicate that fluid is being mobilized from the tissues back into the vascular system, potentially leading to fluid overload.

A. Bipolar disorder: The described behavior of extreme mood swings (elevated mood followed by significant depression) is characteristic of bipolar disorder.

B. Dysthymic disorder: Dysthymic disorder (now known as persistent depressive disorder) involves a chronic state of depression but does not typically feature such pronounced mood swings.

C. Hypomanic episode: A hypomanic episode would involve elevated mood but would not usually be followed by the severe depressive episode described.

D. Unipolar depression: Unipolar depression is characterized by a persistent low mood rather than the dramatic shifts described.
