A health teaching plan for a patient taking lithium should include instructions to
drink twice the usual dally amount of fluid.
double the lithium dose if diarrhea or vomiting occurs.
maintain normal salt and fluids in the diet.
avoid eating aged cheese, processed meats, and red wine.
The Correct Answer is C
A. Patients do not need to double fluid intake, just maintain adequate hydration (2–3 L/day). Drinking twice the usual amount could lead to fluid overload or dilute sodium balance.
B. Lithium should never be doubled. In fact, vomiting and diarrhea increase risk of lithium toxicity, so the provider must be notified instead.
C. Lithium excretion is closely tied to sodium and fluid balance. A stable diet with normal salt and adequate fluid intake helps prevent fluctuations in lithium levels and reduces risk of toxicity.
D. Avoiding aged cheese, processed meats, and red wine is teaching for MAOI therapy (to prevent hypertensive crisis due to tyramine), not for lithium.

Explanation
A. Thyroid function tests are not routinely required for valproate therapy; this applies more to lithium therapy.
B. A pretreatment EEG is not necessary before starting valproate; it is used primarily for seizure evaluation.
C. Valproate can cause hepatotoxicity, so monitoring liver function tests (LFTs) before and during therapy is essential for safety.
D. High serum sodium levels are not related to valproate toxicity; this concern is associated with lithium therapy, not valproate.
Correct Answer is D
Explanation
A. Extreme anxiety with brief dazed periods describes depersonalization or dissociative episodes, but not a fugue, because identity and travel are not involved.
B. Feeling like the body is unreal or shrinking is indicative of depersonalization-derealization disorder, not dissociative fugue.
C. Unfamiliar clothes and blackouts without alcohol may suggest dissociative identity disorder, as multiple identities or personality states are involved.
D. Dissociative fugue involves sudden, unexpected travel away from one’s home or workplace, inability to recall the past, and confusion about personal identity or assumption of a new identity. The scenario describes disappearance, travel, and memory loss consistent with dissociative fugue.
