Answer and Explanation

The Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"B"},"E":{"answers":"B"}}

  • Vision (Blurred)

    • Interpretation: Potential worsening condition
    • Rationale: Blurred vision can be a sign of lithium toxicity. Despite the lithium level improving, this symptom indicates that neurotoxicity may still be present.

  • Lithium Level (1.2 mEq/L)

    • Interpretation: Potential improvement
    • Rationale: The lithium level has decreased from 1.8 mEq/L (toxic) to 1.2 mEq/L, which is within the therapeutic range (0.6-1.2 mEq/L). This indicates that treatment to lower lithium toxicity is effective.

  • Urine Output (40 mL/hr)

    • Interpretation: Potential improvement
    • Rationale: A urine output of 40 mL/hr is within the acceptable range (normal is greater than 30 mL/hr), suggesting that kidney function is adequate and not compromised by lithium toxicity.

  • Mucous Membranes (Pale, Dry)

    • Interpretation: Potential worsening condition
    • Rationale: Pale, dry mucous membranes suggest dehydration, which can increase the risk of lithium toxicity and negatively affect overall health.

  • Vital Signs (BP 88/50 mm Hg, Pulse 96/min)

    • Interpretation: Potential worsening condition
    • Rationale: The drop in blood pressure from 130/84 mm Hg to 88/50 mm Hg indicates hypotension. This could be related to dehydration or lithium toxicity, and it requires follow-up as the condition is deteriorating.
