A nurse is reviewing the laboratory results of an adolescent female client and notes a WBC count of 16,000/mm² with increased immature neutrophils (bands) and normal monocytes. Which of the following is the appropriate analysis of the results?
An acute infectious process.
A resolving inflammatory process.
Allergic reaction.
Neutropenia.
The Correct Answer is A
Choice A rationale:
An increased WBC count with increased bands (immature neutrophils) indicates an acute infectious process. Normal range for WBC is 4,500-11,000/mm².
Choice B rationale:
A resolving inflammatory process would typically show a decreasing WBC count.
Choice C rationale:
An allergic reaction would typically show an increase in eosinophils, not neutrophils.
Choice D rationale:
Neutropenia is a decrease in neutrophils, not an increase.

Explanation
-
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.
