The lithium level is too low
The lithium level is therapeutic
Lithium is not usually monitored with blood levels
The lithium level is too high
The Correct Answer is B
A. A lithium level of 0.9 mEq/L falls within the therapeutic range for lithium, so it is not too low.
B. A lithium level of 0.9 mEq/L is within the therapeutic range for lithium maintenance therapy, which typically ranges from 0.6 to 1.2 mEq/L. Therefore, it is considered therapeutic.

B. Intractable hiccups: While hiccups can occur as a side effect of some medications, they are not a commonly reported adverse effect of haloperidol.
C. Excessive salivation: Excessive salivation is not a typical adverse effect of haloperidol.
D. Extrapyramidal symptoms: Haloperidol, as a first-generation antipsychotic, is known to cause extrapyramidal symptoms such as dystonia, akathisia, parkinsonism, and tardive dyskinesia. Monitoring for these adverse effects is essential during treatment with haloperidol.
Correct Answer is D
Explanation
A. Do slow position changes to avoid falls from lowering blood pressure: This is not the priority teaching point for an anticholinergic medication. While some anticholinergics can cause orthostatic hypotension, the risk of urinary retention is a more significant concern.
B. If you feel short of breath, use a rescue inhaler: This instruction is unrelated to the use of anticholinergic medication and may be more relevant for patients with emphysema.
C. "If possible, try to avoid rooms that are cold.": Avoiding cold rooms is not directly related to the use of anticholinergic medication. The priority teaching point should address potential adverse effects specific to the medication.
D. "Make sure to seek care immediately if you're not able to urinate.": Anticholinergic medications can exacerbate urinary retention, particularly in older adults with benign prostatic hyperplasia. It's crucial for the patient to understand the importance of seeking medical attention if they experience difficulty urinating.
