A nurse is caring for a client who states he recently purchased lavender oil to use when he gets the flu.
The nurse should recognize which of the following findings as a potential contraindication for using lavender?

Choice A rationale:

Weight gain is a common side effect of many antipsychotic medications, including haloperidol. While it is important to monitor for this adverse effect, it is not specifically related to the extrapyramidal symptoms associated with haloperidol use.

Choice B rationale:

Dry mouth is a common anticholinergic side effect of antipsychotic medications like haloperidol. Although it is important to monitor for this adverse effect, it is not specifically related to the extrapyramidal symptoms, such as parkinsonism, associated with haloperidol use.

Choice C rationale:

This is the correct answer. Shuffling gait, or parkinsonism, is an extrapyramidal symptom associated with the use of antipsychotic medications like haloperidol. It is a movement disorder characterized by a shuffling walk, rigidity, and tremors. Recognizing and reporting this symptom promptly is crucial, as it may indicate the development of a serious neurological condition called tardive dyskinesia.

Choice D rationale:

Sedation is a common side effect of haloperidol and other antipsychotic medications. While it is important to monitor for sedation, it is not specifically related to the extrapyramidal symptoms associated with haloperidol use, as described in choice C.

Choice A rationale:

Metallic taste in mouth. Metallic taste in the mouth is a common side effect of many medications, including sertraline. It occurs due to the medication's effect on taste receptors. Patients should be informed about this side effect, but it is not a serious adverse effect that requires immediate medical attention.

Choice B rationale:

Increased urinary frequency. Increased urinary frequency is not a commonly reported side effect of sertraline. While some individuals may experience changes in urination patterns, it is not a significant adverse effect associated with this medication.

Choice C rationale:

Dry cough. Dry cough is not a known side effect of sertraline. Cough can occur due to various reasons, such as allergies, respiratory infections, or other medications, but it is not directly caused by sertraline.

Choice D rationale:

Excessive sweating. Excessive sweating, also known as hyperhidrosis, is a potential adverse effect of sertraline. It can be bothersome for some individuals and may impact their quality of life. Patients should be aware of this side effect and report it to their healthcare provider if it becomes bothersome or persistent.
