Rationale: Tiotropium (Spiriva) is not a rescue inhaler but a maintenance medication for COPD. The correct instruction for the nurse to include in the teaching plan is to advise the client to rinse their mouth after using the inhaler. This practice helps prevent dry mouth and throat irritation, common side effects of tiotropium. There are no specific recommendations to take tiotropium on an empty stomach or with a full glass of water.

Rationale: Repaglinide is a rapid-acting oral hypoglycemic that should be taken before meals and withheld if the client does not eat.

Muscle pain may occur as an adverse effect and should be reported to the HCP.

Tremors are a common sign of excessive medication, along with tachycardia and insomnia. Bradycardia, lethargy, and constipation are typical symptoms of hypothyroidism, indicating that the client may require a higher dose of levothyroxine rather than too much.
