A charge nurse observes smoke coming from a trash receptacle in the unit's waiting room.
Which of the following actions should the nurse take first?

• A is incorrect because diarrhea is not an adverse effect of clonidine, but rather a symptom of other conditions such as infection, inflammation, or food intolerance.
• B is correct because dry mouth is a common adverse effect of clonidine, which is an alpha-2 adrenergic agonist that reduces sympathetic nervous system activity.
• C is incorrect because photophobia, or sensitivity to light, is not an adverse effect of clonidine, but rather a symptom of other conditions such as migraine, eye injury, or infection.
• D is incorrect because bruising, or bleeding under the skin, is not an adverse effect of clonidine, but rather a symptom of other conditions such as coagulation disorders, vitamin deficiency, or trauma.

- A is incorrect because massaging bony prominences on the client's left side can increase the risk of skin breakdown and pressure ulcers. The nurse should avoid applying pressure to areas with impaired circulation or sensation.

- B is correct because supporting the client's left arm on a pillow while sitting can prevent edema, contractures, and nerve damage. The nurse should also encourage the client to perform active and passive range of motion exercises on their left arm.

- C is incorrect because positioning the bedside table on the client's left side can discourage the client from using their right side, which can lead to neglect and learned nonuse. The nurse should position the bedside table on the client's right side and encourage them to reach for items with their right hand.

- D is incorrect because placing the client's cane on their left side while ambulating can cause instability and falls. The nurse should place the cane on the client's right side and instruct them to move their left leg and cane together, followed by their right leg.
