**Core Concept**
Albuterol sulfate, a short-acting beta-2 adrenergic receptor agonist (SABA), is a bronchodilator used to manage asthma symptoms by relaxing bronchial smooth muscles.

**Why the Correct Answer is Right**
Albuterol works by stimulating beta-2 adrenergic receptors in the bronchial smooth muscles, leading to relaxation and dilation of the airways. This increases airflow and reduces bronchospasm in patients with asthma. The nurse should explain to the patient that albuterol may cause **tachycardia**, a common side effect due to the stimulation of beta-1 and beta-2 adrenergic receptors, leading to increased heart rate.

**Why Each Wrong Option is Incorrect**
**Option A:** Albuterol is not a diuretic, so it does not cause **increased urine production**.
**Option B:** Albuterol does not have a significant effect on **blood pressure**, so it is not a primary concern in this context.
**Option C:** Albuterol is not a sedative, so it does not cause **drowsiness**.

**Clinical Pearl / High-Yield Fact**
Remember that SABAs like albuterol work by relaxing bronchial smooth muscles, but they do not address the underlying inflammation in asthma. This is why inhaled corticosteroids are often used in combination with SABAs for long-term asthma management.

**Correct Answer:** C. Drowsiness.
