After receiving a nebulizer treatment with a beta agonist, the patient complains of feeling slightly nervous and wonders if her asthma is getting worse. What is the nurse's best response?

A. "We will hold the treatment for 24 hours.": Holding a beta-agonist treatment for an entire day is unnecessary and could compromise asthma control. Mild nervousness and tremors are known side effects, and withholding the medication without assessment could place the client at risk for worsening bronchospasm or hypoxia. B. "The next scheduled nebulizer treatment will be skipped.": Skipping a scheduled dose without evaluating the client’s response or severity of symptoms could lead to inadequate bronchodilation. Beta-agonist therapy should continue as prescribed unless contraindicated by severe adverse effects. C. "I will notify the physician about this adverse effect.": While notifying the provider may be appropriate for severe or persistent reactions, mild nervousness and palpitations are common transient side effects. Immediate assessment of vital signs and symptom severity is the priority to determine whether the treatment can safely continue. D. "This is an expected adverse effect. Let me assess your pulse.": Beta-agonists stimulate beta-2 and, to a lesser extent, beta-1 adrenergic receptors, causing common side effects such as mild nervousness, tremors, and tachycardia. Assessing the pulse and respiratory status confirms the client’s safety and helps differentiate expected pharmacologic effects from other complications.
