Final answer:
The nurse should monitor for tachycardia as a side effect when a client receives their first dose of albuterol (Proventil HFA).
Step-by-step explanation:
The nurse should monitor the client receiving the first dose of albuterol (Proventil HFA) for tachycardia. Albuterol is a bronchodilator used for the treatment of asthma and other conditions with reversible obstructive airway disease. While it is known to be effective in improving airflow, it may cause several side effects, with tachycardia, or an increased heart rate, being one of the more common ones. Other potential side effects may include shakiness, nervousness, or palpitations, but tachycardia is a primary concern especially upon first administration of the medication.
