Final answer:
Post-administration of epinephrine, a nurse should monitor respiratory symptoms, changes in vital signs, and watch for signs of overstimulation or other adverse effects.
Step-by-step explanation:
After administering epinephrine hydrochloride (Adrenalin) subcutaneously to a pre-school age child with severe asthma symptoms such as dyspnea and wheezing, the nurse should assess the child for several important responses. The administration of epinephrine is expected to constrict blood vessels, which increases blood pressure, and relax smooth muscles in the lungs, easing wheezing and improving breathing. It is also known to modulate heart rate and reduce swelling potentially obstructing airways.
The nurse should monitor the child for an improvement in respiratory symptoms, such as reduced wheezing and eased breathing. Additionally, it is critical to observe for changes in vital signs, especially blood pressure and heart rate, ensuring that they return to normal ranges. Due to the potential for epinephrine to cause side effects, the nurse should also watch for signs of overstimulation such as palpitations, tremors, or anxiety, and assess for any other adverse reactions to the medication.
