In which scenario is it most appropriate to administer medication first?

Administering medication first in a scenario where a client is experiencing an asthma attack is critical due to the immediate potential for respiratory distress. In an asthma attack, a patient's airways become constricted, making it difficult to breathe and leading to hypoxia. The priority in such a situation is to ensure the patient can breathe adequately; therefore, administering bronchodilators or other medications that can relieve the attack takes precedence.

While the other scenarios also involve patient care, they do not present the same level of acute risk. A client requesting a snack is indicating that they are stable regarding nutrition, and they are not in immediate danger. A client with low blood pressure reporting dizziness may require intervention, but addressing the asthma attack takes precedence due to the higher likelihood of life-threatening consequences. The same goes for a client requesting pain medication while stable, as their condition does not necessitate immediate action in comparison to the respiratory emergency posed by an asthma attack. Thus, the urgency of the medical need and the potential consequences align to make the asthma patient the top priority for medication administration.
