Final answer:
Caution should be used in certain patients when giving a beta 2 agonist. Patients with asthma, cardiovascular disease, and diabetes require careful assessment before administration.
Step-by-step explanation:
When giving a beta 2 agonist, caution should be used in patients with certain medical conditions. These conditions include:
- Asthma: Some patients with asthma may have an exaggerated response to beta 2 agonists, which can cause bronchospasm and worsen their condition.
- Cardiovascular disease: Beta 2 agonists can cause an increase in heart rate and blood pressure, which can be problematic in patients with heart disease or high blood pressure.
- Diabetes: Beta 2 agonists can increase blood glucose levels, so caution should be taken in patients with diabetes to prevent hyperglycemia.
It is important for healthcare professionals to carefully evaluate each patient's medical history and assess the risk-benefit ratio before administering a beta 2 agonist.
