The nurse is caring for a client who is taking a bronchodilator. In what disease process should bronchodilators be used cautiously?
liver failure
renal failure
respiratory failure
heart failure
The Correct Answer is D
A. Liver failure does not have a direct contraindication with bronchodilators, though careful monitoring is needed.
B. Renal failure is not a direct contraindication for bronchodilator use; however, kidney function can affect drug metabolism and clearance.
C. Respiratory failure may necessitate bronchodilator therapy rather than caution, especially in conditions like COPD or asthma where bronchodilators are crucial for management.
D. Heart failure requires caution with bronchodilators because they can lead to increased heart rate and blood pressure, potentially exacerbating heart failure symptoms or leading to arrhythmias.
