Which condition would alert the nurse to use beta adrenergic blockers cautiously?

Beta adrenergic blockers should be used cautiously in patients with Asthma or chronic obstructive pulmonary disease (COPD), as these medications can cause bronchoconstriction due to their non-selective properties. Additionally, caution is warranted in patients with bradycardia, heart block, or severe peripheral vascular disease, as beta blockers can exacerbate these conditions. It's essential for the nurse to assess the patient's respiratory and cardiovascular status before administering these medications.
