Correct answer: B — Query the combination because verapamil with beta-blocker increases bradycardia and heart block risk
Beta-blockers combined with verapamil can cause significant bradycardia, hypotension and AV block. The patient's baseline pulse is already relatively low, making the risk clinically important. The low starting dose of bisoprolol does not remove the need to query the combination. Lipid monitoring is not relevant to this immediate safety issue.
