For beta-adrenergic blocker therapy, common holding parameters include which of the following?

• A. Apical pulse <60
• B. Systolic blood pressure <90
• C. Both Apical Pulse <60 and Systolic BP <90
• D. Diastolic BP <60

Answer: (C)

Beta-adrenergic blockers lower heart rate and decrease blood pressure, so when either control parameter falls too far, continuing the medication can worsen perfusion. The safest holding thresholds commonly used are an apical pulse below 60 beats per minute and a systolic blood pressure below 90 mmHg. If either occurs, holding the drug helps prevent inadequate cardiac output and organ perfusion.

Diastolic pressure by itself isn’t typically used as the trigger to stop beta-blockade, since systolic pressure more directly reflects cardiac output and perfusion during activity. The combination of bradycardia (HR <60) and hypotension (SBP <90) represents the standard safety checks, so the option that includes both is the best fit.
