A patient is prescribed verapamil for supraventricular tachycardia. Which finding requires the nurse to withhold the dose and notify the prescriber?
Correct answer: A. Apical pulse of 52 beats per minute
- A. Apical pulse of 52 beats per minute
- B. Blood pressure of 138 over 84 millimetres of mercury
- C. Respiratory rate of 18 breaths per minute
- D. Mild flushing after the previous dose
Explanation
Verapamil slows atrioventricular conduction and can produce significant bradycardia, so an apical pulse of 52 beats per minute requires review before administration. Mild flushing may occur, while the stated blood pressure and respiratory rate are not by themselves reasons to withhold it.
