Answer to Question 1

ANS: A
When beta blockers are used for anginal pain, the dosing goal is to reduce the resting heart rate to 50 to 60 beats per minute. Because this heart rate is a desired effect, there is no need to withhold the dose or notify the provider. The dosage does not need to be lowered, because a heart rate of 55 beats per minute is a desired effect. There is no indication of a need to change medications for this patient.

Answer to Question 2

ANS: C
An initial dose of sublingual nitroglycerin is taken, and if the chest pain persists, as in this case, the patient should take another dose in 5 minutes. Transdermal delivery systems are not useful for terminating an ongoing attack. Dosing at 10-minute intervals is incorrect. If the patient fails to respond or if the pain intensifies, intravenous nitroglycerin may be indicated.
