A nurse is caring for a client who has variant angina and is prescribed verapamil. Which of the following are expected outcomes of this medication? (Select all that apply.)
Verapamil decreases heart rate, not increases it. This can help reduce the oxygen demand of the heart, but it is not the main goal of therapy for variant angina.
Verapamil decreases contractility, not increases it. This can also help reduce the oxygen demand of the heart, but it is not the main goal of therapy for variant angina.
Verapamil is a calcium channel blocker that is used to treat variant angina by dilating the coronary arteries and relieving the chest pain caused by spasms. It also reduces blood pressure and heart rate, but these are not the expected outcomes for variant angina.
Verapamil reduces blood pressure, not increases it. This can help lower the workload of the heart, but it is not the main goal of therapy for variant angina.

Choice A is wrong because verapamil decreases heart rate, not increases it. This can help reduce the oxygen demand of the heart, but it is not the main goal of therapy for variant angina.
Choice B is wrong because verapamil decreases contractility, not increases it. This can also help reduce the oxygen demand of the heart, but it is not the main goal of therapy for variant angina.
Choice D is wrong because verapamil reduces blood pressure, not increases it. This can help lower the workload of the heart, but it is not the main goal of therapy for variant angina.
Normal ranges for heart rate are 60 to 100 beats per minute, for blood pressure are 120/80 mm Hg or lower, and for contractility are measured by ejection fraction, which is normally 55% or higher.
