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.)
Decreased heart rate
Increased contractility
Dilated coronary arteries
Reduced blood pressure E.
Relieved chest pain.
Correct Answer : C,E
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.
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.

Correct Answer is ["A","E"]
Explanation
The nurse should include headache and dyspnea as potential adverse effects of bivalirudin.According to the drug information from various sources, bivalirudin can cause common side effects such as headache, nausea, low or high blood pressure, chest pain, abdominal pain, and shortness of breath (dyspnea).
These side effects should be reported to the provider if they are severe or persistent.
Choice B is wrong because fever is not a common side effect of bivalirudin.
However, fever can be a sign of infection or an allergic reaction to the drug, which should be reported to the provider immediately.
Choice C is wrong because chest pain is not an adverse effect of bivalirudin, but rather a symptom of angina, which is one of the conditions that bivalirudin is used to treat.
Chest pain can also indicate a heart attack or other serious cardiac problems, which require immediate medical attention.
Choice D is wrong because backache is not a common side effect of bivalirudin.
However, backache can be a sign of bleeding in the kidneys or other organs, which can be a serious complication of bivalirudin therapy.
Therefore, any unusual pain or swelling in the back or abdomen should be reported to the provider as soon as possible.
Correct Answer is B
Explanation
Argatroban is a direct thrombin inhibitor (DTI) that is used as an alternative anticoagulant for patients with heparin-induced thrombocytopenia (HIT) who require urgent surgery. Argatroban has a half-life of about 40 to 50 minutes and is cleared by the liver.The infusion should be stopped at least 4 hours before the surgery to allow adequate time for the anticoagulant effect to wear off.The activated partial thromboplastin time (aPTT) should be monitored before and after the infusion to assess the degree of anticoagulation.
Choice A is wrong because 2 hours is not enough time to stop the argatroban infusion before surgery.
The patient may still have a high risk of bleeding if the aPTT is prolonged.
Choice C is wrong because 6 hours is longer than necessary to stop the argatroban infusion before surgery.
The patient may have a higher risk of thrombosis if the anticoagulation effect is too low.
Choice D is wrong because 8 hours is much longer than necessary to stop the argatroban infusion before surgery.
The patient may have a very low level of anticoagulation and a high risk of thrombosis if the infusion is stopped for too long.
