Question 23 1 out of 1 points Several months of treatment with a statin accompanied by lifestyle modifications have failed to appreciably improve a patient's cholesterol levels. Consequently, the patient has been prescribed cholestyramine. The nurse should recognize that this drugs achieves its therapeutic effect by Response Feedback: Unlike statins, which work by decreasing the synthesis of cholesterol, the bile acid sequestrants such as cholestyramine promote the oxidation of cholesterol to bile acids. Bile acid sequestrants do not promote vasodilation or bind HDL to LDL. Question 24 1 out of 1 points A 58-year-old man is admitted to the emergency department. A diagnosis of severe digoxin toxicity is made. Bradycardia is present, and an electrocardiogram (ECG) confirms toxicity. The nurse will administer which of the following drugs?

Question 25 1 out of 1 points A 70-year-old woman with a history of atrial fibrillation takes digoxin and verapamil to control her health problem.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
