ATI RN
Pharmacology ATI Proctored Exam 2023 Questions
Question 1 of 5
A client has been prescribed a calcium channel blocker for angina. The nurse knows this medication should NOT be used with caution in combination with which drug classes?
Correct Answer: C
Rationale: Calcium channel blockers and beta blockers should be used with caution together because they can both suppress heart function, potentially leading to bradycardia, heart block, or heart failure. NSAIDs and cardiac glycosides do not have significant interactions with calcium channel blockers in the same way, so they are not typically a cause for concern when combined.
Question 2 of 5
The client asks the nurse about common side effects of calcium channel blockers. What should the nurse include in client teaching?
Correct Answer: A
Rationale: One of the common side effects of calcium channel blockers is a headache. This is important information for the nurse to include in client teaching as it helps the client understand potential adverse effects of the medication. Constipation, epistaxis, and dysuria are not typically associated with calcium channel blockers.
Question 3 of 5
The client with angina is being discharged to home. The nurse is instructing the client on dietary changes. What should be included in this teaching?
Correct Answer: A
Rationale: The correct answer is to decrease salt and fat intake and limit alcohol intake. These dietary changes can help manage angina by reducing the workload on the heart and preventing further plaque buildup in the arteries. Choices B, C, and D are incorrect as dietary restrictions for angina typically involve reducing salt, fat, and alcohol intake, rather than increasing sugar or cholesterol intake.
Question 4 of 5
Which drug class has been found to decrease mortality if given within 8 hours of an MI due to a decrease in cardiac workload?
Correct Answer: B
Rationale: Beta-adrenergic blockers have been shown to decrease mortality when administered within 8 hours of a myocardial infarction (MI). They do so by reducing cardiac workload, which helps improve outcomes post-MI. These drugs work by blocking the effects of adrenaline on the heart, leading to decreased heart rate, blood pressure, and myocardial oxygen demand, thereby protecting the heart muscle from further damage. This makes them a crucial part of the treatment regimen for acute coronary syndromes like MI.
Question 5 of 5
The nurse is caring for a client who has chronic angina. Treatment for the condition has been unsuccessful. Which medication does the nurse anticipate will be prescribed?
Correct Answer: D
Rationale: In cases of chronic angina where initial treatment has not been successful, Ranolazine (Ranexa) is often prescribed. This medication helps by reducing the frequency of angina episodes. Atenolol, Nitroglycerin, and Sildenafil are also used in angina management but Ranolazine is more specifically indicated in cases of refractory angina where other treatments have failed.
