Cardiovascular System Practice Questions Questions
Question 1 of 5
The client is being taught about their warfarin. What does the nurse say about warfarin?
Correct Answer: A
Rationale: The correct answer is A because warfarin antagonizes vitamin K, essential for clotting factor production. This leads to reduced clotting factor synthesis, preventing blood clots. Option B is incorrect as warfarin doesn't act as an antiplatelet drug but affects clotting factors. Option C is incorrect as warfarin doesn't cause fibrinolysis but hinders clot formation. Option D is incorrect as warfarin doesn't directly inactivate clotting factors, but rather interferes with their production.
Question 2 of 5
The client has been prescribed gemfibrozil. The nurse explains the function of the drug as what?
Correct Answer: D
Rationale: The correct answer is D: It lowers triglyceride levels. Gemfibrozil is a fibric acid derivative that primarily works by lowering triglyceride levels. It does not directly reduce cholesterol levels (A), destabilize cholesterol plaques (B), or prevent a recurrent MI (C). It is important to understand the specific mechanism of action of gemfibrozil to provide accurate patient education.
Question 3 of 5
The nurse is assessing the client’s capillary refill. A normal capillary refill time is what?
Correct Answer: A
Rationale: The correct answer is A (Less than 1 second) because normal capillary refill time is typically less than 1 second. Capillary refill time measures the time it takes for blood to return to the capillaries after pressure is applied and released. This quick refill indicates adequate peripheral circulation. Choices B, C, and D (3 seconds, 5 seconds, and 10 seconds) are incorrect as they indicate delayed capillary refill, which can be a sign of poor circulation or other underlying health issues. It is crucial for nurses to assess capillary refill time accurately to monitor circulation status and detect potential problems early.
Question 4 of 5
The client has a heart rate of 40 with electrical activity beginning at the AV node. What type of rhythm is the client having?
Correct Answer: D
Rationale: The correct answer is D: Junctional escape rhythm. With a heart rate of 40 and electrical activity starting at the AV node, it indicates a slow heart rate originating from the junctional tissue. This rhythm is considered an escape rhythm when the SA node fails to initiate an impulse. A: Normal sinus rhythm is characterized by a heart rate of 60-100 bpm originating from the SA node. B: Atrial flutter is a rapid regular atrial rhythm with a rate typically between 250-350 bpm. C: Atrial fibrillation is characterized by rapid and irregular atrial activity, not a slow rhythm like in this case.
Question 5 of 5
Which nursing intervention is likely to be most effective when assisting the patient with coronary artery disease to make appropriate dietary changes?
Correct Answer: B
Rationale: The correct answer is B: Help the patient modify favorite high-fat recipes by using monounsaturated oils. This answer is correct because it focuses on practical and sustainable dietary changes by modifying existing favorite recipes to make them healthier. By using monounsaturated oils instead of saturated fats, the patient can still enjoy their favorite foods while making positive changes to their diet. Option A is too restrictive in eliminating all saturated fats and may not be sustainable for the patient in the long term. Option C focuses on fear-based motivation, which is not always effective in promoting behavior change. Option D gives a list of foods without addressing how the patient can make practical changes in their meal preparation. Overall, option B is the most effective as it encourages gradual and realistic changes in the patient's diet.
