Cardiovascular System Practice Questions Questions
Question 1 of 5
The client has a myocardial infarction and going into shock. What might be a medication to give to counteract shock in cases of myocardial infarction?
Correct Answer: B
Rationale: The correct answer is B: Dopamine. Dopamine is a medication used in cases of shock, including cardiogenic shock from a myocardial infarction. It helps to increase blood pressure and heart rate, improving cardiac output. Atropine (A) is used for bradycardia, not shock. Digoxin (C) is used for heart failure, not shock. Adenosine (D) is used for certain types of arrhythmias, not shock. Dopamine is the most appropriate choice to counteract shock in cases of myocardial infarction.
Question 2 of 5
The client is taking a calcium channel blocker for an arrhythmia. What is a contraindication to giving the client this drug?
Correct Answer: C
Rationale: The correct answer is C: Wolff-Parkinson White syndrome. This is because calcium channel blockers can exacerbate the accessory pathway in WPW syndrome, leading to potentially life-threatening arrhythmias. Choices A and B are not contraindications as calcium channel blockers are commonly used to manage hypertension and arrhythmias. Choice D, glaucoma, is not directly related to the use of calcium channel blockers for arrhythmias.
Question 3 of 5
The client has a decreased cardiac output. Which things can increase the client’s cardiac output? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Increased heart rate. Increasing heart rate can help increase cardiac output by pumping more blood with each heartbeat, compensating for the decreased output. Decreasing heart rate (choice A) would further reduce cardiac output. Increased blood volume (choice C) can increase preload and cardiac output, but only if the heart is able to handle the increased volume. Decreased venous return (choice D) would decrease preload and subsequently cardiac output. Therefore, choice B is the most appropriate option to increase cardiac output in this scenario.
Question 4 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 5 of 5
The client is taking Ticlid and is anticipating surgery. What does the nurse advice the client to do about taking the Ticlid around the time of surgery?
Correct Answer: A
Rationale: The correct answer is A: Ticlid should be withheld on the day of surgery. Ticlid is an antiplatelet medication that can increase the risk of bleeding during surgery. It is crucial to withhold Ticlid on the day of surgery to minimize the risk of excessive bleeding during the procedure. Choices B, C, and D are incorrect because taking Ticlid on the day of surgery or stopping it too far in advance can lead to increased bleeding risks. Stopping Ticlid a month before surgery (C) is unnecessary and can increase the risk of clot formation. Stopping Ticlid 7 days before surgery (D) is also too close to the surgery date and may not provide enough time for the medication to clear the system, potentially leading to increased bleeding risks.
