1. What is a condition where a blood clot forms in a vein, often in the legs, which can cause pain and swelling and may lead to serious complications if it travels to the lungs?

Correct answer: A

Rationale: Deep vein thrombosis (DVT) is the correct answer. It is a condition where a blood clot forms in a deep vein, usually in the legs. If the clot breaks loose and travels to the lungs, it can cause a pulmonary embolism. Varicose veins are enlarged, twisted veins that are not typically associated with blood clots. Aneurysm is the abnormal swelling or bulging of a blood vessel.

2. The client is on dobutamine. Adverse effects of Dobutrex (dobutamine) include the following: Select all that apply.

Correct answer: C

Rationale: The correct answer is C: Tachycardia. Dobutamine is a medication that primarily increases heart rate (tachycardia) and blood pressure. Therefore, the adverse effects of dobutamine include tachycardia. Choices A, B, and D are incorrect. Heart failure is not an adverse effect of dobutamine; in fact, it is used to treat heart failure by increasing heart contractility. Bradycardia (slow heart rate) is not an expected adverse effect of dobutamine, as it usually increases heart rate. Respiratory distress is not a common adverse effect of dobutamine.

3. The client on warfarin has an INR of 5.5. What is the priority nursing action?

Correct answer: A

Rationale: An INR of 5.5 is significantly elevated, indicating an increased risk of bleeding. The priority nursing action in this situation is to administer vitamin K as an antidote to reverse the effects of warfarin and lower the INR. Holding the next dose of warfarin (choice B) is important but not as immediate as administering vitamin K. Increasing the dose of warfarin (choice C) would further elevate the INR, worsening the bleeding risk. Administering fresh frozen plasma (choice D) is not the first-line treatment for high INR due to warfarin.

4. For what reason might the nurse be given an order to administer milrinone (Primacor)?

Correct answer: A

Rationale: Milrinone is commonly prescribed for congestive heart failure to help improve cardiac function and alleviate symptoms. Choices B, C, and D are incorrect as milrinone is not typically used for hypertension, cardiac arrhythmias, or bradycardia. It is specifically indicated for congestive heart failure for short-term management.

5. What is a surgical procedure where a blood vessel is grafted to bypass a blocked coronary artery, improving blood flow to the heart muscle?

Correct answer: A

Rationale: The correct answer is A: Coronary artery bypass graft (CABG). CABG involves grafting a blood vessel to bypass a blocked coronary artery, enhancing blood flow to the heart muscle. This procedure helps reduce the risk of heart attack by restoring proper blood circulation to the heart. Choice B, valve replacement, is a different surgical procedure that involves replacing damaged or dysfunctional heart valves. Choice C, angioplasty, is a minimally invasive procedure that uses a balloon to open narrowed or blocked blood vessels. Choice D, endarterectomy, is the surgical removal of plaque from the lining of an artery to improve blood flow.
