1. The nurse is caring for a client on warfarin with an INR of 5.2. What is the most appropriate action?

Correct answer: A

Rationale: An INR of 5.2 is elevated, indicating an increased risk of bleeding. Administering vitamin K can help reverse the effects of warfarin, which is the most appropriate action in this situation. Holding the next dose of warfarin is not enough to address the high INR, and increasing the dose would further elevate the INR level. Monitoring the INR closely is important, but in this case, immediate action is needed to counteract the anticoagulant effects of warfarin.

2. When monitoring a client on dobutamine, what is the most important parameter to assess?

Correct answer: A

Rationale: The correct answer is A: Blood pressure. When a client is on dobutamine, it is crucial to closely monitor their blood pressure as dobutamine can cause significant changes in blood pressure. While heart rate is also important to monitor during this time, blood pressure is the most critical parameter to assess. Oxygen saturation and respiratory rate are also important parameters to monitor in a patient receiving dobutamine, but they are not as crucial as blood pressure in this scenario.

3. What is a condition where the blood pressure in the arteries is consistently too high, increasing the risk of heart disease and stroke?

Correct answer: A

Rationale: Hypertension, also known as high blood pressure, is a condition where the force of the blood against the artery walls is consistently too high. This increased pressure can lead to serious health issues such as heart disease and stroke. Hypotension (choice B) refers to low blood pressure, which is not the correct term in this context. Diabetes (choice C) and hyperlipidemia (choice D) are also serious conditions but are not specifically characterized by consistently high blood pressure.

4. Which term describes an abnormal heartbeat that can be either too fast or too slow?

Correct answer: A

Rationale: The correct answer is A: Arrhythmia. Arrhythmia is a broad term that refers to any irregularity in the heart's rhythm, which can manifest as a heartbeat that is too fast (tachycardia), too slow (bradycardia), or irregular. Choice B, Bradycardia, specifically denotes a slow heart rate, while choice C, Tachycardia, refers to a fast heart rate. Choice D, Conductivity, is not the correct term to describe an abnormal heartbeat characterized by speed irregularities.

5. Which of the following is a rare genetic disorder that affects the lungs, liver, and skin, causing the buildup of a specific protein that damages organs?

Correct answer: A

Rationale: The correct answer is Alpha-1 antitrypsin deficiency. This disorder leads to the accumulation of a specific protein that can harm the lungs, liver, and skin. Choice B, Cystic fibrosis, is incorrect because it primarily affects the lungs and digestive system due to a defective gene. Choice C, Wegener's granulomatosis, is an autoimmune disease that involves inflammation of blood vessels, not protein buildup. Choice D, Marfan syndrome, is a connective tissue disorder impacting the heart, blood vessels, bones, and eyes, but not involving protein accumulation that damages organs.
