Nursing Elites

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

• A. Administer vitamin K as an antidote.
• B. Hold the next dose of warfarin.
• C. Increase the dose of warfarin.
• D. Monitor the client’s INR closely.

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. What type of therapy delivers high concentrations of oxygen to the lungs?

• A. Oxygen therapy
• B. Ventilator therapy
• C. Mechanical ventilation
• D. CPAP therapy

Correct answer: A

Rationale: Oxygen therapy is the correct answer because it specifically refers to a treatment that delivers high concentrations of oxygen to the lungs. This therapy is used for patients who require additional oxygen due to conditions affecting their breathing. Ventilator therapy (B), mechanical ventilation (C), and CPAP therapy (D) involve different mechanisms and purposes than delivering high concentrations of oxygen to the lungs.

3. What is a severe and often sudden allergic reaction that can lead to breathing difficulties and anaphylactic shock?

• A. Anaphylaxis
• B. Allergic rhinitis
• C. Bronchospasm
• D. Asthma attack

Correct answer: A

Rationale: Anaphylaxis is the correct answer. It is a severe allergic reaction that can result in difficulty breathing, a drop in blood pressure, and even anaphylactic shock if not treated promptly. Choice B, allergic rhinitis, is characterized by symptoms such as a runny or stuffy nose, sneezing, and itching. Choice C, bronchospasm, refers to the sudden constriction of the muscles in the walls of the bronchioles, leading to breathing difficulties. Choice D, asthma attack, involves the inflammation and narrowing of the airways, resulting in symptoms like wheezing, coughing, and chest tightness.

4. What is a chronic condition where the heart is unable to pump blood effectively, leading to fluid buildup in the lungs and other parts of the body?

• A. Heart failure
• B. Myocardial infarction
• C. Pericarditis
• D. Pulmonary edema

Correct answer: A

Rationale: The correct answer is A: Heart failure. Heart failure is a chronic condition characterized by the heart's inability to pump blood effectively, resulting in fluid accumulation in the lungs and other body tissues. Myocardial infarction (choice B) refers to a heart attack caused by a blocked coronary artery, leading to damage of heart muscle tissue. Pericarditis (choice C) is the inflammation of the pericardium, the protective sac around the heart. Pulmonary edema (choice D) is a condition where fluid builds up in the lungs, often as a result of heart failure.

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?

• A. Alpha-1 antitrypsin deficiency
• B. Cystic fibrosis
• C. Wegener's granulomatosis
• D. Marfan syndrome

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.
