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

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.

2. The client is prescribed warfarin. What should the client be taught about this medication?

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is an anticoagulant medication, and vitamin K can counteract its effects. Therefore, it is important for clients taking warfarin to avoid foods high in vitamin K to maintain the medication's effectiveness. Choice B is incorrect because warfarin should be taken consistently as prescribed, regardless of food intake. Choice C is incorrect because while consistency in timing is important, it is not specific to the effectiveness of warfarin. Choice D is incorrect because clients should never increase the dose of warfarin on their own, especially to make up for a missed dose, as it can lead to serious bleeding risks.

3. What is the condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?

Correct answer: A

Rationale: The correct answer is A, Peripheral artery disease (PAD). PAD is a condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, leading to decreased blood flow, pain, and difficulty walking, especially during physical activity. Raynaud's disease (choice B) is characterized by vasospasms in the fingers and toes, causing them to turn white or blue. Varicose veins (choice C) are enlarged, twisted veins usually found in the legs. Pulmonary embolism (choice D) is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot.

4. What is the condition where the blood flow through the coronary arteries is reduced or blocked, leading to chest pain or heart attack?

Correct answer: A

Rationale: The correct answer is A, Coronary artery disease (CAD). CAD occurs when the coronary arteries are narrowed or blocked, reducing blood flow to the heart muscle and increasing the risk of chest pain or heart attack. Choice B, Atherosclerosis, is a condition characterized by the hardening and narrowing of arteries due to the buildup of plaque. Choices C and D, Pulmonary embolism and Pulmonary hypertension, involve issues related to the lungs and not the coronary arteries.

5. This is a chronic condition where the heart is unable to pump enough blood to meet the body's needs.

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 enough blood to meet the body's needs, resulting in symptoms such as fatigue, shortness of breath, and fluid retention. Choice B, Cardiomyopathy, refers to diseases of the heart muscle that can lead to heart failure but is not the specific term for the condition described. Choices C and D, Myocarditis and Pericarditis, respectively, are conditions involving inflammation of the heart muscle or the lining around the heart, which can cause heart failure as a complication but are not the primary condition described in the question.
