Nursing Elites

1. The nurse is preparing to administer a beta blocker to a client with hypertension. What is the priority assessment?

• A. Check the client's heart rate.
• B. Check the client's blood pressure.
• C. Check the client's respiratory rate.
• D. Check the client's temperature.

Correct answer: B

Rationale: The correct answer is to check the client's blood pressure. Before administering a beta blocker to a client with hypertension, assessing the blood pressure is crucial because beta blockers can cause hypotension, potentially leading to adverse effects. Checking the heart rate may also be important but is secondary to monitoring the blood pressure in this scenario. Respiratory rate and temperature assessments are not directly related to assessing the client's response to a beta blocker in hypertension management, making choices C and D less relevant.

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

• A. Avoid foods high in vitamin K.
• B. Take the medication with food to prevent stomach upset.
• C. Take the medication at the same time every day.
• D. Increase the dose if a dose is missed.

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. Which medication relaxes the muscles around the airways, making it easier to breathe?

• A. Bronchodilator
• B. Corticosteroid
• C. Antihistamine
• D. Mucolytic

Correct answer: A

Rationale: The correct answer is A, Bronchodilator. Bronchodilators are medications that relax the muscles surrounding the airways, which helps to open them and makes breathing easier. Corticosteroids (choice B) work by reducing inflammation, antihistamines (choice C) are used to manage allergies, and mucolytics (choice D) help to break down and thin mucus in the airways.

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

• A. Heart failure
• B. Cardiomyopathy
• C. Pericarditis
• D. Aortic stenosis

Correct answer: A

Rationale: Heart failure is the correct answer. It is a chronic condition characterized by the heart's inability to pump blood efficiently, resulting in symptoms like fluid buildup in the lungs and other parts of the body, shortness of breath, fatigue, and fluid retention. Cardiomyopathy (choice B) refers to diseases of the heart muscle, but it is a broader category that includes various conditions affecting the heart muscle. Pericarditis (choice C) is the inflammation of the pericardium, the sac surrounding the heart, and aortic stenosis (choice D) is a condition where the aortic valve narrows, restricting blood flow from the heart.

5. What is the condition where the walls of the heart's ventricles become thickened, reducing the heart's ability to pump blood effectively?

• A. Ventricular hypertrophy
• B. Atrial fibrillation
• C. Restrictive cardiomyopathy
• D. Cardiomyopathy

Correct answer: A

Rationale: Ventricular hypertrophy is the correct answer. In ventricular hypertrophy, the walls of the heart's ventricles become thickened, which decreases the heart's efficiency in pumping blood. Atrial fibrillation (choice B) is an irregular and often rapid heart rate that can lead to poor blood flow. While restrictive cardiomyopathy (choice C) involves the heart muscle becoming rigid and less compliant, it is not specifically characterized by thickening of the ventricular walls. Cardiomyopathy (choice D) is a general term for diseases of the heart muscle, which can present with various symptoms and causes.
