1. Which term refers to high blood pressure, a condition where the force of the blood against the artery walls is too high?

• A. Hypertension
• B. Hypotension
• C. Hyperlipidemia
• D. Diabetes

Correct answer: A

Rationale: The correct answer is A, Hypertension. Hypertension is a condition characterized by persistently high blood pressure, which increases the risk of heart disease and stroke. Choice B, Hypotension, refers to low blood pressure. Choice C, Hyperlipidemia, is the term for high levels of fats in the blood. Choice D, Diabetes, is a condition characterized by high blood sugar levels.

2. What is a condition where the heart muscle becomes abnormally enlarged, thickened, or stiffened, often leading to heart failure?

• A. Cardiomyopathy
• B. Pericarditis
• C. Aortic stenosis
• D. Mitral valve prolapse

Correct answer: A

Rationale: Cardiomyopathy is the correct answer. It is a condition characterized by the abnormal enlargement, thickening, or stiffening of the heart muscle, which can lead to heart failure. Pericarditis (choice B) is inflammation of the pericardium, the sac surrounding the heart, not directly related to heart muscle enlargement. Aortic stenosis (choice C) is the narrowing of the aortic valve opening, affecting blood flow from the heart, but not directly related to heart muscle enlargement. Mitral valve prolapse (choice D) is a condition where the valve between the left atrium and left ventricle doesn't close properly, causing blood to leak backward, and is not directly related to heart muscle enlargement.

3. What is a condition where the pulmonary arteries become blocked by a blood clot, leading to chest pain, shortness of breath, and other symptoms?

• A. Pulmonary embolism
• B. Pneumothorax
• C. Pulmonary edema
• D. Pulmonary hypertension

Correct answer: A

Rationale: The correct answer is A, pulmonary embolism. Pulmonary embolism is a condition where a blood clot blocks one of the pulmonary arteries in the lungs, resulting in symptoms like chest pain, shortness of breath, and other related signs. Choices B, C, and D are incorrect because pneumothorax refers to a collapsed lung, pulmonary edema is the build-up of fluid in the lungs, and pulmonary hypertension is high blood pressure in the arteries of the lungs - none of which directly involve a blood clot blocking the pulmonary arteries.

4. Which term describes a type of abnormal heart rhythm characterized by rapid and irregular beating of the atria?

• A. Atrial fibrillation
• B. Ventricular fibrillation
• C. Atrial flutter
• D. Sinus tachycardia

Correct answer: A

Rationale: The correct answer is Atrial fibrillation. Atrial fibrillation is indeed a type of abnormal heart rhythm characterized by rapid and irregular beating of the atria. This condition can increase the risk of stroke and heart failure. Choice B, Ventricular fibrillation, is incorrect because it refers to a life-threatening arrhythmia that occurs in the ventricles, not the atria. Choice C, Atrial flutter, is incorrect as it describes a different type of atrial arrhythmia characterized by a regular but fast heartbeat. Choice D, Sinus tachycardia, is incorrect because it is a normal increase in heart rate originating from the sinus node, not an abnormal rhythm.

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

• A. Heart failure
• B. Bradycardia
• C. Tachycardia
• D. Respiratory distress

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.
