1. Which condition is characterized by the narrowing or blockage of arteries that supply blood to the heart by plaque?

• A. Coronary artery disease (CAD)
• B. Atherosclerosis
• C. Peripheral artery disease
• D. Congestive heart failure

Correct answer: A

Rationale: The correct answer is A, Coronary artery disease (CAD). CAD specifically refers to the condition where the arteries supplying blood to the heart become narrowed or blocked by plaque buildup. Choice B, Atherosclerosis, is a general term for the hardening and narrowing of arteries due to plaque buildup but does not specifically mention the heart. Choice C, Peripheral artery disease, involves narrowing of arteries that supply blood to areas other than the heart. Choice D, Congestive heart failure, is a condition where the heart is unable to pump blood effectively but is not primarily caused by narrowed or blocked arteries.

2. Which condition occurs when the heart muscle is damaged due to a lack of oxygen, often resulting from a heart attack?

• A. Myocardial infarction
• B. Angina
• C. Pericarditis
• D. Pulmonary embolism

Correct answer: A

Rationale: The correct answer is A: Myocardial infarction. Myocardial infarction, commonly known as a heart attack, is the condition where the heart muscle is damaged due to a lack of oxygen, typically caused by a blocked coronary artery. Angina (choice B) is chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. Pericarditis (choice C) is the inflammation of the pericardium, the thin sac-like membrane surrounding the heart. Pulmonary embolism (choice D) is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot.

3. The client is on nitroglycerin and reports chest pain. What is the nurse’s priority action?

• A. Administer nitroglycerin as ordered.
• B. Administer morphine as ordered.
• C. Administer aspirin as ordered.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: The correct answer is D: Notify the healthcare provider immediately. If a client on nitroglycerin reports chest pain, the priority action is to notify the healthcare provider immediately. This is crucial to ensure prompt reassessment of the client's condition and treatment plan. Administering nitroglycerin, morphine, or aspirin without consulting the healthcare provider first can be risky as the chest pain may indicate a need for a change in treatment or further evaluation. Administering medications without proper assessment and guidance can lead to complications and is not recommended in this scenario.

4. What procedure is used to remove fluid from the pleural space to help a patient breathe more easily?

• A. Thoracentesis
• B. Bronchoscopy
• C. Echocardiogram
• D. CT scan

Correct answer: A

Rationale: Thoracentesis is the correct answer. It is a procedure where a needle is inserted into the pleural space to drain fluid, relieving pressure and helping the patient breathe more easily. Bronchoscopy (choice B) is a procedure used to examine the airways, not to drain fluid. An echocardiogram (choice C) is an imaging test to assess the heart's structure and function, not related to draining pleural fluid. A CT scan (choice D) is a cross-sectional imaging test that provides detailed pictures of the inside of the body, not used for draining pleural fluid.

5. This is the inflammation of the heart's inner lining, usually caused by an infection.

• A. Endocarditis
• B. Myocarditis
• C. Pericarditis
• D. Valvulitis

Correct answer: A

Rationale: Endocarditis is the inflammation of the inner lining of the heart's chambers and valves, usually caused by a bacterial infection. Myocarditis is the inflammation of the heart muscle, Pericarditis is the inflammation of the pericardium (the outer lining of the heart), and Valvulitis is the inflammation of the heart valves. Therefore, in this case, the correct answer is Endocarditis as it specifically refers to the inflammation of the heart's inner lining.
