1. Which artery supplies the right atrium, right ventricle, a portion of the septum, SA node, AV node, and inferior portion of the left ventricle?

Correct answer: A

Rationale: The correct answer is the right coronary artery. It supplies essential areas of the heart, including the right atrium, right ventricle, a portion of the septum, SA node, AV node, and the inferior portion of the left ventricle. The left circumflex artery primarily supplies the left atrium and lateral wall of the left ventricle, not the mentioned areas. The posterior descending artery supplies the inferior wall of the left ventricle, not the right side. The aortic artery is a general term and does not specifically refer to an artery that supplies the mentioned areas.

2. What is a condition where the lungs become stiff and scarred, making it difficult to breathe and get enough oxygen into the bloodstream?

Correct answer: A

Rationale: Pulmonary fibrosis is a condition characterized by the stiffening and scarring of the lungs, leading to difficulty breathing and impairing the transfer of oxygen into the bloodstream. Pulmonary edema refers to fluid accumulation in the lungs, causing breathing difficulties due to fluid filling the air sacs. Pulmonary embolism is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot. Pulmonary hypertension is high blood pressure in the arteries of the lungs, which can lead to strain on the heart and affect oxygen levels in the blood.

3. Identify the three layers of the heart:

Correct answer: A

Rationale: The correct answer is A: Endocardium, Myocardium, Epicardium. The heart consists of three main layers: the endocardium, which lines the inner chambers of the heart; the myocardium, the middle layer responsible for the heart's pumping action; and the epicardium, the outermost layer that protects the heart. Choices B, C, and D are incorrect as they do not list the heart's layers in the correct order or combination.

4. A client on a beta blocker has a heart rate of 52 bpm. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct answer is to hold the beta blocker and notify the healthcare provider. A heart rate of 52 bpm is low, and beta blockers can further decrease the heart rate, potentially causing harm. Therefore, withholding the medication and promptly informing the healthcare provider is crucial for further assessment and possible adjustment of the treatment plan. Administering the beta blocker as ordered (Choice B) can exacerbate the bradycardia. Increasing the dose of the beta blocker (Choice C) would further suppress the heart rate. Continuing to monitor the client and reassessing in 30 minutes (Choice D) might delay necessary interventions and increase the risk of complications in a client with a heart rate of 52 bpm.

5. What is a chronic inflammatory disease that affects the small airways in the lungs, leading to episodes of wheezing, breathlessness, and coughing?

Correct answer: A

Rationale: Asthma is the correct answer. It is a chronic inflammatory disease that affects the small airways in the lungs, leading to symptoms like wheezing, breathlessness, and coughing. Asthma is commonly triggered by allergens, exercise, respiratory infections, and other factors. Choice B, COPD (Chronic Obstructive Pulmonary Disease), is characterized by airflow limitation and is often caused by smoking. Choice C, Bronchitis, is an inflammation of the bronchial tubes and can be acute or chronic. Choice D, Lung cancer, is a disease characterized by uncontrolled cell growth in lung tissues and is commonly associated with smoking or environmental factors.
