1. What is a condition where the airways become inflamed and narrow, making breathing difficult?

• A. Asthma
• B. Bronchitis
• C. Pleurisy
• D. Tuberculosis

Correct answer: A

Rationale: Asthma is the correct answer. It is a condition characterized by inflammation, narrowing, and swelling of the airways, leading to symptoms like wheezing, shortness of breath, and coughing. Bronchitis is the inflammation of the bronchial tubes; Pleurisy is inflammation of the tissues that line the lungs and chest cavity; Tuberculosis is a bacterial infection that mainly affects the lungs.

2. What test measures the pressure inside the arteries as the heart pumps blood?

• A. Blood pressure test
• B. Pulse oximetry
• C. Echocardiogram
• D. Spirometry

Correct answer: A

Rationale: The correct answer is A) Blood pressure test. A blood pressure test is specifically designed to measure the pressure inside the arteries as the heart pumps blood. This test is crucial in providing information about cardiovascular health by determining the force of blood against the artery walls. Choice B, Pulse oximetry, measures oxygen saturation in the blood, not blood pressure. Choice C, Echocardiogram, is an ultrasound test that evaluates the structure and function of the heart, not specifically blood pressure. Choice D, Spirometry, is a test used to assess lung function, not blood pressure.

3. The client on warfarin has an INR of 1.2. What is the nurse’s priority action?

• A. Increase the dose of warfarin
• B. Administer vitamin K
• C. Monitor for signs of bleeding
• D. Hold the next dose and notify the healthcare provider

Correct answer: A

Rationale: The correct answer is to increase the dose of warfarin. An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating that the dose is subtherapeutic. The priority action in this situation is to adjust the dose to achieve the target therapeutic INR range (usually 2-3) to prevent thromboembolic events. Administering vitamin K is not necessary as the INR is low, and there are no signs of bleeding. Monitoring for signs of bleeding is important but not the priority in this case since the INR is subtherapeutic. Holding the next dose and notifying the healthcare provider would delay the intervention needed to adjust the dose and achieve the therapeutic range.

4. What is a chronic lung disease that includes chronic bronchitis and emphysema?

• A. Chronic Obstructive Pulmonary Disease (COPD)
• B. Pneumonia
• C. Asthma
• D. Tuberculosis

Correct answer: A

Rationale: The correct answer is Chronic Obstructive Pulmonary Disease (COPD). COPD is a chronic lung condition that encompasses chronic bronchitis and emphysema, causing airflow obstruction from the lungs. Pneumonia (choice B) is an infection in the lungs, while asthma (choice C) is characterized by airway inflammation and constriction. Tuberculosis (choice D) is a bacterial infection that primarily affects the lungs but is distinct from COPD.

5. Which structure serves as the normal pacemaker of the heart?

• A. SA node
• B. AV node
• C. Purkinje fibers
• D. Atria

Correct answer: A

Rationale: The correct answer is the SA node. The sinoatrial (SA) node is known as the natural pacemaker of the heart as it generates electrical impulses initiating each heartbeat. The SA node is located in the right atrium and sets the rhythm and rate of the heartbeat. The AV node (choice B) is responsible for delaying the electrical impulse to allow the atria to contract before the ventricles. Purkinje fibers (choice C) are specialized cardiac fibers responsible for the rapid conduction of impulses to the myocardial cells, and the atria (choice D) are the upper chambers of the heart involved in receiving blood from the veins.
