1. Which type of medication helps to reduce the workload on the heart by slowing down the heart rate?

• A. Beta-blocker
• B. Calcium channel blocker
• C. Diuretic
• D. ACE inhibitor

Correct answer: A

Rationale: Beta-blockers are medications that work by blocking the action of hormones like adrenaline, thereby reducing the heart rate and the workload on the heart. This makes them effective in managing high blood pressure and various heart conditions. Calcium channel blockers work by relaxing blood vessels and reducing the heart's workload, but they do not primarily slow down the heart rate. Diuretics help the body get rid of excess salt and water by increasing urine production, which can lower blood pressure but not by slowing down the heart rate. ACE inhibitors work by relaxing blood vessels, not by directly affecting heart rate.

2. What is the condition where the blood flow through the coronary arteries is reduced or blocked, leading to chest pain or heart attack?

• A. Coronary artery disease
• B. Atherosclerosis
• C. Pulmonary embolism
• D. Pulmonary hypertension

Correct answer: A

Rationale: The correct answer is A, Coronary artery disease (CAD). CAD occurs when the coronary arteries are narrowed or blocked, reducing blood flow to the heart muscle and increasing the risk of chest pain or heart attack. Choice B, Atherosclerosis, is a condition characterized by the hardening and narrowing of arteries due to the buildup of plaque. Choices C and D, Pulmonary embolism and Pulmonary hypertension, involve issues related to the lungs and not the coronary arteries.

3. 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.

4. What is a severe allergic reaction that can cause difficulty breathing and shock?

• A. Anaphylaxis
• B. Asthma attack
• C. Bronchospasm
• D. Hypersensitivity

Correct answer: A

Rationale: Anaphylaxis is the correct answer. It is a severe, potentially life-threatening allergic reaction that can lead to difficulty breathing, low blood pressure, and loss of consciousness. An asthma attack is a separate condition characterized by narrowed airways and difficulty breathing, but it is not necessarily related to an allergic reaction like anaphylaxis. Bronchospasm refers to the sudden constriction of muscles in the bronchi, leading to breathing difficulties, and is not specific to allergic reactions. Hypersensitivity is a general term for an exaggerated immune response to a substance, which may or may not manifest as severe allergic reactions like anaphylaxis.

5. The client on enoxaparin (Lovenox) is scheduled for surgery. What is the nurse’s priority action?

• A. Hold the enoxaparin and notify the healthcare provider.
• B. Administer the enoxaparin as scheduled.
• C. Administer vitamin K before the surgery.
• D. Monitor the client’s INR and proceed with surgery.

Correct answer: A

Rationale: The correct answer is A: Hold the enoxaparin and notify the healthcare provider. Enoxaparin, being an anticoagulant, should be held before surgery to reduce the risk of excessive bleeding during the procedure. It is crucial to inform the healthcare provider to determine the appropriate management plan. Choice B is incorrect because administering enoxaparin before surgery can increase the risk of bleeding. Choice C is incorrect as vitamin K administration is not typically indicated in this situation. Choice D is incorrect because monitoring the client's INR and proceeding with surgery without addressing the enoxaparin can lead to significant bleeding complications.
