1. What is the procedure where a catheter is used to open a blocked or narrowed coronary artery, often involving the placement of a stent?

• A. Angioplasty
• B. Valve replacement
• C. Stent placement
• D. Coronary artery bypass graft (CABG)

Correct answer: A

Rationale: The correct answer is Angioplasty. Angioplasty is a procedure where a catheter is used to open a blocked or narrowed coronary artery, often involving the placement of a stent to keep the artery open and improve blood flow to the heart. Choice B, Valve replacement, is incorrect as it involves replacing a heart valve, not opening a blocked artery. Choice C, Stent placement, is similar to angioplasty but not as specific, as it does not involve the catheter-based procedure. Choice D, Coronary artery bypass graft (CABG), is a different procedure where blocked arteries are bypassed using a blood vessel from another part of the body.

2. What is a type of heart disease that involves the thickening or stiffening of the heart muscle, reducing its ability to pump blood?

• A. Hypertrophic cardiomyopathy
• B. Dilated cardiomyopathy
• C. Restrictive cardiomyopathy
• D. Arrhythmia

Correct answer: A

Rationale: Hypertrophic cardiomyopathy is a type of heart disease characterized by the thickening or stiffening of the heart muscle, leading to a reduced ability to pump blood. This condition is different from dilated cardiomyopathy (choice B), which involves the enlargement and weakening of the heart chambers. Restrictive cardiomyopathy (choice C) is characterized by the stiffening of the heart muscle, affecting its ability to fill with blood properly. Arrhythmia (choice D) refers to abnormal heart rhythms and is not specifically related to thickening or stiffening of the heart muscle, as seen in hypertrophic cardiomyopathy.

3. What type of medication is used to reduce inflammation in the airways and prevent asthma attacks?

• A. Corticosteroid
• B. Bronchodilator
• C. Antihistamine
• D. Mucolytic

Correct answer: A

Rationale: The correct answer is A, Corticosteroid. Corticosteroids are medications that work by reducing inflammation in the airways, helping to prevent asthma attacks and manage chronic respiratory conditions. Bronchodilators (choice B) work by relaxing the muscles around the airways to make breathing easier, but they do not primarily target inflammation. Antihistamines (choice C) are used to treat allergic reactions and do not directly target airway inflammation. Mucolytics (choice D) help to break down and thin mucus in the airways but do not reduce inflammation.

4. A client on spironolactone (Aldactone) has a potassium level of 6.0 mEq/L. What is the nurse’s priority action?

• A. Hold the spironolactone and notify the healthcare provider.
• B. Administer a potassium supplement.
• C. Continue the spironolactone as ordered.
• D. Increase the dose of spironolactone.

Correct answer: A

Rationale: The correct action for a client on spironolactone with a potassium level of 6.0 mEq/L is to hold the medication and notify the healthcare provider. Spironolactone is a potassium-sparing diuretic that can further elevate potassium levels, which are already high. Administering a potassium supplement (Choice B) would exacerbate the hyperkalemia. Continuing the spironolactone as ordered (Choice C) could lead to worsening hyperkalemia. Increasing the dose of spironolactone (Choice D) would be contraindicated in the presence of elevated potassium levels.

5. Which surgical procedure involves opening or replacing a narrowed or blocked heart valve?

• A. Valve replacement
• B. Angioplasty
• C. Stent placement
• D. Coronary bypass surgery

Correct answer: A

Rationale: Valve replacement is the correct answer because it specifically involves surgically replacing a damaged or diseased heart valve with a prosthetic valve to address narrowing or blockage, thereby improving blood flow and heart function. Angioplasty (choice B) is a procedure to widen narrowed or obstructed arteries, typically using a balloon catheter. Stent placement (choice C) involves inserting a mesh tube to support a weakened artery. Coronary bypass surgery (choice D) is a procedure to create new routes for blood flow to the heart muscle by bypassing blocked arteries.
