1. 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.

2. What is the procedure where a device is used to shock the heart back into a normal rhythm during a life-threatening arrhythmia?

• A. Defibrillation
• B. Cardioversion
• C. Echocardiogram
• D. Ablation

Correct answer: A

Rationale: The correct answer is A, Defibrillation. Defibrillation is the procedure of using a device to deliver an electric shock to the heart during life-threatening arrhythmias like ventricular fibrillation or ventricular tachycardia to restore a normal rhythm. Choice B, Cardioversion, is similar but is typically used for less severe arrhythmias. Choice C, Echocardiogram, is a diagnostic test that uses sound waves to create images of the heart. Choice D, Ablation, is a procedure to treat certain types of arrhythmias by scarring or destroying tissue that triggers abnormal electrical signals.

3. Which test measures how well the lungs work by assessing the amount of air the lungs can hold and how quickly air can be exhaled?

• A. Spirometry
• B. Pulse oximetry
• C. Arterial blood gas (ABG)
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A, Spirometry. Spirometry is a pulmonary function test that evaluates lung function by measuring the amount of air a person can exhale and how quickly, assisting in the diagnosis of conditions such as asthma and COPD. Choices B, C, and D are incorrect because Pulse oximetry measures oxygen saturation in the blood, Arterial blood gas (ABG) evaluates blood pH, oxygen, and carbon dioxide levels, and a Chest X-ray provides an image of the lungs but does not measure lung function.

4. What is the ability of cardiac cells to generate an electrical impulse without being stimulated by an external source?

• A. Automaticity
• B. Contractility
• C. Conductivity
• D. Refractoriness

Correct answer: A

Rationale: Automaticity is the correct answer because it refers to the inherent ability of cardiac cells to generate electrical impulses without the need for external stimulation. Contractility (Choice B) is the ability of the heart muscle to contract and generate force, not related to electrical impulse generation. Conductivity (Choice C) refers to the ability of cardiac cells to transmit electrical impulses from cell to cell, not the spontaneous generation of impulses. Refractoriness (Choice D) is the period during which the cardiac cells are recovering and not able to respond to a new stimulus, not the spontaneous generation of impulses.

5. The client on spironolactone (Aldactone) has a potassium level of 5.8 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: With a potassium level of 5.8 mEq/L, which is high, the priority action for the nurse is to hold the spironolactone. Spironolactone is a potassium-sparing diuretic that can further increase potassium levels. Therefore, it is crucial to prevent exacerbating hyperkalemia by discontinuing the medication. Notifying the healthcare provider is necessary for further guidance and potential adjustments to the treatment plan. Administering a potassium supplement (Choice B) would be contraindicated since the client already has elevated potassium levels. Continuing the spironolactone as ordered (Choice C) can worsen hyperkalemia. Increasing the dose of spironolactone (Choice D) would be unsafe and exacerbate the high potassium levels.
