1. What is a condition where the heart muscle is weakened and unable to pump blood effectively, often leading to heart failure?

• A. Cardiomyopathy
• B. Myocarditis
• C. Endocarditis
• D. Pericarditis

Correct answer: A

Rationale: Cardiomyopathy is the correct answer. In cardiomyopathy, the heart muscle becomes weak and cannot pump blood effectively, which can lead to heart failure. Myocarditis (choice B) is inflammation of the heart muscle, not specifically causing muscle weakness. Endocarditis (choice C) is an infection of the inner lining of the heart chambers and valves. Pericarditis (choice D) is inflammation of the pericardium, the outer lining of the heart.

2. The client is on nitroglycerin and reports chest pain. What is the nurse’s priority action?

• A. Administer nitroglycerin as ordered.
• B. Administer morphine as ordered.
• C. Administer aspirin as ordered.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: The correct answer is D: Notify the healthcare provider immediately. If a client on nitroglycerin reports chest pain, the priority action is to notify the healthcare provider immediately. This is crucial to ensure prompt reassessment of the client's condition and treatment plan. Administering nitroglycerin, morphine, or aspirin without consulting the healthcare provider first can be risky as the chest pain may indicate a need for a change in treatment or further evaluation. Administering medications without proper assessment and guidance can lead to complications and is not recommended in this scenario.

3. What procedure involves inserting a needle into the pleural space to remove excess fluid and help the patient breathe more easily?

• A. Thoracentesis
• B. Bronchoscopy
• C. Spirometry
• D. Arterial blood gas (ABG)

Correct answer: A

Rationale: Thoracentesis is the correct answer. It is a procedure where a needle is inserted into the pleural space to remove excess fluid, aiding in easier breathing. Bronchoscopy (Choice B) is a procedure to visualize the airways and diagnose lung problems, not specifically for fluid drainage. Spirometry (Choice C) is a test to measure lung function, not a procedure for fluid removal. Arterial blood gas (ABG) (Choice D) is a blood test to assess oxygen and carbon dioxide levels in the blood, not a procedure for draining fluid from the pleural space.

4. Identify the three layers of the heart:

• A. Endocardium, Myocardium, Epicardium
• B. Epicardium, Pericardium, Endocardium
• C. Myocardium, Endocardium, Pericardium
• D. Pericardium, Myocardium, Endocardium

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.

5. What is the ability of cardiac cells to respond to an impulse by contracting?

• A. Excitability
• B. Contractility
• C. Rhythmicity
• D. Conductivity

Correct answer: A

Rationale: Excitability is the correct term that describes the ability of cardiac cells to respond to an impulse by contracting. Excitability refers to the cell's ability to respond to stimuli and generate an action potential. Choice B, Contractility, is incorrect as it refers to the ability of cardiac cells to contract after receiving a stimulus, not the response to the impulse itself. Choice C, Rhythmicity, is incorrect as it pertains to the heart's ability to contract rhythmically without external stimulation. Choice D, Conductivity, is incorrect as it refers to the ability of cardiac cells to transmit an impulse from cell to cell, not the direct response to the impulse by contracting.
