Nursing Elites

1. Which condition is characterized by the right ventricle of the heart failing due to increased pressure in the lungs, often caused by chronic lung disease?

• A. Cor pulmonale
• B. Pulmonary embolism
• C. Aortic stenosis
• D. Hypertrophic cardiomyopathy

Correct answer: A

Rationale: The correct answer is Cor pulmonale, a condition where the right ventricle of the heart fails due to increased pressure in the lungs, commonly caused by chronic lung diseases like COPD. Pulmonary embolism (choice B) is a blockage in one of the pulmonary arteries in the lungs, usually caused by a blood clot. Aortic stenosis (choice C) is a narrowing of the aortic valve opening that restricts blood flow from the left ventricle to the aorta. Hypertrophic cardiomyopathy (choice D) is a genetic condition where the heart muscle becomes abnormally thick, making it harder for the heart to pump blood.

2. What is a device that delivers a fine spray of medication into the airways?

• A. Nebulizer
• B. Inhaler
• C. Oxygen concentrator
• D. Peak flow meter

Correct answer: A

Rationale: A nebulizer is a device that converts liquid medication into a fine mist, allowing it to be inhaled directly into the lungs. This makes it the correct answer to the question. Choice B, an inhaler, delivers medication in a different form - as a pressurized dose that needs to be inhaled. Choice C, an oxygen concentrator, is used to deliver oxygen to patients with breathing difficulties but does not deliver medication. Choice D, a peak flow meter, is used to measure how fast air can be blown out of the lungs and is not involved in delivering medication.

3. The nurse is teaching a client about the side effects of beta blockers. What is the most important side effect to monitor?

• A. Hypotension
• B. Bradycardia
• C. Hyperkalemia
• D. Tachycardia

Correct answer: A

Rationale: The most important side effect to monitor when a client is on beta blockers is hypotension. Beta blockers can cause a significant drop in blood pressure, especially at the initiation of therapy. Monitoring for hypotension is crucial to prevent complications such as dizziness, syncope, or falls. While bradycardia can also occur with beta blockers, hypotension takes precedence due to its immediate impact on perfusion. Hyperkalemia is not a common side effect of beta blockers. Tachycardia is actually a condition that beta blockers aim to treat, so it is not a side effect to monitor.

4. 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.

5. What condition involves the heart's electrical system malfunctioning, causing very fast heartbeats originating from the ventricles?

• A. Ventricular tachycardia
• B. Atrial fibrillation
• C. Supraventricular tachycardia
• D. Bradycardia

Correct answer: A

Rationale: Ventricular tachycardia is the correct answer. It is a condition characterized by the heart's electrical system malfunctioning, leading to very fast heartbeats originating from the ventricles. Ventricular tachycardia can be life-threatening as it may progress to ventricular fibrillation, causing cardiac arrest. Atrial fibrillation (choice B) involves rapid, irregular beating of the atria, not the ventricles. Supraventricular tachycardia (choice C) originates above the ventricles and does not involve ventricular malfunction. Bradycardia (choice D) is the opposite of tachycardia, characterized by an abnormally slow heart rate.
