Nursing Elites

1. The client on amiodarone develops symptoms of hypothyroidism. What is the nurse’s best response?

• A. Notify the healthcare provider immediately.
• B. Reassure the client that this is a common side effect of amiodarone.
• C. Monitor the client’s thyroid function tests regularly.
• D. Discontinue the amiodarone immediately.

Correct answer: C

Rationale: When a client on amiodarone develops symptoms of hypothyroidism, the nurse's best response is to monitor the client's thyroid function tests regularly. Amiodarone can affect thyroid function, so monitoring is essential to assess the impact and adjust treatment if necessary. Notifying the healthcare provider immediately (Choice A) may be necessary in some cases but the priority is to monitor first. Reassuring the client (Choice B) is not sufficient as monitoring is crucial. Discontinuing amiodarone (Choice D) abruptly without healthcare provider guidance can lead to serious consequences.

2. Which medication relaxes the muscles around the airways, making it easier to breathe?

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

Correct answer: A

Rationale: The correct answer is A, Bronchodilator. Bronchodilators are medications that relax the muscles surrounding the airways, which helps to open them and makes breathing easier. Corticosteroids (choice B) work by reducing inflammation, antihistamines (choice C) are used to manage allergies, and mucolytics (choice D) help to break down and thin mucus in the airways.

3. This is a test that measures the oxygen saturation level in the blood, often used to assess respiratory function.

• A. Pulse oximetry
• B. Spirometry
• C. Arterial blood gas (ABG)
• D. Lung function test

Correct answer: A

Rationale: The correct answer is A, Pulse oximetry. Pulse oximetry is a non-invasive test that measures the oxygen saturation level in the blood, helping to assess respiratory and cardiovascular function. Choice B, Spirometry, measures lung function by assessing airflow and volume. Choice C, Arterial blood gas (ABG), evaluates the acidity, oxygen, and carbon dioxide levels in the blood. Choice D, Lung function test, is a broad term that may include various tests to assess lung health, but specifically measuring oxygen saturation is done through pulse oximetry.

4. What does the PR interval measure?

• A. Time it takes for the electrical impulse to travel from the atria to the ventricles
• B. Measurement of ventricular depolarization
• C. Duration of ventricular repolarization
• D. Segment representing the time between ventricular depolarization and repolarization

Correct answer: A

Rationale: The PR interval measures the time it takes for the electrical impulse to travel from the atria to the ventricles. It is crucial in diagnosing heart rhythm disorders, as abnormalities in this interval can indicate conduction abnormalities between the atria and ventricles. Choices B, C, and D are incorrect. The QRS complex represents ventricular depolarization, the QT interval represents the duration of ventricular repolarization, and the ST segment represents the time between ventricular depolarization and repolarization.

5. Which condition is characterized by chronic inflammation of the airways resulting in excess mucus production, leading to frequent coughing and breathing difficulties?

• A. Chronic bronchitis
• B. Asthma
• C. Pneumonia
• D. COPD

Correct answer: A

Rationale: The correct answer is A, Chronic bronchitis. Chronic bronchitis involves long-term inflammation of the bronchi, leading to excessive mucus production, frequent coughing, and breathing difficulties. Asthma (B) is characterized by reversible airway obstruction and bronchospasms. Pneumonia (C) is an infection of the lungs caused by bacteria, viruses, or fungi. COPD (D) is a term used to describe chronic lung diseases that cause airflow blockage and breathing-related problems.
