Nursing Elites

1. The nurse is administering nitroglycerin IV to a client with chest pain. What is the most important parameter to monitor?

• A. Blood pressure
• B. Heart rate
• C. Oxygen saturation
• D. Respiratory rate

Correct answer: A

Rationale: The correct answer is A: Blood pressure. When administering nitroglycerin IV to a client with chest pain, monitoring blood pressure is crucial as nitroglycerin can cause significant hypotension. While heart rate, oxygen saturation, and respiratory rate are important parameters to assess, blood pressure takes precedence in this scenario due to the potential hypotensive effects of nitroglycerin.

2. The nurse is caring for a client on digoxin with a heart rate of 48 bpm. What is the nurse’s priority action?

• A. Hold the digoxin and notify the healthcare provider.
• B. Administer the digoxin as ordered.
• C. Administer atropine to increase the heart rate.
• D. Increase the dose of digoxin.

Correct answer: A

Rationale: In this scenario, the nurse's priority action should be to hold the digoxin and notify the healthcare provider. A heart rate of 48 bpm is low, and digoxin, being a medication that can further decrease the heart rate, should be withheld. Administering the digoxin as ordered (Choice B) would not be appropriate in this situation as it can exacerbate bradycardia. Atropine (Choice C) is not the initial treatment for this scenario; holding the digoxin is the first action. Increasing the dose of digoxin (Choice D) would be contraindicated due to the client's bradycardia. Therefore, the correct action is to hold the digoxin and inform the healthcare provider for further guidance.

3. Which chronic respiratory condition is characterized by the narrowing and inflammation of the airways, leading to difficulty breathing?

• A. Asthma
• B. COPD
• C. Bronchitis
• D. Pneumonia

Correct answer: A

Rationale: Asthma is the correct answer. It is a chronic respiratory condition where the airways become inflamed and narrowed, leading to episodes of wheezing, breathlessness, chest tightness, and coughing. Asthma is characterized by reversible airflow obstruction, differentiating it from COPD, which involves irreversible airflow limitation. Bronchitis is an inflammation of the bronchial tubes without the same reversible airflow obstruction seen in asthma. Pneumonia is an infection of the lung tissue and does not involve chronic inflammation and narrowing of the airways like asthma.

4. This is a procedure where a small mesh tube is inserted into an artery to keep it open and improve blood flow.

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

Correct answer: A

Rationale: Stent placement is a procedure where a small mesh tube (stent) is inserted into an artery to keep it open and improve blood flow, often following angioplasty.

5. 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.
