Nursing Elites

1. The healthcare provider is administering IV nitroglycerin to a patient for chest pain. What is the most critical parameter to monitor?

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

Correct answer: B

Rationale: The correct answer is 'Blood pressure.' Nitroglycerin is a vasodilator that can cause a rapid drop in blood pressure, leading to hypotension. Monitoring the blood pressure is crucial to prevent potential complications such as hypotension-induced dizziness, syncope, or organ hypoperfusion. While heart rate, oxygen saturation, and respiratory rate are important parameters to monitor in a clinical setting, the immediate concern with IV nitroglycerin administration is the risk of hypotension, making blood pressure the most critical parameter to assess.

2. The nurse is monitoring a client on dobutamine. What adverse effect should the nurse watch for?

• A. Tachycardia
• B. Bradycardia
• C. Hypertension
• D. Respiratory distress

Correct answer: A

Rationale: The correct answer is A: Tachycardia. Dobutamine is a medication that stimulates beta-1 adrenergic receptors in the heart, leading to increased heart rate. Therefore, tachycardia is a common adverse effect that the nurse should monitor for. Choices B, C, and D are incorrect because dobutamine typically does not cause bradycardia, hypertension, or respiratory distress as its primary adverse effects.

3. What type of medication is used to relax the muscles around the airways and improve breathing in conditions like asthma and COPD?

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

Correct answer: A

Rationale: Bronchodilators are medications that relax the muscles around the airways, improving airflow and making breathing easier for patients with asthma or COPD. Corticosteroids are anti-inflammatory drugs used to reduce airway inflammation, while mucolytics help in thinning and clearing mucus. Antihistamines are used to treat allergies and not specifically to improve breathing in conditions like asthma or COPD.

4. What is a condition where the heart beats with an irregular or abnormal rhythm?

• A. Arrhythmia
• B. Hypertension
• C. Tachycardia
• D. Bradycardia

Correct answer: A

Rationale: Arrhythmia is the correct answer because it refers to an irregular or abnormal heart rhythm, which can cause the heart to beat too fast, too slow, or erratically. Hypertension (choice B) is high blood pressure and not directly related to irregular heart rhythm. Tachycardia (choice C) is a condition where the heart beats too quickly, not necessarily irregularly. Bradycardia (choice D) is a condition where the heart beats too slowly, not necessarily irregularly. Therefore, only arrhythmia (choice A) fits the description provided in the question.

5. What is a chronic condition where the bronchial tubes in the lungs become inflamed and narrowed, often caused by smoking?

• A. Chronic bronchitis
• B. Emphysema
• C. Asthma
• D. Tuberculosis

Correct answer: A

Rationale: Chronic bronchitis is the correct answer because it is a long-term condition characterized by inflammation and narrowing of the bronchial tubes in the lungs, commonly triggered by smoking. Emphysema involves damage to the air sacs in the lungs, not specifically the bronchial tubes. Asthma is a condition of reversible airway obstruction usually due to allergies or other triggers, not solely smoking. Tuberculosis is a bacterial infection that primarily affects the lungs but is not directly related to inflammation and narrowing of the bronchial tubes.
