Nursing Elites

1. The client on enoxaparin (Lovenox) is scheduled for surgery. What is the nurse’s priority action?

• A. Hold the enoxaparin and notify the healthcare provider.
• B. Administer the enoxaparin as scheduled.
• C. Administer vitamin K before the surgery.
• D. Monitor the client’s INR and proceed with surgery.

Correct answer: A

Rationale: The correct answer is A: Hold the enoxaparin and notify the healthcare provider. Enoxaparin, being an anticoagulant, should be held before surgery to reduce the risk of excessive bleeding during the procedure. It is crucial to inform the healthcare provider to determine the appropriate management plan. Choice B is incorrect because administering enoxaparin before surgery can increase the risk of bleeding. Choice C is incorrect as vitamin K administration is not typically indicated in this situation. Choice D is incorrect because monitoring the client's INR and proceeding with surgery without addressing the enoxaparin can lead to significant bleeding complications.

2. What is a surgical procedure where a blood vessel is grafted to bypass a blocked coronary artery, improving blood flow to the heart muscle?

• A. Coronary artery bypass graft (CABG)
• B. Valve replacement
• C. Angioplasty
• D. Endarterectomy

Correct answer: A

Rationale: The correct answer is A: Coronary artery bypass graft (CABG). CABG involves grafting a blood vessel to bypass a blocked coronary artery, enhancing blood flow to the heart muscle. This procedure helps reduce the risk of heart attack by restoring proper blood circulation to the heart. Choice B, valve replacement, is a different surgical procedure that involves replacing damaged or dysfunctional heart valves. Choice C, angioplasty, is a minimally invasive procedure that uses a balloon to open narrowed or blocked blood vessels. Choice D, endarterectomy, is the surgical removal of plaque from the lining of an artery to improve blood flow.

3. The client on nitroglycerin complains of a headache. What is the most appropriate response by the nurse?

• A. Administer acetaminophen as prescribed for the headache.
• B. Hold the next dose of nitroglycerin.
• C. Discontinue the nitroglycerin immediately.
• D. Notify the healthcare provider immediately.

Correct answer: A

Rationale: The correct response is to administer acetaminophen as prescribed for the headache. Headaches are a common side effect of nitroglycerin due to vasodilation. Administering acetaminophen can help relieve the headache. Holding the next dose of nitroglycerin (Choice B) may not address the current headache, and discontinuing nitroglycerin immediately (Choice C) without healthcare provider guidance can be dangerous due to the potential for rebound hypertension. Notifying the healthcare provider immediately (Choice D) is not necessary for a common side effect like a headache, and the nurse can manage this symptom independently.

4. Which of the following is a chronic inflammatory disease of the airways that causes episodes of wheezing, breathlessness, chest tightness, and coughing?

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

Correct answer: A

Rationale: Asthma is the correct answer. It is a chronic inflammatory disease of the airways characterized by episodes of wheezing, breathlessness, chest tightness, and coughing. These symptoms are often triggered by allergens or exercise. Bronchitis is an inflammation of the bronchial tubes, but it is not typically chronic or involve the same triggers as asthma. Pneumonia is an infection of the lungs, and emphysema is a type of chronic obstructive pulmonary disease (COPD) often caused by smoking.

5. 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.
