Nursing Elites

1. Which condition is characterized by the lungs becoming scarred and stiff, leading to difficulty breathing and inadequate oxygen intake into the bloodstream?

• A. Pulmonary fibrosis
• B. Cystic fibrosis
• C. COPD
• D. Tuberculosis

Correct answer: A

Rationale: The correct answer is A, Pulmonary fibrosis. Pulmonary fibrosis is a lung disease where lung tissue is damaged and scarred, resulting in breathing difficulties and decreased oxygen transfer into the bloodstream. Cystic fibrosis (B) is a genetic disorder primarily affecting the lungs and digestive system, not causing lung scarring. COPD (C) includes conditions like chronic bronchitis and emphysema but doesn't specifically involve lung scarring. Tuberculosis (D) is a bacterial infection that primarily affects the lungs but doesn't cause lung tissue scarring and stiffness as seen in pulmonary fibrosis.

2. The nurse is giving a client an IV bolus of heparin. What is the most important nursing action?

• A. Monitor the client's heart rate.
• B. Check the client's blood pressure.
• C. Check for signs of bleeding.
• D. Monitor the client's respiratory rate.

Correct answer: A

Rationale: When administering an IV bolus of heparin, the most important nursing action is to monitor the client's heart rate. Heparin can cause bradycardia as a side effect, making it crucial to assess the heart rate for any abnormalities. Checking the blood pressure (Choice B) is important but not as critical as monitoring the heart rate. While checking for signs of bleeding (Choice C) is essential, it is not the most crucial action when administering heparin. Monitoring the respiratory rate (Choice D) is also important but not as directly related to the potential side effects of heparin as monitoring the heart rate.

3. The client has a prescription for sublingual nitroglycerin. What is the nurse's instruction for how to take this medication during an episode of chest pain?

• A. Take one tablet every 5 minutes, up to three tablets.
• B. Take one tablet every hour until the pain subsides.
• C. Take two tablets immediately if chest pain occurs.
• D. Take one tablet with a full glass of water.

Correct answer: A

Rationale: The correct answer is A. The standard instruction for sublingual nitroglycerin during an episode of chest pain is to take one tablet every 5 minutes, up to three tablets. If the pain persists after taking three tablets, the client should seek emergency help. Choice B is incorrect because taking one tablet every hour is not the appropriate dosing for acute chest pain. Choice C is incorrect as taking two tablets immediately is not in line with the recommended dosing instructions. Choice D is incorrect because sublingual nitroglycerin should be placed under the tongue, not swallowed with water.

4. 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.

5. The client on a beta blocker has a blood pressure of 88/58 mm Hg. What is the nurse’s priority action?

• A. Hold the beta blocker and notify the healthcare provider.
• B. Administer the beta blocker as ordered.
• C. Increase the dose of the beta blocker.
• D. Continue to monitor the client and reassess in 30 minutes.

Correct answer: A

Rationale: The correct action for the nurse to take when a client on a beta blocker presents with a blood pressure of 88/58 mm Hg is to hold the beta blocker and notify the healthcare provider. Beta blockers can further decrease blood pressure, which is already low in this case. Administering the beta blocker as ordered (Choice B) would exacerbate the hypotension. Increasing the dose of the beta blocker (Choice C) would be inappropriate and unsafe given the low blood pressure. Continuing to monitor the client and reassessing in 30 minutes (Choice D) could lead to a delay in necessary intervention. Therefore, the priority is to hold the medication and seek guidance from the healthcare provider.
