Nursing Elites

1. What is the term for a blood clot blocking an artery in the lungs, leading to symptoms like shortness of breath and chest pain?

• A. Pulmonary embolism
• B. Deep vein thrombosis (DVT)
• C. Myocardial infarction
• D. Pneumothorax

Correct answer: A

Rationale: The correct answer is A, pulmonary embolism. A pulmonary embolism occurs when a blood clot travels to the lungs and blocks an artery, causing symptoms like shortness of breath and chest pain. Choice B, deep vein thrombosis (DVT), involves a blood clot forming in a deep vein, usually in the legs. Choice C, myocardial infarction, refers to a heart attack due to blocked blood flow to the heart muscle. Choice D, pneumothorax, is a collapsed lung due to air leaking into the chest cavity.

2. The client is on amiodarone and reports blurred vision. What is the nurse’s best response?

• A. Reassure the client that this is a common side effect.
• B. Instruct the client to report this symptom to the healthcare provider immediately.
• C. Advise the client to stop taking the medication.
• D. Discontinue the amiodarone immediately.

Correct answer: B

Rationale: Blurred vision is a potential side effect of amiodarone. Instructing the client to report this symptom to the healthcare provider immediately is the most appropriate response. Choice A is incorrect because although blurred vision can be a common side effect of amiodarone, it should not be dismissed without further evaluation. Choice C is incorrect as advising the client to stop taking the medication without consulting the healthcare provider can be dangerous and is not the first course of action. Choice D is too drastic as discontinuing the medication should be done under the guidance of a healthcare provider after proper evaluation.

3. Which condition is characterized by fluid collection in the lungs, making it difficult to breathe?

• A. Pulmonary edema
• B. Pleurisy
• C. Pleural effusion
• D. Pneumothorax

Correct answer: A

Rationale: The correct answer is A, Pulmonary edema. Pulmonary edema is a condition where fluid accumulates in the air sacs of the lungs, causing breathing difficulty. Pleurisy (choice B) is inflammation of the pleura causing chest pain. Pleural effusion (choice C) is the buildup of excess fluid in the pleural space, the area between the layers of tissue that line the lungs and chest cavity. Pneumothorax (choice D) is the presence of air in the pleural space, which can cause a lung to collapse.

4. The client is on a beta blocker for hypertension. What should the nurse monitor for?

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

Correct answer: A

Rationale: Corrected Rationale: When a client is on a beta blocker for hypertension, the nurse should monitor for bradycardia. Beta blockers are known to decrease heart rate, which can lead to bradycardia. Tachycardia (choice B) is unlikely as beta blockers have the opposite effect. Hypertension (choice C) is the condition being treated, not a side effect of beta blockers. Respiratory distress (choice D) is not a common effect of beta blockers and is not typically monitored in clients taking beta blockers.

5. Which structure serves as the normal pacemaker of the heart?

• A. SA node
• B. AV node
• C. Purkinje fibers
• D. Atria

Correct answer: A

Rationale: The correct answer is the SA node. The sinoatrial (SA) node is known as the natural pacemaker of the heart as it generates electrical impulses initiating each heartbeat. The SA node is located in the right atrium and sets the rhythm and rate of the heartbeat. The AV node (choice B) is responsible for delaying the electrical impulse to allow the atria to contract before the ventricles. Purkinje fibers (choice C) are specialized cardiac fibers responsible for the rapid conduction of impulses to the myocardial cells, and the atria (choice D) are the upper chambers of the heart involved in receiving blood from the veins.
