Nursing Elites

1. 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.

2. What is a condition where the blood supply to the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients?

• A. Stroke
• B. Transient ischemic attack (TIA)
• C. Myocardial infarction
• D. Angina

Correct answer: A

Rationale: A stroke is the correct answer. A stroke occurs when the blood supply to part of the brain is interrupted or reduced, leading to a lack of oxygen and nutrients to the brain tissue, causing brain damage. Choices B, C, and D are incorrect because a transient ischemic attack (TIA) is a temporary blockage of blood flow to the brain with no lasting damage, myocardial infarction is a heart attack due to blockage of blood flow to the heart muscle, and angina is chest pain caused by reduced blood flow to the heart.

3. 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.

4. What condition involves the heart's electrical system malfunctioning, causing very fast heartbeats originating from the ventricles?

• A. Ventricular tachycardia
• B. Atrial fibrillation
• C. Supraventricular tachycardia
• D. Bradycardia

Correct answer: A

Rationale: Ventricular tachycardia is the correct answer. It is a condition characterized by the heart's electrical system malfunctioning, leading to very fast heartbeats originating from the ventricles. Ventricular tachycardia can be life-threatening as it may progress to ventricular fibrillation, causing cardiac arrest. Atrial fibrillation (choice B) involves rapid, irregular beating of the atria, not the ventricles. Supraventricular tachycardia (choice C) originates above the ventricles and does not involve ventricular malfunction. Bradycardia (choice D) is the opposite of tachycardia, characterized by an abnormally slow heart rate.

5. The client asks about side effects of taking digoxin. How does the nurse respond?

• A. Anorexia can be a side effect of digoxin.
• B. Tachycardia can be a side effect of digoxin.
• C. Constipation can be a side effect of digoxin.
• D. Urinary retention can be a side effect of digoxin.

Correct answer: A

Rationale: The correct answer is A: 'Anorexia can be a side effect of digoxin.' Anorexia, nausea, vomiting, and diarrhea are commonly known side effects of digoxin. Choice B, 'Tachycardia can be a side effect of digoxin,' is incorrect as digoxin is used to treat tachycardia, not cause it. Choice C, 'Constipation can be a side effect of digoxin,' is incorrect as constipation is not a typical side effect of digoxin. Choice D, 'Urinary retention can be a side effect of digoxin,' is also incorrect as urinary retention is not a common side effect associated with digoxin use.
