1. The client on furosemide (Lasix) is at risk for which electrolyte imbalance?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hyponatremia
• D. Hypernatremia

Correct answer: B

Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. This electrolyte imbalance is a significant risk associated with diuretic use. Choices A, C, and D are incorrect. Hyperkalemia (choice A) is not typically associated with furosemide use. Hyponatremia (choice C) and hypernatremia (choice D) are related to sodium levels, not potassium levels affected by furosemide.

2. What is a condition where the heart beats too slowly, reducing the amount of blood pumped to the body?

• A. Bradycardia
• B. Tachycardia
• C. Atrial fibrillation
• D. Ventricular fibrillation

Correct answer: A

Rationale: Bradycardia is the correct answer. It is a condition characterized by a slow heart rate, which reduces the amount of blood pumped to the body. This can lead to symptoms like fatigue and dizziness. Choice B, Tachycardia, is the opposite condition where the heart beats too fast. Choices C and D, Atrial fibrillation and Ventricular fibrillation, refer to irregular and potentially life-threatening rapid heart rhythms involving the atria and ventricles respectively, not a slow heart rate.

3. Which of the following conditions is characterized by inflammation of the heart muscle, often due to a viral infection, leading to impaired heart function?

• A. Myocarditis
• B. Endocarditis
• C. Pericarditis
• D. Cardiomyopathy

Correct answer: A

Rationale: The correct answer is A, Myocarditis. Myocarditis is an inflammation of the heart muscle, typically caused by a viral infection. It can impair the heart's ability to pump blood efficiently, potentially leading to other complications. Endocarditis (choice B) is an inflammation of the inner lining of the heart chambers and valves. Pericarditis (choice C) is inflammation of the pericardium, the outer lining of the heart. Cardiomyopathy (choice D) is a disease of the heart muscle that affects the heart's ability to pump blood.

4. Which chronic respiratory condition is characterized by the narrowing and inflammation of the airways, leading to difficulty breathing?

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

Correct answer: A

Rationale: Asthma is the correct answer. It is a chronic respiratory condition where the airways become inflamed and narrowed, leading to episodes of wheezing, breathlessness, chest tightness, and coughing. Asthma is characterized by reversible airflow obstruction, differentiating it from COPD, which involves irreversible airflow limitation. Bronchitis is an inflammation of the bronchial tubes without the same reversible airflow obstruction seen in asthma. Pneumonia is an infection of the lung tissue and does not involve chronic inflammation and narrowing of the airways like asthma.

5. The nurse is administering nitroglycerin IV to a client with chest pain. What is the most important parameter to monitor?

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

Correct answer: A

Rationale: The correct answer is A: Blood pressure. When administering nitroglycerin IV to a client with chest pain, monitoring blood pressure is crucial as nitroglycerin can cause significant hypotension. While heart rate, oxygen saturation, and respiratory rate are important parameters to assess, blood pressure takes precedence in this scenario due to the potential hypotensive effects of nitroglycerin.
