A nurse is required to monitor a client with dysrhythmia during the administration of isoproterenol. Which of the following nursing interventions will help to determine the drug response?
- A. Monitor vital signs.
- B. Closely monitor the pulse rate.
- C. Monitor blood pressure.
- D. Monitor fluid intake and output.
Correct Answer: D
Rationale: Monitoring fluid balance helps assess volume status and its impact on heart rate and rhythm during isoproterenol administration.

What is a condition where the heart is unable to pump blood effectively, leading to a buildup of fluid in the lungs and other parts of the body?
- A. Heart failure
- B. Cardiomyopathy
- C. Myocardial infarction
- D. Pulmonary edema
Correct Answer: A
Rationale: Rationale for Correct Answer (A): Heart failure is the correct answer because it is a condition where the heart is unable to pump blood effectively, leading to fluid buildup in the lungs and other parts of the body. This occurs due to the heart's inability to adequately circulate blood, causing congestion and fluid retention. Symptoms include shortness of breath, fatigue, and swelling. Treatment aims to improve heart function and manage symptoms.
Summary of Incorrect Choices:
B (Cardiomyopathy): Cardiomyopathy is a disease of the heart muscle, which can lead to heart failure, but it is not the specific condition described in the question.
C (Myocardial infarction): Myocardial infarction, commonly known as a heart attack, results from a blockage in a coronary artery causing damage to the heart muscle, but it does not directly lead to fluid buildup in the lungs and body.
D (Pulmonary edema): Pulmonary edema is a condition characterized by fluid
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). This surgical procedure involves grafting a blood vessel to bypass a blocked coronary artery, improving blood flow to the heart muscle. It is used to treat severe coronary artery disease. Valve replacement (B) is a surgery to replace heart valves, not to bypass blocked arteries. Angioplasty (C) involves inserting a balloon to widen a narrowed artery, not bypassing it. Endarterectomy (D) is a procedure to remove plaque from an artery, not bypassing a blocked coronary artery.
What procedure is used to visualize the airways and diagnose lung disease?
- A. Bronchoscopy
- B. Thoracentesis
- C. Pulmonary function test
- D. Chest X-ray
Correct Answer: A
Rationale: The correct answer is A: Bronchoscopy. Bronchoscopy is a procedure where a thin, flexible tube with a camera is inserted into the airways to visualize and diagnose lung diseases directly. It allows for direct visualization of the airways, collection of samples for biopsy, and removal of obstructions. Thoracentesis (B) is a procedure to remove fluid from the pleural space, not for visualizing airways. Pulmonary function test (C) measures lung function but doesn't directly visualize airways. Chest X-ray (D) provides an image of the lungs but doesn't allow for direct visualization or diagnosis of airway diseases.
Which serum lipid elevation, along with elevated LDL, is strongly associated with CAD?
- A. Apolipoproteins
- B. Fasting triglycerides
- C. Total serum cholesterol
- D. High-density lipoprotein (HDL)
Correct Answer: B
Rationale: Elevated triglycerides increase CAD risk.
The nurse is preparing to administer a beta blocker to a client with hypertension. What is the priority assessment?
- A. Check the client's heart rate.
- B. Check the client's blood pressure.
- C. Check the client's respiratory rate.
- D. Check the client's temperature.
Correct Answer: B
Rationale: The correct answer is B: Check the client's blood pressure. When administering a beta blocker to a client with hypertension, the priority assessment is to check the client's blood pressure. Beta blockers lower blood pressure, so monitoring it before administration helps ensure it is within the safe range. Checking the client's heart rate (choice A) is important but not the priority in this scenario. Respiratory rate (choice C) and temperature (choice D) are not directly related to the administration of beta blockers for hypertension.
