Which condition refers to the heart being unable to pump sufficient blood to meet the body's needs?

  • A. Heart failure
  • B. Myocardial infarction
  • C. Cardiomyopathy
  • D. Pericarditis
Correct Answer: A

Rationale: The correct answer is A: Heart failure. This condition occurs when the heart is unable to pump enough blood to meet the body's needs. It can result from various factors such as high blood pressure, heart muscle damage, or heart valve disorders. In contrast, B (Myocardial infarction) refers to a heart attack caused by a blockage in the coronary arteries, C (Cardiomyopathy) is a disease of the heart muscle, and D (Pericarditis) is inflammation of the pericardium surrounding the heart. These conditions may affect the heart's function but do not specifically indicate the inability to pump sufficient blood like heart failure does.

What short term pharmacological approach is used after a client has a prosthetic heart valve replacement for 1 to 2 months postoperatively?

  • A. Anticoagulant therapy
  • B. Antibiotic therapy
  • C. Ace Inhibitor therapy
  • D. Beta Blocker therapy
Correct Answer: A

Rationale: Anticoagulant therapy prevents clot formation around the prosthetic valve, reducing the risk of complications.

What test measures the electrical activity of the heart over a 24- or 48-hour period?

  • A. Holter monitor
  • B. Electrocardiogram
  • C. Stress test
  • D. Chest X-ray
Correct Answer: A

Rationale: The correct answer is A: Holter monitor. This device records the electrical activity of the heart over an extended period, typically 24-48 hours, providing a more comprehensive assessment compared to a standard ECG (choice B). A stress test (choice C) evaluates the heart's response to physical exertion, not prolonged monitoring. A chest X-ray (choice D) is used to visualize the heart and lungs, but does not measure electrical activity. Therefore, the Holter monitor is the most appropriate test for continuous monitoring of heart activity over an extended period.

What is the pathophysiology of acute pulmonary edema?

  • A. Acute pulmonary edema occurs when there is a sudden increase in left ventricular end-diastolic pressure, leading to leakage of fluid into the alveoli and interstitial spaces in the lungs.
Correct Answer: C

Rationale: This fluid accumulation impairs gas exchange, causing severe respiratory distress.
