Nokea
Which of the following symptoms is observed in the client with right-sided heart failure?
- A. Dependent pitting edema
- B. Exertional dyspnea
- C. Orthopnea
- D. Hemoptysis
Correct Answer: A
Rationale: Right-sided heart failure leads to fluid retention, causing dependent pitting edema.

What procedure involves using a balloon to open a narrowed or blocked blood vessel, often followed by the placement of a stent?
- A. Angioplasty
- B. Valve replacement
- C. Coronary artery bypass graft (CABG)
- D. Endarterectomy
Correct Answer: A
Rationale: The correct answer is A: Angioplasty. Angioplasty involves using a balloon to open a narrowed or blocked blood vessel, followed by the placement of a stent to keep the vessel open. This procedure is commonly used to treat conditions like coronary artery disease. Valve replacement (B) involves replacing damaged heart valves, CABG (C) involves bypassing blocked coronary arteries using grafts, and endarterectomy (D) involves removing plaque from arteries, but none of these procedures specifically involve using a balloon and stent to open a narrowed or blocked blood vessel.
What test uses sound waves to create images of the heart and assess its structure and function?
- A. Echocardiogram
- B. MRI
- C. CT scan
- D. X-ray
Correct Answer: A
Rationale: The correct answer is A: Echocardiogram. An echocardiogram uses sound waves to create images of the heart, providing detailed information about its structure and function. It is a non-invasive and safe test commonly used to diagnose various heart conditions. MRI (B) uses magnetic fields and radio waves, CT scan (C) uses X-rays, and X-ray (D) uses electromagnetic radiation, but none of these tests specifically utilize sound waves for imaging the heart.
Priority Decision: A patient is hospitalized after a successful resuscitation of an episode of sudden cardiac death (SCD). During the care of the patient, what nursing intervention is most important?
- A. Continuous ECG monitoring
- B. Auscultation of the carotid arteries
- C. Frequent assessment of heart sounds
- D. Monitoring of airway status and respiratory patterns
Correct Answer: A
Rationale: Continuous monitoring detects dysrhythmias.
Identify the three layers of the heart:
- A. Endocardium, Myocardium, Epicardium
- B. Epicardium, Pericardium, Endocardium
- C. Myocardium, Endocardium, Pericardium
- D. Pericardium, Myocardium, Endocardium
Correct Answer: A
Rationale: Rationale:
1. Endocardium: Innermost layer lining the heart chambers.
2. Myocardium: Middle layer composed of cardiac muscle tissue.
3. Epicardium: Outermost layer forming the visceral pericardium.
Therefore, the correct answer is A.
Summary:
B is incorrect as it includes Pericardium instead of Myocardium.
C is incorrect as it switches the positions of Myocardium and Epicardium.
D is incorrect as it has the layers listed in the wrong order and includes Pericardium as the innermost layer.
For what reason might the nurse be given an order to administer milrinone (Primacor)?
- A. For congestive heart failure
- B. For hypertension
- C. For cardiac arrhythmias
- D. For bradycardia
Correct Answer: A
Rationale: The correct answer is A: For congestive heart failure. Milrinone is a phosphodiesterase inhibitor used to improve cardiac output in patients with severe heart failure. It works by increasing the force of heart contractions. Therefore, it is specifically indicated for congestive heart failure to help improve cardiac function. Choices B, C, and D are incorrect because milrinone is not typically used for hypertension, cardiac arrhythmias, or bradycardia. It is important to understand the specific indications and mechanisms of action of medications to determine the appropriate use in clinical practice.
