Correct Answer: C

Rationale: In stage III of heart failure, the client displays symptoms such as dyspnea, fatigue, and other symptoms with ordinary physical activity, known as NYHA Class III. This is consistent with the client's presentation of dyspnea with activities of daily living, indicating a moderate level of heart failure. The need for the placement of an implantable defibrillator also suggests a more advanced stage of heart failure compared to stage I or II. Stage IV is characterized by severe symptoms at rest, which the client does not exhibit based on the information provided.

Correct Answer: C

Rationale: The epicardium is the outermost layer of the heart and is also known as the visceral layer of the serous pericardium. It is a thin layer that covers the surface of the heart and is composed of connective tissue and fat. The epicardium helps to protect the heart and provides a smooth outer surface for the heart to move within the pericardial cavity.

Correct Answer: B

Rationale: The correct answer is B. The statement "I need to use a soft toothbrush and an electric razor to avoid injuries" indicates that the client understands the importance of preventive measures to minimize bleeding risks while on anticoagulant therapy. Using a soft toothbrush and an electric razor can help prevent accidental cuts that may lead to bleeding complications. It shows the client's understanding of the need to take precautions to avoid potential harm while on long-term anticoagulant therapy. The other statements do not directly address safety measures to prevent bleeding complications associated with anticoagulant therapy.

Correct Answer: B

Rationale: When a client is in shock, their body is not able to regulate its temperature effectively. In this situation, using warm IV fluids helps prevent hypothermia by providing the body with fluids at a temperature closer to the body's normal core temperature. Hypothermia can worsen the condition of a client in shock by further compromising their body's ability to maintain adequate perfusion and oxygen delivery to tissues. Therefore, utilizing warm IV fluids is essential in the resuscitation of clients in shock to help maintain their core body temperature within a suitable range.

Correct Answer: B

Rationale: Ventricular fibrillation is the dysrhythmia most commonly associated with sudden cardiac death (SCD). Ventricular fibrillation is a rapid, chaotic, and disorganized electrical activity in the ventricles that leads to ineffective contraction. This dysrhythmia can quickly progress to hemodynamic collapse and ultimately cardiac arrest, resulting in sudden cardiac death if not promptly treated with defibrillation. Atrial flutter, paroxysmal supraventricular tachycardia, and junctional escape rhythm are not typically associated with as high a risk of sudden cardiac death as ventricular fibrillation.
