The client has atrial fibrillation. The treatment of choice to convert to normal sinus rhythm is what?

Correct Answer: B

Rationale: The correct answer is B: Cardioversion. Cardioversion is the treatment of choice to convert atrial fibrillation to normal sinus rhythm quickly and effectively. It involves delivering an electric shock to the heart to restore its normal rhythm. Digoxin (choice A) is not used for acute conversion but for rate control. Metoprolol (choice C) and Verapamil (choice D) are used for rate control and not for rhythm conversion. Therefore, Cardioversion is the most appropriate choice in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Heparin prevents the development of new clots in the coronary arteries. Heparin is an anticoagulant that works by inhibiting the formation of blood clots. In the case of NSTEMI, there is a risk of clot formation in the coronary arteries, which can worsen the condition. By preventing the development of new clots, heparin helps maintain blood flow to the heart muscle. Choice A is incorrect because heparin actually inhibits platelet aggregation, preventing clot formation. Choice B is incorrect as heparin does not directly affect the size of the plaque in the arteries. Choice D is incorrect because heparin does not actively dissolve existing blood clots, but rather prevents new clots from forming.

Correct Answer: B

Rationale: The correct answer is B because it provides accurate information about the energy expenditure during sexual activity, which can be a concern for patients recovering from an AMI. Climbing two flights of stairs is a useful reference point for patients to gauge their readiness for physical exertion. Choice A is incorrect as it oversimplifies the potential risks and complications associated with resuming sexual activity post-AMI. Choice C is incorrect as it suggests that the doctor will provide specific guidelines without addressing the patient's concerns in the moment. Choice D is incorrect as it focuses solely on emotional intimacy rather than addressing the patient's question about physical activity.

Correct Answer: C

Rationale: The correct answer is C: No change in the patient's reported level of chest pain. This is the most important information to communicate because it indicates a lack of improvement in the patient's condition despite thrombolytic therapy. This suggests a potential complication or treatment failure that needs immediate attention. A: An increase in troponin levels from baseline may indicate ongoing myocardial damage but may not be as urgent as persistent chest pain. B: A large bruise at the IV site is a common side effect of thrombolytic therapy and can usually be managed without immediate intervention. D: A decrease in ST-segment elevation on the ECG is a positive sign of reperfusion but may not be as urgent as persistent chest pain.

Correct Answer: A

Rationale: The correct answer is A: stasis ulcer. Peripheral vascular disease causes poor blood circulation in the extremities, leading to tissue damage and ulcers, particularly in the lower legs and feet. Stasis ulcers are a common complication due to decreased blood flow. Pressure ulcers (B) are caused by prolonged pressure on the skin, not related to vascular disease. Gastric ulcer (C) and duodenal ulcer (D) are typically associated with gastrointestinal issues, such as Helicobacter pylori infection or nonsteroidal anti-inflammatory drug use, and are not directly related to peripheral vascular disease.
