Correct Answer: A

Rationale: The nurse in the practice of her profession is guided by a code of ethics, which outlines the moral duties and professional responsibilities of nurses. The code of ethics provides a framework for ethical decision-making and sets standards for professional behavior within the nursing profession. Nurses are expected to adhere to the principles of the code of ethics in order to promote the well-being and safety of their patients, maintain professional integrity, and uphold the values of nursing practice.

Correct Answer: D

Rationale: Advocacy is the ethical principle that the nurse is responsible for providing all patients with caring attention and information, despite the reaction of the patient. Advocacy involves supporting and speaking up for the patient's best interests, ensuring they receive the care and information they need to make informed decisions about their health and well-being. Providing caring attention and information is essential in advocating for the patient's autonomy and well-being, even if the patient may not initially appreciate or react positively to these efforts.

Correct Answer: C

Rationale: The theory of Nursing as Caring was developed by Dr. Jean Watson, a renowned nurse theorist and professor. Watson's Theory of Human Caring focuses on the importance of the nurse-patient relationship, emphasizing the significance of caring in promoting healing and promoting holistic well-being. This theory emphasizes the humanistic aspects of nursing care and highlights the nurse's role in fostering a caring environment that encompasses physical, emotional, social, and spiritual dimensions. Watson's theory emphasizes the importance of empathy, compassion, and authentic presence in nursing practice, making it a valuable framework for guiding nursing care and promoting healing outcomes.

Correct Answer: A

Rationale: In a patient with acute myocardial infarction (MI) presenting with ST-segment elevation on ECG, the healthcare team should prioritize performing emergent coronary angiography for revascularization. This intervention, also known as primary percutaneous coronary intervention (PCI), involves opening up the blocked coronary artery responsible for the MI. Timely reperfusion of the affected artery is crucial in reducing myocardial damage and improving outcomes in acute MI patients. PCI is considered the preferred method for revascularization in patients with ST-segment elevation MI, as it has been shown to be more effective and associated with better outcomes compared to fibrinolytic therapy.

Correct Answer: D

Rationale: Ensuring the availability of emergency equipment and resuscitation medications is crucial to prioritize patient safety during a transesophageal echocardiogram (TEE) procedure. TEE involves inserting a specialized probe (transducer) into the esophagus to obtain detailed images of the heart. While complications during TEE are rare, they can include adverse reactions to sedation, esophageal injury, arrhythmias, or other cardiac events. By having emergency equipment and resuscitation medications readily available, the healthcare team can respond promptly to any unforeseen complications or emergencies that may arise during the procedure, ensuring optimal patient safety. Placing the patient in a supine position, providing sedation, and advising the patient to fast before the procedure are important aspects of the TEE process; however, ensuring emergency preparedness takes precedence in prioritizing patient safety during the procedure.
