A patient presents with chest pain at rest, unrelated to exertion, and not relieved by nitroglycerin. An electrocardiogram (ECG) shows ST-segment depression. Which cardiovascular disorder is most likely responsible for these symptoms?

Correct Answer: B

Rationale: Unstable angina is characterized by chest pain at rest, which is not relieved by nitroglycerin. The ECG findings in unstable angina typically show ST-segment depression or T-wave inversion. It is considered a medical emergency as it can progress to a myocardial infarction. Stable angina, on the other hand, is chest pain or discomfort that occurs with exertion and is relieved by rest or medications like nitroglycerin. Acute myocardial infarction would typically present with ST-segment elevation on ECG, while Prinzmetal's angina is characterized by transient ST-segment elevation due to coronary artery vasospasm.

Correct Answer: C

Rationale: Collaborating with interdisciplinary team members to develop a comprehensive care plan demonstrates effective care coordination. In complex healthcare situations, involving various healthcare providers such as physicians, specialists, therapists, social workers, and others is crucial to ensure that all aspects of the patient's care are addressed holistically. By working together, healthcare professionals can share information, expertise, and insights to develop a well-rounded care plan that considers all aspects of the patient's needs. This collaborative approach helps promote better outcomes for the patient and enhances overall care coordination. It also helps to ensure that the patient's preferences and values are taken into account when developing the care plan.

Correct Answer: C

Rationale: In this situation, the most appropriate response for the palliative nurse is to validate the patient's feelings of guilt and offer support to address their concerns. It is important to acknowledge the patient's emotions and help them navigate through their guilt in a compassionate and understanding manner. By validating their feelings, the nurse can create a safe space for the patient to express their concerns and work towards finding solutions to alleviate their guilt. This approach fosters trust and a therapeutic relationship between the patient and the nurse, ultimately promoting emotional well-being and facilitating open communication.

Correct Answer: A

Rationale: The response indicating Annie's present condition would be option A. This is because the symptoms mentioned in option A, such as experiencing vertigo, nausea, and nystagmus when sitting, point towards a vestibular disorder. These are symptoms commonly associated with conditions like Meniere's disease or vestibular neuritis, which can cause balance issues and feelings of dizziness. These symptoms are more indicative of Annie's current health status compared to the other options which focus on past or unrelated issues, such as ear pain during travel or impaired hearing since birth. The information provided in option A gives a more direct insight into Annie's present condition, making it the most appropriate response.

Correct Answer: C

Rationale: In pneumothorax, air enters the normally negative pressure space between the lung and chest wall, leading to loss of negative intra-pleural pressure. However, this loss of negative pressure typically does not directly result in lung collapse. Instead, the accumulation of air in the pleural space can lead to a pressure imbalance, causing the lung to collapse partially or completely, which is known as atelectasis. Therefore, it is more accurate to state that the loss of negative intra-pleural pressure can result in lung collapse due to the presence of air in the pleural space, rather than the loss of negative pressure itself causing the collapse.

Correct Answer: D

Rationale: Speaking up on behalf of the patient to ensure their needs are met is a key action that demonstrates advocacy by the nurse. Advocacy involves actively supporting and safeguarding the rights of the patient, ensuring that their best interests are being considered within the healthcare system. This may include advocating for appropriate treatment, services, resources, or respect for the patient's autonomy and decision-making. By speaking up for the patient, the nurse is acting as their voice and championing their well-being.

Correct Answer: B

Rationale: Providing means to evaluate services is the most appropriate measure to ensure patient satisfaction with the delivery of health services. This can be done through patient surveys, feedback forms, or other evaluation methods. By systematically collecting and analyzing feedback from patients, healthcare providers can assess the quality of their services, identify areas for improvement, and address any concerns or issues raised by patients. This proactive approach allows for continuous monitoring and improvement of the healthcare services provided, leading to enhanced patient satisfaction and overall quality of care.

Correct Answer: D

Rationale: The symptoms described by the patient indicate a potential transfusion reaction, such as a hemolytic reaction or allergic reaction. The immediate action the nurse should take in such a situation is to stop the infusion of the packed red blood cells. This will help prevent further complications and ensure the safety of the patient. After stopping the infusion, the nurse should assess the patient's condition, monitor vital signs, and inform the healthcare team, including the physician, regarding the situation. Once the patient is stable, further investigations can be conducted to determine the cause of the reaction.

Correct Answer: B

Rationale: Endometriosis is a chronic gynecologic condition characterized by the presence of endometrial-like tissue outside the uterus, commonly on structures within the pelvis. The classic symptoms of endometriosis include cyclic pelvic pain, dysmenorrhea (painful periods), and infertility. On pelvic examination, tender nodules or masses may be palpated along the uterosacral ligaments. These nodules are often referred to as "endometriotic implants" or "chocolate cysts." Endometriosis can cause inflammation, scarring, and adhesions in the pelvis, leading to symptoms such as pain and infertility. Polycystic ovary syndrome (PCOS) is characterized by ovarian dysfunction and hormonal imbalances, often leading to irregular periods and symptoms related to excess androgens. Adenomyosis is the presence of endometrial tissue within the myometrium of the uterus, leading
