A patient presents with chest pain that worsens with exertion and improves with rest. An electrocardiogram (ECG) shows ST-segment depression. Which cardiovascular disorder is most likely responsible for these symptoms?

Correct Answer: A

Rationale: The patient is presenting with chest pain that worsens with exertion and improves with rest, which is characteristic of stable angina. Additionally, ST-segment depression on ECG is a common finding in patients with stable angina. Stable angina is typically caused by coronary artery disease, which leads to partial obstruction of the coronary arteries resulting in inadequate blood flow to the heart muscle during periods of increased demand (such as exertion). The chest pain is usually predictable and reproducible, occurring with similar intensity and duration during episodes of exertion. Rest or nitroglycerin can help relieve the symptoms by increasing coronary blood flow. It is important to differentiate stable angina from unstable angina and acute myocardial infarction, which have different management and prognostic implications.

Correct Answer: B

Rationale: Maternal anxiety can contribute to a prolonged latent phase during labor. Stress and anxiety can trigger the release of stress hormones such as adrenaline, which can interfere with the production of oxytocin, the hormone responsible for initiating contractions. This can result in irregular and ineffective contractions, leading to a prolonged latent phase. It is important for the nurse to assess the woman's anxiety levels and provide reassurance and support to help facilitate the progression of labor.

Correct Answer: A

Rationale: Research at work is an example of self-directed learning activity because it involves taking the initiative to seek out information, learn new skills, and solve problems independently within a workplace setting. This type of learning requires self-motivation, self-discipline, and autonomy to set goals, gather resources, and develop knowledge or expertise in a specific area. Individuals engage in research at work to enhance their professional growth, expand their skill set, or address challenges encountered in their job responsibilities. It is a proactive approach to learning where individuals take charge of their own development and continuously strive to improve their performance.

Correct Answer: B

Rationale: The nurse's priority action when noticing an abnormal heart rhythm on the patient's cardiac monitor during surgery is to assess the patient's vital signs and symptoms. This is important because the nurse needs to gather more information about the patient's condition to determine the significance of the abnormal rhythm and the potential impact on the patient's health. By assessing the vital signs and symptoms, the nurse can obtain a more complete picture of the situation and make informed decisions about the next steps in caring for the patient. Once the assessment is done, appropriate actions such as administering medication or notifying the anesthesiologist can be taken based on the findings.

Correct Answer: C

Rationale: When working with Sandro, who is taking an MAOI and needs to be educated on avoiding foods with tyramine, the nursing diagnosis commonly used would be "impaired social interaction." This nursing diagnosis focuses on the client's difficulty in establishing or maintaining meaningful relationships with others. In this case, Sandro's dietary restrictions due to his medication may cause challenges in social situations, leading to potential feelings of isolation or inability to engage in social activities involving food. By identifying impaired social interaction as a nursing diagnosis, the nurse can address these issues and support Sandro in maintaining social connections while adhering to his dietary requirements.

Correct Answer: C

Rationale: When caring for patients with hyperbilirubinemia, the nursing care plan should focus on informing the significant others, preventing injury, and preventing complications. The primary goal in managing hyperbilirubinemia is to prevent complications associated with high bilirubin levels, such as kernicterus. Therefore, maintaining physiological homeostasis with bilirubin levels increasing would not be appropriate and should not be the focus of the nursing care plan. It is crucial to monitor and manage bilirubin levels to prevent adverse outcomes rather than allowing them to increase.

Correct Answer: A

Rationale: Prolonged rupture of membranes (>24 hours) increases the risk of intrauterine infection for both the mother and the fetus. When the amniotic sac has been ruptured for an extended period, there is a higher likelihood of bacteria entering the uterus, leading to chorioamnionitis (inflammation of the fetal membranes due to infection). Intrauterine infection can be dangerous for both the mother and fetus, potentially causing sepsis, preterm labor, and other complications. Therefore, it is crucial for the nurse to assess for signs and symptoms of infection in both the mother and fetus when managing a woman in active labor with prolonged rupture of membranes.

Correct Answer: A

Rationale: The primary indicator that Nurse Mary observes FIDELITY in the practice of her profession is that she faithfully promotes health and prevents disease. Fidelity in nursing practice refers to being faithful, loyal, and committed to providing the best care and services to patients. By faithfully promoting health and preventing disease, Nurse Mary demonstrates her dedication to her profession, her patients, and the community she serves. This commitment includes following evidence-based practices, upholding ethical standards, being honest and trustworthy, and ensuring the well-being of those under her care. Ultimately, fidelity in nursing practice builds trust and confidence among patients, families, and colleagues, leading to better health outcomes and a stronger healthcare system.

Correct Answer: C

Rationale: When selecting participants for a qualitative research study, it is important to choose individuals who are able to articulate and reflect on the phenomenon being studied. This is crucial for gathering in-depth and rich data that can provide valuable insights for the study. Participants who can express their experiences, thoughts, and feelings clearly will allow the researcher to delve deeper into the research objectives and gain a more comprehensive understanding of the phenomenon under investigation. Selecting individuals with the ability to articulate and reflect ensures that the data collected will be meaningful and contribute significantly to the research findings. It is essential for qualitative researchers to prioritize such participants who can best meet the objectives of the study by offering detailed and insightful perspectives.
