A patient presents with chest pain that occurs during heavy lifting or physical exertion and is relieved by rest. An electrocardiogram (ECG) may show transient ST-segment depression. Which cardiovascular disorder is most likely responsible for these symptoms?

Correct Answer: A

Rationale: The given patient's symptoms of chest pain that occurs during heavy lifting or physical exertion and is relieved by rest are consistent with stable angina. Stable angina is characterized by predictable chest pain that occurs with exertion and is typically relieved by rest or nitroglycerin. The transient ST-segment depression on ECG is also a common finding in patients with stable angina, which reflects myocardial ischemia during episodes of chest pain triggered by exertion. In contrast, unstable angina is characterized by chest pain at rest or with minimal exertion that is of increasing frequency, severity, or duration. Acute myocardial infarction is associated with persistent ST-segment elevation or new Q-waves on ECG, and Prinzmetal's angina is characterized by chest pain at rest due to coronary artery spasm rather than exertion.

Correct Answer: C

Rationale: The last and necessary part of any activity should involve an evaluation process. By evaluating the activity, the organizers can gather feedback on what worked well and what areas need improvement. This feedback is crucial for enhancing future activities that are similar in nature. It allows for reflections on the effectiveness of the activity, identifies strengths and weaknesses, and helps in making necessary adjustments for better outcomes in the future. Overall, evaluation ensures continuous improvement and development in organizing successful activities.

Correct Answer: B

Rationale: Teaching the patient diaphragmatic breathing exercises for respiratory support would be the most appropriate intervention to address the symptoms of dyspnea and anxiety in this scenario. Diaphragmatic breathing, also known as belly breathing, focuses on engaging the diaphragm for deep, slow breaths, which can help improve lung expansion and ventilation. This technique can help the patient manage their breathing difficulty and reduce anxiety by promoting relaxation and improving oxygen exchange in the lungs. It empowers the patient with a coping strategy they can use independently to alleviate distressing symptoms at any time. Administering oxygen therapy may be beneficial, but the priority is to teach the patient a technique they can use proactively and routinely. Prescribing benzodiazepines should be considered as an adjunct if non-pharmacological interventions are ineffective in managing anxiety. Referring to a pulmonologist may be necessary for comprehensive evaluation and treatment but may not directly address the immediate symptoms of dyspnea and anxiety.

Correct Answer: C

Rationale: Nurse Ace submitting a report to the physician about committing an error in medication demonstrates accountability. Accountability in healthcare refers to the responsibility of individuals to answer for their actions, decisions, and behaviors in the professional setting. By taking ownership of the mistake and informing the physician, Nurse Ace is showing accountability for her actions, ensuring that patient safety remains a priority. Compliance with reporting errors is essential for quality improvement and patient safety in healthcare settings.

Correct Answer: D

Rationale: Quantitative research is the type of research that involves collecting numerical data, which can be easily quantified and analyzed statistically. It is characterized by its structured methodology, objectivity, and the ability to control variables to a considerable extent. In the context of a study on sleep, where data related to sleep patterns, duration, quality, etc., need to be measured and analyzed in a systematic manner, quantitative research would be the most appropriate choice. This type of research allows for a more precise understanding of the relationships and patterns within the data, providing valuable insights into the sleep-related factors being studied.

Correct Answer: C

Rationale: A Likert Scale is typically used to measure the degree of agreement or disagreement with a set of statements or questions. Respondents are asked to indicate their level of agreement or disagreement using a scale that ranges from, for example, "strongly agree" to "strongly disagree". This makes it a suitable tool for assessing the degree of agreement and disagreement among individuals on various topics or statements. While a Likert Scale can potentially measure other constructs such as satisfaction or acceptance, its primary purpose and most common application involve determining the degree of agreement and disagreement.

Correct Answer: D

Rationale: Postpartum hemorrhage is defined as a blood loss of more than 500 ml within the first 24 hours after vaginal delivery or more than 1000 ml following a cesarean delivery. Excessive bleeding can lead to hypovolemic shock and can be life-threatening if not promptly addressed. Therefore, a blood loss of more than 500 ml/24 hours would lead the nurse to suspect a postpartum hemorrhage and prompt further assessment and intervention.

Correct Answer: B

Rationale: Accurate assessment and intervention by the nurse or helping person are critical factors for successful integration of loss during the grieving process. This involves the nurse's ability to assess the patient's grieving process effectively, identify their needs, provide appropriate support, and intervene when necessary. By utilizing proper assessment techniques and offering timely interventions, the nurse helps facilitate the patient's journey through the grieving process, promoting healthy coping mechanisms and ultimately assisting in achieving successful integration of their loss. Trustworthiness and a healthy attitude about grief are important qualities for a nurse, but without accurate assessment and intervention, the grieving process may not progress smoothly.

Correct Answer: A

Rationale: In the case of a woman in active labor with placenta previa, the priority nursing intervention is to prepare for an immediate cesarean section. Placenta previa is a condition in which the placenta covers part or all of the cervix, which can lead to severe bleeding during labor and delivery. The risk of hemorrhage is significant, making a cesarean section the safest option for both the mother and the baby in this situation. It is crucial to act promptly to prevent complications and ensure the well-being of both the mother and the baby. Administering intravenous oxytocin to augment labor or inserting a Foley catheter to monitor urine output would not address the immediate risk of hemorrhage associated with placenta previa. Implementing bed rest and continuous fetal monitoring may be part of the overall care plan but not the priority intervention in this urgent situation.
