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: A

Rationale: In prioritizing nursing diagnoses, the nurse should consider issues that pose the greatest risk to the patient's immediate well-being. A fluid volume deficit can lead to dehydration and potentially life-threatening complications, making it a priority to address. It is crucial to restore fluid balance to maintain normal body functions and prevent further deterioration of the patient's condition. Ensuring adequate hydration is essential for the patient's overall health and recovery. The other options, such as risk for pain, coping, and body image disturbances, while important, are not as urgent as addressing a fluid volume deficit.

Correct Answer: D

Rationale: In the situation described, where the client experienced a prolonged labor and instrumental delivery, there may be physical and emotional factors impacting breastfeeding success. A lactation consultant is a specialized healthcare provider who can assess the client's breastfeeding difficulties, offer individualized support, and provide guidance on techniques to overcome challenges such as latch issues, positioning problems, and milk supply concerns. Referring the client to a lactation consultant will help ensure that she receives expert assistance tailored to her specific needs, thereby increasing the likelihood of successful breastfeeding. This proactive approach focuses on addressing the root causes of breastfeeding difficulties and supporting the client in achieving her breastfeeding goals.

Correct Answer: B

Rationale: The patient who had a left total hip replacement surgery due to osteoarthritis needs to strictly follow the postoperative teaching of being shown how to gently irrigate the external auditory canal because this instruction is unrelated to a hip replacement surgery. The other options are not relevant to the surgery and patient's condition. Option A about airplane travel, Option C about dizziness, and Option D about hair washing are not appropriate instructions for a patient who had a hip replacement. It is important for healthcare providers to give accurate and relevant postoperative instructions to help the patient recover successfully.

Correct Answer: C

Rationale: One of the main consequences of hypoxemia, which is low oxygen levels in the blood, is decreased oxygen saturation. Oxygen saturation refers to the percentage of hemoglobin molecules in the blood that are bound to oxygen. When there is insufficient oxygen in the blood due to hypoxemia, the oxygen saturation levels will drop. This can lead to symptoms such as shortness of breath, confusion, rapid heart rate, and ultimately can result in tissue damage if not corrected promptly. Monitoring oxygen saturation levels is crucial in the immediate post-operative phase to ensure adequate ventilation and oxygenation for the patient's recovery.

Correct Answer: C

Rationale: The clinical presentation described with fever, headache, maculopapular rash starting on the face and spreading to the trunk and extremities, along with leukopenia and thrombocytopenia suggests a likely diagnosis of Rocky Mountain spotted fever (RMSF), which is caused by the bacterium Rickettsia rickettsii.

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: The aim of human sciences, including nursing as a human science, is to make meaningful interpretations of the phenomena being studied. Unlike natural sciences that may focus on prediction, control, or seeking causal explanations, the human sciences aim to understand and interpret human experiences, behaviors, and relationships in a meaningful way. In nursing, this involves not only understanding the biological aspects of health and illness but also considering the holistic and humanistic aspects of care, such as emotions, values, beliefs, and perceptions. By making meaningful interpretations, nurses can better understand their patients and provide individualized and patient-centered care.

Correct Answer: B

Rationale: Consuming alcohol while on benzodiazepine therapy can increase the central nervous system depressant effects of benzodiazepines, leading to excessive sedation, respiratory depression, and even overdose. It is important for patients to avoid alcohol to prevent these potential dangerous interactions and to ensure the safe and effective use of their medication.
