Correct Answer: D

Rationale: A nurse should have a sense of accountability for his actions. This means taking responsibility for one's decisions and behaviors while working in the healthcare setting. Accountability ensures that the nurse is aware of the consequences of his actions and is willing to accept ownership and follow through on commitments. It is a critical aspect of nursing practice as it helps maintain professional standards, promote patient safety, and uphold trust and integrity within the profession. Nurses are entrusted with the well-being of their patients, so being accountable for their actions is essential in providing high-quality care and maintaining ethical standards.

Correct Answer: B

Rationale: Family support is a crucial consideration when planning the care of the elderly. The availability of family members to provide emotional support, assistance with daily activities, and decision-making can greatly impact the overall well-being of the elderly individual. Family support can help reduce feelings of isolation, ensure that the elderly person's needs are being met, and provide a sense of security and comfort. Additionally, involving family members in the care planning process can help create a collaborative and comprehensive care approach that considers the preferences and values of the elderly person. Considering the level of family support is essential for creating a care plan that meets the unique needs and circumstances of each elderly individual.

Correct Answer: B

Rationale: Refeeding syndrome is a potentially dangerous condition that can occur in malnourished individuals when nutrition is reintroduced too quickly. It is characterized by shifts in electrolytes, fluid imbalance, and metabolic abnormalities. Monitoring for decreased bowel sounds, nausea, bloating, and abdominal distention is the priority action to prevent complications associated with refeeding syndrome. These symptoms can indicate gastrointestinal issues such as ileus or overfeeding, which can lead to further complications. Early recognition and intervention can help prevent serious consequences of refeeding syndrome.

Correct Answer: B

Rationale: Monitoring oxygen saturation with pulse oximetry is essential for preventing respiratory depression in a patient prescribed an opioid analgesic. Opioid analgesics can suppress the respiratory drive, leading to respiratory depression. By constantly monitoring the patient's oxygen saturation levels with pulse oximetry, nurses can promptly detect any signs of respiratory depression and intervene early to prevent serious complications. This allows for timely adjustments in the medication dosage or administration of other supportive measures to maintain adequate oxygenation and prevent respiratory compromise. Administering naloxone prophylactically may be necessary in case of an opioid overdose but is not typically done as a preventive measure. Encouraging deep breathing exercises can help prevent respiratory complications postoperatively but may not be sufficient in the presence of opioid-induced respiratory depression. Administering bronchodilators as needed is not directly related to preventing respiratory depression caused by opioid analgesics.

Correct Answer: B

Rationale: Autonomy is the ethical principle that respects an individual's right to make their own decisions about their medical treatment, even if it goes against medical advice or the preferences of others. In this case, the 70-year-old patient has voluntarily decided not to have the pacemaker inserted despite the physician's recommendation. The fact that the patient's decision is respected by the family reflects the importance of honoring the patient's autonomy and right to make decisions about their own healthcare.
