Which of the following is the central theme of Sr. Calista Roys theory

Correct Answer: C

Rationale: The central theme of Sr. Callista Roy's theory is adaptation. Roy's Adaptation Model focuses on the individual's ability to adapt to internal and external stimuli in order to maintain health and well-being. The theory emphasizes the interconnectedness of the individual and their environment, highlighting the dynamic process of adaptation in response to stimuli. By focusing on adaptation, Roy's theory guides nursing practice in promoting holistic care that supports individuals in adapting to changes and achieving optimal health outcomes.

Correct Answer: C

Rationale: Medico-legal charts are typically stored for a minimum of 10 years after the case is closed to ensure compliance with legal requirements and to provide a comprehensive record of the medical care provided. This duration allows for potential future reference, follow-up treatment, or legal purposes that may arise within the specified timeframe. It is important to maintain these records for an extended period to protect both the patient's rights and the healthcare provider's accountability. Additionally, storing medico-legal charts for 10 years aligns with standard retention practices in the healthcare industry.

Correct Answer: A

Rationale: Immunological memory is primarily maintained by the clonal expansion of memory B cells. Memory B cells are a type of long-lived immune cell that originates from previously activated B cells during an immune response to a pathogen. When the immune system encounters the same pathogen again, memory B cells can quickly recognize and respond to it by undergoing rapid clonal expansion and differentiation into plasma cells that produce specific antibodies. This quick and robust response leads to the more efficient elimination of the pathogen during secondary exposure, resulting in the faster and stronger immune response characteristic of immunological memory.

Correct Answer: B

Rationale: The right to refuse treatment is a fundamental patient right. In this case, the physician ordering medications for the client to take at home without the client's input or agreement could possibly violate the client's right to refuse treatment. It is important for patients to have the autonomy to make decisions regarding their own treatment, especially when they are still weak and symptomatic. Patients should have the opportunity to discuss their treatment plan with their healthcare provider and express any concerns or preferences they may have.

Correct Answer: A

Rationale: Wearing a mask is an essential infection control measure to prevent the spread of respiratory illnesses, including COVID-19. By wearing a mask, Nurse Emma can reduce the risk of inhaling or exhaling respiratory droplets that may contain infectious particles, thus helping to protect herself and the family members she is visiting. Masks are particularly crucial when interacting with individuals who are sick or when physical distancing may be challenging. While using gloves, face shields, and gowns are also important infection control measures in certain situations, wearing a mask is the most relevant and effective measure during a home visit to prevent respiratory transmission of infections.

Correct Answer: D

Rationale: Taking off the room lights and drawing the window shades would provide a calm and soothing environment for the five-year-old patient admitted due to pneumonia with symptoms of cough, respiratory distress, anxiety, and dehydration. By creating a dim and quiet atmosphere, it can help reduce the child's anxiety levels, promote rest and relaxation, and potentially aid in the management of distress caused by pneumonia. Providing a quiet and dark environment can also support the child's comfort and recovery process during the hospital stay.

Correct Answer: D

Rationale: Record keeping involves several key steps such as structuring, securing, and storing information. However, easy disposal is not a step in record keeping. In fact, it is important to carefully consider the disposal of records in a secure and responsible manner to protect sensitive information and comply with relevant regulations. Proper disposal methods should be followed to ensure that records are not accessible to unauthorized individuals and that any sensitive information is properly destroyed to prevent misuse or breaches of privacy. Therefore, easy disposal is not a recommended practice in effective record keeping.

Correct Answer: C

Rationale: In response to chronic hypoxia, the body adapts to increase oxygen delivery to tissues by increasing cardiac output. This is achieved by increasing the heart rate and stroke volume, allowing more oxygenated blood to be pumped to the tissues. The increased cardiac output helps compensate for the lower oxygen levels in the blood, ensuring that tissues receive an adequate supply of oxygen despite the hypoxic conditions. This physiological adaptation is essential for maintaining tissue oxygenation and supporting overall cellular function in the presence of chronic hypoxia.

Correct Answer: B

Rationale: When a patient receiving palliative care for end-stage COPD expresses a desire to discuss advance care planning, the palliative nurse should initiate a conversation about advance directives and future care preferences. Advance care planning involves discussing and documenting a patient's preferences regarding future medical care, particularly in situations where the patient may no longer be able to make decisions. This discussion helps ensure that the patient's wishes are respected and followed in the event they are unable to communicate their preferences. By engaging in advance care planning discussions, the nurse can help the patient feel empowered, supported, and in control of their medical care decisions. It also allows healthcare providers to align care with the patient's values and goals, ultimately improving quality of life and ensuring dignity at the end of life.
