The nurse knows which of the following is true about immunity?

Correct Answer: C

Rationale: Antibodies, also known as immunoglobulins, are proteins produced by a type of white blood cell called B-lymphocytes (B-cells). These antibodies play a crucial role in the immune response by recognizing and binding to specific antigens such as pathogens. This binding can lead to the inactivation of the pathogens or marking them for destruction by other immune cells. B-cells are a key component of the humoral immune response, which involves the production of antibodies to defend against infections. The statement that antibodies are produced by the B-cells is, therefore, true.

Correct Answer: B

Rationale: Option B, "I told her she is wrong and I explained to her what is right," would require the nurse to give further teaching because it indicates a lack of understanding about how to communicate with a person experiencing hallucinations. People with hallucinations may have a distorted sense of reality, and arguing with them or insisting on what is "right" can be counterproductive. The daughter would benefit from additional education on how to effectively communicate and support her father during episodes of hallucinations.

Correct Answer: C

Rationale: Tuberculosis is primarily spread through the air when an infected person coughs, sneezes, speaks, or sings, releasing bacteria-containing droplets into the air. Therefore, it is important for the individual with TB to cover their mouth and nose when coughing or sneezing to prevent the spread of the bacteria. By coughing into a disposable tissue or a handkerchief that can be washed in hot water, the risk of spreading the infection to others is significantly reduced. This measure helps minimize the transmission of the disease within the household and community.

Correct Answer: A

Rationale: Placing a client in a modified Trendelenburg position involves having the client lie flat on the back with the legs elevated above the level of the heart. The main purpose of this position is to help increase blood pressure in cases of hypotension or shock. By raising the legs above the heart level, gravity helps to facilitate the return of venous blood to the heart, which can increase cardiac output and, consequently, blood pressure. This position is commonly used in clinical settings to help improve perfusion to vital organs and assist in stabilizing a client's blood pressure.
