Adult Health Nursing Quizlet Final

Correct Answer: B

Rationale: Performing a sigmoidoscopy, which is a procedure to examine the lower part of the colon and rectum, during a health screening event at a community center may not be practical for several reasons. Firstly, sigmoidoscopy is relatively invasive compared to other screening methods for colon cancer, such as fecal occult blood tests or colonoscopy. Secondly, it can be expensive to perform, especially in a community setting where cost-effectiveness is an important consideration. Therefore, Nurse Filomena would likely point out the invasiveness and cost factors to explain why a sigmoidoscopy may not be suitable for a health screening event at a local community center.

Correct Answer: A

Rationale: ** In a patient with ARDS, the priority intervention to manage respiratory failure is to initiate lung-protective mechanical ventilation with low tidal volume. ARDS is characterized by widespread inflammation and injury to the alveoli, leading to impaired gas exchange and severe hypoxemia. Lung-protective ventilation strategies aim to minimize ventilator-induced lung injury by using lower tidal volumes (around 6 mL/kg of predicted body weight) to reduce barotrauma and volutrauma.

Correct Answer: C

Rationale: The night nurse is expected to collect the patient charts from various departments every three nights. Among the tasks listed, binding the charts as they are is not typically a responsibility of the night nurse. This task is usually handled by administrative staff or professional medical records technicians who are trained to manage the organization and storage of patient charts. The night nurse's primary focus should be on ensuring the correct order of the charts, checking for completeness, and addressing any issues such as torn pages by taping or repairing them to maintain the integrity of the patient records.

Correct Answer: C

Rationale: Maintaining patient confidentiality is a foundational principle in healthcare ethics. Nurses are obligated to keep all information about patients confidential, which means not disclosing any patient-related information to unauthorized individuals. This includes refraining from discussing patient cases with others who are not directly involved in the care of the patient. Sharing patient information without consent can be a breach of trust and privacy, which can have legal and ethical implications. Therefore, in order to uphold the principle of confidentiality, nurses must keep all matters about the patient as a secret.

Correct Answer: A

Rationale: Plasma cells are the primary type of cells responsible for the production of antibodies during the humoral immune response. When activated by antigens, B cells differentiate into plasma cells, which are specialized in producing large quantities of antibodies. These antibodies are essential in fighting off infections by binding to antigens and marking them for destruction by other immune cells. T helper cells assist in activating B cells, but the actual production of antibodies is mainly carried out by plasma cells. Memory B cells are involved in mounting a rapid and specific secondary response upon re-exposure to the same antigen. Macrophages play a role in phagocytosis and antigen presentation, but they are not the primary cells responsible for producing antibodies during the humoral immune response.
