Adult Health Nursing Quizlet Final

Correct Answer: B

Rationale: The extraneous variable in a study is a variable that is not the main focus of the study but could potentially impact the results. In this case, the length of stay is an extraneous variable because it is not directly related to the research question or objective of the study. The study is likely focused on factors such as patient age, complications, or date of admission, making the length of stay an irrelevant variable in this context.

Correct Answer: C

Rationale: When discharging a suicidal patient who has been taking tricyclic antidepressant drugs, it is crucial for the nurse to evaluate the risk for suicide by overdose of the medication. Tricyclic antidepressants have a narrow therapeutic index, meaning that the difference between a therapeutic dose and a toxic dose can be quite small. This makes them particularly dangerous in cases of overdose, as they can lead to severe toxic effects, including cardiac arrhythmias, seizures, and death.

Correct Answer: C

Rationale: In this situation, the most appropriate response for the palliative nurse is to validate the patient's feelings of guilt and offer support to address their concerns. It is important to acknowledge the patient's emotions and help them navigate through their guilt in a compassionate and understanding manner. By validating their feelings, the nurse can create a safe space for the patient to express their concerns and work towards finding solutions to alleviate their guilt. This approach fosters trust and a therapeutic relationship between the patient and the nurse, ultimately promoting emotional well-being and facilitating open communication.

Correct Answer: B

Rationale: Total care nursing is a nursing care delivery model where one nurse is assigned to provide comprehensive care to a patient for an entire shift. In this case, the private duty nurse is providing holistic care to the post-caesarian patient during the shift, which aligns with the principles of total care nursing. This approach allows the nurse to focus on the individual needs of the patient and provide all aspects of care, promoting continuity and personalized attention. Total care nursing ensures that the patient receives consistent and dedicated care from the same nurse, enhancing the patient's overall experience and outcomes.

Correct Answer: C

Rationale: Humoral immunity is primarily responsible for protecting against infections by pathogens like viruses. In the case of the hepatitis B virus (HBV), the individual is exposed to the virus and develops immunity, which is typically mediated by antibodies produced by B cells. These antibodies circulate in the blood and can neutralize the virus, preventing future infections. This type of immunity is known as humoral immunity, as it involves the production of antibodies that target specific antigens, such as those present on the surface of the hepatitis B virus. In contrast, passive immunity is when antibodies are transferred from an external source, innate immunity provides immediate, non-specific defenses against pathogens, and cell-mediated immunity involves the activation of T cells to combat intracellular pathogens.
