Question 1 of 5
The nurse is assessing a client with possible Cushing's syndrome. In a client with Cushing's syndrome, the nurse would expect to find:
Correct Answer: C
Rationale: Cushing's syndrome is a disorder characterized by excessive levels of cortisol in the body. One of the classic physical manifestations of Cushing's syndrome is the accumulation of adipose (fat) tissue in specific areas, such as the trunk (central obesity) and dorsocervical area (referred to as a "buffalo hump"). This redistribution of body fat is a key feature in Cushing's syndrome. The thick, coarse skin is commonly seen in conditions like acromegaly, not in Cushing's syndrome. Weight gain in the arms and legs is not a typical finding in Cushing's syndrome. Additionally, hypertension, rather than hypotension, is more commonly associated with excess cortisol levels in Cushing's syndrome.
Question 2 of 5
In fetal period, all are true EXCEPT
Correct Answer: D
Rationale: Face recognition typically occurs earlier than 26 weeks.
Question 3 of 5
A client is diagnosed with human immunodeficiency virus (HIV). After recovering from the initial shock of the diagnosis, the client expresses a desire to learn as much as possible about HIV and acquired immunodeficiency syndrome (AIDS). When teaching the client about the immune system, the nurse states that adaptive immunity is provide by which type of white blood cell?
Correct Answer: D
Rationale: Lymphocytes are the type of white blood cells that provide adaptive immunity. There are two main types of lymphocytes: B cells and T cells. B cells produce antibodies that can specifically recognize and target certain pathogens (including HIV), while T cells have various functions in the immune response, such as directly killing infected cells or helping other immune cells. Adaptive immunity is characterized by the body's ability to remember specific pathogens and mount a targeted response upon subsequent exposures. In the context of HIV and AIDS, understanding the role of lymphocytes in adaptive immunity is essential for the client to comprehend how the virus affects the immune system and why immune function becomes compromised over time.
Question 4 of 5
Which is most descriptive of clinical reasoning?
Correct Answer: B
Rationale: Clinical reasoning is a complex cognitive process used by healthcare providers to make sound clinical decisions about patient care. It involves the gathering and analyzing of information, as well as the formulation and evaluation of potential treatment options. Clinical reasoning is purposeful in that it is driven by the goal of providing the best possible care for the patient. Healthcare providers use their knowledge, skills, and experience to systematically work through patient problems, identify possible solutions, and make informed decisions. The process is goal-directed, aiming to achieve positive health outcomes for the patient based on the best available evidence and clinical expertise.
Question 5 of 5
Which of the ff causes memory cells to convert to plasma cells?
Correct Answer: B
Rationale: Memory cells are a type of immune cell that "remembers" a specific antigen through previous exposure. When the body encounters the same antigen again during a re-exposure, the memory cells quickly recognize it and can rapidly convert into effector cells, such as plasma cells. Plasma cells are specialized cells that produce antibodies targeted against that specific antigen. This rapid conversion process allows the immune system to mount a quicker and more effective response upon encountering the antigen for the second time.
