CARN Study Guide for
2025
Question 1: What is the primary purpose of an advanced practice nurse (APN) in a
patient care setting?
a) To supervise other nurses
b) To provide direct patient care and advanced clinical practice
c) To manage hospital operations
d) To teach medical students
Answer: b) To provide direct patient care and advanced clinical practice
,Rationale: An APN, including nurse practitioners (NPs), clinical nurse specialists
(CNSs), and nurse anesthetists (CRNAs), is primarily responsible for providing
advanced clinical care, diagnosing, and treating patients, and sometimes supervising
nursing staff or other healthcare providers. Supervising nurses is not their core
responsibility, nor are they involved in hospital management or teaching medical
students in most cases.
Question 2: Which of the following is a critical element in the development of an
evidence-based practice (EBP) model?
a) Clinical expertise only
b) Integration of best research evidence with clinical expertise and patient values
c) Patient preferences as the sole focus
d) Availability of hospital funding
Answer: b) Integration of best research evidence with clinical expertise and patient
values
Rationale: Evidence-based practice involves the integration of the best research
evidence, clinical expertise, and patient preferences. This holistic approach ensures
that care is not only effective based on the latest research but also tailored to
individual patient needs and values. Clinical expertise and patient preferences alone
do not fully define EBP.
Question 3: Which of the following is a key characteristic of transformational
leadership in nursing?
a) Emphasizing adherence to established protocols
b) Prioritizing cost-efficiency above all else
c) Encouraging innovation and professional growth
d) Maintaining a strict hierarchical structure
,Answer: c) Encouraging innovation and professional growth
Rationale: Transformational leadership in nursing focuses on inspiring and
motivating others to achieve high levels of performance, fostering innovation,
professional development, and empowering nurses to grow in their practice. It
emphasizes collaboration and vision rather than strictly following protocols or
focusing only on cost-efficiency.
Question 4: A nurse is providing care to a patient with end-stage renal disease who is
on dialysis. Which of the following is an appropriate goal for this patient’s care?
a) Ensure the patient is able to resume normal kidney function
b) Promote comfort and quality of life
c) Encourage the patient to stop dialysis therapy
d) Prescribe medications that will cure the condition
Answer: b) Promote comfort and quality of life
Rationale: In patients with end-stage renal disease, particularly those on dialysis, the
primary focus is often on improving the quality of life and managing symptoms.
While some patients may experience improved function with treatment, the disease
is generally not curable at this stage, and comfort should be prioritized over
aggressive treatment aimed at reversing the condition.
Question 5: What is the first step in conducting a comprehensive health assessment?
a) Establishing a diagnosis
b) Gathering a detailed health history
c) Performing diagnostic tests
d) Determining the patient’s financial situation
Answer: b) Gathering a detailed health history
, Rationale: The first step in a comprehensive health assessment is to gather a detailed
health history, which provides essential information about the patient’s medical,
family, social, and lifestyle factors. This forms the basis for the subsequent physical
examination and diagnostic tests, which are conducted later in the process.
Question 6: Which legal principle is most relevant to the nurse's role in maintaining
patient confidentiality?
a) Battery
b) Negligence
c) Informed consent
d) HIPAA (Health Insurance Portability and Accountability Act)
Answer: d) HIPAA (Health Insurance Portability and Accountability Act)
Rationale: HIPAA is the federal law that protects patient confidentiality and the
privacy of health information. It requires healthcare providers, including nurses, to
maintain confidentiality and safeguard patient records. Battery, negligence, and
informed consent are important legal principles but are not directly related to the
confidentiality of patient information.
Question 7: What is the best approach for a nurse to take when dealing with a family
who is experiencing conflict over a patient's care plan?
a) Avoid involvement in family matters
b) Encourage the family to resolve the conflict independently
c) Facilitate open communication between family members and healthcare providers
d) Respect the wishes of the most vocal family member
Answer: c) Facilitate open communication between family members and healthcare
providers
