Which statement is true regarding the impact of culture on end-of-life decision making?
- A. African-Americans prefer more conservative, less invaasbiirvbe.c ocma/rtees to ptions during the end of life.
- B. Caucasians prefer aggressive and more invasive care options during the end of life.
- C. Culture and religious beliefs may affect end-of-life decision making.
- D. Perspectives regarding end-of-life care are similar betwabeirebn.c oamn/dte swt ithin religious groups.
Correct Answer: C
Rationale: Rationale:
1. Culture and religious beliefs can significantly impact end-of-life decision making by influencing values, beliefs, and preferences.
2. These factors may affect choices related to treatment options, quality of life, and spiritual aspects.
3. Different cultural backgrounds may lead to varying perspectives on autonomy, family involvement, and medical interventions.
4. Option A and B make generalizations based on race, which is not accurate as preferences can vary widely within any racial group.
5. Option D is incorrect as perspectives on end-of-life care can vary even within the same religious group due to individual beliefs and interpretations.

A normal glomerular filtration rate is
- A. less than 80 mL/min.
- B. 80 to 125 mL/min.
- C. 125 to 180 mL/min.
- D. more than 189 mL/min.
Correct Answer: B
Rationale: The correct answer is B (80 to 125 mL/min) because this range reflects the normal glomerular filtration rate (GFR) in adults. GFR measures the rate at which blood is filtered by the kidneys, typically around 125 mL/min. A GFR below 60 mL/min indicates kidney dysfunction, making option A incorrect. Option C (125 to 180 mL/min) is above the normal range. Option D (more than 189 mL/min) is too high and could indicate hyperfiltration, common in conditions like diabetes. Therefore, choice B is the most appropriate within the normal GFR range.
What is true regarding pain and anxiety in the healthy individual? (Select all that apply.)
- A. They activate the sympathetic nervous system.
- B. They decrease stress levels.
- C. They help remove one from harm.
- D. They increase performance levels.
Correct Answer: A
Rationale: The correct answer is A because pain and anxiety trigger the sympathetic nervous system's fight-or-flight response, increasing heart rate, blood pressure, and stress hormones to prepare the body for potential danger. This physiological response helps the individual respond to perceived threats. Choices B, C, and D are incorrect because pain and anxiety typically increase stress levels, do not necessarily remove one from harm, and can hinder rather than enhance performance due to distraction and decreased focus.
The removal of plasma water and some low–molecular weight particles by using a pressure or osmotic gradient is known as
- A. dialysis.
- B. diffusion.
- C. clearance.
- D. ultrafiltration.
Correct Answer: D
Rationale: Ultrafiltration is the correct answer because it involves the removal of plasma water and low-molecular weight particles by using a pressure or osmotic gradient. During ultrafiltration, the pressure gradient pushes the fluid through a semipermeable membrane, separating the substances based on their molecular size. This process allows for the selective removal of unwanted substances while retaining essential components. Dialysis (choice A) involves the removal of waste products from the blood, but it does not specifically target plasma water and low-molecular weight particles. Diffusion (choice B) is the passive movement of particles from an area of higher concentration to an area of lower concentration and is not specific to the removal of plasma water. Clearance (choice C) refers to the rate at which a substance is removed from the blood and does not involve the mechanism of pressure or osmotic gradient utilized in ultrafiltration.
A nurse who plans care based on the patient’s gender, ethn ai bc iri bt .y co, ms /p tei sr ti tuality, and lifestyle is said to demonstrate what focus?
- A. Becoming a moral advocate.
- B. Facilitating all forms of learning.
- C. Responding to diversity.
- D. Using effective clinical judgment.
Correct Answer: C
Rationale: The correct answer is C: Responding to diversity. By considering the patient's gender, ethnicity, spirituality, and lifestyle, the nurse is focusing on responding to diversity in patient care. This approach acknowledges and respects the unique characteristics and backgrounds of individual patients, leading to more culturally competent and effective care.
Choice A: Becoming a moral advocate does not directly relate to considering diversity in patient care. It involves standing up for ethical principles and values in healthcare.
Choice B: Facilitating all forms of learning is not specific to addressing diversity in patient care. It pertains to promoting education and understanding in various learning styles.
Choice D: Using effective clinical judgment is important in nursing practice but does not specifically address the focus on diversity in patient care. It pertains to making sound decisions based on clinical knowledge and expertise.
The nurse is caring for a patient who has a temporary percutaneous dialysis catheter in place. In caring for this patient, the nurse should
- A. apply a sterile gauze dressing to maintain sterility.
- B. replace the transparent dressing every 10 days to prevent manipulation.
- C. assess the catheter site for redness and/or swelling.
- D. use the catheter for drawing blood samples to reduce patient discomfort.
Correct Answer: C
Rationale: The correct answer is C because assessing the catheter site for redness and/or swelling is crucial for early detection of infection. Redness and swelling are common signs of infection at the catheter site, which requires prompt intervention. Applying a sterile gauze dressing (choice A) is not necessary for a temporary percutaneous dialysis catheter. Replacing the transparent dressing every 10 days (choice B) is not recommended as it can increase the risk of infection. Using the catheter for drawing blood samples (choice D) is not appropriate as it can introduce contaminants and increase the risk of infection. Regular assessment of the catheter site is essential for early detection and prevention of complications.
