Nursing Process Practice Questions

Correct Answer: C

Rationale: Rationale: 1. Abdominal injection sites have a higher blood supply, leading to faster absorption. 2. Insulin absorption is faster in areas with more blood vessels. 3. Rapid absorption at the abdomen results in quicker onset of action. 4. Other sites may have slower absorption due to less blood flow. Summary: A: Incorrect. Absorption is faster at abdominal sites due to increased blood flow. B: Incorrect. Absorption varies based on injection site blood supply. C: Correct. Abdominal injection sites have rapid insulin absorption. D: Incorrect. Insulin absorption is consistent based on blood flow at injection sites.

Correct Answer: B

Rationale: The correct answer is B: Focus on the patient's presenting situation. This is the first step in the problem-oriented approach as it helps the nurse understand the immediate issues and prioritize data collection. By focusing on the presenting situation, the nurse can gather relevant information efficiently. A: Completing questions in chronological order may not address the current problem effectively. C: Making accurate interpretations of the data comes after data collection, not as the first step. D: Conducting an observational overview is important but typically follows focusing on the presenting situation to guide what observations are necessary.

Correct Answer: A

Rationale: The correct answer is A: circulating nurse. The circulating nurse is responsible for maintaining cleanliness, ensuring proper temperature, humidity, and lighting in the operating room. They coordinate activities, manage supplies, and ensure a safe environment for the surgical team. The scrub nurse assists the surgeon with instruments and supplies, not environmental conditions. The surgeon's main focus is on performing the surgery, not environmental management. The anesthesiologist is responsible for administering anesthesia and monitoring the patient's vital signs, not the operating room environment.

Correct Answer: B

Rationale: The correct answer is B: Re-exposure to a specific antigen. Memory cells are formed after initial exposure to an antigen. Upon re-exposure to the same antigen, memory cells quickly recognize and respond, converting into plasma cells to produce antibodies. This process is known as secondary immune response. Incorrect choices: A: An organ transplant - Organ transplant does not involve the conversion of memory cells to plasma cells. C: Release of lymphokines - Lymphokines are signaling molecules secreted by immune cells but do not directly cause memory cells to convert to plasma cells. D: Initial exposure to an antigen - Initial exposure to an antigen leads to the formation of memory cells, not their conversion to plasma cells upon re-exposure.

Correct Answer: C

Rationale: Rationale: Choice C is correct because antibodies are indeed produced by B-cells as part of the adaptive immune response. B-cells differentiate into plasma cells that produce antibodies to target specific antigens. This process is essential for generating immunity against pathogens. Incorrect Choices: A: Antibody-mediated defense occurs through the B-cell system, not the T-cell system. T-cells are involved in cell-mediated immunity. B: Cellular immunity is mediated by T-cells, not antibodies produced by B-cells. T-cells directly attack infected cells. D: Lymphocytes can increase during an allergic response, but this does not specifically relate to immunity through antibody production by B-cells.
