1. What is responsible for initiating clonal selection?
- A. B cells
- B. T cells
- C. Antigens
- D. Lymphocytes
Correct answer: C
Rationale: Antigens are the correct answer as they are the molecules that trigger the immune response by binding to specific B or T cells. This binding activates these cells, leading to their proliferation and differentiation to fight off the antigen. B cells and T cells are the responders to antigens, not the initiators of clonal selection. Lymphocytes is a broad term encompassing both B and T cells, so it is not the specific factor responsible for initiating clonal selection.
2. What is the best way to manage a patient's intake of dietary fiber?
- A. Increase intake gradually
- B. Increase intake suddenly
- C. Decrease intake abruptly
- D. Maintain a high intake
Correct answer: A
Rationale: The best way to manage a patient's intake of dietary fiber is to increase it gradually. This approach helps prevent gastrointestinal discomfort that may arise from a sudden increase in fiber intake. Choice B is incorrect because increasing intake suddenly can lead to digestive issues. Choice C is incorrect as decreasing fiber intake abruptly may not be necessary and can impact overall health. Choice D is incorrect as maintaining a high intake without considering the patient's current intake level can also cause digestive problems.
3. There are several pitfalls that should be avoided when using social media of any type. For example, a nurse or student could be found guilty of libel in which of the following scenarios?
- A. Snapping a selfie with a patient
- B. Posting a positive review of the hospital where the student completed clinicals
- C. Creating a closed online forum where students can discuss clinical experiences without providing client information
- D. Complaining about her nurse preceptor on social media, discussing the preceptor�s unprofessional characteristics.
Correct answer: D
Rationale: Statements about individuals encountered in one�s professional or educational life that could damage that person�s reputation may be slander or libel and can be prosecuted as quasi-intentional torts.
4. The Denver II is a test used to assess children. What does it evaluate?
- A. Behavior problems
- B. Developmental status
- C. Body mass index
- D. Infection likelihood
Correct answer: B
Rationale: The Denver II Developmental Screening Test is used to assess a child's development in four areas: personal-social, fine motor-adaptive, language, and gross motor skills. It helps identify children who may need further evaluation. Choice A, behavior problems, is incorrect as the Denver II primarily focuses on developmental milestones rather than behavior. Choice C, body mass index, is unrelated to the assessment of child development. Choice D, infection likelihood, is also not evaluated by the Denver II test.
5. The client is admitted to the emergency department complaining of acute epigastric pain and reports vomiting a large amount of bright red blood at home. Which interventions should the nurse implement?
- A. Assess the client’s vital signs
- B. Start an IV with an 18-gauge needle
- C. Begin iced saline lavage
- D. A, B
Correct answer: D
Rationale: The correct interventions for a client presenting with acute epigastric pain and vomiting bright red blood are to assess the client’s vital signs and start an IV with an 18-gauge needle. Assessing vital signs helps in determining the client's current condition and response to treatment, while starting an IV is crucial for administering medications and fluids. Beginning iced saline lavage is not appropriate in this situation as the priority is to stabilize the client and address potential bleeding. Therefore, options A and B are correct choices, making option D the most appropriate answer.
