1. To use the nursing process correctly, what must the nurse do first?
- A. Obtain information about the client
- B. Develop a care plan
- C. Implement interventions
- D. Evaluate the client's outcomes
Correct answer: A
Rationale: The first step in the nursing process is to obtain information about the client. This step involves gathering data through assessment to understand the client's needs, health status, and preferences. Developing a care plan (Choice B) comes after the assessment phase. Implementing interventions (Choice C) and evaluating client outcomes (Choice D) occur in subsequent stages of the nursing process. Therefore, the correct initial step is to gather information about the client to form a foundation for providing individualized care.
2. The PN and UAP enter a client's room and find the client lying on the bed. The PN determines that the client is unresponsive. Which instruction should the PN give the UAP first?
- A. Obtain emergency help
- B. Feel for a carotid pulse
- C. Bring a glucometer to the room
- D. Check the blood pressure
Correct answer: A
Rationale: The correct answer is to instruct the UAP to obtain emergency help first. When a client is unresponsive, it could indicate a life-threatening condition that requires immediate intervention. Ensuring emergency help is on the way is the priority to address the potentially critical situation. Feeling for a carotid pulse, bringing a glucometer, or checking the blood pressure are important assessments but should come after taking steps to secure immediate assistance.
3. The nurse is counseling a young couple who in 2 months are having their third baby. The nurse uses Von Bertalanffy's general system theory applied to families to analyze the family structure. Which best describes the main emphasis of this theory and its application to family dynamics?
- A. It emphasizes the family as a system with interdependent, interacting parts that endure over time to ensure the survival, continuity, and growth of its components.
- B. It emphasizes the social system of the family, such as the organization or structure of the family and how the structure relates to its function.
- C. It emphasizes the developmental stages that all families go through, beginning with marriage; the longitudinal career of the family is also known as the family life cycle.
- D. It addresses how families respond to stress and how the family copes with stress as a group and how each individual member copes.
Correct answer: A
Rationale: Von Bertalanffy's general system theory applied to families emphasizes the family as a system with interdependent, interacting parts that endure over time to ensure the survival, continuity, and growth of its components. This theory focuses on viewing the family as a dynamic system where each member's actions and behaviors impact the whole family unit. Choice B is incorrect as it focuses solely on the social system of the family, while Von Bertalanffy's theory looks at the family as a whole system. Choice C is incorrect as it discusses family developmental stages, which is not the main emphasis of Von Bertalanffy's theory. Choice D is also incorrect as it only addresses how families respond to stress, which is a narrower focus compared to the broader system view of Von Bertalanffy's theory.
4. After meiosis, each new cell nucleus contains _____ chromosomes.
- A. 46
- B. 35
- C. 23
- D. 12
Correct answer: C
Rationale: After meiosis, each resulting cell contains 23 chromosomes. Meiosis is a process that involves two sequential divisions resulting in four daughter cells, each with half the number of chromosomes as the parent cell. In humans, the parent cell has 46 chromosomes (diploid), and after meiosis, the resulting cells (sperm or ova) have 23 chromosomes (haploid). Choice A (46 chromosomes) is incorrect because this is the number of chromosomes in a human diploid cell before meiosis. Choices B (35 chromosomes) and D (12 chromosomes) are incorrect as they do not represent the correct number of chromosomes after meiosis in human cells.
5. A client is scheduled for an intravenous pyelogram. Which of the following actions is appropriate for the nurse to include?
- A. Monitor the client for pain in the suprapubic region.
- B. Ensure the client is free of metal objects.
- C. Administer 240 mL (8 oz) of oral contrast before the procedure.
- D. Assist the client with a bowel cleansing.
Correct answer: B
Rationale: The correct action for the nurse to include before an intravenous pyelogram is ensuring the client is free of metal objects. Metal objects can interfere with the imaging procedure and may need to be removed to prevent artifacts. Monitoring for pain in the suprapubic region (choice A) is not directly related to the procedure and is not a standard pre-procedure action. Administering oral contrast (choice C) is more common for other imaging studies like a CT scan, not an intravenous pyelogram. Assisting with a bowel cleansing (choice D) is not typically required before an intravenous pyelogram.
