1. A client who takes metformin for diabetes mellitus type 2 is nothing by mouth (NPO) for surgery. What pre-op prescription should the practical nurse (PN) anticipate for this client's glucose management?
- A. NPO except for metformin and regular snacks
- B. NPO except for oral antidiabetic agent
- C. Novolin-N insulin subcutaneously twice daily
- D. Regular insulin subcutaneously per sliding scale
Correct answer: D
Rationale: When a client taking metformin for diabetes mellitus type 2 is NPO for surgery, it is crucial to manage their glucose levels effectively. The best approach in this situation is to prescribe regular insulin subcutaneously according to a sliding scale based on the client's blood glucose levels. This method allows for precise adjustment of insulin doses to maintain blood glucose within the target range while the client is unable to take oral medications. Choices A and B are incorrect because metformin is typically held when a client is NPO, and oral antidiabetic agents may not provide sufficient glucose control. Choice C is incorrect as Novolin-N insulin given twice daily may not offer the flexibility needed for glucose management in a surgical setting where the client's intake is restricted.
2. The nurse is triaging clients who have been injured during a tornado. Which client requires immediate action?
- A. A young male with a minor laceration on his forearm.
- B. An elderly woman with a dislocated shoulder who is calm.
- C. A middle-aged female with a broken humerus who is unable to follow commands and is crying.
- D. A teenager with abrasions and a bruised knee.
Correct answer: C
Rationale: The middle-aged female with a broken humerus who is unable to follow commands and is crying requires immediate action. These symptoms indicate a possible head injury or severe emotional distress that need urgent attention. Choice A is not as urgent since a minor laceration can be addressed after more critical cases. Choice B, although having a dislocated shoulder, is stable, as the client is calm. Choice D presents with minor injuries that can wait while more critical cases are addressed.
3. While instructing a male client's wife in the performance of passive range-of-motion exercises to his contracted shoulder, the nurse observes that she is holding his arm above and below the elbow. What nursing action should the LPN/LVN implement?
- A. Acknowledge that she is supporting the arm correctly.
- B. Encourage her to keep the joint covered to maintain warmth.
- C. Reinforce the need to grip directly under the joint for better support.
- D. Instruct her to grip directly over the joint for better motion.
Correct answer: A
Rationale: Acknowledging that the client's wife is supporting the arm correctly is the appropriate nursing action in this scenario. By doing so, the nurse reinforces correct technique and promotes confidence. Choice B is incorrect as the issue is not about maintaining warmth. Choice C is incorrect as gripping directly under the joint is not necessary in this case. Choice D is incorrect as instructing to grip directly over the joint may not provide the best support for passive range-of-motion exercises.
4. A nurse working on a mental health unit receives a community call from a person who is tearful and states, 'I just feel so nervous all of the time. I don't know what to do about my problems. I haven't been able to sleep at night and have hardly eaten for the past 3 or 4 days.' The nurse should initiate a referral based on which assessment?
- A. Altered thought processes.
- B. Moderate levels of anxiety.
- C. Inadequate social support.
- D. Altered health maintenance.
Correct answer: B
Rationale: The nurse should initiate a referral based on moderate levels of anxiety (B) as the client reports feeling nervous all the time, sleep disturbances, poor appetite, and difficulty solving problems. These symptoms are indicative of significant anxiety levels. The client does not mention symptoms related to altered thought processes (A) or inadequate social support (C). There is insufficient information to suggest altered health maintenance (D) as a reason for referral in this scenario.
5. What finding signifies that children have attained the stage of concrete operations according to Piaget?
- A. Demonstrates exploration of the environment through sight and movement
- B. Thinks in mental images or word pictures
- C. Makes the moral judgment that 'stealing is wrong'
- D. Reasons that homework is time-consuming yet necessary
Correct answer: C
Rationale: The correct answer is C, 'Makes the moral judgment that 'stealing is wrong''. This finding signifies the attainment of the concrete operational stage according to Piaget. At this stage, children begin to understand rules and logic, including moral judgments. Choice A is incorrect because it does not specifically relate to concrete operational thinking. Choice B is incorrect as it refers more to the preoperational stage where children engage in symbolic thought. Choice D is also incorrect as it involves practical reasoning, which is not directly related to the concrete operational stage according to Piaget.
