1. What is the primary function of surfactant in the lungs?
- A. Reduce surface tension
- B. Enhance oxygen absorption
- C. Facilitate carbon dioxide release
- D. Increase lung volume
Correct answer: A
Rationale: The primary function of surfactant in the lungs is to reduce surface tension in the alveoli. This reduction in surface tension prevents lung collapse and allows for easier breathing. It is particularly crucial in premature infants to help with lung expansion. Choice B is incorrect because surfactant primarily affects surface tension, not oxygen absorption. Choice C is incorrect because surfactant's main role is not in facilitating carbon dioxide release. Choice D is incorrect because surfactant does not directly increase lung volume; its main role is in reducing surface tension.
2. A client is post-operative day two from a total hip arthroplasty. The nurse notices the surgical wound is red and warm to the touch. What is the most appropriate action?
- A. Apply an ice pack to the incision site.
- B. Monitor the client's temperature.
- C. Document the findings and continue to monitor.
- D. Notify the healthcare provider.
Correct answer: D
Rationale: The correct action when a nurse notices redness and warmth at the surgical wound post total hip arthroplasty is to notify the healthcare provider. These signs may indicate an infection, and prompt evaluation by the healthcare provider is crucial to initiate appropriate treatment. Applying an ice pack (Choice A) may not address the underlying issue of a potential infection. Monitoring the client's temperature (Choice B) is important but not the priority when signs of infection are present. Documenting the findings and continuing to monitor (Choice C) is necessary but should be accompanied by notifying the healthcare provider for further assessment and intervention.
3. The single mother of a child with a head injury is sitting at the child's bedside crying when the PN enters the room. The mother states, 'Why did this happen to my child? I just can't cope with this.' How should the PN respond?
- A. Ask her to share how the injury occurred to her child.
- B. Recommend that she remain calm and positive for her child.
- C. Express that the present situation must be overwhelming.
- D. Determine if someone else can help her cope with this tragedy.
Correct answer: C
Rationale: Expressing empathy and acknowledging the mother's feelings helps in providing emotional support during a difficult time. This response validates her emotions and offers a comforting presence. Choice A is not appropriate as it focuses on gathering information rather than addressing the mother's emotional distress. Choice B may come off as dismissive of the mother's feelings and oversimplifies the complexity of the situation. Choice D shifts the responsibility to someone else instead of offering immediate support and comfort.
4. A nurse is assessing a day-old infant for jaundice. Which of the following is the best method for this?
- A. Applying pressure over a bony area such as the forehead and evaluating the skin color after the pressure is removed
- B. Assessing the color of the infant’s hands and feet
- C. Assessing the infant’s tongue
- D. Assessing the infant’s arms and legs
Correct answer: A
Rationale: The correct answer is A. Applying pressure over a bony area and evaluating the skin color after the pressure is removed is the most accurate method for assessing jaundice in a day-old infant. This technique helps in identifying any yellowing of the skin, which is a key indicator of jaundice. Choices B, C, and D are less effective methods for assessing jaundice in a newborn. Assessing the color of the hands and feet may not give a reliable indication of jaundice, while evaluating the tongue, arms, and legs are not as specific or accurate as applying pressure over a bony area.
5. For an older postoperative client with the nursing diagnosis 'impaired mobility related to fear of falling,' which desired outcome best directs the nurse's actions for the client?
- A. The client will ambulate with assistance every 4 hours
- B. The physical therapist will instruct the client in the use of a walker
- C. The client will use self-affirmation statements to decrease fear
- D. The nurse will place a gait belt on the client prior to ambulation
Correct answer: C
Rationale: Encouraging the client to use self-affirmation statements is the most appropriate desired outcome in this scenario. By utilizing self-affirmation statements, the client can address their fears directly and build confidence, which can ultimately lead to a reduction in fear of falling. While ambulating with assistance (choice A) is important, the focus here is on addressing the fear itself. Instructing the client in the use of a walker (choice B) and placing a gait belt on the client (choice D) are interventions that may be helpful but do not directly address the client's fear of falling.
