What is the most important assessment for the LPN/LVN to perform on a client with a history of chronic obstructive pulmonary disease (COPD) receiving oxygen therapy at 2 liters per minute via nasal cannula?
- A. Assess the client's respiratory rate and effort.
- B. Measure the client's oxygen saturation level.
- C. Monitor the client's arterial blood gas levels.
- D. Check the client's blood pressure.
Correct Answer: B
Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.

Seconal 0.1 gram PRN at bedtime is prescribed to a client for rest. The scored tablets are labeled 1.5 grains per tablet. How many tablets should the LPN/LVN plan to administer?
- A. 0.5 tablet
- B. 1 tablet
- C. 1.5 tablets
- D. 2 tablets
Correct Answer: B
Rationale: To calculate the number of tablets needed, convert the prescribed dose of Seconal from grams to grains. Since 1 gram is equal to approximately 15.43 grains, 0.1 gram is roughly 1.543 grains. Given that each tablet contains 1.5 grains, administering 1 tablet (which is slightly more than the 1.543 grains needed) provides the correct dose of Seconal. Therefore, the LPN/LVN should plan to administer 1 tablet. Choice A (0.5 tablet) is incorrect as it would provide less than the required dose. Choice C (1.5 tablets) and Choice D (2 tablets) are incorrect as they would exceed the necessary dosage.
A healthcare professional is reviewing measures to prevent back injuries with assistive personnel (AP). Which of the following instructions should the healthcare professional include?
- A. When lifting an object, spread your feet apart to provide a wide base of support.
- B. Always lift objects with your back straight and not your legs.
- C. Avoid using any assistive devices.
- D. Bend at the waist to reach objects.
Correct Answer: A
Rationale: The correct instruction to prevent back injuries while lifting is to spread your feet apart to provide a wide base of support. This helps in maintaining stability and reduces the risk of back injury. Choice B is incorrect as lifting objects with your back straight and using your legs is the recommended technique. Choice C is incorrect because assistive devices can actually help prevent back injuries by providing support. Choice D is incorrect as bending at the waist to reach objects can strain the back muscles and increase the risk of injury.
The nurse admits a 7 year-old to the emergency room after a leg injury. The x-rays show a femur fracture near the epiphysis. The parents ask what will be the outcome of this injury. The appropriate response by the nurse should be which of these statements?
- A. The injury is expected to heal quickly because of thin periosteum.
- B. In some instances the result is a retarded bone growth.
- C. Bone growth is stimulated in the affected leg.
- D. This type of injury shows more rapid union than that of younger children.
Correct Answer: B

A nurse is planning strategies to manage time effectively for client care. What should the nurse implement?
- A. Use the planning step of the nursing process to prioritize client care delivery.
- B. Delegate all tasks to assistive personnel.
- C. Focus on completing tasks in the order they are assigned.
- D. Avoid using a checklist for daily tasks.
Correct Answer: A
Rationale: The correct answer is A. Using the planning step of the nursing process to prioritize client care delivery is crucial for effective time management. By prioritizing tasks based on client needs and acuity levels, the nurse can ensure that the most critical care is provided in a timely manner. Choice B is incorrect because while delegation is important, not all tasks can be delegated, and the nurse is ultimately responsible for the care provided. Choice C is incorrect as completing tasks in the order they are assigned may not align with the urgency of client needs. Choice D is incorrect as using a checklist can help the nurse stay organized and ensure that all necessary tasks are completed.
A client requires bed rest and has a prescription for anti-embolic stockings. Which of the following actions should the nurse take?
- A. Apply the stockings with the creases on the front of the leg.
- B. Apply the stockings while the client's legs are in a dependent position.
- C. Remove the stockings at least once per shift.
- D. Remove the stockings while the client is sitting in a reclining chair.
Correct Answer: C
Rationale: The correct action for the nurse to take is to remove the anti-embolic stockings at least once per shift. This is essential to assess the client's circulation and skin integrity. Option A is incorrect because the stockings should be applied without creases to ensure proper compression. Option B is incorrect as the stockings should be applied when the client's legs are elevated, not in a dependent position. Option D is incorrect as removing the stockings while the client is sitting in a reclining chair is not necessary and does not provide the appropriate assessment opportunity.
