1. A healthcare provider is preparing to administer Belimumab to a client with Systemic Lupus Erythematosus. Which of the following actions should the healthcare provider plan to take?
- A. Warm the medication to room temperature before administering.
- B. Administer the medication by IV bolus over 5 minutes.
- C. Dilute the medication in a 5% dextrose and water solution.
- D. Monitor the client for hypersensitivity reactions.
Correct answer: D
Rationale: Correct Answer: Monitoring the client for hypersensitivity reactions is crucial when administering Belimumab due to its known potential for severe infusion reactions and anaphylaxis. The healthcare provider should closely observe the client during the administration to promptly identify and manage any hypersensitivity reactions that may occur. Choice A is incorrect because warming Belimumab is not necessary before administration. Choice B is incorrect as Belimumab should not be administered as an IV bolus over 5 minutes; it should be given as an IV infusion over a longer duration. Choice C is incorrect as Belimumab should not be diluted in a 5% dextrose and water solution.
2. A nurse is providing teaching to a group of older adults about sources of complete and incomplete protein. Which of the following foods should the nurse include as a complete protein?
- A. Yogurt
- B. Fresh vegetables
- C. Nuts
- D. Dried Beans
Correct answer: A: Yogurt
Rationale: Yogurt is the correct answer as it is a complete protein source, containing all nine essential amino acids. Fresh vegetables, nuts, and dried beans are incomplete protein sources as they lack one or more essential amino acids required by the body.
3. The nurse is caring for a client on warfarin with an INR of 1.8. What is the most appropriate action?
- A. Increase the dose of warfarin.
- B. Administer vitamin K.
- C. Hold the warfarin and notify the healthcare provider.
- D. Monitor the client’s INR closely.
Correct answer: D
Rationale: An INR of 1.8 is below the therapeutic range for a client on warfarin, indicating the need for monitoring closely to ensure that the INR levels reach the desired therapeutic range. Increasing the dose of warfarin (Choice A) without proper monitoring may lead to an increased risk of bleeding. Administering vitamin K (Choice B) is not typically recommended unless the client is experiencing major bleeding or requires rapid reversal of warfarin's effects. Holding the warfarin and notifying the healthcare provider (Choice C) may be necessary in certain situations, but the immediate action in this case should be to monitor the client's INR closely to guide further management.
4. When planning care for a client on mechanical ventilation, which mode of ventilation that increases the effort of the client's respiratory muscles should NOT be included in the plan of care?
- A. Assist-control
- B. Synchronized intermittent mandatory ventilation
- C. Continuous positive airway pressure
- D. Pressure support ventilation
Correct answer: Assist-control
Rationale: Assist-control ventilation mode delivers a preset tidal volume at a set rate; however, it may not be suitable for clients who need to maintain some level of respiratory muscle activity. This mode provides full support for each breath, potentially leading to decreased respiratory muscle strength over time. Therefore, it is important to avoid using assist-control mode for clients who require increased effort of respiratory muscles to prevent muscle atrophy and promote optimal respiratory function.
5. A client had a left hip arthroplasty. Which of the following interventions should the nurse use to prevent dislocation?
- A. Maintain foam wedge between legs
- B. Monitor for shortening of the affected leg
- C. Encourage use of elastic stockings
- D. Avoid flexing the hips more than 60 degrees
Correct answer: A
Rationale: The correct answer is to maintain a foam wedge between the legs. This intervention helps prevent hip dislocation by maintaining proper leg alignment after surgery. Monitoring for shortening of the affected leg (choice B) is not directly related to preventing dislocation. Encouraging the use of elastic stockings (choice C) is more related to preventing deep vein thrombosis rather than dislocation. Avoiding flexing the hips more than 60 degrees (choice D) is important post-surgery, but it is not the most direct intervention to prevent dislocation.
