1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the nurse set the client's intravenous infusion pump?
- A. 13 ml/hour.
- B. 63 ml/hour.
- C. 80 ml/hour.
- D. 125 ml/hour.
Correct answer: B
Rationale: The correct calculation involves dividing the total volume by the total time. In this case, 250 ml/4 hours = 63 ml/hour. The dose of KCl is not used in the calculation as the focus is on the rate of infusion over the specified time period. Choice A (13 ml/hour) is incorrect as it does not result from the correct calculation. Choice C (80 ml/hour) and Choice D (125 ml/hour) are also incorrect calculations and do not match the correct rate of infusion required.
2. What is the most important instruction for the nurse to provide to a 65-year-old client who attends an adult daycare program, is wheelchair-mobile, and has redness in the sacral area?
- A. Take a vitamin supplement tablet once a day.
- B. Change positions in the chair at least every hour.
- C. Increase daily intake of water or other oral fluids.
- D. Purchase a newer model wheelchair.
Correct answer: B
Rationale: For a client with redness in the sacral area, the most critical instruction is to change positions in the chair at least every hour. This is crucial to prevent pressure ulcers, which can develop due to prolonged pressure on the skin and underlying tissues. Regular position changes help relieve pressure on vulnerable areas, promoting circulation and reducing the risk of skin breakdown and pressure ulcer formation.
3. The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin). Which dietary instruction should the nurse include?
- A. Avoid foods high in vitamin K
- B. Increase intake of leafy green vegetables
- C. Consume a consistent amount of foods high in potassium
- D. Limit intake of high-protein foods
Correct answer: A
Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.
4. The healthcare provider plans to administer diazepam, 4 mg IV push, to a client with severe anxiety. How many milliliters should the healthcare provider administer? (Round to the nearest tenth.)
- A. 0.2 mL
- B. 0.8 mL
- C. 1.25 mL
- D. 2.0 mL
Correct answer: B
Rationale: To calculate the volume to administer, use the formula (1 mL × 4 mg) / 5 mg = 0.8 mL. The healthcare provider should administer 0.8 mL of diazepam for a dosage of 4 mg IV push. Choice A is incorrect because it results from an incorrect calculation. Choices C and D are incorrect as they do not align with the correct calculation based on the provided dosage.
5. Before administering a client's medication, the nurse assesses a change in the client's condition and decides to withhold the medication until consulting with the healthcare provider. After consultation with the healthcare provider, the dose of the medication is changed, and the nurse administers the newly prescribed dose an hour later than the originally scheduled time. What action should the nurse take in response to this situation?
- A. Notify the charge nurse that a medication error occurred.
- B. Submit a medication variance report to the supervisor.
- C. Document the events that occurred in the nurse's notes.
- D. Discard the original medication administration record.
Correct answer: C
Rationale: In this scenario, the nurse acted appropriately by withholding the medication, consulting with the healthcare provider, and administering the newly prescribed dose, albeit with a delay. The correct course of action for the nurse is to document all these events in the nurse's notes. Documenting the sequence of actions taken is crucial for maintaining an accurate record of the client's care, ensuring transparency, and providing essential information for future reference and continuity of care. Notifying the charge nurse or submitting a medication variance report may not be necessary as the situation was managed appropriately, and discarding the original medication administration record is not recommended as it is part of the client's medical record and should be kept for documentation purposes.
