1. A child is postoperative following a tonsillectomy. Which of the following actions should the nurse take?
- A. Administer analgesics to the child on a routine schedule throughout the day and night.
- B. Offer fluids to the child immediately after surgery.
- C. Allow the child to return to solid foods gradually.
- D. Avoid administering any medication until the child is fully awake.
Correct answer: A
Rationale: Administering analgesics to the child on a routine schedule throughout the day and night is crucial for managing postoperative pain effectively and ensuring the child's comfort. Pain management is a priority in the postoperative period to promote healing and prevent complications. Offering fluids to the child immediately after surgery (Choice B) is essential to prevent dehydration, but pain control takes precedence. Allowing the child to return to solid foods gradually (Choice C) is important, but initially, the child may need to start with clear liquids and progress to soft foods post-tonsillectomy. Avoiding administering any medication until the child is fully awake (Choice D) is not advisable because timely pain relief is essential for the child's comfort and recovery.
2. The healthcare professional is preparing to administer a medication through a nasogastric (NG) tube. Which action should the healthcare professional take to ensure proper administration?
- A. Flush the tube with 30 ml of water before and after medication administration.
- B. Administer the medication with food to prevent nausea.
- C. Verify tube placement by aspirating stomach contents.
- D. Dilute the medication with normal saline before administration.
Correct answer: A
Rationale: Flushing the NG tube with water before and after medication administration is essential to ensure the tube is patent and prevent clogging. This action helps in clearing the tube and ensures that the medication is delivered properly. Administering medication with food (Choice B) may not be appropriate for all medications and can interfere with their absorption. Verifying tube placement by aspirating stomach contents (Choice C) is important but does not directly relate to ensuring proper medication administration. Diluting the medication with normal saline (Choice D) is not a standard practice for administering medications through an NG tube.
3. A nurse is providing teaching to an older adult client who has constipation. Which of the following statements should the nurse include in the teaching?
- A. Sit on the toilet 30 minutes after eating a meal.
- B. Increase your fluid intake to help with bowel movements.
- C. Exercise regularly to improve bowel function.
- D. Consume more high-fiber foods to prevent constipation.
Correct answer: A
Rationale: The correct statement the nurse should include in the teaching is to 'Sit on the toilet 30 minutes after eating a meal.' This advice can help establish a regular bowel routine and improve bowel movement. Option B, 'Increase your fluid intake to help with bowel movements,' while important, is not specific to the time after eating and does not directly address the need for establishing a routine. Option C, 'Exercise regularly to improve bowel function,' is also important but does not address the timing of bowel movements. Option D, 'Consume more high-fiber foods to prevent constipation,' is beneficial for preventing constipation but does not address the timing aspect related to bowel movements.
4. At 0100 on a male client's second postoperative night, the client states he is unable to sleep and plans to read until feeling sleepy. What action should the nurse implement?
- A. Stay with the client and offer assistance with relaxation techniques
- B. Assess the client's pain level and administer pain medication if needed
- C. Bring the client a prescribed PRN sedative-hypnotic
- D. Encourage the client to engage in a quiet, non-stimulating activity until feeling sleepy
Correct answer: C
Rationale: At 0100 on the client's second postoperative night, the nurse should address the client's inability to sleep. Providing a prescribed PRN sedative-hypnotic is appropriate in this situation to help the client rest. Choice A is incorrect because leaving the room and closing the door does not directly address the client's sleep concern. Choice B is not the priority at this moment since the client's main issue is insomnia, not pain. Choice D, while encouraging a non-stimulating activity, does not provide immediate relief for the client's sleeplessness as a sedative-hypnotic would.
5. A nurse is preparing to check a client's blood pressure. Which of the following actions should the nurse take?
- A. Apply the cuff above the client's antecubital fossa.
- B. Use a cuff with a width that is about 60% of the client's arm circumference.
- C. Have the client sit with their arm resting at the level of their heart.
- D. Release the pressure on the client's arm at a rate of 5 to 6 mm per second.
Correct answer: A
Rationale: The correct action when checking a client's blood pressure is to apply the cuff above the client's antecubital fossa. Placing the cuff above this area allows for an accurate measurement of blood pressure. Choice B is incorrect because the cuff width should be approximately 40% of the arm circumference, not 60%. Choice C is incorrect as the client's arm should rest at heart level, not above it, to ensure an accurate reading. Choice D is incorrect as the pressure on the client's arm should be released at a rate of 2 to 3 mm per second, not 5 to 6 mm per second.
