HESI Quizlet Fundamentals
1. The client is being taught how to self-administer a subcutaneous injection. To ensure sterility of the procedure, which subject is most important for the instructor to include in the teaching plan?
- A. Hand washing before preparing the injection.
- B. Technique for drawing medication from a vial.
- C. Selection and rotation of injection sites.
- D. Proper disposal of injection equipment.
Correct answer: B
Rationale: To maintain the sterility of the procedure, it is crucial to teach the client the correct technique for drawing medication from a vial. This ensures that the medication remains sterile during preparation and administration. While hand washing, injection site selection, and equipment disposal are important aspects of injection safety, the key focus should be on maintaining the sterility of the medication itself to prevent infections and ensure the effectiveness of the treatment.
2. The home health nurse provides teaching about insulin self-injection to a client who was recently diagnosed with diabetes mellitus. When the client begins to perform a return demonstration of an insulin injection into the abdomen, which instruction should the nurse provide?
- A. Select a different injection site
- B. Continue with the insulin injection
- C. Keep the skin flat rather than bunched
- D. Lie down flat for better skin exposure
Correct answer: B
Rationale: Choosing to continue with the insulin injection is the correct instruction in this scenario because it allows the client to demonstrate proper technique and reinforces their learning. Selecting a different injection site (choice A) is not necessary if the client is injecting into the abdomen as it is a suitable site. Keeping the skin flat rather than bunched (choice C) is a good practice but is not the priority in this situation where the client is demonstrating the injection technique. Lying down flat for better skin exposure (choice D) is not required and may not be practical for the client during routine self-injections.
3. A 2-year-old child is admitted with severe dehydration due to gastroenteritis. Which assessment finding indicates that the child's condition is improving?
- A. Decreased heart rate.
- B. Sunken fontanelle.
- C. Increased urine output.
- D. Dry mucous membranes.
Correct answer: C
Rationale: Increased urine output is a positive sign indicating that the child's hydration status is improving. It suggests that the kidneys are functioning more effectively and able to excrete urine, which is a crucial indicator of improved hydration levels in a dehydrated patient. Decreased heart rate (Choice A) can be a sign of possible shock. A sunken fontanelle (Choice B) is a sign of dehydration. Dry mucous membranes (Choice D) are also indicative of dehydration.
4. A 5-week-old infant with hypertrophic pyloric stenosis has developed projectile vomiting over the last two weeks. Which intervention should the nurse plan to implement?
- A. Instruct the mother to give sugar water only.
- B. Offer the infant oral rehydration every 2 hours.
- C. Provide Pedialyte feedings via nasogastric tube.
- D. Maintain intravenous fluid therapy.
Correct answer: D
Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.
5. An adult client with a broken femur reports muscle spasms. What action should the nurse implement while awaiting surgery?
- A. Check the client's most recent electrolyte levels.
- B. Administer a PRN dose of muscle relaxant.
- C. Reduce the weight on the traction device.
- D. Encourage oral fluid intake to relieve muscle tension.
Correct answer: D
Rationale: The correct action for the nurse to implement while awaiting surgery for a client with muscle spasms due to a broken femur is to encourage oral fluid intake to relieve muscle tension. Dehydration can exacerbate muscle spasms, so increasing fluid intake can help alleviate them. Checking electrolyte levels may not directly address muscle spasms in this situation. Administering a muscle relaxant should be based on a healthcare provider's prescription, and traction weight adjustments should only be made by the provider overseeing the client's care.
