1. A client has a prescription for 5 units of regular insulin and 10 units of NPH insulin to mix together and administer subcutaneously. Determine the correct order of steps for this procedure.
- A. Inject 5 units of air into the bottle of regular insulin
- B. Withdraw the correct dose of NPH insulin from the bottle
- C. Inject 10 units of air into the bottle of NPH insulin
- D. Withdraw the correct dose of regular insulin from the bottle
Correct answer: B
Rationale: The correct order of steps for this procedure is to first inject air into the NPH insulin bottle to prevent vacuum formation. After injecting air into the NPH insulin, the next step is to withdraw the correct dose of regular insulin from its bottle. This sequence ensures that the regular insulin is drawn after the NPH insulin, preventing contamination and ensuring accurate dosing. Therefore, choice B is correct. Choices A, C, and D are incorrect because air should be injected into the NPH insulin first, not the regular insulin, and the doses should be withdrawn in the appropriate order to maintain the integrity and potency of each insulin type.
2. The client has a nasogastric (NG) tube in place for decompression. What action should the LPN/LVN take to maintain patency of the NG tube?
- A. Irrigate the tube with normal saline every shift.
- B. Check the tube placement by auscultation.
- C. Secure the tube to the client's gown.
- D. Flush the tube with 5 mL of sterile water before and after medication administration.
Correct answer: A
Rationale: To maintain patency of the NG tube, it is essential to irrigate the tube with normal saline every shift. This action helps prevent clogging and ensures that the tube remains clear for effective decompression. Checking tube placement by auscultation (Choice B) is important for verifying correct placement but does not directly impact patency. Securing the tube to the client's gown (Choice C) is crucial for safety and comfort but is not directly related to maintaining patency. Flushing the tube with sterile water before and after medication administration (Choice D) is not the recommended method for maintaining patency of an NG tube, as normal saline is the appropriate solution for this purpose.
3. What will ensure the safe movement of a patient who is unable to move and needs to be pulled up in bed?
- A. Place the pillow under the patient's head and shoulders.
- B. Attempt to do it alone if the bed is in a flat position.
- C. Place the side rails in the up position.
- D. Use a friction-reducing device.
Correct answer: D
Rationale: To ensure the safe movement of a patient who is unable to move and needs to be pulled up in bed, it is essential to use a friction-reducing device. This device helps reduce the risk of injury to both the patient and the healthcare provider by minimizing the effort required to reposition the patient. Placing a pillow under the patient's head and shoulders (Choice A) may provide comfort but does not address the safety concerns associated with moving the patient. Attempting to move the patient alone (Choice B) is not recommended as it can lead to injuries for both the patient and the healthcare provider. Placing the side rails in the up position (Choice C) may not directly contribute to the safe movement of the patient in this scenario.
4. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?
- A. 8 mL/hr
- B. 10 mL/hr
- C. 12 mL/hr
- D. 15 mL/hr
Correct answer: A
Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.
5. A healthcare professional is preparing to administer an intramuscular injection to a young adult client. Which of the following injection sites is the safest for this client?
- A. Ventrogluteal
- B. Dorsogluteal
- C. Deltoid
- D. Vastus lateralis
Correct answer: A
Rationale: The ventrogluteal site is considered the safest for intramuscular injections in young adult clients due to its location away from major nerves and blood vessels. The ventrogluteal site is preferred over the dorsogluteal site, as the latter is associated with a higher risk of injury to the sciatic nerve. The deltoid site is commonly used for vaccines but may not be suitable for all intramuscular injections due to smaller muscle mass. The vastus lateralis site is often used in infants and young children, but in young adults, the ventrogluteal site is preferred for safety and efficacy.
