1. A client has a new prescription for parenteral nutrition (PN) in 20% dextrose and fat emulsions. Which of the following is an appropriate action to include in the plan of care?
- A. Monitor blood glucose levels daily.
- B. Change the PN infusion bag every 24 hours.
- C. Prepare the client for a central venous line.
- D. Administer the PN and fat emulsion together.
Correct answer: C
Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.
2. A child with a diagnosis of nephrotic syndrome is under the care of a nurse. What is the priority nursing intervention?
- A. Administering diuretics
- B. Monitoring urine output
- C. Administering corticosteroids
- D. Restricting fluid intake
Correct answer: B
Rationale: The priority nursing intervention when caring for a child with nephrotic syndrome is to monitor urine output. This is essential to assess kidney function and evaluate the effectiveness of treatment. Administering diuretics (Choice A) may be a part of the treatment plan but should not be the priority over monitoring urine output. Administering corticosteroids (Choice C) is a common treatment for nephrotic syndrome, but monitoring urine output takes precedence. Restricting fluid intake (Choice D) may be necessary in some cases, but it is not the priority intervention compared to monitoring urine output.
3. The nurse is caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?
- A. Bed rest with bathroom privileges only
- B. Frequent, short walks with assistance
- C. Range of motion exercises to the knee every four hours
- D. Leg elevation to reduce swelling
Correct answer: B
Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
4. A visitor comes to the nursing station and tells the nurse that a client and his relative had a fight, and that the client is now lying unconscious on the floor. What is the most important action the LPN/LVN needs to take?
- A. Ask the client if he is okay.
- B. Call security from the room.
- C. Find out if there is anyone else in the room.
- D. Ask security to make sure the room is safe.
Correct answer: D
Rationale: The most critical action for the LPN/LVN to take in this situation is to ask security to ensure the room is safe. This step is crucial to prevent any further harm to the unconscious client or others. While it is important to assess the client's condition, ensuring safety takes precedence. Calling security from the room may expose the LPN/LVN to potential danger without confirming the safety of the environment first. Finding out if anyone else is in the room can wait until safety is established to avoid unnecessary risks.
5. A client with diabetes mellitus is scheduled for surgery. What is the most important preoperative instruction the nurse should provide?
- A. Take your insulin as usual
- B. Do not eat or drink after midnight
- C. Monitor your blood glucose closely
- D. Bring your glucose meter to the hospital
Correct answer: B
Rationale: The most important preoperative instruction for a client with diabetes mellitus scheduled for surgery is to instruct them not to eat or drink after midnight. This instruction is crucial to maintain NPO (nothing by mouth) status before surgery, reducing the risk of aspiration during anesthesia. While taking insulin as usual (Choice A) is important, doses can be adjusted by the healthcare team. Monitoring blood glucose closely (Choice C) is essential but not as critical preoperatively. Bringing a glucose meter to the hospital (Choice D) can be helpful but is not as vital as maintaining NPO status.
