Administering medication intravenously allows for immediate entry into the bloodstream, leading to swift therapeutic effects. This method ensures that the drug reaches its intended site quickly and effectively, making it ideal for urgent medical needs.
A: Fewer adverse reactions noted. Adverse reactions can occur with any route of administration; intravenous methods do not inherently reduce their likelihood compared to other delivery systems.
B: Less costly to the client. The intravenous route often involves higher costs due to the need for specialized equipment, professional administration, and potential hospital stays, making it less economical.
D: Ease of maintaining drug therapy in the home setting. Intravenous therapy typically requires clinical oversight and challenging logistics, which complicates home administration compared to more manageable oral medications.
Question 23
Regular
The client asks the nurse why it is necessary to prime the intravenous tubing. Which is the best response by the nurse?
Correct!
Incorrect
The correct answer is: A
Rationale
Priming the intravenous tubing eliminates air and the potential for complications during infusion. This process ensures that the IV line is free of air bubbles, which can cause embolisms or other issues, promoting patient safety.
B: It helps to keep the catheter open and flowing. While maintaining flow is important, priming specifically addresses air removal, not just keeping the catheter patent.
C: It allows for air lock, which ensures the delivery of all the medication. Air lock is not beneficial; priming focuses on eliminating air to avoid interruptions in medication delivery.
D: It adheres to infection control and prevention of infection. Although infection prevention is crucial, priming primarily relates to air removal rather than infection control measures in IV therapy.

Question 24
Regular
The client has been receiving intravenous (IV) fluids for the last 6 hours and now is demonstrating bounding pulse, crackles in the lungs, leg swelling, and a blood pressure more than $15 \mathrm{~mm} \mathrm{Hg}$ higher than baseline. Which is the most likely nursing problem statement for this client?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Fluid overload. The client's symptoms of a bounding pulse, lung crackles, leg swelling, and elevated blood pressure indicate excessive fluid accumulation, which aligns with the diagnosis of fluid overload due to IV therapy.
A: Altered tissue perfusion. While tissue perfusion may be affected, the specific symptoms presented indicate a fluid balance issue rather than a direct perfusion problem.
B: Ineffective airway clearance. The presence of crackles suggests fluid in the lungs, but this does not equate to an inability to clear the airway effectively.
D: Altered skin integrity. Although fluid overload can affect skin condition, the primary concern in this scenario is the acute response to fluid excess rather than skin issues.

Question 25
Regular
The client is receiving total parenteral nutrition (TPN), and the solution bag is almost empty. The nurse discovers there are no containers prepared for use. The nurse contacts the healthcare provider. Which order would the nurse expect from the healthcare provider?
Correct!
Incorrect
The correct answer is: A
Rationale
Hang dextrose 10% in water (D10W) until new container is ready.
Using D10W maintains glucose supply and prevents hypoglycemia, which is crucial for patients dependent on TPN. It provides a temporary solution to ensure continuous nutrition and metabolic stability while waiting for the new TPN container.
B: Hang normal saline solution (NSS). NSS does not provide the necessary glucose and calories needed by a patient on TPN, risking potential metabolic complications during the wait.
C: Slow the rate to keep vein open (KVO) until new container is ready. KVO does not deliver any nutritional support and could lead to hypoglycemia, compromising the patient’s health during the delay.
D: Stop the infusion and then flush the catheter to maintain patency. Stopping the infusion entirely deprives the patient of essential nutrients, increasing the risk of adverse effects from abrupt discontinuation of TPN.

Question 26
Regular
A postoperative total hip replacement client is to receive salvaged blood through the cell saver system. The nurse is most concerned about which possible transfusion reaction?
Correct!
Incorrect
The correct answer is: D
Rationale
Septic reaction is the primary concern when administering salvaged blood through the cell saver system. Contamination during collection or processing can introduce pathogens, leading to serious infections postoperatively, especially in a surgical patient.
A: Incompatibility reaction Transfusion of salvaged blood typically involves the patient’s own blood, significantly minimizing the risk of incompatibility, making this option less relevant in the context of cell saver use.
B: Allergic reaction While allergic reactions can occur with transfusions, they are less likely with salvaged blood since it is autologous. The body's immune response to its own blood is generally minimal.
C: Hepatitis B The likelihood of hepatitis B transmission through salvaged blood is low, particularly when the blood is collected and processed under sterile conditions, reducing the risk of infection.

Question 27
Regular
A central venous catheter has been inserted in the right subclavian vein of the client. Which of the following would be the priority nursing action before total parenteral nutrition (TPN) can be started?
Correct!
Incorrect
The correct answer is: A
Rationale
A portable chest x-ray must be called to confirm proper placement of the central venous catheter in the right subclavian vein before initiating total parenteral nutrition (TPN).
A: A portable chest x-ray is essential for verifying catheter positioning, ensuring it is situated correctly within the vascular system, which is critical to prevent complications such as pneumothorax or improper infusion.
B: Assessing for swelling, redness, and drainage of the site focuses on local complications but does not confirm catheter placement, which is vital prior to starting TPN.
C: Allowing the TPN solution to warm to room temperature is a standard practice, yet it does not address the immediate need to verify the catheter's correct placement before administration.
D: Assessing blood sugar via a glucometer is important for monitoring patient safety, but it is not a priority before ensuring the central venous catheter is properly positioned for TPN.
