1. Which is the most important safety measure when administering a medication through a patient’s central venous catheter (CVC)?

• A. Using a sterile technique
• B. Ensuring correct placement of the CVC
• C. Flushing the CVC with saline after administration
• D. Monitoring for signs of infection

Correct answer: B

Rationale: The most important safety measure when administering a medication through a patient’s central venous catheter (CVC) is ensuring the correct placement of the CVC. This is crucial to prevent complications such as extravasation, infection, or improper drug delivery. While using a sterile technique, flushing the CVC with saline after administration, and monitoring for signs of infection are all important aspects of CVC care, ensuring the correct placement of the catheter takes precedence as it directly impacts patient safety during medication administration.

2. The nurse and UAP enter a client's room and find the client lying on the bed. The nurse determines that the client is unresponsive. Which instruction should the nurse give the UAP first?

• A. Obtain emergency help
• B. Feel for a carotid pulse
• C. Bring a glucometer to the room
• D. Check the blood pressure

Correct answer: A

Rationale: The correct answer is to instruct the UAP to obtain emergency help first. In a situation where a client is unresponsive, the priority is to ensure that help is summoned promptly. This allows for the availability of necessary resources and assistance for resuscitation or other emergency interventions. Feeling for a carotid pulse or checking the blood pressure can be important assessments but are secondary to obtaining immediate help. Bringing a glucometer to the room, while relevant in certain situations, is not the priority when the client's unresponsiveness indicates a need for urgent intervention.

3. A client post-mastectomy is concerned about the risk of lymphedema. What should the nurse include in the discharge instructions to minimize this risk?

• A. Wear compression garments on the affected arm.
• B. Avoid venipunctures and blood pressure measurements on the affected arm.
• C. Perform vigorous exercises to strengthen the affected arm.
• D. Keep the affected arm elevated at all times.

Correct answer: B

Rationale: To minimize the risk of lymphedema after a mastectomy, it is essential to instruct the client to avoid venipunctures and blood pressure measurements on the affected arm. These procedures can lead to trauma or impede lymphatic flow, increasing the risk of lymphedema. Wearing compression garments helps manage lymphedema but is not preventive. Performing vigorous exercises can strain the affected arm and increase the risk of lymphedema. Keeping the affected arm elevated at all times is unnecessary and not an effective preventive measure against lymphedema.

4. What is the best thing to say to a patient scheduled for cataract surgery who is concerned that the physician works on the correct eye?

• A. You are wearing an ID bracelet that will let the medical team know which eye to work on.
• B. When you are taken to the surgery area, the medical staff will confirm which eye needs the surgery.
• C. The surgeon will mark the correct eye before the cataract surgery based on your medical records.
• D. You will wear an ID bracelet, and the nurse will verify the eye scheduled for surgery by comparing it with your records and marking it with a permanent marker.

Correct answer: D

Rationale: The best response reassures the patient by explaining the process of verifying and marking the correct eye, a safety measure to prevent wrong-site surgery, directly addressing the patient’s concern. Choice A is close but implies the ID bracelet alone determines the correct eye, missing the verification process. Choice B talks about confirmation but lacks details about marking the correct eye. Choice C mentions the surgeon's record but does not specify the direct verification and marking process, unlike Choice D.

5. Which type of cell is responsible for producing antibodies in the immune system?

• A. B lymphocytes
• B. T lymphocytes
• C. Macrophages
• D. Neutrophils

Correct answer: A

Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.
