Nursing Elites

1. 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.

2. A homeless male client with a history of alcohol abuse had a CVA 10 years ago that resulted in left hemiparesis. Today he is brought to the clinic reporting pain in his left leg. He is afebrile, has 4+ pitting edema in the lower left leg, and has minimal swelling of the right leg. Which action should the PN implement first?

• A. Obtain a blood alcohol test
• B. Inspect legs for infection or trauma
• C. Complete a mental status exam
• D. Inquire about dietary salt intake

Correct answer: B

Rationale: Inspecting the legs for infection or trauma is the priority to assess the cause of the pain and edema, which could indicate deep vein thrombosis or cellulitis. Checking for signs of infection or trauma is crucial in this scenario to rule out potentially serious conditions. Obtaining a blood alcohol test, completing a mental status exam, or inquiring about dietary salt intake can be considered after addressing the immediate concern of identifying any infection or trauma in the leg.

3. A client presents to the office with complaints of swelling in the legs, chills, and shortness of breath. During auscultation of the chest, a heart murmur is heard. The client's blood culture reveals a microorganism in the blood. When a microorganism is found in the blood, this condition is called

• A. Bacteremia
• B. Sepsis
• C. Septicemia
• D. Parasitic infection

Correct answer: A

Rationale: When a microorganism is found in the blood, this condition is called bacteremia, which refers to the presence of bacteria in the bloodstream, as indicated by a positive blood culture. If not appropriately treated, bacteremia can progress to septicemia, also known as sepsis. Sepsis is a severe and life-threatening response to an infection, characterized by systemic inflammation and organ dysfunction. Parasitic infections involve pathogens other than bacteria and are not directly related to the scenario described.

4. When preparing a sterile field for a procedure, which action should the nurse take to maintain sterility?

• A. Place sterile items around the sterile field
• B. Keep hands below waist level to avoid contamination
• C. Open the sterile package away from the body
• D. Avoid reaching over the sterile field

Correct answer: D

Rationale: To maintain sterility when preparing a sterile field, it is essential to avoid reaching over the sterile field. This action can introduce contaminants from the nurse's clothing or unsterile areas, compromising the sterility of the field. Placing sterile items around the sterile field (choice A) is incorrect as it may increase the risk of contamination by extending the area where non-sterile items may come in contact. Keeping hands below waist level (choice B) is also incorrect as it does not prevent contamination effectively. Opening the sterile package away from the body (choice C) is incorrect since it exposes the contents to the nurse's body, which is not sterile.

5. What intervention should the PN implement when taking the rectal temperature of an adult client?

• A. Lubricate the tip of the thermometer with a water-based gel.
• B. Gently insert the thermometer 1 inch into the rectum.
• C. Hold the thermometer in place the entire time while taking the temperature.
• D. Place the client in the left lateral position.

Correct answer: C

Rationale: When taking a rectal temperature, it is essential to hold the thermometer in place the entire time to ensure safety, accuracy, and prevent the thermometer from slipping out. Choice A, lubricating the tip of the thermometer with a water-based gel, is important for comfort and ease of insertion. Choice B, gently inserting the thermometer 1 inch into the rectum, is more accurate for adults than inserting it 3 inches. Choice D, placing the client in the left lateral position, is not necessary for a rectal temperature measurement.
