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 client is post-operative day two from a total hip arthroplasty. The nurse notices the surgical wound is red and warm to the touch. What is the most appropriate action?

• A. Apply an ice pack to the incision site.
• B. Monitor the client's temperature.
• C. Document the findings and continue to monitor.
• D. Notify the healthcare provider.

Correct answer: D

Rationale: The correct action when a nurse notices redness and warmth at the surgical wound post total hip arthroplasty is to notify the healthcare provider. These signs may indicate an infection, and prompt evaluation by the healthcare provider is crucial to initiate appropriate treatment. Applying an ice pack (Choice A) may not address the underlying issue of a potential infection. Monitoring the client's temperature (Choice B) is important but not the priority when signs of infection are present. Documenting the findings and continuing to monitor (Choice C) is necessary but should be accompanied by notifying the healthcare provider for further assessment and intervention.

3. A client is recovering from a craniotomy and has a ventriculostomy in place. The nurse notices the drainage from the ventriculostomy is suddenly increasing. What should the nurse do first?

• A. Increase the head of the bed to 45 degrees.
• B. Clamp the ventriculostomy tube.
• C. Notify the healthcare provider immediately.
• D. Measure the client's head circumference.

Correct answer: C

Rationale: A sudden increase in drainage from a ventriculostomy could indicate a serious complication such as increased intracranial pressure or hemorrhage. The priority action in this situation is to notify the healthcare provider immediately to ensure prompt evaluation and intervention. Increasing the head of the bed may be beneficial in some situations but is not the first action to take. Clamping the ventriculostomy tube is inappropriate as it can lead to increased intracranial pressure. Measuring the client's head circumference is not the priority when there is a sudden increase in ventriculostomy drainage.

4. During a blood transfusion, which sign or symptom should prompt the healthcare provider to immediately stop the transfusion?

• A. Slight increase in blood pressure
• B. Elevated temperature and chills
• C. Mild nausea
• D. Slight headache

Correct answer: B

Rationale: The correct answer is B: Elevated temperature and chills. These symptoms are indicative of a transfusion reaction, which can be severe and life-threatening. It is crucial to stop the transfusion immediately and notify the healthcare provider for further assessment and management. Elevated temperature and chills are classic signs of a transfusion reaction, specifically indicating a possible febrile non-hemolytic reaction. Choice A, a slight increase in blood pressure, is not typically a reason to stop a transfusion unless it is a significant sudden increase. Mild nausea (Choice C) and a slight headache (Choice D) are common side effects of blood transfusions and are not primary indicators of a transfusion reaction that require immediate cessation of the transfusion.

5. What is the primary function of surfactant in the lungs?

• A. Reduce surface tension
• B. Enhance oxygen absorption
• C. Facilitate carbon dioxide release
• D. Increase lung volume

Correct answer: A

Rationale: The primary function of surfactant in the lungs is to reduce surface tension in the alveoli. This reduction in surface tension prevents lung collapse and allows for easier breathing. It is particularly crucial in premature infants to help with lung expansion. Choice B is incorrect because surfactant primarily affects surface tension, not oxygen absorption. Choice C is incorrect because surfactant's main role is not in facilitating carbon dioxide release. Choice D is incorrect because surfactant does not directly increase lung volume; its main role is in reducing surface tension.
