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 A male client who has been diagnosed with schizophrenia is withdrawn, isolates himself in the day room, and answers questions with one or two-word responses. This morning, the practical nurse observes that he is diaphoretic and is pacing in the hall. Which intervention is most important for the PN to implement?

• A. Persuade the client to lie down
• B. Provide a drink high in electrolytes
• C. Observe the client during the shift
• D. Measure appropriate vital signs

Correct answer: D

Rationale: Measuring vital signs is crucial in this situation as it helps to determine if the client is experiencing a physical health issue or if the symptoms are related to a mental health crisis, such as anxiety or agitation. The presence of diaphoresis and pacing may indicate physiological changes requiring immediate attention. Providing a drink high in electrolytes or persuading the client to lie down may not address the underlying cause of the symptoms. Simply observing the client during the shift without taking necessary actions to assess his physiological status may delay appropriate intervention.

3. A Native American client is admitted with a diagnosis of psychosis not otherwise specified. The client's family seems to regard the client's hallucinations as normal. What assessment can be made?

• A. The client's family regards the hallucinations from a cultural context
• B. The client will benefit from a talking circle
• C. The client will need a medicine man
• D. The client will need a single room

Correct answer: A

Rationale: Choice A is correct because the family may interpret the client's hallucinations through their cultural lens, potentially viewing them as normal or spiritually significant. Understanding and acknowledging the cultural context is essential for providing culturally sensitive care. Choices B, C, and D are incorrect because while talking circles and seeking guidance from a medicine man may be culturally relevant interventions in some contexts, the priority in this situation is to recognize and respect the family's perspective on the client's hallucinations.

4. 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.

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.
