Nursing Elites

1. A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?

• A. Contain histamine and provide protection during allergic reactions
• B. Are involved in phagocytosis
• C. Provide protection and immunity against foreign substances
• D. Carry hemoglobin and oxygen to body tissues

Correct answer: C

Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue. Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes. Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages. Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.

2. Which of these statements best describes the characteristics of an effective reward feedback system?

• A. Specific feedback is given as close to the event as possible
• B. Staff is given feedback in equal amounts over time
• C. Positive statements precede negative statements
• D. Performance goals should be higher than what is attainable

Correct answer: A

Rationale: The correct answer is that specific feedback should be given as close to the event as possible in an effective reward feedback system. This is important because feedback is most useful when provided immediately. Giving feedback promptly reinforces positive behavior and helps in modifying problem behaviors. Providing feedback close to the event helps in ensuring that standards are clearly understood and can be met. Choices B, C, and D are incorrect because staff should not be given feedback in equal amounts over time, positive statements do not necessarily have to precede negative statements, and setting performance goals higher than what is attainable can lead to demotivation and decreased performance.

3. At the beginning of her shift in a long-term care facility, which of the following clients should a nurse check on first?

• A. A 91-year-old man who needs help eating breakfast
• B. An 86-year-old man who has been incontinent in his bed
• C. An 82-year-old woman who needs IV antibiotics
• D. A 75-year-old man who is recovering from an injury and needs an ice pack

Correct answer: C

Rationale: When prioritizing care in a long-term care facility, the nurse must consider tasks that require their immediate attention and cannot be delegated. Administering IV antibiotics is a critical nursing task that only the nurse can perform, ensuring the timely and correct delivery of medication to the patient. While assisting with breakfast, managing incontinence, and providing an ice pack are important, these tasks can be delegated to other healthcare team members, allowing the nurse to address the client needing IV antibiotics first to ensure effective treatment and patient safety.

4. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

5. You are attempting to teach the wife of a Greek patient how to administer his gastrostomy tube feedings once he returns home. She smiles and nods through your explanations, but when you ask her for a return demonstration, she looks confused and shakes her head. Her daughter enters the room and states that she does not speak English. What would be most helpful in this situation?

• A. Teach the daughter instead
• B. Teach both and ask the daughter to translate for you
• C. Contact a home health agency to provide care
• D. Provide a pamphlet with detailed instructions

Correct answer: B

Rationale: Teaching both the patient's wife and the daughter is the best option in this situation. The daughter may not always be available, and the wife is eager to care for her husband at home. While a hospital interpreter is often preferred, asking the daughter to interpret is a good alternative. This approach allows the daughter to receive instruction and reinforce it for herself as she translates it to her mother. Contacting a home health agency may not be necessary if family members are willing and able to assist. Providing a pamphlet with detailed instructions would not be as effective in ensuring the wife fully understands the procedure and can carry it out correctly.
