1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. 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.

3. Because of budget cuts in the hospital, the nursing manager informs the staff that they must either rotate to other units more often or take their turns staying home from work. Which principle is this nurse manager demonstrating?

• A. Justice
• B. Paternalism
• C. Veracity
• D. Fraternity

Correct answer: D

Rationale: Veracity involves truth-telling, even in challenging situations. In this scenario, the nurse manager is being transparent about the need for staff to rotate units or take turns staying home due to budget cuts. This allows the staff to make informed decisions about their work schedules and potential impact on their pay and work areas. Option A, Justice, does not apply as the focus is on communication and transparency, not fairness. Option B, Paternalism, does not fit as it involves decisions made for others' well-being without their input, which is not the case here. Option D, Fraternity, pertains to unity among individuals, which is not the principle demonstrated by the nurse manager in this situation.

4. The nurse is assessing a 3-year-old child for symptoms of autism spectrum disorder (ASD). Which assessment finding should lead the nurse to question the diagnosis?

• A. Inability to react appropriately to social cues
• B. Engages in repetitive behaviors
• C. Comprehends language well beyond the complexity expected for age
• D. Displays self-destructive behavior

Correct answer: C

Rationale: The correct answer is 'Comprehends language well beyond the complexity expected for age.' Children with autism spectrum disorder typically struggle with language and communication skills, so comprehending language well beyond their age level would not align with the diagnosis of ASD. This finding could indicate other developmental strengths or delays. Choices A, B, and D are more commonly associated with ASD - the inability to react appropriately to social cues, engaging in repetitive behaviors, and displaying self-destructive behavior are typical manifestations of autism spectrum disorder.

5. A nurse is providing dismissal instructions for a child who was admitted for rotavirus. Which of the following statements by the parent indicates the need for further teaching?

• A. I'll start giving him his antibiotics as soon as we get home.
• B. I will call the physician if he becomes dizzy or overly fussy.
• C. He will need to wash his hands a lot to keep this from spreading.
• D. I'll watch to see when he stops having diarrhea stools.

Correct answer: A

Rationale: The correct answer is 'I'll start giving him his antibiotics as soon as we get home.' Rotavirus is a viral illness, and antibiotics are ineffective for its treatment. The parent's statement indicates a need for further teaching as antibiotics are not appropriate for treating rotavirus. Option B is correct as it demonstrates the parent's understanding of when to contact the physician for concerning symptoms. Option C is a correct statement regarding infection control practices. Option D is also correct as monitoring diarrhea stools is essential to track recovery from rotavirus.
