Nursing Elites

1. 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.

2. If you are caring for a patient of the Hindu culture, what may you anticipate regarding visitors?

• A. Limited visitors, respectful of privacy
• B. Family members only
• C. Large number of visitors/community support
• D. None of the above

Correct answer: C

Rationale: In Hindu culture, there is a strong sense of community and support. It is common for a patient to receive a large number of visitors, indicative of the community coming together to provide emotional and practical support. This support network is crucial for the patient's well-being and healing process. Option A, limited visitors, is incorrect as the Hindu culture values community involvement. Option B, family members only, is incorrect as the support network extends beyond just family. Option D, none of the above, is incorrect as the Hindu culture typically involves community support and a significant number of visitors.

3. 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.

4. Upon admission to the stroke care unit of a rehabilitation center, what is the primary action of the nurse?

• A. Collect and organize documents for the client's medical record
• B. Prepare the client's identification bracelet
• C. Identify pertinent health history data and current needs and limitations
• D. Gather the client's valuables and secure them in a locked container

Correct answer: C

Rationale: When a client is admitted to a stroke care unit in a rehabilitation center, the nurse's initial priority is to assess the client. This assessment includes identifying relevant health history data that may impact the client's care. By recognizing the client's current needs and limitations, the nurse can develop a comprehensive understanding of the client's condition. This information is crucial for generating a nursing diagnosis and establishing appropriate care outcomes. While collecting and organizing documents for the medical record, preparing identification bracelets, and securing valuables are important tasks, they are not the primary actions that directly influence the client's immediate care upon admission.

5. The healthcare professional needs to validate which of the following statements pertaining to an assigned client?

• A. The client has a hard, raised, red lesion on his right hand.
• B. A weight of 185 lbs. is recorded in the chart.
• C. The client reported an infected toe.
• D. The client's blood pressure is 124/70.

Correct answer: C

Rationale: Validation is the process of confirming that data are actual and factual. Data that can be measured can be accepted as factual, as in options 1, 3, and 4. The weight, blood pressure, and physical appearance of a lesion can be objectively verified. However, option C, the client reporting an infected toe, requires the nurse to directly assess the client's toe to confirm the statement. This choice involves subjective data that needs to be validated through direct observation, making it the correct answer. Options A, B, and D provide data that can be measured objectively and verified without the need for further assessment.
