Nursing Elites

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. At the beginning of the shift, a nurse receives report for her daily assignment. Which of the following situations should the nurse give first priority?

• A. A diabetic client with a blood glucose level of 195 mg/dL
• B. A family member of an elderly client who has questions
• C. A client with COPD with an oxygen saturation of 84%
• D. A client who requires assistance to use the bathroom

Correct answer: C

Rationale: When prioritizing the needs of clients, the nurse must begin with the unstable client or manage conditions that affect airway, breathing, or circulation first. The client with COPD has a condition that affects breathing and is exhibiting decreased oxygen saturation levels; therefore, this client should be the first priority. Option A, the diabetic client with a blood glucose level of 195 mg/dL, does not present an immediate threat to airway, breathing, or circulation. Option B, addressing questions from a family member, is important but can be addressed after addressing critical patient needs. Option D, assisting a client to use the bathroom, is a routine task that can be prioritized after addressing urgent medical needs.

3. 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.

4. The client is receiving an MAOI. Which foods should the nurse caution the client to avoid?

• A. Pork, spinach, and fresh oysters
• B. Milk, grapes, and meat tenderizers
• C. Cheese, beer, and products with chocolate
• D. Leafy green vegetables, fresh apples, and ice cream

Correct answer: C

Rationale: The correct answer is C. When a client is receiving a monoamine oxidase inhibitor (MAOI), they should avoid foods high in tyramine to prevent a hypertensive crisis. Cheese, beer, and products with chocolate are rich in tyramine and can interact with MAOIs, leading to a dangerous rise in blood pressure. Choices A, B, and D do not contain high levels of tyramine and are not typically restricted when taking MAOIs.

5. Which of the following conditions increases a client's risk of aspiration of stomach contents?

• A. A client is in restraints
• B. A client has a scaphoid abdomen
• C. A client is lying prone
• D. More than one answer is correct

Correct answer: A

Rationale: A client in restraints is at an increased risk of aspiration of stomach contents. When a client is restrained, they may be unable to effectively move or turn their body if they begin to vomit, which can lead to aspiration. This lack of mobility can hinder their ability to protect their airway. On the other hand, a scaphoid abdomen, which is sunken or hollowed, is not a direct risk factor for aspiration. Additionally, lying prone, facing downward, does not necessarily increase the risk of aspiration, as aspiration is more likely when lying supine (facing upward). Therefore, the correct answer is that a client is in restraints.
