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. Which action represents the evaluation stage of the plan of care?

• A. The nurse assigns a nursing diagnosis of Impaired Skin Integrity related to diminished skin circulation
• B. The nurse assesses the client's vital signs and asks about symptoms
• C. The nurse determines that the client is not meeting his set outcomes and makes revisions
• D. The nurse discusses the client's health history

Correct answer: C

Rationale: The correct answer is C. The evaluation stage of the nursing process involves reviewing the assessments, diagnoses, and interventions given to the client and then determining if the client is meeting expected outcomes. In this scenario, the nurse is assessing whether the client is meeting the outcomes set for their care plan and making revisions as needed. Choice A is incorrect as assigning a nursing diagnosis is part of the nursing diagnosis phase, not the evaluation phase. Choice B represents the assessment phase of the nursing process, not the evaluation phase. Choice D involves discussing the client's health history, which is more aligned with the assessment phase rather than the evaluation phase.

3. Which of the following components is associated with hypertonic dehydration?

• A. Plasma sodium levels above 150 mEq/L
• B. Fluid moves from extracellular space to intracellular space
• C. Water loss is greater than electrolyte loss
• D. Physical signs and symptoms are grossly apparent

Correct answer: C

Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.

4. Research participants are involved in a trial that incidentally separates them into two groups. One group receives an intervention, while the other group does not. Both groups are compared for outcomes. What type of research method is this?

• A. Experimental design
• B. Double-blind experiment
• C. Randomized controlled trial
• D. Repeated measures design

Correct answer: C

Rationale: A randomized controlled trial is a research method in which participants are randomly assigned to either a treatment or control group. This design helps eliminate bias and allows for the comparison of outcomes between the two groups. In this scenario, where participants are separated into intervention and non-intervention groups for comparison, it aligns with the characteristics of a randomized controlled trial. The key feature distinguishing it from the other options is the random assignment of participants to groups, ensuring that both groups are comparable at the start of the study. Double-blind experiments involve blinding both participants and researchers to treatment allocation, which is not explicitly mentioned in the scenario. Experimental design refers to a broader category that includes various types of research designs beyond just randomized controlled trials. Repeated measures design involves collecting multiple observations from the same participants over time, which is not the case described in the scenario.

5. A writer is admitted for the second time accompanied by his wife. He is demanding, arrogant, talks fast, and is hyperactive. Initially, the nurse should plan this for a manic client:

• A. Set realistic limits to the client's behavior
• B. Repeat verbal instructions as often as needed
• C. Allow the client to express feelings to relieve tension
• D. Assign a staff member to be with the client at all times to help maintain control

Correct answer: A

Rationale: For a manic client who is demanding, arrogant, talks fast, and is hyperactive, setting realistic limits to the client's behavior is essential to ensure safety as manic clients may engage in injurious activities. A quiet environment and consistent, firm limits help to maintain control. While repeating verbal instructions may be necessary due to distractibility, it is not the priority compared to setting limits for safety. Allowing the client to express feelings is important, but only non-destructive methods of expression should be permitted. Assigning a staff member to be with the client at all times is not a realistic approach as it may not always be feasible or necessary for managing manic behavior effectively.
