Nursing Elites

1. 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.

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. The nurse is caring for a woman 2 hours after a vaginal delivery. Documentation indicates that the membranes were ruptured for 36 hours prior to delivery. What are the priority nursing diagnoses at this time?

• A. Altered tissue perfusion
• B. Risk for fluid volume deficit
• C. High risk for hemorrhage
• D. Risk for infection

Correct answer: D

Rationale: The correct answer is 'Risk for infection.' When membranes are ruptured for over 24 hours before delivery, there is a significantly increased risk of infection for both the mother and the newborn. Factors such as increased local cytokines, an imbalance in enzyme activity, and increased intrauterine pressure contribute to this risk. 'Altered tissue perfusion' is not the priority in this scenario as there is no indication of compromised blood flow. 'Risk for fluid volume deficit' is not the priority as there are no signs of excessive fluid loss. 'High risk for hemorrhage' is not the priority as the question does not suggest active bleeding as an immediate concern.

4. 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.

5. Mr. K is admitted to the orthopedic unit one morning in preparation for a total knee replacement to start in two hours. Which of the following is a priority topic to instruct this client on admission?

• A. The approximate length of the surgery
• B. The type of anticoagulants that will be prescribed
• C. The time of the next meal of solid food
• D. The length of time until the client can return to work

Correct answer: A

Rationale: The priority topic to instruct a client admitted for a total knee replacement surgery should be the approximate length of the surgery. Pre-surgical teaching should focus on preparing the client for the upcoming procedure. Providing information about the duration of the surgery can help manage the client's expectations, reduce anxiety, and ensure they are mentally prepared for the operation. While details about post-operative care, anticoagulants, meals, and return to work are important, they are not the immediate priority during the preoperative phase. These aspects can be addressed at a later stage in the client's care journey.
