Nursing Elites

1. Which type of cell is responsible for producing antibodies in the immune system?

• A. B lymphocytes
• B. T lymphocytes
• C. Macrophages
• D. Neutrophils

Correct answer: A

Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.

2. The PN identifies an electrolyte imbalance, exhibited by changes in mental status, and an elevated blood pressure for a client with progressive heart disease. Which intervention should the PN implement first?

• A. Record usual eating patterns
• B. Evaluate for muscle cramping
• C. Document abdominal girth
• D. Elevate both legs on pillows

Correct answer: B

Rationale: Evaluating for muscle cramping, which is a sign of electrolyte imbalance, is crucial in this scenario. Electrolyte imbalances, especially involving potassium or calcium, can lead to serious complications such as arrhythmias or seizures, which need immediate attention. Recording eating patterns (choice A) may be important for overall assessment but is not the priority in this situation. Documenting abdominal girth (choice C) and elevating legs on pillows (choice D) are not directly related to addressing the immediate concern of electrolyte imbalance and its potential complications.

3. The practical nurse is caring for a client whose urine drug screen is positive for cocaine. Which behavior is this client likely to exhibit during cocaine withdrawal?

• A. Elevated energy level
• B. Euphoria
• C. High self-esteem
• D. Powerful craving for more

Correct answer: D

Rationale: The correct answer is D: Powerful craving for more. During cocaine withdrawal, individuals often experience intense cravings for the drug, along with symptoms such as fatigue, depression, and anxiety. These cravings can be overpowering and lead to a strong desire to seek out more cocaine to alleviate the withdrawal symptoms. Choices A, B, and C are incorrect as elevated energy level, euphoria, and high self-esteem are more associated with the effects of cocaine rather than withdrawal symptoms. Withdrawal from cocaine is characterized by the opposite, such as fatigue, low mood, and intense cravings.

4. An 8-year-old is placed in 90-90 traction for a fractured femur resulting from a motor vehicle collision. Which finding requires further action by the nurse?

• A. No bowel movement for two days
• B. Mother assists child in changing positions
• C. Weights are touching the foot of the bed
• D. Child is able to move the toes freely when tickled

Correct answer: C

Rationale: The correct answer is C. In 90-90 traction, the weights should hang freely and not touch the foot of the bed to maintain proper traction and bone alignment. Option A is not necessarily a concern as bowel movements can be influenced by various factors, including diet changes and pain medication. Option B indicates good caregiver involvement, promoting comfort and preventing complications. Option D demonstrates neurovascular function, which is a positive finding. Therefore, the weights touching the foot of the bed is the finding that requires immediate attention to ensure the effectiveness of the traction.

5. A client on bedrest refuses to wear the prescribed pneumatic compression devices after surgery. Which action should the PN implement in response to the client's refusal?

• A. Emphasize the importance of active foot flexion
• B. Check the surgical dressing
• C. Complete an incident report
• D. Explain the use of an incentive spirometer every 2 hours

Correct answer: A

Rationale: The correct action for the PN to implement when a client refuses pneumatic compression devices is to emphasize the importance of active foot flexion. Active foot flexion exercises can help prevent deep vein thrombosis (DVT) in clients who are not using the compression devices. Encouraging some form of circulation-promoting activity is crucial to reduce the risks associated with immobility. Checking the surgical dressing (Choice B) is important but not the immediate action to address the refusal of compression devices. Completing an incident report (Choice C) is not necessary in this situation as the client's refusal is not an incident. Explaining the use of an incentive spirometer (Choice D) is not directly related to addressing the refusal of compression devices for DVT prevention.
