Nursing Elites

1. Which disorder is characterized by demyelination of neurons in the central nervous system?

• A. Multiple sclerosis
• B. Parkinson's disease
• C. Alzheimer's disease
• D. Huntington's disease

Correct answer: A

Rationale: Multiple sclerosis is the correct answer. It is an autoimmune disease that specifically targets and damages the myelin sheath surrounding neurons in the central nervous system. This demyelination disrupts the transmission of nerve signals and leads to a variety of neurological symptoms. Parkinson's disease (Choice B), Alzheimer's disease (Choice C), and Huntington's disease (Choice D) are neurodegenerative disorders that do not primarily involve demyelination of neurons in the CNS. Parkinson's disease is characterized by the loss of dopamine-producing neurons, Alzheimer's disease by the formation of plaques and tangles in the brain, and Huntington's disease by a genetic mutation affecting nerve cells.

2. The PN notes that a UAP is ambulating a male client who had a stroke and has right-sided weakness. The UAP is walking on the client's left side. Which action should the PN take?

• A. Instruct the UAP to walk on the client's affected side
• B. Take over the ambulation and provide guidance to the UAP immediately
• C. Provide the client with an assistive device, such as a cane or walker
• D. Tell the UAP to take the client back to his room

Correct answer: A

Rationale: The correct action for the PN to take is to instruct the UAP to walk on the client’s affected side. This is essential to provide the necessary support and prevent falls, especially when the client has weakness on one side due to a stroke. Walking on the affected side helps provide stability and assistance to the weaker side. Choice B is incorrect because it would be more appropriate for the PN to provide immediate guidance and correct the UAP's positioning rather than taking over the task completely. Choice C is incorrect because while assistive devices may be beneficial, the immediate concern is the UAP's positioning during ambulation, not providing the client with an assistive device. Choice D is incorrect as there is no indication to return the client to his room unless it is necessary for his safety or well-being.

3. Which nursing intervention is most appropriate for managing delirium in an elderly patient?

• A. Keeping the room brightly lit
• B. Administering sedatives as needed
• C. Encouraging family presence
• D. Restricting fluids

Correct answer: C

Rationale: Encouraging family presence is the most appropriate intervention for managing delirium in elderly patients. This intervention provides orientation, reassurance, and comfort, which can help reduce confusion and anxiety, thus aiding in managing delirium. Keeping the room brightly lit (Choice A) may worsen delirium as it can disrupt the patient's sleep-wake cycle. Administering sedatives (Choice B) should be avoided unless absolutely necessary due to the risk of worsening delirium. Restricting fluids (Choice D) is not a recommended intervention for managing delirium, as hydration is important for overall patient well-being.

4. What is the first action a healthcare professional should take when a patient’s nasogastric (NG) tube becomes clogged?

• A. Flush the tube with water
• B. Reposition the patient
• C. Attempt to aspirate the clog with a syringe
• D. Administer a medication to dissolve the clog

Correct answer: C

Rationale: When a patient's nasogastric (NG) tube becomes clogged, the first action to take is to attempt to aspirate the clog with a syringe. This is a standard and initial step to clear the blockage in the tube. Flushing the tube with water (Choice A) may not address the specific clog; repositioning the patient (Choice B) is not directly related to clearing the tube. Administering a medication to dissolve the clog (Choice D) should only be considered after simpler methods like aspiration have been attempted.

5. What is the primary reason for applying sequential compression devices (SCDs) to a patient’s legs postoperatively?

• A. To prevent deep vein thrombosis (DVT)
• B. To promote wound healing
• C. To reduce postoperative pain
• D. To maintain body temperature

Correct answer: A

Rationale: The correct answer is A: To prevent deep vein thrombosis (DVT). Sequential compression devices (SCDs) are used postoperatively to prevent DVT by promoting blood circulation in the legs. This helps reduce the risk of blood clots forming in the deep veins of the legs. Choice B, to promote wound healing, is incorrect as SCDs are primarily used for circulatory purposes rather than wound healing. Choice C, to reduce postoperative pain, is incorrect as the primary purpose of SCDs is not pain management but rather prevention of DVT. Choice D, to maintain body temperature, is incorrect as SCDs are not designed for regulating body temperature but for preventing circulatory issues.
