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. A child with glomerulonephritis is admitted in the acute edematous phase. Based on this diagnosis, which nursing intervention should the nurse plan to include in the child's plan of care?

• A. Recommend parents bring favorite snacks
• B. Encourage ambulation daily to the playroom
• C. Measure blood pressure every 4 to 6 hours
• D. Offer a selection of fresh fruit for each meal

Correct answer: C

Rationale: The correct answer is to measure blood pressure every 4 to 6 hours. Monitoring blood pressure frequently is crucial in managing glomerulonephritis, as hypertension is a common complication during the acute edematous phase. Choice A is incorrect as it does not address the specific needs of a child with glomerulonephritis. Choice B is incorrect as excessive activity may not be suitable during the acute phase, as rest and monitoring are more important. Choice D is incorrect as the focus should be on monitoring vital signs rather than meal options.

3. Which type of isolation is required for a patient with measles?

• A. Contact isolation
• B. Airborne isolation
• C. Droplet isolation
• D. Reverse isolation

Correct answer: B

Rationale: The correct answer is B: Airborne isolation. Measles is highly contagious and can be transmitted through airborne particles, so airborne isolation is necessary to prevent its spread. Choice A, Contact isolation, is incorrect because measles is not primarily transmitted through direct contact. Choice C, Droplet isolation, is also incorrect as measles is not transmitted through large droplets but through smaller airborne particles. Choice D, Reverse isolation, is used to protect a patient from outside infections, not to prevent the spread of a contagious disease like measles.

4. A post-operative client is recovering from a total knee replacement and is prescribed patient-controlled analgesia (PCA). What is the primary advantage of PCA for managing post-operative pain?

• A. It allows for consistent pain control without overmedication.
• B. It eliminates the need for oral pain medication.
• C. It reduces the risk of opioid addiction.
• D. It requires less monitoring by nursing staff.

Correct answer: A

Rationale: The primary advantage of PCA for managing post-operative pain is that it allows the client to control the administration of pain medication, leading to consistent pain control without overmedication. Choice B is incorrect as PCA does not eliminate the need for oral pain medication; it supplements it. Choice C is incorrect because while PCA can help reduce opioid consumption, it does not directly reduce the risk of opioid addiction. Choice D is incorrect as PCA actually requires close monitoring by nursing staff to ensure proper use and prevent complications.

5. An older postoperative client has the nursing diagnosis 'impaired mobility related to fear of falling.' Which desired outcome best directs the PN's actions for the client?

• A. The client will ambulate with assistance every 4 hours
• B. The physical therapist will instruct the client in the use of a walker
• C. The client will use self-affirmation statements to decrease fear
• D. The PN will place a gait belt on the client prior to ambulation

Correct answer: C

Rationale: The correct answer is C. Using self-affirmation statements helps the client reduce fear and regain confidence in mobility, which is essential for improving impaired mobility. Choice A focuses more on the frequency of ambulation rather than addressing the fear of falling. Choice B involves the physical therapist and the use of a walker, which may not directly address the client's fear. Choice D is a safety measure but does not specifically target the client's fear of falling.
