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. Which assessment finding would most likely indicate a complication of enteral tube feeding?

• A. Abdominal distension
• B. Weight gain
• C. Decreased bowel sounds
• D. Diarrhea

Correct answer: A

Rationale: Abdominal distension in a patient receiving enteral tube feeding may indicate a complication such as intolerance to feeding, delayed gastric emptying, or obstruction. Abdominal distension is a common sign of gastrointestinal issues related to enteral tube feeding. Weight gain is typically an expected outcome if the patient is receiving adequate nutrition. Decreased bowel sounds may indicate decreased motility but are not specific to enteral tube feeding complications. Diarrhea can occur due to various reasons, including infections, medications, or dietary changes, but it is not the most likely indication of a complication in enteral tube feeding.

3. What is the function of the epiglottis during swallowing?

• A. Prevents food from entering the trachea
• B. Aids in food propulsion
• C. Enhances taste sensation
• D. Lubricates the esophagus

Correct answer: A

Rationale: The epiglottis is a flap of tissue that closes over the trachea during swallowing to prevent food and liquids from entering the airway. Choice A is correct because the primary function of the epiglottis is to act as a lid over the trachea, ensuring that food goes down the esophagus and not into the windpipe. Choices B, C, and D are incorrect as they do not describe the specific role of the epiglottis during swallowing.

4. To accommodate a patient who is an Orthodox Jew, you would assure that her diet does not include which of the following?

• A. Any combination of meat and milk at the same meal
• B. Fish with scales
• C. Salmon
• D. Grape juice

Correct answer: A

Rationale: The correct answer is A. Orthodox Jewish dietary laws prohibit mixing meat and dairy in the same meal, so to accommodate an Orthodox Jew, you should ensure that their diet does not include any combination of meat and milk at the same meal. Choices B, C, and D are not prohibited in a kosher diet. Fish with scales, including salmon, are typically kosher, and grape juice is also permissible under kosher guidelines if certified. Therefore, options B, C, and D are acceptable in an Orthodox Jewish diet, while option A contradicts their dietary laws.

5. When caring for a patient with a chest tube, which nursing action is most important?

• A. Clamping the chest tube every 2 hours to prevent air leaks
• B. Keeping the drainage system below chest level
• C. Emptying the drainage system every hour to prevent backflow
• D. Removing the chest tube when drainage decreases significantly

Correct answer: B

Rationale: The most crucial nursing action when caring for a patient with a chest tube is to keep the drainage system below chest level (choice B). This position helps ensure proper drainage and prevents backflow of fluid or air into the pleural space, promoting optimal functioning of the chest tube. Clamping the chest tube every 2 hours (choice A) is incorrect as it can obstruct the drainage system and lead to complications. Emptying the drainage system every hour (choice C) is unnecessary unless there are specific clinical indications. Removing the chest tube when drainage decreases significantly (choice D) is also incorrect as the decision should be based on overall clinical assessment rather than drainage amount alone.
