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. An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units in the morning. Which finding should the nurse document as evidence that the amount of insulin is inadequate?

• A. States that her feet are constantly cold and numb
• B. A wound on the ankle that starts to drain and becomes painful
• C. Consecutive evening serum glucose greater than 260 mg/dL
• D. Reports nausea in the morning but still able to eat breakfast

Correct answer: C

Rationale: The correct answer is C. Consistently high evening glucose levels indicate that the current insulin dosage is inadequate to maintain proper glucose control. Choice A is incorrect because cold and numb feet are more indicative of peripheral vascular disease rather than inadequate insulin dosage. Choice B describes a wound that may be related to poor circulation or neuropathy but not necessarily inadequate insulin dosage. Choice D suggests gastrointestinal issues that are not directly related to insulin dosage adequacy.

3. A nurse is assessing a day-old infant for jaundice. Which of the following is the best method for this?

• A. Applying pressure over a bony area such as the forehead and evaluating the skin color after the pressure is removed
• B. Assessing the color of the infant’s hands and feet
• C. Assessing the infant’s tongue
• D. Assessing the infant’s arms and legs

Correct answer: A

Rationale: The correct answer is A. Applying pressure over a bony area and evaluating the skin color after the pressure is removed is the most accurate method for assessing jaundice in a day-old infant. This technique helps in identifying any yellowing of the skin, which is a key indicator of jaundice. Choices B, C, and D are less effective methods for assessing jaundice in a newborn. Assessing the color of the hands and feet may not give a reliable indication of jaundice, while evaluating the tongue, arms, and legs are not as specific or accurate as applying pressure over a bony area.

4. An 8-year-old child is placed in 90-90 traction for a fractured femur. The nurse notices that the weights are touching the foot of the bed. What action should the nurse take?

• A. No bowel movement for two days
• B. Mother helps reposition the child
• C. Ensure weights are not touching the foot of the bed
• D. Child wiggles toes freely when tickled

Correct answer: C

Rationale: The nurse should ensure that the weights in traction are not touching the foot of the bed. This is crucial to maintain proper alignment and effectiveness of the traction. When the weights touch the bed, it can compromise the traction's function and delay healing. Choices A, B, and D are incorrect as they do not address the issue of ensuring that the weights are not touching the bed, which is essential for the traction to work effectively.

5. The nurse is assigned to administer medications in a long-term care facility. A disoriented resident has no identification band or picture. What is the best nursing action for the nurse to take prior to administering the medications to this resident?

• A. Ask a regular staff member to confirm the resident's identity
• B. Hold the medication until a family member can confirm identity
• C. Re-orient the resident to name, place, and situation
• D. Confirm the room and bed numbers with those on the medication record

Correct answer: A

Rationale: In a long-term care facility, when a disoriented resident lacks identification, it is crucial to confirm the resident's identity before administering medication to prevent errors. Asking a regular staff member who is familiar with the resident to confirm their identity is the best course of action. This ensures accuracy and safety in medication administration. Holding the medication until a family member can confirm the identity could delay necessary treatment. Re-orienting the resident is important for their well-being but does not address the immediate medication safety concern. Confirming room and bed numbers, though important for administration logistics, does not verify the resident's identity.
