Communication within neurons is ______, communication between neurons is ________.
- A. excitatory, inhibitory
- B. inhibitory, excitatory
- C. chemical, electrical
- D. electrical, chemical
Correct Answer: D
Rationale: Communication within neurons is electrical, involving the propagation of action potentials along the axon. Communication between neurons, however, is chemical, relying on the release of neurotransmitters at the synapse. This combination of electrical and chemical signaling allows for rapid and precise communication within the nervous system, enabling complex behaviors and cognitive processes.
A patient has blindness related to a functional neurological (conversion) disorder. To help the patient eat, the nurse should:
- A. establish a buddy system with other patients who can feed the patient at each meal.
- B. expect the patient to feed himself or herself after explaining the arrangement of the food on the tray.
- C. direct the patient to locate items on the tray independently and feed himself or herself unassisted.
- D. address the needs of other patients in the dining room, and then feed this patient.
Correct Answer: B
Rationale: Correct Answer: B
Rationale:
1. Expecting the patient to feed himself/herself after explaining the arrangement of the food on the tray promotes independence and autonomy.
2. It respects the patient's capabilities and encourages self-reliance, which is important for rehabilitation in functional neurological disorders.
3. Providing clear instructions can help the patient navigate the task despite the blindness, fostering a sense of accomplishment.
4. This approach aligns with patient-centered care principles, prioritizing the patient's dignity and self-care abilities.
Summary of other choices:
A. Establishing a buddy system may not address the patient's need for independence and could potentially undermine their self-esteem.
C. Directing the patient to locate items independently may not be practical or safe given the blindness, and it may lead to frustration.
D. Neglecting the patient's needs in favor of others is not in line with providing individualized care and could compromise patient outcomes.
Which of the following pathways is not concerned with posture and movement?
- A. Spinocerebellar
- B. Vestibulospinal
- C. Tractus solitarius
- D. ?
Correct Answer: C
Rationale: The tractus solitarius is involved in taste and visceral sensation, not posture and movement. The spinocerebellar and vestibulospinal tracts are involved in motor coordination and balance.
The Schwann cells form a myelin sheath around the:
- A. dendrites
- B. cell body
- C. nucleus
- D. axon
Correct Answer: D
Rationale: Schwann cells are responsible for forming the myelin sheath around axons in the peripheral nervous system (PNS). Dendrites, cell bodies, nuclei, and nodes of Ranvier are not directly myelinated by Schwann cells. Therefore, D is the correct answer.
A patient exhibits sudden, severe headache and neck stiffness. What should the nurse do first?
- A. Perform a neurologic assessment and evaluate for signs of meningeal irritation.
- B. Measure the patient's blood pressure.
- C. Check the patient's blood glucose levels.
- D. Inspect the patient's throat.
Correct Answer: A
Rationale: Sudden, severe headache and neck stiffness may indicate meningitis. A neurologic assessment and evaluation for meningeal irritation are critical. Blood pressure, glucose levels, and throat inspection are secondary.
