Neurological Disorders in Medical Surgical Nursing Questions
Question 1 of 5
Nurses in change-of-shift report are discussing the care of a patient with a stroke who has progressively increasing weakness and decreasing level of consciousness. Which patient problem do they determine has the highest priority for the patient?
Correct Answer: A
Rationale: Decreasing consciousness increases aspiration risk, a life-threatening issue. Others are chronic concerns. [Level: Analysis]
Question 2 of 5
The rapid reversal of electrical potential along the membrane of a neuron is called an:
Correct Answer: A
Rationale: An action potential is the rapid depolarization/repolarization during signaling. Resting potential is baseline. [Level: Knowledge]
Question 3 of 5
The myelin sheath produced by Schwann cells serves to:
Correct Answer: D
Rationale: Myelin speeds conduction via insulation and saltatory conduction. It doesn’t transmit directly. [Level: Knowledge]
Question 4 of 5
The undershoot or after-hyperpolarization phase of an action potential is mainly due to:
Correct Answer: B
Rationale: Excess K+ efflux causes temporary hyperpolarization below resting potential. [Level: Knowledge]
Question 5 of 5
In which type of synapse is communication between neurons mediated by neurotransmitters?
Correct Answer: A
Rationale: Chemical synapses use neurotransmitters across a cleft, unlike electrical synapses. [Level: Knowledge]
