Why should the nurse wake up a client, who is to undergo an EEG, at midnight?
- A. Because excess sleep may make the client lazy and nervous for the EEG.
- B. Because optimum sleep helps regulate the breathing patterns during the EEG.
- C. Because it helps the client to fall asleep naturally during the EEG.
- D. Because it reduces the chances of getting a headache when electrodes are fixed to the client's scalp.
Correct Answer: C
Rationale: Natural sleep cycles improve EEG results.
The 'synaptic cleft' of a neuromuscular junction is
- A. a groove in the muscle cell plasma membrane through which neurons grow
- B. that portion of the cell surface receptor molecule on the surface of a muscle cell, into which the ligand binds
- C. a depression at the end of an axon from which neurotransmitters are secreted
- D. the space between the plasma membrane of a neuron on the pre-synaptic side of the synapse, and the plasma membrane of the muscle cell on the post-synaptic side of the synapse
Correct Answer: D
Rationale: The synaptic cleft is the narrow space between the presynaptic neuron and the postsynaptic muscle cell. It is where neurotransmitters are released and diffuse to bind receptors on the muscle cell, initiating muscle contraction. This structure is essential for signal transmission at the neuromuscular junction.
Which nerve projects to the hypothalamus to indicate the level of light stimuli in the retina?
- A. glossopharyngeal
- B. oculomotor
- C. optic
- D. vagus
Correct Answer: C
Rationale: The correct answer is C: optic nerve. The optic nerve carries visual information from the retina to the brain, including the hypothalamus. Light stimuli levels are detected by the retina and transmitted via the optic nerve to the hypothalamus for regulating various physiological processes.
A: glossopharyngeal - This nerve is responsible for taste and some motor functions in the throat, not related to light stimuli detection in the retina.
B: oculomotor - This nerve controls eye movements, not directly involved in transmitting light stimuli levels to the hypothalamus.
D: vagus - This nerve is responsible for parasympathetic functions in the body, not related to processing light stimuli information in the retina.
During the diagnosis and long-term management of a seizure disorder, what should the nurse recognize as one of the major needs of the patient?
- A. Managing the complicated drug regimen of seizure control
- B. Coping with the effects of negative social attitudes toward epilepsy
- C. Adjusting to the very restricted lifestyle required by a diagnosis of epilepsy
- D. Learning to minimize the effect of the condition in order to obtain employment
Correct Answer: B
Rationale: Social stigma can significantly impact patients with epilepsy
The nurse is caring for an individual with a head injury and notes unequal pupils. Which term should the nurse use to document this finding?
- A. Aphasia
- B. Nystagmus
- C. Anisocoria
- D. Ophthalmoplegia
Correct Answer: C
Rationale: Anisocoria refers to unequal pupil size, which can indicate neurological dysfunction. Aphasia is a language disorder, nystagmus is involuntary eye movement, and ophthalmoplegia is the inability to move the eyes. Documenting anisocoria accurately is important for assessing potential brain injury.
