Question 1

1 / 1 point

A patient with a diagnosis of depression has been prescribed a medication that ultimately increases the levels of the neurotransmitter serotonin between neurons. Which of the following processes will accompany the actions of the neurotransmitter in her chemical synapses?

Question options:

More serotonin molecules will cross the synaptic cleft and bond with postsynaptic receptors.

The neurotransmitter will cross gap junctions more readily.

Communication between a neuron and the single neuron it is connected with will be facilitated.

Two-way communication between neurons is permitted, in contrast to the one-way communication in electrical synapses.

Which of the following diagnoses best captures this pathophysiology?

Question options:

The unique clinical presentation of a three-month-old infant in the emergency department leads the care team to suspect botulism. Which of the following assessment questions posed to the parents is likely to be most useful in the differential diagnosis?

Question options:

“Is there any mold in your home that you know of?”

“Has your baby ever been directly exposed to any chemical cleaning products?”

“Is there any family history of neuromuscular diseases?”

Question 5

Which of the following diagnostic findings is likely to result in the most serious brain insult?

Question options:

High intracellular concentration of glutamate

Increased ICP accompanied by hyperventilation

Moderate increase in brain tissue volume secondary to a brain tumor

Mean arterial blood pressure (MABP) that equals intracranial pressure (ICP)

Question 6

A patient on an acute medicine unit of a hospital, with a diagnosis of small bowel obstruction, is complaining of intense, diffuse pain in her abdomen. Which of the following physiologic phenomena is most likely contributing to her complaint?

Question options:

The patient’s C fibers are conducting pain in the absence of damaged Ad fibers.

The patient is experiencing neuropathic pain.

First-order neurons are inappropriately signaling pain to the dorsal root ganglion.

Nociceptive afferents are conducting the sensation of pain along the cranial and spinal nerve pathways of the ANS.

Which of the nurse’s following questions is least likely to yield data that will allow for a confirmation or ruling out of migraines as the cause of his problem?

Question options:

“Is your son generally pain free during the intervals between headaches?”

Question options:

A bilateral, multisynaptic, slow-conducting tract

The opposite anterolateral pathway that travels to the reticular activating system

A slow-conducting pathway that projects into the intralaminar nuclei of the thalamus
