Question 1 of 5
A patient receives spinal anesthesia with lidocaine (Xylocaine) and epinephrine (Adrenalin). You explain that epinephrine is used with lidocaine for which of the following reasons?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
What does the experiment in which a frog's eye is rotated tell us about the spatial relationships between the retina and the tectum?
Correct Answer: B
Rationale: The frog eye rotation experiment demonstrates that retinal axons have an intrinsic map of their position. Nasal (anterior) neurons project to the posterior tectum, and temporal (posterior) neurons project to the anterior tectum. This shows that spatial information is encoded within the retina and guides axon targeting.
Question 3 of 5
Which of the following would lead the nurse to suspect that a child with meningitis has developed disseminated intravascular coagulation?
Correct Answer: A
Rationale: A hemorrhagic skin rash is a hallmark sign of disseminated intravascular coagulation (DIC), a severe complication of meningitis. DIC occurs due to widespread activation of the clotting cascade, leading to microthrombi and subsequent bleeding. This condition requires urgent medical intervention to prevent organ failure and death.
Question 4 of 5
Gray matter differs from white matter because gray matter _________ and white matter ______.
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The nurse is preparing material about the neurological system as part of a major presentation. What should the nurse include that explains the purpose of white matter?
Correct Answer: A
Rationale: White matter consists of myelinated nerve tracts that carry sensory or motor impulses within the central nervous system. It does not contain white blood cells, protect spinal nerves, or regulate movement directly. Understanding the function of white matter is crucial for explaining how information is transmitted in the nervous system.
