The nurse is caring for a patient admitted to the emergency room after a motor vehicle crash. Which assessment is most important for the nurse to complete?

Correct Answer: C

Rationale: The Glasgow Coma Scale (GCS) is the most important assessment for evaluating the level of consciousness in a patient with a head injury. The Babinski and Romberg tests assess motor function and balance, while the visual analogue scale measures pain. The GCS provides critical information about the patient's neurological status.

Correct Answer: D

Rationale: Neurons are classified into sensory neurons, which transmit information from sensory receptors to the central nervous system, and motor neurons, which carry signals from the central nervous system to muscles and glands. Skeletal refers to muscle tissue, not neuron types. Understanding these types helps explain how the nervous system processes and responds to information.

Correct Answer: B

Rationale: The correct answer is B: amygdala. The amygdala is responsible for generating stress responses through its connections with the hypothalamus. It plays a crucial role in processing emotions, including fear and anxiety. The hippocampus (A) is involved in memory formation, not stress responses. The mammillary bodies (C) are part of the hypothalamus but are not directly responsible for generating stress responses. The prefrontal cortex (D) is involved in decision-making and impulse control, not stress responses. Thus, the amygdala is the correct choice for its specific role in triggering stress responses via the hypothalamus.

Correct Answer: B

Rationale: The correct answer is B: Streptococcus agalactiae. This bacterium is the most common cause of neonatal meningitis due to its ability to colonize the maternal genital tract and be transmitted to the newborn during delivery. It is a leading cause of early-onset neonatal sepsis and meningitis. Haemophilus influenzae b, Neisseria meningitidis, and Streptococcus pneumoniae are more commonly associated with meningitis in older children and adults, rather than in neonates. Therefore, choice B is the most appropriate answer based on the specific context of neonatal meningitis.

Correct Answer: A

Rationale: The correct answer is A: neurocysticercosis. Neurocysticercosis is the most common cause of adult onset epilepsy worldwide. It is caused by the larval stage of the tapeworm Taenia solium. The larvae can infect the brain and lead to seizures. Neurotoxoplasmosis (B) is more commonly associated with HIV patients. Primary amoebic meningoencephalitis (C) is caused by the amoeba Naegleria fowleri and is rare. African trypanosomiasis (D) does not typically cause epilepsy. Therefore, neurocysticercosis is the most important cause of adult onset epilepsy due to its global prevalence and direct impact on the brain leading to seizures.
