The nurse is caring for a patient who has had a stroke (brain attack). The patient is unable to understand what the nurse is saying and appears frustrated. What term should the nurse use to document this finding?

Correct Answer: C

Rationale: Receptive aphasia is the inability to understand spoken or written language, often resulting from damage to Wernicke's area in the brain. Dysphagia is difficulty swallowing, confusion is disorientation, and expressive aphasia is difficulty communicating verbally. Accurate documentation is essential for planning patient care.

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.

Correct Answer: D

Rationale: The correct answer is D: White blood cells (WBC) in cerebrospinal fluid (CSF). In meningitis, an infection of the meninges, the CSF will show an elevated WBC count indicating an inflammatory response. This finding is crucial for confirming the diagnosis as it directly reflects the presence of infection in the central nervous system. A: While a Glasgow Coma Scale score <15 may indicate altered mental status, it is not specific to meningitis. B: Pseudomonas aeruginosa on blood culture suggests a bacterial infection but does not confirm meningitis specifically. C: A normal MRI may not show definitive signs of meningitis, as the diagnosis is primarily made through CSF analysis.
