Rationale: The death of Lory is the precipitating factor for Ella's feeling of wanting to die. Losing someone close to us can lead to feelings of profound sadness, grief, and hopelessness, which may trigger thoughts of wanting to die.

In Ella's case, the death of Lory has likely caused a significant emotional upheaval, contributing to her desire to end her own life. It is essential to address these feelings of loss and provide support and intervention to help Ella cope with her grief and prevent any self-harm.

Correct Answer: C

Rationale: Cryptosporidium parvum is a parasite commonly found in contaminated water sources such as streams or lakes. It causes an infection called cryptosporidiosis, which often presents with symptoms like watery diarrhea, abdominal cramps, and nausea. The oocysts of Cryptosporidium parvum can be identified in stool samples, making it the likely culprit in this scenario. Giardia lamblia, another common waterborne parasite, can also cause similar symptoms but is characterized by trophozoites rather than oocysts in stool samples. Entamoeba histolytica is associated with amoebic dysentery and does not typically present with watery diarrhea. Cyclospora cayetanensis is another parasite causing gastrointestinal symptoms but is not as commonly associated with contaminated water sources as Cryptosporidium parvum.

Correct Answer: A

Rationale: The patient is presenting with sudden-onset weakness and sensory loss on one side of the body along with difficulty speaking and understanding speech, which are classic symptoms of a stroke. The involvement of the right middle cerebral artery territory on imaging suggests an acute infarction, confirming an ischemic stroke. Ischemic stroke occurs due to a blockage or obstruction within a blood vessel supplying blood to the brain, leading to a lack of oxygen and nutrients reaching brain tissue. This results in neurological deficits corresponding to the affected area of the brain. In contrast, a transient ischemic attack (TIA) would present with similar symptoms but resolve within 24 hours without evidence of acute infarction on imaging. Intracerebral hemorrhage and subarachnoid hemorrhage involve bleeding into the brain tissue or the space surrounding the brain, respectively, resulting in different clinical presentations.

Correct Answer: D

Rationale: The given clinical presentation of chest pain that worsens with swallowing and is relieved by leaning forward along with diffuse ST-segment elevation on an ECG is highly suggestive of pericarditis. Pericarditis is the inflammation of the pericardium, the thin sac surrounding the heart. The symptoms of pericarditis can mimic those of myocardial infarction (heart attack) but can also be differentiated by certain characteristics such as the described positional chest pain, which is worsened by swallowing and relieved by leaning forward.
