When a patient is hospitalized with a possible stroke, the AGACNP recognizes that the stroke most likely resulted from a subarachnoid hemorrhage when the patients family reports that the patient

Correct Answer: A

Rationale: The key clinical manifestation indicating a possible subarachnoid hemorrhage in this scenario is that the patient had been complaining of a headache before losing consciousness. Subarachnoid hemorrhage is a type of stroke that results from bleeding into the space between the arachnoid membrane and the pia mater surrounding the brain. Severe headache, often described as the worst headache of one's life, is a classic symptom of subarachnoid hemorrhage. The sudden onset of a severe headache before loss of consciousness raises the suspicion for this type of stroke. Other symptoms such as mental confusion and weakness may also be present, but the headache is a crucial indicator in this case.

Correct Answer: A

Rationale: Achalasia is a motility disorder characterized by the inability of the lower esophageal sphincter to relax, resulting in difficulty swallowing and impaired movement of food from the esophagus into the stomach. Patients with achalasia have an increased risk of developing squamous cell carcinoma of the esophagus. This risk is due to chronic inflammation, stasis of food in the esophagus, and increased exposure of esophageal mucosa to irritants, all of which can contribute to the development of cancer over time. Gastroesophageal reflux disease (Choice B) is less likely to be associated with achalasia because the impaired esophageal motility in achalasia results in decreased, rather than increased, reflux of stomach contents into the esophagus. Esophageal atrophy (Choice C) and malabsorption syndromes (Choice D) are not directly related to achalasia.
