Which оf these stаtements regаrding fоlic аcid deficiency and perniciоus anemia is true?
A 48-yeаr-оld wоmаn cаlls 911 and is brоught to the emergency room complaining of a sudden onset of dyspnea. She reports she was standing in the kitchen making dinner, when she suddenly felt as if she could not get enough air, her heart started racing, she became lightheaded and felt as if she would faint. She denied chest pain or cough. Her medical history is significant for gallstones, for which she underwent a cholecystectomy 2 weeks ago. The procedure was complicated by a wound infection, requiring her to stay in the hospital for 8 days. She takes no medications regularly, only acetaminophen as needed for pain at her abdominal incision site. On examination, she is tachypneic with a respiratory rate of 28 breaths per minute, oxygen saturation is 84% on room air, heart rate 124, and blood pressure 118/89 mm Hg. She appears uncomfortable, diaphoretic, and frightened. Her oral mucosa is slightly cyanotic, her jugular venous pressure is elevated, and her chest is clear to auscultation. Her apical heart rhythm is tachycardic but regular rhythm with a loud S2 in the pulmonic area, no gallop or murmur. Her abdominal examination is benign. Incision site is normal without signs of infection. Her right leg is moderately swollen from mid-thigh to her feet, and her thigh and calf are mildly tender to palpation. Laboratory studies including cardiac enzymes are normal, her electrocardiogram (ECG) reveals sinus tachycardia, and her chest X-ray is interpreted as normal. What information in the history gives you a clue to her diagnosis?
A 65-yeаr-оld Africаn-Americаn wоman presented tо the emergency room complaining of worsening shortness of breath and palpitations for about 1 week. She reports feeling "dizzy" on and off for the past year; the dizziness is associated with weakness that has been worsening for the past month. She has been feeling "too tired" to even walk to her backyard and water her flower bed that she used to do "all the time." She has been so dyspneic walking up the stairs at her home that she moved downstairs to the guest room about a week ago. Review of systems is significant for knee pain, for which she frequently takes aspirin or ibuprofen; otherwise, the review of systems is negative. She has no significant medical history and has not been to a doctor in several years. She had a normal well-woman examination and screening colonoscopy about 5 years ago. She occasionally has an alcoholic drink and denies tobacco or drug use. She is married and is a retired shopkeeper. On examination, her blood pressure is 150/85 mm Hg; her pulse is 98 beats/min; her respiratory rate is 20 breaths/min; her temperature is 98.7°F (37.1°C); and her oxygen saturation is 99% on room air. Significant findings on examination include conjunctival pallor, mild tenderness with deep palpation in the epigastric and left upper quadrant (LUQ) region of the abdomen with normal bowel sounds, and no organomegaly but a positive stool hemoccult test. The remainder of the examination, including respiratory, cardiovascular, and nervous systems, was normal. What would you do next??
