A 24-year-old male university student is admitted to the general surgery service following a high-impact motor vehicle collision. Initial assessment in the emergency department revealed signs of hypovolemic shock, including a blood pressure of 97/58 mmHg and a heart rate of 112/min, with an oxygen saturation of 93% on room air. He had been rendered unconscious initially but became responsive after aggressive fluid resuscitation. He reports a history of a viral illness about 10 days prior, characterized by malaise, sore throat, and generalized fatigue, for which he was prescribed amoxicillin, resulting in a diffuse maculopapular rash. A focused assessment with sonography for trauma (FAST) confirmed a significant amount of free fluid in Morrison's pouch and extending into the pelvis. Physical examination shows a distended, tender abdomen, particularly in the left upper quadrant. Despite initial fluid boluses, his hemodynamic status remains tenuous, requiring ongoing resuscitation. Considering his presentation, what is the most appropriate definitive management strategy, and what is a critical long-term complication to anticipate following such an intervention?

A 19-year-old woman arrives at a university health center complaining of profound fatigue, persistent sore throat, and difficulty swallowing that started approximately 10 days ago. She reports a low-grade fever, general body aches, and decreased appetite. Her medical history is unremarkable, and she is not on any regular medications. She is a first-year student living in a dormitory, often shares drinks with friends, and has been feeling run down since attending several campus social events. On examination, her oral temperature is 38.10C, blood pressure is 110/70 mmHg, heart rate is 88 beats/min, respiratory rate is 16 breaths/min, and oxygen saturation is 99% on room air. Inspection of the oropharynx reveals diffuse erythema with grayish-white exudates covering both tonsils, similar to the appearance shown in Figure A. Palpation uncovers diffuse, tender cervical lymphadenopathy, most prominent in the posterior triangles, and a palpable splenic tip approximately 2 cm below the left costal margin during inspiration. Given this clinical presentation, what is the most appropriate initial management strategy, and what crucial long-term advice should be given to prevent complications?

A 16-year-old female presents to an outpatient clinic with a chief complaint of persistent fatigue, sore throat, and generalized malaise for the past week. Her initial evaluation included a positive Monospot test. Two weeks later, she returns to the emergency department after experiencing sudden, sharp left upper quadrant abdominal pain and lightheadedness following a seemingly minor stumble during a casual walk. On examination, she is pale and tachycardic with a pulse of 110/min and blood pressure of 95/60 mmHg. Abdominal examination reveals marked tenderness and guarding in the left upper quadrant, with rebound tenderness. Her temperature is 37.5°C, respirations 18/min, and oxygen saturation 98% on room air. Imaging confirms a splenic injury requiring intervention. Several months after her recovery, during a routine follow-up, a peripheral smear is performed, revealing basophilic inclusions in some erythrocytes (as seen in Figure A).

A 22-year-old university student presents to an outpatient clinic with a chief complaint of profound fatigue and a persistent sore throat for the past week. She reports difficulty concentrating in classes due to overwhelming tiredness, occasional fevers, and generalized body aches. On physical examination, her temperature is 38.8 C (101.8 F), pulse 98/min, blood pressure 118/72 mmHg, respirations 18/min. Examination reveals bilateral tonsillar enlargement with yellowish exudates, and palpable, mildly tender lymphadenopathy in the anterior and posterior cervical regions. Abdominal palpation uncovers mild splenomegaly, extending approximately 2 cm below the left costal margin. Given these clinical findings and the patient's presentation, what is the most likely diagnosis and the crucial initial management strategy to consider?

A 21-year-old female university student presents to an urgent care center complaining of severe fatigue, generalized body aches, and a persistent sore throat for the past week. She initially visited her general practitioner three days ago, who suspected a bacterial infection and prescribed amoxicillin. Shortly after starting the antibiotic, she developed a diffuse, erythematous maculopapular rash, which she describes as non-itchy and starting on her trunk before spreading to her limbs. Her roommate recently recovered from a similar viral illness. She is a member of the university's intramural soccer team but has missed recent practices due to her symptoms. Her medical history is significant for well-controlled asthma and seasonal allergies, for which she takes an inhaled corticosteroid and cetirizine as needed. She denies any known drug allergies. On examination, her temperature is 38.5°C, blood pressure 118/72 mmHg, heart rate 102/min, and respiratory rate 18/min. She has prominent tonsillar exudates, significant posterior and anterior cervical lymphadenopathy, and mild hepatosplenomegaly noted on abdominal palpation. The maculopapular rash is diffuse over her trunk and extremities. Considering her clinical presentation, what is the most likely diagnosis and the paramount immediate management consideration?

An 18-year-old female college student presents to the campus health service reporting 3 days of increasing fatigue, a persistent sore throat, and a subjective fever. She mentions difficulty concentrating in her classes due to the overwhelming tiredness. Her temperature is 38.2°C, blood pressure is 112/76 mmHg, pulse is 98/min, respirations are 18/min, and oxygen saturation is 99% on room air. Physical examination reveals bilateral posterior cervical lymphadenopathy, a mildly enlarged spleen palpable 2 cm below the left costal margin, and tonsillar exudates. A rapid streptococcal antigen test performed on arrival was negative. Considering the presenting symptoms and physical findings, what is the most likely diagnosis and the immediate primary management?
