A neonate born at 33 weeks is transferred to the NICU after a complicated pregnancy and C-section. A week after being admitted, he developed a fever and became lethargic and minimally responsive to stimuli. A lumbar puncture is performed that reveals the following: Appearance Cloudy Protein 64 mg/dL Glucose 22 mg/dL Pressure 330 mm H20 Cells 295 cells/mm³ (> 90% PMN) A specimen is sent to microbiology and reveals gram-negative rods. Which of the following is the next appropriate step in management?
AMRI scan of the head
BStart the patient on IV ceftriaxone
CProvide supportive measures only
DStart the patient on IV cefotaxime
EStart the patient on oral rifampin
A 27-year-old woman, gravida 2, para 1, at 37 weeks' gestation is admitted to the hospital in active labor. She has received routine prenatal care, but she has not been tested for group B streptococcal (GBS) colonization. Pregnancy and delivery of her first child were complicated by an infection with GBS that resulted in sepsis in the newborn. Current medications include folic acid and a multivitamin. Vital signs are within normal limits. The abdomen is nontender and contractions are felt every 4 minutes. There is clear amniotic fluid pooling in the vagina. The fetus is in a cephalic presentation. The fetal heart rate is 140/min. Which of the following is the most appropriate next step in management?
AObtain vaginal-rectal swab for nucleic acid amplification testing
BObtain vaginal-rectal swab for GBS culture
CAdminister intrapartum intravenous penicillin
DReassurance
EObtain vaginal-rectal swab for GBS culture and nucleic acid amplification testing
A 70-year-old woman is on hospital day 2 in the medical intensive care unit. She was admitted from the emergency department for a 2-day history of shortness of breath and fever. In the emergency department, her temperature is 39.4°C (103.0°F), the pulse is 120/min, the blood pressure is 94/54 mm Hg, the respiratory rate is 36/min, and oxygen saturation was 82% while on 4L of oxygen via a non-rebreather mask. Chest X-ray shows a right lower lobe consolidation. She was intubated, sedated, and started on broad-spectrum antibiotics for sepsis of pulmonary origin and intravenous norepinephrine for blood pressure support. Since then, her clinical condition has been stable, though her vasopressor and oxygen requirements have not improved. Today, her physician is called to the bedside because her nurse noted some slow bleeding from her intravenous line sites and around her urinary catheter. Which of the following most likely represents the results of coagulation studies for this patient?
AD-dimer: negative, fibrinogen level: low, platelet count: low
BD-dimer: elevated, fibrinogen level: normal, platelet count: normal
CD-dimer: elevated, fibrinogen level: low, platelet count: low
DD-dimer: negative, fibrinogen level: elevated, platelet count: elevated
ED-dimer: negative, fibrinogen level: normal, platelet count: normal
