A clinical diagnosis of meningitis was suspected. Yellow-gray colonies after 24-hour incubation had been observed on blood agar.

The doctor reviews the following test results: Plasma creatinine = 2.4 mg/dL Urine creatinine = 65 mg/dL Urine volume (24 hrs) = 1400 mL What is the estimated glomerular filtration rate for this patient? - correct answer (Urine creatinine / plasma creatinine) x (volume / minute) = glomerular filtration rate (mL/min) *in order to solve this problem, the 24 hour urine must be converted into minutes. 1440 minutes should be used as the denominator in the volume component. So...for this patient, the calculation would be: ( 65 mg/dL / 2.4 mg/dL ) X ( 1400 mL / 1440 min ) = (27.083) X (0.972 mL/min) = = 26.32 mL/min All of the listed disorders are organ non-specific autoimmune diseases EXCEPT: - correct answer Hashimoto's disease What is the main function of thrombocytes? - correct answer To assist in the coagulation process A lipid panel consists of which of the following tests? - correct answer Cholesterol, Lipoprotein, HDL, Triglycerides Which Aspergillus species show biseriate with phialides covering the entire surface of a spherical vesicle with black conidia as microscopic morphological features? - correct answer Aspergillus niger An increased number of the cells seen in the image, upon microscopic examination of urine is termed: - correct answer Hematuria The VDRL and RPR are used to provide presumptive identification of which infection? - correct answer Syphilis What is the explanation for a discrepancy in the following front type and back type in a newborn?
