Many newborns experience systemic acid/base abnormalities. In the case of chronic bouts of vomiting due to food poisoning, what type of acid/base disturbance is this individual likely to experience? Toxins released by Clostridium botulinum cause inhibitory activity of which neurotransmitter, resulting in respiratory arrest because they inhibit the binding and subsequent release of acetylcholine at the neuromuscular junction? DiGeorge syndrome is a disorder characterized by a lack of functional T-cells due to improper thymus development caused by a genetic mutation in the TBX1 gene. What specific type of immune disorder is this? The autoclave uses heat to irreversibly damage (denature) the basic structure of which important biological macromolecule? A patient has a prominent "bulls-eye" rash and states that she was recently hiking. What is the causative agent for this illness? The hepatitis viruses (primarily HCV and HBV) are strong risk factors for the development of which type of cancer? What is the major causative agent for both complicated and uncomplicated urinary tract infections in humans? A hospitalized patient with cystic fibrosis has developed blue-green pigmentation and ventilator-associated pneumonia. What agent has caused this infection? The sputum is thick and expectorated. Which of the following is the most common sexually transmitted infection (STI/STD) in the U.S.? Bacteria of the genus Lactobacillus most commonly colonize which human anatomical site? Which virus causes infectious mononucleosis in an otherwise healthy person but can cause Burkitt's lymphoma in an immunocompromised individual?

- A child of unclear toxic exposure history, but the following symptoms highly suggest the possibility of poisoning, EXCEPT ( )A. Acute onset of illness, B. Altered consciousness, C. Sustained fever, D. Multiple organ system dysfunctions, E. Puzzling clinical presentation. - A 7-year-old girl has had 5 days of fever, conjunctivitis, erythema of the oropharynx, and a generalized maculopapular rash. Her lips, lymph nodes, and extremities appear normal. Which of the following laboratory tests would NOT be used to establish a diagnosis? ( )A. Complete blood cell count (CBC), B. Urinalysis (UA), C. C-reactive protein (CRP), D. Erythrocyte sedimentation rate (ESR), E. Antinuclear antibody (ANA). - A 3-day-old infant, born at 32 weeks' gestation and weighing 1700 g (3 lb, 12 oz), has three episodes of apnea, each lasting 20 to 25 seconds and occurring after a feeding. During these episodes, the heart rate drops from 140 to 100 beats per minute, and the child remains motionless; between episodes, however, the child displays normal activity. Blood sugar is 50 mg/dL and serum calcium is normal. Which of the following is most likely true regarding the child's apneic periods? ( )A. They are due to an immature respiratory center, B. They are a part of periodic breathing, C. They are secondary to hypoglycemia, D. They are manifestations of seizures, E. They are evidence of underlying pulmonary disease. - A 2-year-old boy is being followed for congenital cytomegalovirus (CMV) infection. He is deaf and developmentally delayed. The child's mother informs you that she has just become pregnant and is concerned that the new baby will be infected and may develop serious consequences. Which of the following is true? ( )A. The mother has antibodies to CMV that are passed to the fetus, B. The mother's infection cannot become reactivated, C. The likelihood that the new baby will become clinically ill is approximately 80%, D. Termination of pregnancy is advised, E. The new infant should be isolated from the older child.

A 25-year-old female walks into a medical clinic in Boise complaining of an erythematous maculopapular rash, malaise, and fever of two days' duration. She also reports a headache, sore throat, and mild cough, but denies any gastrointestinal symptoms. Upon examination, she has a temperature of 38.5 C, blood pressure of 100/62 mm Hg, pulse rate of 110 beats per minute, and respiratory rate of 38 breaths per minute. She also reports malaise, swollen lymph nodes, and recent patchy hair loss. The doctor checks her buccal mucosa for Koplik's spots and asks about a recent history of tick bites. He also inquires about her MMR vaccination status and whether she might be pregnant. A throat culture is ordered and blood is drawn for serological testing. What bacterial or viral diseases might cause this type of rash and fever? (Give your differential diagnosis of about 5 diseases that this case study might be based upon) What is the doctor ruling out by looking for buccal mucosa lesions? Serology ordered includes RPR and Weil-Felix. What diseases will these tests diagnose? The throat culture reported negative for beta-hemolytic Group A Strep. The disease diagnosed serologically by a positive RPR and confirmed with an MHA-TP. What disease and stage of the disease is this? What risks does this pose to the fetus? Describe the usual symptoms seen at other stages of this disease and what the outcome might be without treatment.
