Mid term weeks 1-4 Question 1 2 / 2 pts What is the most abundant class of plasma protein? Globulin Albumin Clotting factors Complement proteins Albumin (approximately 60% of total plasma prot... ein at a concentration of about 4 g/dl) is the most abundant plasma protein. IncorrectQuestion 2 0 / 2 pts Carcinoma in situ is characterized by which changes? Cells have broken through the local basement membrane. Cells have invaded immediate surrounding tissue. Cells remain localized in the glandular or squamous cells. Cellular and tissue alterations indicate dysplasia. Carcinoma in situ (CIS) refers to preinvasive epithelial malignant tumors of glandular or squamous cell origin. These early stage cancers are localized to the epithelium and have not broken through the local basement membrane or invaded the surrounding tissue. Dysplasia refers to changes in mature cell structure. Question 3 2 / 2 pts Which laboratory test is considered adequate for an accurate and reliable diagnosis of gonococcal urethritis in a symptomatic man? Ligase chain reaction (LCR) Gram-stain technique Polymerase chain reaction (PCR) DNA testing Microscopic evaluation of Gram-stained slides of clinical specimens is deemed positive for Neisseria gonorrhoeae if gram-negative diplococci with the typical “kidney bean” morphologic appearance are found inside polymorphonuclear leukocytes. Such a finding is considered adequate for the diagnosis of gonococcal urethritis in a symptomatic man. The other options are not relevant to the diagnosis of this condition. Question 4 2 / 2 pts The Papanicolaou (Pap) test is used to screen for which cancer? Ovarian Uterine Cervical Vaginal The Pap test, an examination of cervical epithelial scrapings, readily detects early oncogenic human papillomavirus (HPV)infection. The Pap test is not used for screening the other cancer sites listed. IncorrectQuestion 5 0 / 2 pts Causes of hyperkalemia include: Hyperparathyroidism and malnutrition Vomiting and diarrhea Renal failure and Addison disease Hyperaldosteronism and Cushing disease Hyperkalemia should be investigated when a history of renal disease, massive trauma, insulin deficiency, Addison disease, use of potassium salt substitutes, or metabolic acidosis exists. The other options are not known to be causes of hyperkalemia. Question 6 2 / 2 pts What is the major concern regarding the treatment of gonococci infections? Development of antibiotic resistance Changes in virulence Changes in pathogenicity Mutations into different strains Several types of drug-resistant strains have been identified; they are penicillinaseproducing Neisseria gonorrhoeae (PPNG), which is resistant to penicillin; tetracyclineresistant N. gonorrhoeae (TRNG), which is resistant to tetracycline; chromosomal control of mechanisms of resistance of N. gonorrhoeae (CMRNG), which is resistant to penicillin and tetracycline; and increasingly a fluoroquinolone-resistant N. gonorrhoeae (QRNG). The other options are not major concerns. Question 7 2 / 2 pts Hypersensitivity is best defined as a(an): Disturbance in the immunologic tolerance of self-antigens Immunologic reaction of one person to the tissue of another person Altered immunologic response to an antigen that results in disease Undetectable immune response in the presence of antigens Hypersensitivity is an altered immunologic response to an antigen that results in disease or damage to the host. The other options are not accurate definitions of hypersensitivity. Question 8 2 / 2 pts Which immunoglobulin (Ig) is present in childhood asthma? IgM IgG IgE IgA Included in the long list of asthma-associated genes are those that code for increased levels of immune and inflammatory mediators (e.g., interleukin [IL]–4, IgE, leukotrienes), nitric oxide, and transmembrane proteins in the endoplasmic reticulum. None of the other options are associated with childhood asthma. Question 9 2 / 2 pts Which criterion is used to confirm a diagnosis of [Show More]
