Week 2 quiz
Question 1.
A 60-year-old woman is suspected of having non-Hodgkin lymphoma (NHL). Which of the following aspects of her condition would help to rule out Hodgkin lymphoma?
Her neoplasm originates in secondary lymphoid structures.
The lymph nodes involved are located in a large number of locations in the lymphatic system.
The presence of Reed-Sternberg cells has been confirmed.
The woman complains of recent debilitating fatigue.
Question 2.
Which of the following patients is most likely to benefit from transplantation of thymic tissue or major histocompatibility complex (MHC)-compatible bone marrow?
A 12-year-old girl with a history of epilepsy and low IgG levels secondary to phenytoin use
A 7-year-old boy whose blood work indicates decreased IgA and IgG with increased IgM
A 6-year-old boy whose pre-B cells are incapable of translation to normal B cells
A 9-year-old girl who has a diagnosis of IgA deficiency
Question 3.
A nurse practitioner is teaching her colleagues about the role of cytokines in a variety of pathologies. Which of the following teaching points best captures an aspect of the functions and nature of cytokines?
“A particular cytokine can have varied effects on different systems, a fact that limits their therapeutic use.”
“Cytokine production is constant over time, but effects are noted when serum levels cross a particular threshold.”
“Most cytokines are produced by granular leukocytes, and different cells are capable of producing the same cytokine.”
“Cytokine actions are self-limiting in that activation of one precludes activation of other cytokines with similar actions.”
Question 4.
A 29-year-old construction worker got a sliver under his fingernail four days ago. The affected finger is now reddened, painful, swollen, and warm to the touch. Which of the following hematological processes is most likely occurring in response to the infection?
Proliferation of immature neutrophils
High circulatory levels of myeloblasts
Increased segmented neutrophil production
Phagocytosis by myelocytes
Question 5.
A 40-year-old woman who experiences severe seasonal allergies has been referred by her family physician to an allergist for weekly allergy injections. The woman is confused as to why repeated exposure to substances that set off her allergies would ultimately benefit her. Which of the following phenomena best captures the rationale for allergy desensitization therapy?
Repeated exposure to offending allergens binds the basophils and mast cells that mediate the allergic response.
Exposure to allergens in large, regular quantities overwhelms the IgE antibodies that mediate the allergic response.
Repeated exposure stimulates adrenal production of epinephrine, mitigating the allergic response.
Injections of allergens simulate production of IgG, which blocks antigens from combining with IgE.
Question 6.
A 22-year-old female who adheres to a vegan diet has been diagnosed with iron-deficiency anemia. Which of the following components of her diagnostic blood work would be most likely to necessitate further investigation?
Decreased mean corpuscular volume (MCV)
Decreased hemoglobin and hematocrit
Microcytic, hypochromic red cells
Decreased erythropoietin levels
Question 7.
Following a course of measles, a 5-year-old girl developed scattered bruising over numerous body surfaces and was diagnosed with immune thrombocytopenic purpura (ITP). As part of her diagnostic workup, blood work was performed. Which of the following results is most likely to be considered unexpected by the health care team?
Increased thrombopoietin levels
Decreased platelet count
Normal vitamin K levels
Normal leukocyte levels
Question 8.
As part of his diagnostic workup, a 77-year-old man’s nurse practitioner has ordered blood work that includes ferritin levels. The man is very interested in the details of his health care and is unfamiliar with ferritin and its role. He asks his nurse practitioner to explain the significance of it and the rationale for testing it. Which of the following explanations by the nurse practitioner is most accurate?
“Ferritin is the activated and usable form of iron that your red blood cells can use to transport oxygen.”
“Ferritin is a stored form of iron that indirectly shows me whether you would benefit from iron pills.”
“Ferritin is a protein-iron complex that allows your red blood cells to make use of the iron that you consume in your diet.”
“Ferritin is the form of iron that is transported in your blood plasma to the red blood cells that need it.”
Question 9.
A 23-year-old man has received a recent diagnosis of appendicitis following 24 hours of acute abdominal pain. The nurse practitioner providing care for the man is explaining that while it is unpleasant, the inflammation of his appendix is playing a role in his body’s fight against the underlying infectious process. Which of the following teaching points should the nurse practitioner eliminate from his teaching for the patient?
“Inflammation can help to remove the body tissue cells that have been damaged by infection.”
“Inflammation will start your body on the path to growing new, healthy tissue at the site of infection.
“Inflammation helps your body to produce the right antibodies to fight the infection.”
“Inflammation ultimately aids in eliminating the initial cause of the cell injury in your appendix.”
Question 10.
A 2-year-old girl has had repeated ear and upper respiratory tract infections since she was born. A pediatrician has determined a diagnosis of transient hypogammaglobulinemia of infancy. What is the physiological origin of the child’s recurrent infections?
Antibody production by plasma cells is compromised because of impaired communication between B and T cells.
The child had a congenital absence of immunoglobulin G (IgG) antibodies and her body is only slowly beginning to produce them independently.
The child was born with immunoglobulin A (IgA) and immunoglobulin (IgM) antibodies, suggesting intrauterine infection.
The child lacks the antigen presenting cells integral to normal B-cell antibody production.
Question 11.
A 66-year-old female patient has presented to the emergency department because of several months of intermittently bloody stools that has recently become worse. The woman has since been diagnosed with a gastrointestinal bleed secondary to overuse of nonsteroidal anti-inflammatory drugs that she takes for her arthritis. The health care team would realize that which of the following situations is most likely?
The woman has depleted blood volume due to her ongoing blood loss.
She will have iron-deficiency anemia due to depletion of iron stores.
The patient will be at risk for cardiovascular collapse or shock.
She will have delayed reticulocyte release.
Question 12.
A 16-year-old female has been brought to her primary care nurse practitioner by her mother due to the girl’s persistent sore throat and malaise. Which of the following facts revealed in the girl’s history and examination would lead the nurse practitioner to rule out infectious mononucleosis?
The girl has a temperature of 38.1°C (100.6°F) and has enlarged lymph nodes.
Her liver and spleen are both enlarged.
Blood work reveals an increased white blood cell count.
Chest auscultation reveals crackles in her lower lung fields bilaterally.
Question 13.
A 30-year-old man has spent 5 hours on a cross-country flight seated next to a passenger who has been sneezing and coughing, and the man has been inhaling viral particles periodically. Which of the following situations would most likely result in the stimulation of the man’s T lymphocytes and adaptive immune system?
Presentation of a foreign antigen by a familiar immunoglobulin
Recognition of a foreign MHC molecule
Recognition of a foreign peptide bound to a self MHC molecule
Cytokine stimulation of a T lymphocyte with macrophage or dendritic cell mediation
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.
Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.
Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.
The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
Discussion Questions (DQ)
Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.
Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
I encourage you to incorporate the readings from the week (as applicable) into your responses.
Weekly Participation
Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.
APA Format and Writing Quality
Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
I highly recommend using the APA Publication Manual, 6th edition.
Use of Direct Quotes
I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.
As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
It is best to paraphrase content and cite your source.
LopesWrite Policy
For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.
Late Policy
The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
I do not accept assignments that are two or more weeks late unless we have worked out an extension.
As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.
Communication
Communication is so very important. There are multiple ways to communicate with me:
Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
