She has subsequently been diagnosed with Rocky Mountain spotted fever, a pathology caused by Rickettsiaceae. Which of the followed statements best captures a characteristic trait of Rickettsiaceae? Question options: They are eukaryotic. They have both RNA and DNA. They have a distinct spiral-shaped morphology. They are neither gram-negative nor gram-positive. Question 2 1 / 1 point A 60-year-old male patient with an acute viral infection is receiving interferon therapy. The nurse practitioner is teaching the family of the patient about the diverse actions of the treatment and the ways that it differs from other anti-infective therapies. Which of the following teaching points should the nurse practitioner exclude? Question options: “Interferon can help your father's unaffected cells adjacent to his infected cells produce antiviral proteins that limit the spread of the infection.” “Interferon can help limit the replication of the virus that's affecting your father.” “Interferon helps your father's body recognize infected cells more effectively.” “Interferon can bolster your father's immune system by stimulating natural killer cells that attack viruses.” Question 3 1 / 1 point The blood work of a 44-year-old male patient with a diagnosis of liver disease secondary to alcohol abuse indicates low levels of albumin. Which of the following phenomena would a clinician be most justified in anticipating? Question options: Impaired immune function Acid-base imbalances Impaired thermoregulation Fluid imbalances Question 4 1 / 1 point 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? Question options: Proliferation of immature neutrophils High circulatory levels of myeloblasts Increased segmented neutrophil production Phagocytosis by myelocytes Question 5 1 / 1 point 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? Question options: 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 Question 6 1 / 1 point A 24-year-old woman presents with fever and painful, swollen cervical lymph nodes. Her blood work indicates neutrophilia with a shift to the left. She most likely has: Question options: A mild parasitic infection A severe bacterial infection A mild viral infection A severe fungal infection Question 7 1 / 1 point 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? Question options: 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 8 0 / 1 point A patient has been admitted to an inpatient medical unit of a hospital with an acute viral infection. The health care team providing care for the patient would recognize which of the following statements as an accurate description of the role of viruses in human infections? Question options: Viruses have limited or absent genetic material of their own. Some viruses are capable of transforming normal host cells into malignant cells. Viruses are often implicated in cases of transmissible neurodegenerative disease. Viruses require stimulation after a latent period before they are able to produce symptoms. Question 9 1 / 1 point 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? Question options: 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 10 1 / 1 point 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? Question options: “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.”
