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:
A. Presentation of a foreign antigen by a familiar immunoglobulin
B. Recognition of a foreign MHC molecule
C. Cytokine stimulation of a T lymphocyte with macrophage or dendritic
cell mediation - Correct Answer: C. Cytokine stimulation of a T
lymphocyte with macrophage or dendritic cell mediation
5. A nurse practitioner is explaining to a 40-year-old male patient the damage
that Mycobacterium tuberculosis could do to lung tissue. Which of the
following phenomena would underlie the nurse practitioner's explanation?
- Correct Answer: Macrophages are unable to digest the bacteria,
resulting in immune granulomas.
6. 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? - Correct Answer: Antibody production by
plasma cells is compromised because of impaired communication between
B and T cells.

cells and becoming incorporated into the genomes of others.

ventricle, normal chamber volume, and a normal ejection fraction from the
heart. What is this patient's most likely diagnosis? - Correct Answer:
Aortic valve stenosis
10.An 81-year-old female patient of a long-term care facility has a history of
congestive heart failure. The nurse practitioner caring for the patient has
positioned her sitting up at an angle in bed and is observing her jugular
venous distention. Why is jugular venous distention a useful indicator for
the assessment of the patient's condition? - Correct Answer: Blood
backs up into the jugular vein because there are no valves at the point of
entry into the heart.
11.As part of the diagnostic workup for a male patient with a complex history
of cardiovascular disease, the care team has identified the need for a record
of the electrical activity of his heart, insight into the metabolism of his
myocardium, and physical measurements, and imaging of his heart. Which
of the following series of tests is most likely to provide the needed data for
his diagnosis and care? - Correct Answer: Echocardiogram, PET scan,
ECG
12.A patient is experiencing impaired circulation secondary to increased
systemic arterial pressure. Which of the following statements is the most
relevant phenomenon? - Correct Answer: High afterload because of
backpressure against the left ventricle
, 13.A 55-year-old male who is beginning to take a statin drug for his
hypercholesterolemia is discussing cholesterol and its role in health and
illness with his nurse practitioner. Which of the following aspects of
hyperlipidemia would the nurse practitioner most likely take into account
when teaching the patient? - Correct Answer: Cholesterol is a metabolic
waste product that the liver is responsible for clearing.
14.Which of the following assessment findings in a newly admitted 30-year-old
male patient would be most likely to cause his nurse practitioner to suspect
polyarteritis nodosa? - Correct Answer: The man's blood pressure is
178/102 and he has abnormal liver function tests.
15.A 6-year-old boy has been brought to the emergency department by
ambulance after his mother discovered that his heart rate was "so fast I
couldn't even count it." The child was determined to be in atrial flutter and
his mother is seeking an explanation from the health care team. Which of
the following points should underlie an explanation to the mother? -
Correct Answer: The child is experiencing a reentry rhythm in his right
atrium.
16.A 68-year-old male complains to his nurse practitioner that when he tests
his blood pressure using a machine at his pharmacy, his heart rate is nearly
always very low. At other times, he feels that his heart is racing, and it also
seems to pause at times. The man has also occasionally had
lightheadedness and a recent syncopal episode. What is this patient's most
likely diagnosis and the phenomenon underlying it? - Correct Answer:
Sick sinus syndrome as a result of a disease of his sinus node and atrial or
