The NP recognizes that which of the following phenomena has caused the tissue damage? (Points : 2) Decreased blood viscosity has resulted in interstitial bleeding. Reactive vasodilation has compromised perfusion. Autonomic nervous stimulation has resulted in injury. Decreased blood flow has induced hypoxia. Question 2.2. 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? (Points : 2) The child is experiencing a reentry rhythm in his right atrium. The resolution of the problem is dependent on spontaneous recovery and is resistant to pacing interventions. The child is likely to have a normal ECG apart from the rapid heart rate. The boy's atria are experiencing abnormal sympathetic stimulation. Question 3.3. A 14-year-old boy has been diagnosed with infectious mononucleosis. Which of the following pathophysiological phenomena is most responsible for his symptoms? (Points : 2) The Epstein-Barr virus (EBV) is lysing many of the boy's neutrophils. Viruses are killing some of his B cells and becoming incorporated into the genomes of others. The EBV inhibits the maturation of white cells within his peripheral lymph nodes. The virus responsible for mononucleosis inhibits the maturation of myeloblasts into promyelocytes. Question 4.4. A patient has suffered damage to his pericardium following a motor vehicle accident. Which of the following consequences should the nurse practitioner be most likely to rule out? (Points : 2) Impaired physical restraint of the left ventricule Increased friction during the contraction/relaxation cycle Reduced protection from infectious organisms Impaired regulation of myocardial contraction Question 5.5. Sputum samples from a patient with pneumonia contain an infective agent that has a peptidoglycan cell wall, expresses endotoxins, replicates readily in broth and on agar, grows in clusters, has pili, and does not stain when exposed to crystal violet. This pneumonia is most likely: (Points : 2) Chlamydial Viral Mycoplasmal Bacterial Question 6.6. A nurse practitioner student is familiarizing herself with the overnight admissions to an acute medical unit of a university hospital. Which of the following patients would the student recognize as being least likely to have a diagnosis of antiphospholipid syndrome in his or her medical history?

A number of patients have presented to the emergency department in the last 24 hours with complaints that are preliminarily indicative of myocardial infarction. Which of the following patients is least likely to have an ST-segment myocardial infarction (STEMI)? (Points : 2) A 70-year-old woman who is complaining of shortness of breath and vague chest discomfort A 66-year-old man who has presented with fatigue, nausea and vomiting, and cool, moist skin A 43-year-old man who woke up with substernal pain that is radiating to his neck and jaw A 71-year-old man who has moist skin, fever, and chest pain that is excruciating when he moves but relieved when at rest - - - - - - - - - - Question 43.43. As a result of dehydration, a patient's epithelial cells are producing insufficient amounts of mucus. Consequently, the patient's mucociliary blanket is compromised. Which of the following changes would a care provider most reasonably anticipate as a direct result of this change? (Points : 2) Impaired function of the patient's cilia Decreased levels of oxygen saturation Increased amounts of bacteria in the lungs Increased carbon dioxide levels Question 44.44. An 87-year-old male resident of an assisted living facility has been consistently continent of urine until the last several weeks. Which of the following actions by the care providers at the facility is the most likely priority? (Points : 2) Performing a physical examination and history to determine the exact cause and character of the incontinence Providing patient education focusing on the fact that occasional incontinence is a normal, age-related change Teaching the resident about protective pads, collection devices, and medications that may be effective Showing the resident the correct technique for exercises to improve bladder, sphincter, and pelvic floor tone Question 45.45. A patient who presented with shortness of breath and difficulty climbing stairs has been diagnosed with pulmonary fibrosis, a disease characterized by scarring of the alveoli.
