MN551- unit 4 quiz Question 1. 1. A 66-year-old male presents to the emergency department accompanied by his wife who claims that he has been acting confused. The man is complaining of a sudden onset of severe weakness and malaise and has a dry cough and diarrhea. His temperature is 102.8°F and his blood work indicates his sodium level is 126 mEq/L (normal is 135 to 145 mEq/L). What will be the assessing nurse practitioner's most likely suspicion? (Points : 0.4) Bronchopneumonia Mycoplasma pneumonia Legionnaire disease Pneumococcal pneumonia Question 2. 2. A 51-year-old female patient who is 2 days postoperative on a surgical unit of a hospital is at risk for developing atelectasis as a result of being largely immobile. Which of the following teaching points by her nurse practitioner is most appropriate?(Points : 0.4) “Being in bed increases the risk of fluid accumulating between your lungs and their lining, so it's important for you to change positions often.” “You should breathe deeply and cough to help your lungs expand as much as possible while you're in bed.” “Make sure that you stay hydrated and walk as soon as possible to avoid our having to insert a chest tube.” “I'll prescribe bronchodilator medications that will help open up your airways and allow more oxygen in.” Question 3. 3. Which of the following situations would be most deserving of a pediatrician's attention? (Points : 0.4) The mother of an infant 2 days postpartum notes that her baby has intermittent periods of hyperventilation followed by slow respirations or even brief periods of apnea. A volunteer in the nursery notes that one of the infants, age 2 weeks, appears unable to breathe through his mouth, even when his nose is congested. A neonate is visibly flaring her nostrils on inspiration. A midwife notes that a newborn infant's chest is retracting on inspiration and that the child is grunting. Question 4. 4. A 77-year-old lifetime smoker has been diagnosed with a tumor in his lung at the site of an old tubercle scarring site, located in a peripheral area of his bronchiolar tissue. What is this patient's most likely diagnosis? (Points : 0.4) Squamous cell carcinoma Small cell lung cancer Large cell carcinoma Adenocarcinoma Question 5. 5. Which of the following phenomena is most likely occurring during a child's alveolar stage of lung development? (Points : 0.4) Terminal alveolar sacs are developing and surfactant production is beginning. A single-capillary network exists and the lungs are capable of respiration. The conducting airways are formed, but respiration is not yet possible. Primitive alveoli are formed and the bronchi and bronchioles become much larger. Question 6. 6. Which of the following residents of a long-term care facility is most likely to be exhibiting the signs and symptoms of chronic obstructive pulmonary disease (COPD)? (Points : 0.4) A 79-year-old lifetime smoker who is complaining of shortness of breath and pain on deep inspiration An 81-year-old smoker who has increased exercise intolerance, a fever, and increased white blood cells An 81-year-old male who has a productive cough and recurrent respiratory infections An 88-year-old female who experiences acute shortness of breath and airway constriction when exposed to tobacco smoke Question 7. 7. Following a winter power outage, a patient who had been using a home gasoline generator began to experience dizziness and headaches and was diagnosed with carbon monoxide poisoning. What is the goal of hyperbaric oxygen treatment for carbon monoxide poisoning?(Points : 0.4) To increase the amount of oxygen dissolved in plasma To increase the production of unbound hemoglobin To stimulate the release of oxygen at the capillaries To remove bound CO from hemoglobin Question 8. 8. A male lifetime smoker has died as a result of chronic obstructive pulmonary disease.

(Points : 0.4) Proliferation of natural killer (NK) cells in the alveolar lumen Large numbers of alveolar macrophages in septal connective tissue The presence of tubercles in the intra-alveolar spaces Compensatory regeneration of type I alveolar cells Question 9. 9. A 44-year-old woman developed calf pain during a transatlantic flight followed by acute shortness of breath upon arrival at her destination. She was subsequently diagnosed with a pulmonary embolism (PE), which resolved with anticoagulant therapy. Which of these statements best characterizes the underlying problem of her PE? (Points : 0.4) She was short of breath because ventilation was occurring but perfusion was inadequate. The combination of normal perfusion but compromised ventilation caused hypoxia. She developed a transient anatomic shunt resulting in impaired oxygenation. Impaired gas diffusion across alveolar membranes resulted in dyspnea and hypoxia. Question 10. 10. A 21-year-old male patient has suffered a head injury during a crash on his motorcycle, and a deficit that assessments have revealed is an impaired swallowing mechanism. He has also developed aspiration pneumonia. Which of the following statements most accurately capture an aspect of his condition? (Points : 0.4) His oropharynx is obstructed. His epiglottis is covering his larynx His vocal folds have been compromised. His tracheobronchial tree is intermittently obstructed. Question 11. 11. As a consequence of long-standing lung disease, a patient is in a chronic state of hypoxia. Which of the following phenomena would the patient's nurse practitioner be most justified in anticipating? Select all that apply: (Points : 0.4) Metabolic alkalosis Increased erythropoietin production Pulmonary vasodilation Hyperventilation A shift to the right of the oxygen-hemoglobin dissociation curve Personality changes Question 12. 12. The mother of a 7-year-old boy who has recently been diagnosed with childhood asthma has come to the education center to learn more about her son's condition. Which of the following teaching points is most justifiable? (Points : 0.4) “Research has shown that viruses may actually be a factor in many children's asthma.” “The most reliable indicator that your child is having an asthma attack is audible wheezing.” “Steroids that your child can inhale will likely be the first line of defense. “Your son will likely need to limit or avoid exercise and sports.” Question 13. 13. Which of the following statements best conveys an aspect of the respiratory pressures that govern ventilation? (Points : 0.4) Intrapleural pressure slightly exceeds that of the inflated lung The chest wall exerts positive pressure on the lungs that contributes to expiration The lungs are prevented from collapsing by constant positive intrapulmonary pressure Negative intrapleural pressure holds the lungs against the chest wall Question 14. 14. A premature infant on mechanical ventilation has developed bronchopulmonary dysplasia (BPD) and is showing signs and symptoms of hypoxemia, low lung compliance, and respiratory distress syndrome (RDS). Which of the following is the most likely contributor to the infant's present health problem? (Points : 0.4) High inspired oxygen concentration and injury from positive-pressure ventilation Failure to administer corticosteroids to the infant in utero Insufficient surfactant production and insufficient surfactant therapy Insufficient supplemental oxygen therapy Question 15. 15.

A female patient is requiring supplementary oxygen by facemask due to her reduced lung compliance. Which of the following pathophysiologic processes is most likely to be a contributor to her low lung compliance? (Points : 0.4) The woman's lungs have more recoil than a healthy person's. Her type II alveolar cells are producing a slight excess of surfactant. Turbulent airflow is taking place in the patient's large airways. Her thoracic cage is less flexible than when she was healthy. Question 20. 20. A 71-year-old woman is dependent on oxygen therapy and bronchodilators due to her diagnosis of emphysema. Which of the following processes would her care team be most justified in ruling out?
