HESI EXIT FAMILY NURSE PRACTITIONER PRACTICE REGISTERED NURSE (APRN) FINAL EXAM 2.(2023/2024) 61. A patient has been diagnosed with severe iron deficiency anemia. During physical assessment for which of the following symptoms would the nurse assess to determine the patient’s oxygen status? Increased breathlessness but increased activity tolerance Decreased breathlessness and decreased activity tolerance Increased activity tolerance and decreased breathlessness Decreased activity tolerance and increased breathlessness Decreased activity tolerance and increased breathlessness Hypoxia occurs because of decreased circulating blood volume, which leads to decreased oxygen to muscles, causing fatigue, decreased activity tolerance, and a feeling of shortness of breath 62. A patient is admitted to the emergency department with suspected carbon monoxide poisoning. Even though the patient’s color is ruddy, not cyanotic, the nurse understands that the patient is at a risk for decreased oxygen-carrying capacity of blood because carbon monoxide does which of the following: Stimulates hyperventilation, causing respiratory alkalosis Forms a strong bond with hemoglobin, creating a functional anemia. Stimulates hypoventilation, causing respiratory acidosis Causes alveoli to overinflate, leading to atelectasis Forms a strong bond with hemoglobin, creating a functional anemia. Carbon monoxide strongly binds to hemoglobin, making it unavailable for oxygen binding and transport. 63. A 6-year-old boy is admitted to the pediatric unit with chills and a fever of 104°F (40°C). What physiological process explains why the child is at risk for developing dyspnea? Fever increases metabolic demands, requiring increased oxygen need. Blood glucose stores are depleted, and the cells do not have energy to use oxygen
