A 67-year-old male client with chronic respiratory acidosis from end-stage chronic obstructive pulmonary disease (COPD) is receiving oxygen at 1 L/min per nasal cannula. Which statement by the nurse best explains to the client's daughter how this therapy prevents respiratory depression.
"Your father's breathing effort is driven by lower oxygen levels."
"Your father's breathing effort is driven by a low carbon dioxide level."
"Your father will retain metabolic acids if the oxygen level is too high."
"Your father will breathe best when he has a moderately high oxygen level."
A client presents to the emergency department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40mmHg, PO2 63 mmHg, HCO3 23 mEq/L, and oxygen saturation (SaO2) 93%. The nurse concludes that which of the following represents the best analysis of the etiology of these ABGs?
Tuberculosis
Pneumonia
Pleural effusion
Hypoxia
When assessing a client with impaired oxygen perfusion from pulmonary emboli, the nurse would expect to note which symptoms? Select all that apply.
Warm, dry skin
Anxiety
Tachycardia
Dyspnea
Bradycardia
A client who is 1 day postoperative reports shortness of breath. The respiratory rate (RR) is 35 and slightly labored, and there are no breath sounds present in the right lung base. The nurse would suspect which of the following conditions?
Cor pulmonale
Atelectasis
Pulmonary embolus
Cardiac tamponade
A client with an acute case of pneumonia has a dry, hacking cough, temperature of 100.6F, white blood cell (WBC) count of 12,000/mm3, decreased breath counds and pain upon deep inhalation or coughing. Which of the following would indicate positive results after a respiratory treatment of normal saline, acetylcysteine (Mucomyst), and albuterol (Proventil)? Select all that apply.
Reduced crackles and moderate amount of productive sputum
Absent breath sounds in bases and normal breath sounds in upper lobes
Wheezing, nonproductive cough
Increased coughing but with thinner and easier to expectorate sputum
Reduced anxiety and verbalization of improved ability to breathe
