Question 1 1 out of 1 points Describe 3 different nursing actions that could increase oxygenation in a client with pneumonia and an acid base imbalance. Selected Answer: 1. Administer high flow oxygen therapy prn by face mask or at 5 to 6 L/min to improve oxygen exchange. 2. Administer bronchodilators such as albuterol to open the airways 3. Reposition the patient frequently to prevent the pooling of respiratory secretions and to allow for better airway clearance. Correct Answer: position with head of bed elevated, oxygen , encourage cough and deep breathing, medication administration-be specific as to which meds  Question 2 1 out of 1 points Arterial blood gas levels are obtained for the client. If the client’s results are pH 7.48, CO2 42 mm Hg, and HCO3 32 mEq/L, the client is exhibiting which one of the following acid-base imbalances? Selected Answer: Metabolic alkalosis Answers: Metabolic acidosis Respiratory acidosis Respiratory alkalosis Metabolic alkalosis  Question 3 0.7 out of 1 points Analyze the following arterial blood gases (ABGs): pH 7.31, PaCO2 48mmHg, HCO3 26meq/L, PaO2 55mmHg. Interpret the ABGs and discuss what is the most serious complication that you anticipate? Selected The client is experiencing respiratory acidosis. The most serious complication Answer: of this would be a dangerously low respiratory rate or hypoventilation. The client will also not be breathing out enough CO2 and will be hypercapnic, which is what makes the pH low/acidic. Correct Answer: [None]  Question 4 1 out of 1 points The nurse is aware that the compensating mechanism that is most likely to occur in the presence of respiratory acidosis is: Selected Answer: Retention of HCO3 by the kidneys to increase the pH level Answers: Hyperventilation to decrease the CO2 levels Hypoventilation to increase the CO2 levels Retention of HCO3 by the kidneys to increase the pH level Excretion of HCO3 by the kidneys to decrease the pH level  Question 5 1 out of 1 points In a client with diabetic ketoacidosis, which of the following arterial blood gas results demonstrates the greatest impairment in oxygenation? Selected Answer: pH 7.14, PaCO2 47 mm Hg, HCO3 19 mEq/L, PaO2 40 mm Hg Answers: pH 7.14, PaCO2 47 mm Hg, HCO3 19 mEq/L, PaO2 40 mm Hg pH 7.22, PaCO2 55mm Hg, HCO3 29 mEq/L, PaO2 80 mm H pH 7.36, PaCO2 45mm Hg, HCO3 22 mEq/L, PaO2 75 mm Hg pH 7.46, PaCO2 45mm Hg, HCO3 29 mEq/L, PaO2 72 mm Hg  Question 6 1 out of 1 points Of all of the following clients, the nurse recognizes that the individual who is most at risk for an acid base imbalance is: Selected Answer: A thirty year female with uncontrolled diabetes type I Answers: A 27 year old female smoker An 80 year old male with a recent hip fracture A thirty year female with uncontrolled diabetes type I A 52 year old male with stage I heart failure  Question 7 0 out of 1 points A client with COPD and a new diagnosis of pneumonia is admitted to the hospital. Arterial blood gas levels are drawn. The nurse anticipates which of the following arterial blood gas results? Selected Answer: pH 7.53, PaCO2 35 mm Hg, HCO3 24 mEq/L Answers: pH 7.34, PaCO2 37 mm Hg, HCO3 19 mEq/L pH 7.22, PaCO2 54 mm Hg, HCO3 20 mEq/L pH 7.53, PaCO2 35 mm Hg, HCO3 24 mEq/L pH 7.53, PaCO2 35 mm Hg, HCO3 24 mEq/L  Question 8 0.7 out of 1 points Based on the following vital signs results, describe what may be happening to the client. BP 148/81 HR 118 Respiratory Rate 26 PaO2 60mm Hg SaO2 90% Selected Answer: Hyperventilation (tachypnea) due to fright or anxiety? Correct Answer: the client has elevated BP, HR, RR, and decreased sao2 and paO2 . The client may be in pain or anxious and needs supplemental oxygen to increase the PaO2.  Question 9 1 out of 1 points A homeless client is brought into the emergency department with indications of extremely poor nutrition. Arterial blood gas levels are assessed, and the nurse anticipates that this client will demonstrate which of the following results? Selected Answer: pH 7.3, PaCO2 38 mm Hg, HCO3 19 mEq/L Answers: pH 7.3, PaCO2 38 mm Hg, HCO3 19 mEq/L pH 7.5, PaCO2 34 mm Hg, HCO3 20 mEq/L pH 7.35, PaCO2 35 mm Hg, HCO3 24 mEq/L pH 7.52, PaCO2 48 mm Hg, HCO3 28
