A patient is brought into the ED with respiratory depression. The patient has a history of
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




COPD. What acid-base imbalance is most likely? - correct answer✔✔Respiratory Acidosis. The
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




patient likely has a build-up of CO2, causing respiratory acidosis.
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




The nurse is evaluating the lab work of a patient who has uncontrolled metabolic acidosis.
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




Which lab result would result from this condition? ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




A) pH 7.4 ||\\//|| ||\\//||




B) PaO2 98 mm Hg ||\\//|| ||\\//|| ||\\//|| ||\\//||




C) bicarbonate 38 mEq/ L
||\\//|| ||\\//|| ||\\//|| ||\\//||




D) serum potassium 5.7 mEq/L - correct answer✔✔D) serum potassium 5.7 mEq/L. Serum
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




potassium increases during acidosis to try to buffer the acidic conditions. ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




The nurse is reviewing the standing orders for a patient who was admitted for evaluation of
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




chest pain. The patient has a history of chronic obstructive pulmonary disease (COPD) and
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




his laboratory results and assessment reveal that he has mild respiratory acidosis. The nurse
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




would question which order? ||\\//|| ||\\//|| ||\\//||




A.Encourage oral fluids ||\\//|| ||\\//||




B.Keep head of bed elevated ||\\//|| ||\\//|| ||\\//|| ||\\//||




C.Oxygen therapy at 4 L/min as needed ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




D.Bedrest with bathroom privileges only - correct answer✔✔C) Oxygen therapy at 4L/ Min as ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




needed. Oxygen therapy is often ordered for respiratory acidosis. However, COPD patients
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




have a difficult time off-loading carbon dioxide and giving too much oxygen can cause these
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




patients to have a decrease in respiratory drive, leading to respiratory arrest. ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




A client has acute alcohol intoxication. What acid-base imbalance is the client at risk for? -
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




correct answer✔✔metabolic acidosis. ||\\//|| ||\\//||

,A client comes into the ED with respiratory acidosis. What type of medication would the
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




nurse likely administer? - correct answer✔✔bronchodilators
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




A client comes into the ED with a high fever and is hyperventilating. His ABG results are pH

7.51, PaCO2 28 mm Hg, and HCO3 24 mEq/L. The nurse should identify that the client has
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




which acid-base imbalance? - correct answer✔✔Respiratory Alkalosis. Because the client is
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




breathing rapidly, he is exhaling excessive amounts of carbon dioxide. This loss of carbon
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




dioxide decreases the hydrogen ion level of the blood, causing the pH to increase and
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




resulting in respiratory alkalosis. ||\\//|| ||\\//|| ||\\//||




A nurse is caring for a client who has metabolic alkalosis. As the client compensates for this
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




ac

id-base imbalance, which of the following mechanisms should the nurse expect the client's
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




body to use? - correct answer✔✔Hypoventilation.
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




Hypoventilation is the mechanism that helps clients compensate for metabolic alkalosis. ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




A nurse is inserting an NG tube for a client who is beginning enteral feedings. What action
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




should the nurse take to verify tube placement before administering initial feeding? - correct
