MDC II TEST 2 COMPREHENSIVE TEST 2026
QUESTIONS WITH SOLUTIONS
◉ 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 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 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? Answer: metabolic acidosis.
◉ A client comes into the ED with respiratory acidosis. What type of
medication would the nurse likely administer? 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? 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? 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? Answer: Verify tube
placement with radiography
◉ Which patient statement alerts the nurse to perform a thorough
GI history and focused assessment?
A."I don't like the taste of spicy foods."
B."I got dentures four years ago."
C."I experience occasional constipation."
D."I take ibuprofen three times daily for arthritis." Answer: D. large
amounts of aspirin or NSAIDs can cause peptic ulcer disease and GI
bleeding.
◉ After abdominal surgery, which question should the nurse ask the
patient to determine whether peristaltic movement is returning?
A."Have you passed flatus?"
B."Are you hungry"
C."Do you have any nausea?"
D."Is your pain level manageable?" Answer: A). Passing gas is
evidence of peristaltic movement
