Question 1
A client with chronic obstructive pulmonary disease
(COPD) is receiving oxygen at 2 L/min via nasal
cannula. Which assessment finding indicates that
the oxygen therapy is effective?
A) Respiratory rate of 26 breaths per minute
B) SpO2 of 92% on pulse oximetry
C) Use of accessory muscles during inspiration
D) Arterial PaCO2 of 58 mm Hg
Correct Answer: B
,Rationale: The goal of oxygen therapy in COPD is to
maintain SpO2 between 88% and 92% to provide
adequate tissue oxygenation without suppressing
the hypoxic drive. An SpO2 of 92% indicates
effective therapy. A respiratory rate of 26 is
elevated, accessory muscle use suggests respiratory
distress, and a PaCO2 of 58 mm Hg indicates
hypercapnia, which may be worsened by excessive
oxygen.
Question 2
A postoperative client reports sudden chest pain and
shortness of breath. The nurse notes tachycardia
and hypotension. Which action should the nurse
take first?
A) Administer prescribed analgesic
B) Apply continuous cardiac monitoring
C) Position the client in high-Fowler’s position
D) Prepare for thrombolytic therapy
Correct Answer: C
Rationale: The client’s symptoms suggest a
pulmonary embolism. Positioning the client in high-
Fowler’s position facilitates lung expansion and
,improves ventilation-perfusion matching. While
cardiac monitoring and thrombolytic therapy may
be indicated, the immediate priority is to optimize
respiratory status. Analgesia is not the first action.
Question 3
A client with diabetes mellitus type 2 is prescribed
metformin. Which laboratory value should the nurse
monitor closely to identify a potential adverse effect
of this medication?
A) Serum potassium
B) Serum creatinine
C) Serum sodium
D) Serum calcium
Correct Answer: B
Rationale: Metformin is excreted by the kidneys and
can accumulate in renal impairment, increasing the
risk of lactic acidosis. Serum creatinine reflects renal
function and should be monitored before and during
therapy. Electrolyte imbalances are less directly
associated with metformin.
, Question 4
The nurse is assessing a client with heart failure who
has been prescribed furosemide. Which finding
indicates that the medication is having the desired
therapeutic effect?
A) Decreased peripheral edema
B) Increased heart rate
C) Increased blood pressure
D) Decreased urine output
Correct Answer: A
Rationale: Furosemide is a loop diuretic used to
reduce fluid volume overload in heart failure.
Decreased peripheral edema indicates successful
diuresis and reduction of extracellular fluid.
Increased heart rate and hypotension may indicate
excessive diuresis, and decreased urine output
suggests ineffective therapy.
Question 5
A client is admitted with acute pancreatitis. Which
dietary intervention should the nurse anticipate
initiating?
A) Clear liquid diet
