Questions & Verified Answers
1. A patient’s arterial blood gas (ABG) results are: pH 7.28, PaCO2 52 mm Hg, and HCO3 24
mEq/L. How should the nurse interpret these findings?
A. Metabolic acidosis
B. Respiratory alkalosis, partially compensated
C. Respiratory acidosis, uncompensated
D. Metabolic alkalosis
Answer: C
Rationale: A pH below 7.35 indicates acidosis. A PaCO2 above 45 indicates a respiratory cause.
Since the HCO3 is within the normal range (22-26), it is uncompensated respiratory acidosis.
Remembering this point will help you decide the best nursing action when similar questions appear on
the exam. Link the answer to the client’s current condition and risk level. This is important because the
nurse must choose the action that keeps the client safest while still meeting their basic needs. Always
think about safety first when answering these questions.
2. A nurse is caring for a patient with left-sided heart failure. Which clinical manifestation
should the nurse expect to find?
A. Crackles in the lungs
B. Peripheral edema
C. Jugular venous distention
D. Splenomegaly
Answer: A
Rationale: Left-sided heart failure causes blood to back up into the pulmonary system, leading to
pulmonary congestion and crackles. Options A, B, and D are signs of right-sided heart failure. Knowing
the reason behind the correct answer makes it easier to rule out the wrong options quickly. Look for
the choice that protects the client and matches the priority need. Clear understanding of this concept
improves both test performance and everyday clinical judgment. Practice applying it to short case
scenarios to lock the idea in place.

Which EKG change is most likely associated with this finding?
A. ST-segment depression
B. Prominent U waves
C. Tall, peaked T waves
D. has a serum potassium level of 6.8 mEq/L. Which EKG change is most likely associated with this
finding?
Answer: C
Rationale: Hyperkalemia (K+ > 5.0) typically causes tall, peaked T waves and widened QRS
complexes. Knowing the reason behind the correct answer makes it easier to rule out the wrong
options quickly. Look for the choice that protects the client and matches the priority need. Knowing the
