Questions & Verified Answers
1. A nurse is caring for a client with a potassium level of 6.5 mEq/L. Which EKG change
should the nurse closely monitor for?
A. Prominent U-waves
B. ST-segment depression
C. Shortened PR interval
D. Peaked T-waves
Answer: D
Rationale: Hyperkalemia (potassium > 5.0 mEq/L) typically manifests on an EKG as tall, peaked
T-waves, widened QRS complexes, and prolonged PR intervals. 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. Understanding this helps the nurse notice early warning signs
and act before the problem gets worse. Early action often prevents bigger complications for the client.
2. Which arterial blood gas (ABG) result is indicative of uncompensated respiratory
acidosis?
A. pH 7.48, PaCO2 48, HCO3 30
B. pH 7.32, PaCO2 30, HCO3 18
C. pH 7.30, PaCO2 52, HCO3 24
D. pH 7.50, PaCO2 30, HCO3 22
Answer: C
Rationale: Respiratory acidosis is characterized by a low pH (<7.35) and an elevated PaCO2 (>45). If
the HCO3 is normal, it is uncompensated. 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. 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.

3. The nurse is assessing a client for Trousseau’s sign. Which electrolyte imbalance is this
associated with?
A. Hypocalcemia
B. Hypermagnesemia
C. Hypernatremia
D. Hypokalemia
Answer: A
Rationale: Trousseau’s sign (carpal spasm induced by inflating a BP cuff) and Chvostek’s sign are
classic clinical indicators of hypocalcemia. Exam questions often test whether you can pick the most
practical and safe choice for the client in real situations. Focus on what the nurse can actually do right
now. 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.
4. A client is admitted with severe diarrhea and dehydration. Which IV fluid should the nurse
anticipate administering to expand the extracellular fluid volume?
A. 0.45% Sodium Chloride
B. Dextrose 5% in 0.9% Sodium Chloride
C. 0.9% Sodium Chloride
D. Dextrose 10% in Water
Answer: C
Rationale: 0.9% Sodium Chloride (Normal Saline) is an isotonic solution used to increase extracellular
fluid volume due to blood loss, dehydration, or surgery. Exam questions often test whether you can
pick the most practical and safe choice for the client in real situations. Focus on what the nurse can
actually do right now. In practice, this guides the nurse to set priorities and protect the client from harm.
Safety, nutrition, and clear communication are frequent priorities.
