Questions & Verified Answers
1. A nurse is caring for a client with a potassium level of 2.8 mEq/L. Which assessment
finding should the nurse prioritize?
A. Hyperactive bowel sounds
B. Positive Chvostek’s sign
C. Increased muscle strength
D. Irregular heart rhythm
Answer: D
Rationale: Hypokalemia (potassium < 3.5 mEq/L) can lead to life-threatening cardiac dysrhythmias
and ECG changes like U-waves. Chvostek’s sign is associated with hypocalcemia. 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 consistent with a client experiencing
hyperventilation due to anxiety?
A. pH 7.30, PaCO2 50, HCO3 24
B. pH 7.50, PaCO2 40, HCO3 30
C. pH 7.32, PaCO2 38, HCO3 18
D. pH 7.48, PaCO2 30, HCO3 22
Answer: D
Rationale: Hyperventilation causes excessive loss of CO2, leading to Respiratory Alkalosis (high pH,
low PaCO2). 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. 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.

3. A nurse is assessing an IV site and finds it cool to the touch, swollen, and the client
reports pain. Which complication is most likely?
A. Phlebitis
B. Extravasation
C. Infiltration
D. Thrombosis
Answer: C
Rationale: Infiltration is characterized by coolness, swelling, and pallor at the site. Phlebitis would be
warm and red. 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. 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.
4. When administering an intramuscular injection using the Z-track method, what is the
primary purpose of this technique?
A. To prevent the medication from leaking into the subcutaneous tissue
B. To ensure the medication enters the subcutaneous tissue
C. To decrease the speed of absorption
D. To eliminate the need for aspiration
Answer: A
Rationale: The Z-track method seals the medication within the muscle and prevents tracking/leakage
into sensitive subcutaneous tissue. This knowledge supports safe care and helps the nurse teach the
client and family clearly and simply. Clear teaching improves cooperation and reduces anxiety. 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.
