Questions & Verified Answers
1. A nurse is caring for a client with a potassium level of 2.8 mEq/L. Which EKG change
should the nurse expect to see?
A. Tall, peaked T-waves
B. Shortened QT interval
C. Prominent U-waves
D. Widened QRS complex
Answer: C
Rationale: Hypokalemia (potassium < 3.5 mEq/L) typically manifests on an EKG as flat or inverted
T-waves and the presence of prominent U-waves. Tall, peaked T-waves are associated with
hyperkalemia. 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.
In practice, this guides the nurse to set priorities and protect the client from harm. Safety, nutrition, and
clear communication are frequent priorities.
2. When applying wrist restraints to a client who is agitated, which action is most
appropriate by the nurse?
A. Tie the restraints to the side rails of the bed
B. Ensure the restraint is tight enough to prevent any movement
C. Use a quick-release knot to secure the restraints to the bed frame
D. Request a standing order for restraints for all confused patients
Answer: C
Rationale: Restraints must be secured to the bed frame (not the rails) using a quick- release knot for
safety in case of an emergency. Two fingers should fit between the restraint and 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. Remembering this point will

3. A client is diagnosed with Respiratory Acidosis. Which of the following ABG results
supports this diagnosis?
A. pH 7.50, PaCO2 30, HCO3 22
B. pH 7.30, PaCO2 50, HCO3 24
C. pH 7.32, PaCO2 35, HCO3 18
D. pH 7.48, PaCO2 40, HCO3 30
Answer: B
Rationale: Respiratory acidosis is characterized by a low pH (<7.35) and an elevated PaCO2 (>45).
Option A shows a low pH and high CO2 with a normal bicarbonate, indicating acute respiratory
acidosis. 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.
4. The nurse is preparing to administer NPH and Regular insulin in the same syringe. Which
step is performed first?
A. Draw up the NPH insulin first
B. Draw up the Regular insulin first
C. Inject air into the Regular vial
D. Inject air into the NPH vial
Answer: D
Rationale: When mixing insulin, the sequence is: inject air into NPH (cloudy), inject air into Regular
(clear), draw up Regular, then draw up NPH. Air goes into the cloudy vial first. 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. 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.
