Questions & Verified Answers
1. A patient’s arterial blood gas (ABG) results show pH 7.28, PaCO2 55 mmHg, and HCO3 26
mEq/L. Which condition does the nurse suspect?
A. Metabolic Acidosis
B. Metabolic Alkalosis
C. Respiratory Acidosis
D. Respiratory Alkalosis
Answer: C
Rationale: The pH is low (<7.35), indicating acidosis. The PaCO2 is high (>45), and the HCO3 is
normal, indicating the respiratory system is the cause. 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.
2. Which clinical manifestation should the nurse prioritize when assessing a patient with a
potassium level of 6.2 mEq/L?
A. Increased bowel sounds
B. Tall, peaked T waves on ECG
C. Muscle weakness
D. Hyperactive deep tendon reflexes
Answer: B
Rationale: Hyperkalemia can lead to life-threatening cardiac dysrhythmias, which are reflected on the
ECG as tall, peaked T waves. In practice, this guides the nurse to set priorities and protect the client
from harm. Safety, nutrition, and clear communication are frequent priorities. 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.

3. The nurse is performing Trousseau’s sign to check for hypocalcemia. Which action
indicates the correct technique?
A. Tapping the facial nerve in front of the ear
B. Inflating a blood pressure cuff above systolic pressure for 3 minutes
C. Asking the patient to hyperventilate for 30 seconds
D. Observing for carpal spasm after inflating a blood pressure cuff
Answer: D
Rationale: Trousseau’s sign is assessed by inflating a BP cuff above the systolic pressure; a positive
result is a carpal spasm. 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. This
knowledge supports safe care and helps the nurse teach the client and family clearly and simply. Clear
teaching improves cooperation and reduces anxiety.
4. A client is being prepared for surgery. Which medication should the nurse identify as a
potential trigger for malignant hyperthermia?
A. Succinylcholine
B. Propofol
C. Fentanyl
D. Midazolam
Answer: A
Rationale: Malignant hyperthermia is often triggered by volatile gaseous inhalation anesthetics and
succinylcholine, a neuromuscular blocking agent. 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. 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.
