Questions & Verified Answers
1. A patient presents with a serum potassium level of 6.2 mEq/L. Which electrocardiogram
(ECG) change should the nurse expect to see?
A. Prominent U waves
B. Prolonged PR interval
C. ST-segment depression
D. Tall, peaked T waves
Answer: D
Rationale: Hyperkalemia (potassium > 5.0 mEq/L) typically causes tall, peaked T waves, widened
QRS complexes, and potentially cardiac arrest. 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.
2. Which clinical manifestation is a hallmark sign of hypocalcemia?
A. Positive Trousseau’s sign
B. Polyuria
C. Shortened QT interval
D. Bone pain
Answer: A
Rationale: Trousseau’s sign (carpal spasm induced by inflating a blood pressure cuff) and Chvostek’s
sign are classic indicators of hypocalcemia. 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.

How should the nurse interpret these results?
A. Respiratory Acidosis
B. Metabolic Acidosis
C. Metabolic Alkalosis
D. Respiratory Alkalosis
Answer: A
Rationale: A low pH (<7.35) indicates acidosis, and a high PaCO2 (>45) indicates a respiratory cause.
The HCO3 is normal, indicating no compensation. 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.

and a rapidly rising temperature. What is the priority nursing action?
A. Administer IV fluids quickly
B. Increase the oxygen flow rate
C. Apply cooling blankets
D. Notify the surgeon and prepare Dantrolene
Answer: D
Rationale: These are classic signs of Malignant Hyperthermia. Dantrolene sodium is the specific
antidote required to treat this life-threatening complication. 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 help you decide the best nursing
