Questions & Verified Answers
1. A client is admitted with a serum potassium level of 6.2 mEq/L. Which EKG change is the
nurse most likely to observe?
A. Tall, peaked T waves
B. Prominent U waves
C. ST-segment depression
D. Shortened PR interval
Answer: A
Rationale: Hyperkalemia (K+ > 5.0) causes tall, peaked T waves, widened QRS complexes, and
prolonged PR intervals on an EKG due to rapid repolarization. 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. 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.
2. A patient with a history of COPD presents with a pH of 7.30 and a PaCO2 of 52 mmHg.
Which acid-base imbalance is occurring?
A. Metabolic Alkalosis
B. Respiratory Alkalosis
C. Metabolic Acidosis
D. Respiratory Acidosis
Answer: D
Rationale: A pH below 7.35 indicates acidosis, and a PaCO2 above 45 mmHg indicates a respiratory
cause, typical in COPD due to CO2 retention. 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 action when

3. The nurse is caring for a patient post-operatively who develops a temperature of 104 F,
muscle rigidity, and tachycardia. Which medication should be administered immediately?
A. Naloxone
B. Atropine
C. Dantrolene
D. Physostigmine
Answer: C
Rationale: These are classic signs of Malignant Hyperthermia, a surgical emergency treated with
Dantrolene, a skeletal muscle relaxant. 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. In practice, this guides the nurse to set priorities and protect the client from harm. Safety,
nutrition, and clear communication are frequent priorities.
4. Which assessment finding in a patient with hyponatremia is the highest priority for the
nurse?
A. Increased thirst
B. Muscle cramping
C. Dry mucous membranes
D. Confusion and lethargy
Answer: D
Rationale: Hyponatremia causes cerebral edema, leading to neurological changes such as confusion,
lethargy, and seizures, which are high-priority safety risks. 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. Understanding this helps the nurse notice early warning signs and act
