Question 1
A nurse is preparing a patient for surgery. Who is legally responsible for obtaining the patient’s informed consent?
A. The surgeon performing the procedure
B. The preoperative nurse
C. The hospital administrator
D. The anesthesiologist
Answer: A
Rationale
While nurses may witness the signature, the legal responsibility to explain the risks, benefits, and alternatives of the procedure
lies solely with the provider performing it. Understanding this concept is essential for safe clinical decision-making. Incorrect
choices often reflect common misconceptions. Always link assessment findings to the primary process and anticipated
complications.
Question 2
A patient presents with a serum potassium level of 2.8 mEq/L. Which EKG finding should the nurse anticipate?
A. Tall, peaked T waves
B. Widened QRS complex
C. Presence of U waves
D. Shortened PR interval
Answer: C
Rationale
Hypokalemia (potassium < 3.5 mEq/L) is associated with the development of U waves and ST-segment depression. Peaked T
waves are characteristic of hyperkalemia. Understanding this concept is essential for safe clinical decision-making. Incorrect
choices often reflect common misconceptions. Always link assessment findings to the primary process and anticipated
complications.
Question 3
Which electrolyte imbalance is most commonly associated with a positive Chvostek’s sign?
A. Hypermagnesemia
B. Hypocalcemia
C. Hyponatremia
D. Hyperkalemia
Answer: B
Rationale
Chvostek’s sign (facial twitching when the facial nerve is tapped) is a clinical indicator of hypocalcemia or hypomagnesemia
due to increased neuromuscular irritability. Understanding this concept is essential for safe clinical decision-making. Incorrect
choices often reflect common misconceptions. Always link assessment findings to the primary process and anticipated
complications.
