Question 1
A nurse is caring for a patient with a pressure injury that has full-thickness skin loss involving damage to the
subcutaneous tissue, but no bone, tendon, or muscle is visible. How should the nurse document this stage?
A. Stage 2
B. Stage 3
C. Stage 4
D. Unstageable
Answer: B
Rationale
Stage 3 involves full-thickness skin loss where subcutaneous fat may be visible, but bone, tendon, and muscle are not
exposed. Stage 4 involves exposed bone or muscle. 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
When assessing a post-operative patient’s surgical incision, the nurse notes the edges are separated and the
underlying visceral organs are protruding. What is the nurse’s immediate priority?
A. Call the surgeon immediately and prepare for emergency surgery.
B. Cover the wound with sterile towels moistened with sterile normal saline.
C. Apply a dry sterile dressing to the area.
D. Push the organs back into the abdominal cavity gently.
Answer: B
Rationale
Evisceration is a medical emergency. The nurse should cover the protruding organs with sterile towels soaked in sterile normal
saline to keep them moist and prevent infection before calling the surgeon.
Question 3
A patient is admitted with a potassium level of 2.8 mEq/L. Which clinical manifestation should the nurse monitor for
most closely?
A. Tetany and muscle spasms
B. Positive Chvostek’s sign
C. Cardiac dysrhythmias
D. Hyperactive deep tendon reflexes
Answer: C
Rationale
Hypokalemia (low potassium) significantly impacts cardiac conduction and can lead to life-threatening dysrhythmias.
Chvostek’s sign is related to hypocalcemia. 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.
