Question 1
A nurse is preparing to perform a sterile dressing change. Which action would result in the contamination of the sterile
field?
A. Opening the outermost flap of the sterile kit away from the body.
B. Holding sterile forceps above the level of the waist.
C. Placing sterile items at least 1 inch inside the border of the field.
D. Reaching over the sterile field to pick up a gauze pad.
Answer: D
Rationale
Reaching over a sterile field violates the principle of surgical asepsis as microorganisms from clothing or skin can fall onto the
field. The 1-inch border is considered contaminated, and items must be kept above the waist.
Question 2
A patient is at risk for developing pressure injuries. Which Braden Scale score would indicate the highest level of risk?
A. 20
B. 16
C. 9
D. 13
Answer: C
Rationale
In the Braden Scale, a lower score indicates a higher risk for pressure injury development. A score of 9 represents ‘very high
risk,’ while scores closer to 23 indicate low or no risk. 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 clinical manifestation is considered an early sign of hypoxia in a patient with respiratory distress?
A. Restlessness and agitation
B. Cyanosis of the mucous membranes
C. Bradypnea
D. Clubbing of the fingers
Answer: A
Rationale
Restlessness, anxiety, and agitation are early signs of hypoxia as the brain is sensitive to decreasing oxygen levels. Cyanosis
is a late sign, and clubbing is a sign of chronic hypoxia. 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.
