Question 1
A nurse is caring for a patient with Clostridium difficile. Which infection control measure is most appropriate?
A. Apply alcohol-based hand rub after patient contact
B. Wear a N95 respirator when entering the room
C. Wash hands with soap and water after patient contact
D. Keep the door closed at all times
Answer: C
Rationale
Alcohol-based hand rubs are ineffective against C. diff spores; mechanical friction with soap and water is required to remove
them. 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 patient for orthostatic hypotension, the nurse should notify the provider if the systolic blood pressure
drops by at least:
A. 10 mmHg
B. 5 mmHg
C. 20 mmHg
D. 15 mmHg
Answer: C
Rationale
Orthostatic hypotension is defined as a drop in systolic BP of at least 20 mmHg or diastolic BP of at least 10 mmHg within 3
minutes of standing. 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
A nurse observes a pressure injury that has full-thickness skin loss with visible subcutaneous fat, but no bone or muscle
is exposed. How should this be staged?
A. Stage III
B. Stage II
C. Stage I
D. Stage IV
Answer: A
Rationale
Stage III involves full-thickness skin loss involving damage to or necrosis of subcutaneous tissue; bone, tendon, and muscle
are not yet exposed. 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.
