Question 1
A nurse is preparing to administer an intramuscular (IM) injection using the Z-track method. What is the primary
rationale for using this technique?
A. To prevent the medication from leaking into the subcutaneous tissue
B. To increase the speed of medication absorption into the bloodstream
C. To reduce the risk of hitting a major nerve during the injection
D. To decrease the amount of pain felt during the needle insertion
Answer: A
Rationale
The Z-track method creates a zigzag path that seals the medication within the muscle tissue, preventing irritation or staining of
the subcutaneous tissue. 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
Which assessment finding would lead the nurse to suspect a Stage 2 pressure injury?
A. Non-blanchable erythema of intact skin over a bony prominence
B. Partial-thickness loss of dermis presenting as a shallow open ulcer or serum-filled
C. Full-thickness skin loss with visible adipose tissue and epibole
D. Full-thickness tissue loss with exposed bone, tendon, or muscle
Answer: B
Rationale
Stage 2 involves partial-thickness loss of the dermis and may present as an intact or ruptured serum-filled blister or a shallow,
pink/red wound bed. 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 patient is receiving continuous enteral feedings via a nasogastric tube. Which nursing action is most critical to prevent
aspiration?
A. Flushing the tube with 30 mL of water every 4 hours
B. Monitoring the patient’s blood glucose levels twice daily
C. Checking the gastric residual volume every 12 hours
D. Maintaining the head of the bed at 30 to 45 degrees at all times
Answer: D
Rationale
Elevation of the head of the bed is the most effective nursing intervention to reduce the risk of reflux and subsequent
aspiration of enteral formula. 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.
