QUESTION WITH ANSWERS AND RATIONALES
A nurse knows that patient education has been effective when the
patient states:
“I will rotate the location where I give myself injections.” Which
statement indicates understanding of the Z-track method?
A. “I will rotate injection sites each time.”
B. “The last shot like that turned my skin colors.”
C. “I will massage the area after injection.”
D. “I should inject into fatty tissue only.”
Correct Answer: B
Expert Rationale:
The Z-track method is used to prevent medication leakage into
subcutaneous tissue, especially with irritating or staining medications. A
key indication is previous skin discoloration or irritation at injection
,sites. This suggests the need for a technique that prevents medication
tracking into the dermis.
Option A refers to site rotation, not Z-track indication. Option C is
incorrect because massage is avoided in Z-track technique. Option D
describes general subcutaneous injections, not Z-track use.
DIF: Application
REF: Medication Administration / IM Injections
OBJ: Identify indication for Z-track technique

A 2-year-old child is ordered to have ear irrigation performed daily. The
nurse correctly performs the procedure by:
A. Pulling the auricle up and back
B. Pulling the auricle down and back
C. Keeping the ear canal straight without manipulation
D. Pulling the tragus forward
Correct Answer: B
Expert Rationale:
In children under 3 years of age, the ear canal is straightened by pulling
the auricle down and back to facilitate safe irrigation. This accounts for
anatomical differences compared to adults.
Option A is used for adults. Options C and D do not properly straighten
the canal.
DIF: Knowledge
REF: Pediatric Procedures
,OBJ: Apply age-appropriate ear irrigation technique

A patient has an order for 10 units of U-50 insulin using a U-100 syringe.
How many units should be administered?
A. 5 units
B. 10 units
C. 20 units
D. 25 units
Correct Answer: C
Expert Rationale:
U-50 insulin contains 50 units/mL, while U-100 syringes are calibrated
for 100 units/mL. To deliver 10 units of U-50 insulin, the nurse must
adjust for concentration, resulting in drawing up 20 units on a U-100
syringe.
DIF: Application
REF: Pharmacology / Insulin Administration
OBJ: Perform insulin dosage conversion
TOP: Medication Administration / Safety
A patient has an order for 20 units of U-50 insulin using a U-100 syringe.
How many mL should the nurse administer?
A. 0.1 mL
B. 0.2 mL
, C. 0.4 mL
D. 0.5 mL
Correct Answer: C
Expert Rationale:
U-50 insulin contains 50 units per mL. Therefore, 20 units equals 0.4 mL
(20 ÷ 50 = 0.4). Accurate conversion prevents dosing errors.
DIF: Application
REF: Pharmacology / Insulin Calculation
OBJ: Convert insulin units to mL
TOP: Medication Safety / Dosage Calculation
The patient is receiving phenytoin (Dilantin) at 0900. When should the
trough level be drawn?
A. 0800
B. 0830
C. 0900
D. 0930
Correct Answer: B
Expert Rationale:
A trough level is drawn immediately before the next scheduled dose to
measure the lowest drug concentration. Drawing at 0830 ensures an
accurate pre-dose level for a 0900 administration.
