NURS 101L Fundamentals of Nursing Skills Lab - Module Exam 4 2026
|WCU
1. When administering an intramuscular (IM) injection using the Z-track
method, what is the primary purpose of this technique?
A. To ensure the medication reaches the bone for faster absorption
B. To decrease the amount of pain felt by the patient during needle insertion
C. To prevent the medication from leaking back into the subcutaneous tissue
D. To allow for a larger volume of medication to be injected into the deltoid
Answer: C
Rationale: The Z-track method is used in IM injections to seal the medication in the muscle
and prevent it from tracking back into the sensitive subcutaneous tissue, which reduces
irritation.
2. A nurse is preparing to administer an intradermal injection for a TB skin test.
At what angle should the needle be inserted?
A. 45 degrees
B. 5 to 15 degrees
C. 90 degrees
D. 30 degrees
Answer: B
Rationale: Intradermal injections are administered at a shallow angle of 5 to 15 degrees to
ensure the medication is deposited just below the epidermis.
,3. Which of the following is the preferred site for a high-volume intramuscular
injection in an adult?
A. Dorsogluteal
B. Deltoid
C. Ventrogluteal
D. Rectus femoris
Answer: C
Rationale: The ventrogluteal site is preferred because it is deep, away from major nerves
and blood vessels, and can accommodate larger volumes of medication.
4. When mixing Regular and NPH insulin in one syringe, which step should the
nurse perform first after injecting air into both vials?
A. Draw up the NPH insulin
B. Draw up the Regular insulin
C. Shake the Regular insulin vial
D. Recap the needle before drawing any insulin
Answer: B
Rationale: To prevent contaminating the fast-acting (Regular) insulin with the long-acting
(NPH) insulin, the clear (Regular) insulin must always be drawn into the syringe first.
5. A patient’s IV site is cool to the touch, swollen, and the infusion has slowed.
Which complication should the nurse suspect?
A. Phlebitis
B. Extravasation
C. Infiltration
D. Infection
Answer: C
Rationale: Infiltration occurs when non-vesicant IV fluid leaks into the surrounding tissue,
causing coolness, pallor, and edema at the site.
, 6. How should a nurse pull the pinna when administering ear drops to a 4-year-
old child?
A. Up and back
B. Down and back
C. Straight back
D. Down and forward
Answer: A
Rationale: For adults and children over 3 years old, the pinna is pulled up and back to
straighten the ear canal. For infants/toddlers under 3, it is pulled down and back.
7. Before administering a bolus tube feeding through a nasogastric (NG) tube,
what is the most reliable bedside method to verify placement?
A. Checking the pH of aspirated gastric contents
B. Auscultating air injected into the stomach
C. Observing the color of the aspirate
D. Checking the length of the tube at the naris
Answer: A
Rationale: While X-ray is the gold standard, pH testing of aspirate is the most reliable
bedside method. Auscultation is no longer considered reliable.
8. A nurse is suctioning a patient with a tracheostomy. What is the maximum
amount of time the nurse should apply suction?
A. 5 seconds
B. 10 to 15 seconds
C. 20 to 30 seconds
D. As long as secretions are visible
Answer: B
Rationale: Suctioning should be limited to 10-15 seconds per pass to prevent hypoxia and
vagal stimulation.
