A. Placing the catheter on a clean surface
B. Wearing clean gloves to insert the catheter
C. Opening the catheter kit using the outer edges of the wrapper
D. Touching the sterile catheter with bare hands
Rationale: Opening the catheter kit using the outer edges maintains sterility.
Sterile technique is critical in invasive procedures like catheterization.
2. Which site is preferred for intramuscular injections in adults due to low risk of
nerve or blood vessel injury?
A. Dorsogluteal
,B. Deltoid
C. Ventrogluteal
D. Vastus lateralis
Rationale: The ventrogluteal site is safest and least likely to hit nerves or blood
vessels in adults.
3. When performing a wound dressing change, the nurse must first:
A. Perform hand hygiene
B. Apply sterile gloves
C. Remove the old dressing
D. Assess the drainage
Rationale: Hand hygiene is the first step to prevent infection transmission during
any nursing procedure.
4. Which of the following oxygen delivery systems delivers the most precise
oxygen concentration?
A. Simple face mask
B. Venturi mask
C. Nasal cannula
D. Partial rebreather mask
Rationale: A Venturi mask delivers a precise and adjustable oxygen
concentration, ideal for COPD patients.
,5. The nurse is preparing to administer 10 units of insulin subcutaneously. What
angle should the nurse use for injection?
A. 15 degrees
B. 45–90 degrees
C. 30 degrees

A. Call for a code
B. Begin abdominal thrusts (Heimlich maneuver)
C. Start CPR

A. Have the patient cross their legs
B. Use a cuff too small for the arm
C. Ensure the cuff is at heart level
D. Place the cuff over clothing
, Rationale: The blood pressure cuff must be at heart level to get an accurate
reading.
8. Which action is part of the “Six Rights” of medication administration?
A. Right technique
B. Right time
C. Right temperature
D. Right prescription number
Rationale: The “right time” is one of the Six Rights that help prevent medication
errors.
9. Which of the following is an early sign of hypoxia?
A. Cyanosis
B. Restlessness
C. Bradycardia
D. Hypotension
Rationale: Restlessness and anxiety are early signs of inadequate oxygenation.
10. A nurse is collecting a sterile urine specimen from a catheter. Where should
