TEST BANK QUESTIONS AND CORRECT
ANSWERS LATEST UPDATE
1. A nurse is preparing to establish a sterile field. Which of the following actions would result
in contamination of the sterile field?
A. Placing the sterile tray on a bedside table that is slightly below waist level.
B. Opening the outermost flap of the sterile kit away from the body.
C. Keeping a 1-inch border around the edge of the sterile drape.
D. Pouring sterile saline into a container while holding the bottle 2 inches above the field.
Answer: A
Conceptual Explanation: Any object or field below the waist level is considered
contaminated in surgical asepsis. The table must be at or above the waist.
2. When performing tracheostomy suctioning on an adult patient, what is the maximum
recommended duration for each suction pass?
A. 5 seconds
B. 10 to 15 seconds
C. 20 to 30 seconds
,D. Until the airway is clear
Answer: B
Conceptual Explanation: Suctioning should be limited to 10-15 seconds to prevent
hypoxia and vagal stimulation. Longer durations can lead to significant oxygen
desaturation.
3. A patient is receiving a continuous intravenous infusion of Heparin. Which laboratory value
is the priority for the nurse to monitor?
A. Activated Partial Thromboplastin Time (aPTT)
B. International Normalized Ratio (INR)
C. Prothrombin Time (PT)
D. Platelet Count
Answer: A
Conceptual Explanation: aPTT is used to monitor the therapeutic effect of unfractionated
heparin. PT/INR is used for Warfarin therapy.
4. The nurse is inserting a nasogastric (NG) tube. What is the most reliable bedside method to
verify the correct placement of the tube before starting a feeding?
A. Auscultating air injected into the stomach.
B. Checking the pH of aspirated gastric contents.
C. Observing the patient for coughing or choking.
, D. Submerging the end of the tube in water to check for bubbles.
Answer: B
Conceptual Explanation: While X-ray is the gold standard for initial placement, checking
pH (usually < 5.5) is the most reliable bedside method. Auscultation is no longer
considered evidence-based for accuracy.
5. Which clinical manifestation would lead a nurse to suspect that an IV site has developed
phlebitis rather than infiltration?
A. Coolness of the skin around the insertion site.
B. Palpable cord along the vein.
C. Dampness of the dressing.
D. Pitting edema in the extremity.
Answer: B
Conceptual Explanation: Phlebitis is inflammation of the vein characterized by warmth,
redness, and a palpable cord. Infiltration is characterized by coolness, pallor, and swelling.
6. A nurse is administering a Z-track intramuscular injection. What is the primary purpose of
this technique?
A. To prevent medication from leaking into the subcutaneous tissue.
B. To ensure the needle reaches the bone for faster absorption.
C. To reduce the pain of the injection by numbing the skin.
