2026/2027 400 VERIFIED REAL EXAM QUESTIONS WITH
DETAILED ANSWERS & RATIONALES
1. A nurse is preparing to insert an indwelling urinary catheter for a
female client. Which action demonstrates proper sterile technique?
A. Placing the sterile field at waist level
B. Using sterile gloves only without a sterile drape
C. Opening the sterile kit with the top flap opened toward the nurse
D. Using clean gloves for the entire procedure
E. Placing the catheter kit on the overbed table
A. Placing the sterile field at waist level
RATIONALE: The sterile field must be maintained at or above waist level
to prevent contamination. The top flap of a sterile kit should be opened
away from the body. Sterile gloves alone are insufficient; a sterile drape
is required. Clean gloves are not appropriate for an indwelling catheter
insertion.
2. A nurse is assessing a client who has been receiving total parenteral
nutrition (TPN) for 7 days. Which finding indicates a metabolic
complication?
,A. Blood glucose 180 mg/dL
B. Serum potassium 4.0 mEq/L
C. Weight gain of 0.5 kg in 24 hours
D. Blood glucose 250 mg/dL with polyuria
E. Serum sodium 138 mEq/L
D. Blood glucose 250 mg/dL with polyuria
RATIONALE: Hyperglycemia is a common metabolic complication of TPN
due to the high dextrose concentration. A blood glucose of 250 mg/dL
with polyuria indicates hyperglycemia requiring intervention. Blood
glucose of 180 mg/dL is elevated but less concerning. Weight gain of 0.5
kg in 24 hours is within expected range. Normal potassium is 3.5-5.0
mEq/L and sodium is 136-145 mEq/L.
3. A nurse is providing discharge teaching to a client with heart failure.
Which statement by the client indicates understanding of dietary
restrictions?
A. "I can use salt substitutes freely to flavor my food"
B. "I should limit my daily fluid intake to 2 liters"
C. "I can eat canned soups if I rinse them first"
D. "I should avoid adding salt to food but can eat processed meats"
E. "I need to drink at least 3 liters of water daily"
B. "I should limit my daily fluid intake to 2 liters"
RATIONALE: Clients with heart failure typically require fluid restriction
of 1.5-2 liters daily to prevent fluid overload. Salt substitutes contain
potassium and should be used cautiously. Canned soups are high in
sodium even after rinsing. Processed meats contain high sodium
,content and should be avoided. Excessive fluid intake worsens heart
failure symptoms.
4. A nurse is caring for a client with a chest tube following a
thoracotomy. Which finding requires immediate intervention?
A. Continuous bubbling in the water seal chamber
B. Intermittent bubbling in the suction control chamber
C. 100 mL of sanguineous drainage in the first hour
D. Tidaling in the water seal chamber with respirations
E. Drainage of 50 mL in 4 hours
A. Continuous bubbling in the water seal chamber
RATIONALE: Continuous bubbling in the water seal chamber indicates
an air leak that requires immediate intervention to prevent
pneumothorax or tension pneumothorax. Intermittent bubbling in the
suction control chamber is normal. Sanguineous drainage of 100 mL in
the first hour is expected. Tidaling in the water seal chamber is normal.
Drainage of 50 mL in 4 hours is acceptable.
5. A nurse is administering digoxin to a client with atrial fibrillation.
Which assessment finding indicates digoxin toxicity?
A. Heart rate 72 beats per minute
B. Serum potassium 4.2 mEq/L
C. Visual disturbances with yellow halos
D. Blood pressure 130/80 mm Hg
E. Respiratory rate 18 breaths per minute
, C. Visual disturbances with yellow halos
RATIONALE: Visual disturbances including yellow-green halos or blurred
vision are classic signs of digoxin toxicity. Other signs include nausea,
vomiting, bradycardia, and cardiac dysrhythmias. Normal heart rate is
60-100 bpm. Normal potassium is 3.5-5.0 mEq/L. Blood pressure of
130/80 is within normal limits. Respiratory rate of 18 is normal.
6. A nurse is caring for a client with a new diagnosis of diabetes
mellitus type 1. Which statement indicates the client understands
insulin administration?
A. "I will store my unopened insulin vials in the freezer"
B. "I can mix NPH and regular insulin in the same syringe"
C. "I should rotate injection sites only on my abdomen"
D. "I need to inject insulin intramuscularly for best absorption"
E. "I can use the same syringe multiple times to save money"
B. "I can mix NPH and regular insulin in the same syringe"
RATIONALE: NPH and regular insulin can be mixed in the same syringe,
with regular drawn first to prevent contamination of the vial. Insulin
should be stored in the refrigerator, not freezer. Rotation should include
multiple sites (abdomen, thighs, arms). Insulin is administered
subcutaneously, not intramuscularly. Syringes are for single use only.
7. A nurse is performing a neurological assessment on a client. Which
finding is an early sign of increased intracranial pressure (ICP)?
