COMPREHENSIVE EXAM 2026/2027
QUESTIONS AND ANSWERS
1. A nurse is caring for a client who has a prescription for a 24-hour urine collection. Which of
the following actions should the nurse take first?
A. Place a sign on the bathroom door as a reminder.
B. Discard the first voiding and note the start time.
C. Keep the collection container in a basin of ice.
D. Verify the client’s identity using two identifiers.
Answer: B
Conceptual Explanation: To begin a 24-hour urine collection, the nurse must discard the
first voiding to ensure the timing starts with an empty bladder, then collect all subsequent
urine for exactly 24 hours.
2. A nurse is assisting with the plan of care for a client who has a stage 2 pressure injury.
Which of the following interventions should the nurse include?
A. Place the client in a high-Fowler’s position.
,B. Cleanse the wound with hydrogen peroxide.
C. Massage the reddened area around the injury.
D. Apply a hydrocolloid dressing to the wound.
Answer: D
Conceptual Explanation: Hydrocolloid dressings are appropriate for stage 2 pressure
injuries as they maintain a moist healing environment and protect the wound from
contamination.
3. A nurse is preparing to administer an enteral feeding via a nasogastric tube. Which of the
following pH levels of the gastric aspirate indicates correct tube placement?
A. pH of 7.5
B. pH of 6.0
C. pH of 3.5
D. pH of 8.0
Answer: C
Conceptual Explanation: Gastric contents are typically acidic with a pH of 1.0 to 4.0. A pH
of 3.5 strongly suggests the tube is in the stomach rather than the intestines or respiratory
tract.
, 4. A nurse is caring for a client who is post-operative and has a prescription for sequential
compression devices (SCDs). Which of the following actions should the nurse take?
A. Ensure two fingers can fit between the sleeve and the leg.
B. Apply the sleeves while the client is sitting in a chair.
C. Place the sleeve under the client’s leg with the inflation port at the knee.
D. Set the pressure to 60 mmHg for each cycle.
Answer: A
Conceptual Explanation: Checking for a two-finger space ensures the sleeves are tight
enough to provide compression but not so tight that they impede circulation when not
inflated.
5. A nurse is teaching a client about a low-sodium diet. Which of the following food choices
should the nurse identify as having the highest sodium content?
A. Fresh orange juice
B. Canned tomato soup
C. Brown rice
D. Poached eggs
