Section 1: Fundamentals of Nursing (Questions 1-50)
1. A nurse is preparing to administer an enteral feeding to a client via a
nasogastric (NG) tube. Which of the following actions should the nurse take
first?
A. Flush the tube with 30 mL of water.
B. Verify the placement of the tube by checking the pH of the gastric aspirate.
C. Elevate the head of the bed to at least 30 degrees.
D. Confirm the feeding formula with the provider's order.
Correct Answer: B
Rationale: Patient safety is the priority. Verifying NG tube placement (via X-
ray confirmation or pH testing of aspirate) is the most critical step before
administering any feeding to prevent aspiration.
2. A client is prescribed 500 mg of a medication. The available medication is in
a liquid concentration of 250 mg/5 mL. How many mL should the nurse
administer?
A. 5 mL
B. 10 mL
,C. 15 mL
D. 20 mL
Correct Answer: B
Rationale: Use the formula: (Desired / Available) x Volume = (500 mg / 250
mg) x 5 mL = 2 x 5 mL = 10 mL.
3. A nurse is caring for a client who is postoperative and has an indwelling
urinary catheter. Which of the following interventions is most important to
prevent a catheter-associated urinary tract infection (CAUTI)?
A. Empty the drainage bag every 8 hours.
B. Ensure the catheter tubing is secured to the client's thigh.
C. Cleanse the perineal area with an antiseptic solution twice daily.
D. Maintain a closed urinary drainage system.
Correct Answer: D
Rationale: Maintaining a closed system is the single most effective measure to
prevent bacteria from entering the urinary tract. Breaking the closed system
allows for contamination.
4. A client has an order for a continuous IV infusion of 0.9% Normal Saline at
125 mL/hr. The IV tubing has a drop factor of 15 gtt/mL. What is the drip rate
in gtt/min?
A. 15 gtt/min
B. 21 gtt/min
C. 31 gtt/min
D. 40 gtt/min
Correct Answer: C
Rationale: Formula: (Volume (mL) / Time (min)) x Drop Factor = (125 mL /
60 min) x 15 gtt/mL = 2.08 x 15 = 31.25 gtt/min. Round to 31 gtt/min.
,5. A nurse is assessing a client's wound and notes purulent, yellow-green
drainage with a foul odor. The nurse should document this finding as:
A. Serous drainage
B. Serosanguineous drainage
C. Sanguineous drainage
D. Purulent drainage
Correct Answer: D
Rationale: Purulent drainage is thick and may be yellow, green, or brown,
indicating an infection. Serous is clear, serosanguineous is pink/watery, and
sanguineous is bloody.
6. A nurse is providing teaching to a client about maintaining a healthy
immune system. Which of the following statements by the client indicates a
need for further teaching?
A. "I will try to get at least 7-8 hours of sleep each night."
B. "I am going to stop taking my daily multivitamin."
C. "I should try to manage my stress with meditation."
D. "I will make sure to wash my hands frequently."
Correct Answer: B
Rationale: A balanced diet and proper nutrition are crucial for a healthy
immune system. Stopping a multivitamin abruptly, without consulting a
provider, could indicate a misunderstanding of nutritional needs.
7. A nurse is preparing to transfer a client from a bed to a chair. Which of the
following actions should the nurse take to prevent a back injury?
A. Keep the feet close together for a solid base of support.
B. Bend at the waist to lift the client.
, C. Position the chair close to the bed.
D. Use a gait belt and have the client hold onto the nurse's neck.
Correct Answer: C
Rationale: Positioning the chair as close as possible to the bed reduces the
distance the client needs to be moved, minimizing the physical strain on the
nurse's back. The nurse should also use proper body mechanics (e.g., wide
base of support, keep back straight, use a gait belt).
8. A nurse is assessing a client for signs of dehydration. Which of the following
findings is an early indicator?
A. Hypotension
B. Decreased skin turgor
C. Elevated temperature
D. Thirst
Correct Answer: D
Rationale: Thirst is one of the earliest subjective indicators of fluid volume
deficit. Other signs like hypotension, poor turgor, and elevated temperature
occur later as the condition progresses.
9. A client is receiving a blood transfusion. Fifteen minutes after the start of
the transfusion, the client reports chills and low back pain. The nurse's
priority action is to:
A. Slow the infusion rate.
B. Notify the healthcare provider.
C. Stop the transfusion.
D. Administer an antihistamine.
Correct Answer: C
