LPN/LVN NCLEX-PN Practice Exam 3 (2026/2027) UPDATE |SBON
1. A nurse is preparing to administer digoxin to a client. Which of the following
vital signs should the nurse check before administration?
A. Blood Pressure
B. Apical Pulse
C. Respiratory Rate
D. Temperature
Answer: B
Rationale: The apical pulse must be checked for one full minute before administering
digoxin; the medication should be held if the pulse is below 60 bpm in adults.
2. Which of the following laboratory values should a nurse monitor for a client
receiving warfarin therapy?
A. PTT
B. Platelet Count
C. INR
D. Hemoglobin
Answer: C
Rationale: INR (International Normalized Ratio) and Prothrombin Time (PT) are used to
monitor the effectiveness of warfarin therapy.
,3. A client with Type 1 Diabetes is found sweaty, shaky, and confused. What is
the nurse’s priority action?
A. Administer 15g of fast-acting carbohydrates
B. Give a scheduled dose of insulin
C. Check the client’s temperature
D. Call the physician to report hyperglycemia
Answer: A
Rationale: The client is showing signs of hypoglycemia; the priority is to provide 15g of
simple carbohydrates to raise blood glucose levels.
4. What is the appropriate oxygen flow rate for a client with chronic obstructive
pulmonary disease (COPD) to prevent respiratory depression?
A. 12-15 L/min
B. 5-6 L/min
C. 8-10 L/min
D. 1-2 L/min
Answer: D
Rationale: Clients with COPD often rely on a hypoxic drive to breathe; high levels of
oxygen can suppress this drive, so low-flow oxygen is preferred.
5. Which assessment finding is most indicative of fluid volume overload in a
client with heart failure?
A. Flattened neck veins
B. Dry mucous membranes
C. Tachycardia
D. Crackles in the lungs
Answer: D
Rationale: Crackles (rales) indicate fluid in the alveoli, a common sign of pulmonary
edema associated with heart failure and fluid overload.
, 6. A nurse is caring for a client who is 2 hours post-operative. Which finding
should be reported immediately?
A. Pain level of 4 on a scale of 10
B. Oral temperature of 99.0 F
C. Serosanguinous drainage on the dressing
D. Urine output of 20 mL per hour
Answer: D
Rationale: Urine output less than 30 mL/hr can indicate poor renal perfusion or shock and
must be reported immediately.
7. When performing tracheostomy care, which action should the nurse take?
A. Hyper-oxygenate the client before suctioning
B. Apply suction for 30 seconds at a time
C. Use clean technique for the entire procedure
D. Cut a 4x4 gauze pad to fit around the tube
Answer: A
Rationale: Hyper-oxygenation helps prevent hypoxia during the suctioning procedure.
8. Which position is most appropriate for a client immediately following a liver
biopsy?
A. High Fowler’s
B. Left side-lying
C. Right side-lying
D. Supine with head elevated
Answer: C
Rationale: Placing the client on the right side applies pressure to the biopsy site to prevent
bleeding.
