LPN Fundamentals Practice Test Questions
Question 1 of 5
The nurse is assisting in caring for a client with a tracheal tube attached to a ventilator when the high-pressure alarm sounds. The nurse checks the client and system for which most likely cause?
Correct Answer: D
Rationale: A high-pressure alarm indicates resistance in the ventilator circuit; accumulation of secretions (D) is the most likely cause, obstructing airflow. A cuff leak (A) or disconnection (C) triggers low-pressure alarms. A loose connection (B) is less common for high pressure. D is correct. Rationale: Secretions block the tube, increasing pressure needed to ventilate, a frequent issue in intubated patients, requiring suctioning, per ventilator troubleshooting protocols. This distinguishes it from leaks or disconnections, ensuring timely airway clearance.
Question 2 of 5
Which color tag will be given by the triage nurse to a client assigned to class IV, during a mass casualty situation?
Correct Answer: B
Rationale: Class IV in mass casualty triage (black tag, B) indicates expectant/deceased, unlikely to survive. Red (A) is immediate. Green (C) is minor. Yellow (D) is delayed. B is correct. Rationale: Black tags prioritize resources for salvageable patients, a standard in disaster triage, per START protocol.
Question 3 of 5
The nurse is caring for a client with a spinal cord injury who is at risk for deep vein thrombosis (DVT). Which intervention should the nurse implement?
Correct Answer: A
Rationale: Sequential compression devices (A) prevent DVT in immobile SCI patients. Active exercise (B) isn't feasible. Anticoagulants (C) need orders. Massage (D) risks emboli. A is correct. Rationale: Compression enhances venous return, reducing stasis, per DVT prophylaxis in SCI, a standard intervention.
Question 4 of 5
Which of the following reasons is the most important, as well as the most widely accepted, reason for nurses using nursing process?
Correct Answer: C
Rationale: The nursing process's most important and widely accepted reason is facilitating communication with the healthcare team. This structured approach assessment, diagnosis, planning, implementation, evaluation creates a common language, ensuring physicians, therapists, and nurses align on client care. For example, documenting a client's respiratory distress via the process informs all team members, enhancing coordination. While it builds nursing knowledge, addresses health problems, and standardizes care, communication is the linchpin, enabling collaborative, effective interventions across disciplines.
Question 5 of 5
A client asks you how to best prevent vaginal infections. Your best answer would include which of the following statements?
Correct Answer: B
Rationale: Explaining that vaginal pH stops many bacteria is true and educational, highlighting the body's natural defense against infections like bacterial vaginosis. Vinegar douches disrupt this balance, cranberry juice aids urinary health not vaginal, and medications aren't preventive norms. This empowers the client with knowledge, a key nursing role in infection prevention.
