LPN Fundamentals Practice Test Questions
Question 1 of 5
A nurse is caring for several clients in a community health setting and wants to engage in secondary prevention activities with a client who does not exhibit symptoms of illness. Which activity meets this goal?
Correct Answer: B
Rationale: Secondary prevention detects disease early in asymptomatic clients, halting progression perfect for a community setting. Screening for hearing loss fits this, identifying issues like age-related decline before symptoms like isolation emerge, enabling timely aids or therapy. Teaching a low-fat diet is primary, preventing illness onset, not detecting it. Referring to smoking cessation is primary too, averting lung disease, not finding it. Planning care for COPD is tertiary, managing a known condition. Hearing screening aligns with nursing's goal to catch silent problems studies show early detection cuts disability making it ideal for a well client. This proactive step ensures health maintenance, leveraging community access to intervene before symptoms disrupt life, a key nursing strategy for population wellness.
Question 2 of 5
The nurse is planning to suction a client through a tracheostomy tube. Which is the amount of time for application of suction during withdrawal of the catheter?
Correct Answer: A
Rationale: Suctioning through a tracheostomy should last 10 seconds (A) during withdrawal to minimize hypoxia and trauma, per standard guidelines. Longer times 25 (B), 30 (C), or 35 (D) seconds increase risks of oxygen depletion and mucosal injury. A is correct. Rationale: Limiting suction to 10 seconds balances secretion removal with oxygenation preservation, a key safety measure in airway management, preventing complications like atelectasis or arrhythmias, as endorsed by AACN and ATS.
Question 3 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 4 of 5
When caring for a client with a head injury that may have involved the medulla, the nurse bases assessments on the knowledge that the medulla controls a variety of functions. Which functions will the nurse assess? Select all that apply.
Correct Answer: C
Rationale: The medulla controls vital functions like pulse rate (C), breathing (B), and swallowing. Balance (A) is cerebellar. Temperature regulation (D) is hypothalamic. C is correct for CSV. Rationale: Medulla injury disrupts cardiac rhythm, a critical assessment in head trauma, per neuroanatomy, as it houses the vagus nerve and cardiovascular centers, unlike other regions controlling non-vital functions.
Question 5 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.
